The Cat Photo That Sold for 690,000 Dollars ! How Did He Do It

  • Chris Torres first posted pixelated art of his cat, Marty, in April of 2011.
  • The collection is known as Nyan Cat. When it finally became an NFT, a bidding war took place.
  • But Torres said frequent engagement with the community is a big part of the NFT’s success.

In 2011, Chris Torres began making pixelated art of a cat in a pastry body flying through space with a rainbow trail that he called Nyan Cat. The character was a depiction of his real cat, Marty, a Russian blue who died in 2012.

“There’s kind of an art form on the internet where it’s like a lot of cute animals that are paired with edible bodies, like apple bodies or cake bodies. So this one was kind of my take on it with a breakfast-pastry body,” Torres said.

Torres, a big fan of retro video games, said the image’s pixelated feature was inspired by Nintendo’s graphics.

He first posted the GIF on Twitter and Tumbler in April 2011. A few days later, someone made a YouTube video of Nyan Cat with music in the background. Torres told Insider he didn’t know who had created it at the time, though today he works with that creator. To date, that video has raked in almost 200 million views.

How Nyan Cat became an NFT collection

To create Nyan Cat, Torres used Adobe Fireworks, a now-discontinued program similar to Flash that he said crashed constantly. But it challenged him to preserve the traditional pixelated look.

Torres has made many iterations of Nyan Cat over the years but didn’t do much with them.

Then he learned about non-fungible tokens through a friend who sent him a link to an article about SuperRare, an NFT marketplace. At first the idea that artists could get recognition and a decent amount of financial compensation for their work seemed too good to be true, he said.

“I was making art all the time, but I wasn’t getting the recognition that I am getting today,” Torres said.

He continued, “It was basically me versus the world in terms that I had people and companies approach me and they would just try to offer free publicity or they would say they would tweet about it or just post it somewhere. Then that would be my payment for them to use my work commercially. And you know, they make a lot of money out of it, to be frank.”

Torres has always been an artist but never made enough from his artwork alone to pay the bills. He had a day job in IT, until he got laid off in April 2020 because of the COVID-19 pandemic, he said.

“I was literally living on unemployment and we had just bought a house and I was furloughed months before,” Torres said. “So we were in a very stressful situation, but then the NFTs came along and just totally saved our lives.”

SuperRare was the first NFT marketplace he applied to in January 2021, but it took the platform several months to accept him. While he was waiting, Foundation, another NFT marketplace, contacted him.

Torres took the old files he had of Nyan Cat and remastered them in HD quality but didn’t change the pixelated feature. The artworks listed on Foundation were uploaded as MP4 files, while the main collection remained GIFs.

The first and original Nyan Cat sold for 300 ETH in February 2021 after an unexpected bidding war took place. That was equivalent to about $690,000, based on ETH’s trading price of about $2,300 on Monday. Torres had initially set the floor price at 3 ETH.

By the time Torres entered the market, lots of people already knew Nyan Cat as a GIF or meme. But that wasn’t what got Nyan Cat going as an NFT, Torres said.

“From there, not only was I just saying, ‘Hey, this is my piece here,’ I started interacting with people on Twitter, on Instagram, basically the NFT community,” Torres said. “And I think that’s what actually brought the value to the piece itself, just the whole community factor behind it all. People seeing that I’m active and not just here trying to





make money.”

In March 2021, just a month after Torres sold his NFT, the digital artist known as Beeple sold an NFT of his work for a record $69 million. Last year, during the crypto boom that preceded the ongoing market slump, NFT sales reached a total valuation of  $41 billion, according to Chainalysis.

While not all NFT creators are as successful as Torres, the most important things that drive the prices of NFTs like Nyan Cat are the community and team behind the project, Alex Salnikov, the head of product and cofounder of Rarible, said.

“Once the collection manages to attract a strong community of people who see value in the project above just the floor price and flip potential, the NFT becomes more of a status symbol rather than a simple JPEG, and that’s when things can really start to take off,” Salnikov said.

He continued: “That is part of the reason why so many popular and expensive NFTs tend to be so strongly intertwined with internet and meme culture. Those NFTs represent concepts that are already valuable to the Web3 crowd. The Nyan Cat is a fantastic example of this phenomenon.”

To date, the Nyan Cat collection has eight single-copy pieces of art. All have been sold for over six figures.

“I wanted people to own Nyan Cat. Back when I was doing the one-to-ones, they went straight to very specific buyers, and those people, they’re what’s called ‘diamond hands’ — they don’t want to let go of them very easily or at all,” Torres said.

Is AJAX Bad for SEO? Not Necessarily. Here’s Why.

The world of web development has come a long way since the invention of the World Wide Web.

The technologies and techniques that engineers and web developers use to build websites seem to dramatically change with increasing frequency. The way search engines like Google categorize and understand websites has had to become more sophisticated to keep up with it.

AJAX is one of the technologies that developers use to improve user experience and make websites that have more functionality. It is widely used by websites across the internet. Historically, AJAX has been prohibitively difficult for search engines to process and has thus posed a problem for website owners seeking to rank on Google.

Is AJAX SEO-friendly? How do you get Google and other search engines to correctly crawl and index your AJAX website? We’ll explore these questions and provide some recommendations.

What Is AJAX?
To understand why AJAX has been so problematic for SEO teams and website owners, it helps to understand what AJAX is and what it does.

AJAX stands for Asynchronous JavaScript and XML. It’s a protocol that allows for a browser to make HTTP requests with servers without having to refresh the page.

AJAX can send and receive information in:

Text files
Normal web applications send information between you and the server using synchronous HTTP requests. This means that the page has to stop and wait for a server response to reload whenever the page gets new content.

AJAX, meanwhile, loads JavaScript asynchronously between you and the server in the background and retrieves new content in real time after the page has loaded. Rather than loading the data via an HTTP via the URL bar, AJAX uses the XMLHttpRequest to update individual parts of the page while the page as a whole remains interactive.

Imagine the way a Twitter feed works. You follow any number of people who likely tweet multiple times a day. Normally, this is indicated by the “Load More Tweets” button at the top or the bottom of your feed.

Imagine having to hit the “refresh” button in your browser to update your Twitter feed rather than just hitting the button on the page itself and having it instantly update? This would be frustrating, time consuming and needlessly tiresome.

These are the types of problems that AJAX solves. It has other similar applications as well. It makes the collapsable information boxes you see on many modern websites possible, or the “load more” functionality seen at the bottom of blog articles. The modern internet would be very different without it.

That said, AJAX comes with its pitfalls.

Is AJAX SEO-Friendly
Can Google crawl AJAX content? The short answer is yes. The longer answer is yes, but it’s a little more complicated.

Single page web applications that use AJAX frameworks have historically been very problematic from an SEO standpoint and caused problems such as:

Crawling issues: Important content was hidden behind unparsed JavaScript which only rendered on the client side, meaning Google would essentially just see a blank screen
Broken website navigation and navbar issues
Cloaking: Webmasters might unintentionally create content for the user that’s different from what the web crawlers see, resulting in ranking penalization
For years, Google advised webmasters to make use of the AJAX crawling scheme to signal to Google that a website had AJAX content, as advised in its 2009 proposal. The AJAX crawling scheme made use of the _escaped_fragment parameter. This parameter instructed Google to get a pre-rendered version of a web page with static, machine-readable HTML that Google could parse and index. The server would instruct the web crawler to crawl a different page than what was available in the source code, similar to how dynamic rendering works today.

Then, things changed. In 2015 Google announced that Google was now generally able to crawl, read and parse JavaScript without any issues, making the AJAX crawling scheme obsolete. This was the point when Google began recommending dynamic rendering solutions instead.

SEO Problems That Can Occur With AJAX
ajax seo problems
Google might claim that it’s able to crawl and parse AJAX websites, yet it’s risky to just take its word for it and leave your website’s organic traffic up to chance. Even though Google can usually index dynamic AJAX content, it’s not always that simple.

Some of the things that can go wrong include:

Buried HTML
If important content is buried beneath AJAX JavaScript, the crawler might have more difficulty accessing it. This can delay the crawl, render, index and ranking process by a week or more.

To make sure your content gets ranking on Google effectively, make sure your important content is stored in HTML so it can be indexed by Google and other search engines — or make sure your content is prerendered so that Google can easily access it.

Missing Links
Google uses your website’s internal links to understand how your content relates to each other, and your external links as proof that your content uses authoritative, credible and trustworthy information to substantiate it.

For this reason, it’s very important that all your links be readable and not buried under AJAX JavaScript.

How AJAX Impacts SEO
So does that mean you don’t need to worry about whether Google can crawl your AJAX website? Not necessarily.

While it’s true that the AJAX crawling scheme proposed in 2009 is now obsolete, we only have Google’s assurances that its web crawlers can now crawl and parse JavaScript websites.

If we take a look at the exact wording of Google’s deprecation of the AJAX crawling scheme, it says:

“… as long as you’re not blocking Googlebot from crawling your JavaScript or CSS files, we are generally able to render and understand your web pages like modern browsers.”

The operative word here is generally. This is essentially Google’s way of covering its tracks, shrugging its shoulders when it comes to AJAX websites, and saying “it’s not our problem.”

So, while you no longer need to use special workarounds to make sure that Google can crawl your website, it’s still within your best interest as a website owner to ensure that Google can crawl your website.

So, what are the rules now?

For one thing, Google now advocates the use of progressive enhancement, a philosophy of web development that emphasizes the importance of the content itself before anything else.

One way you can adhere to these standards is by using the History API with the pushState() function, which changes the path of the URL that appears in the client-side address bar.

Using pushState enables you to have the speed and performance benefits of AJAX while still being crawlable. The URL accurately reflects the “real” location of the web page giving a more accurate picture of the content.

Another thing that Google pays attention to now is what’s known as #!, or “hashbang” markup.

Google looks for #! parameters to identify dynamic URLs and treat them differently. It takes everything after the hashtag and passes it to the website as a URL parameter, then requests the static version of the page that it can read, index and rank.

How You Can Make Your AJAX Website Crawlable
how to crawl ajax website
It’s completely possible to optimize a JavaScript website that not only displays correctly but also is indexed and ranked by Google without any missing content, crawl errors or any other problems that can affect your search rankings.

Some things to look out for include:

Optimize URL Structure
It’s strongly advised that you use the pushState History API in place of the _escaped_fragment protocol. The function updates the URL in your address bar so that any JavaScript content displays without any issues.

A clean URL means using short phrases and text in a way that makes it easy to tell what the page is about.

Optimize Website Speed
When the client-side browser creates a DOM, it can end up creating a lot of bloated coding inside your HTML which bogs down your page speed and subsequently makes it harder for Googlebot to crawl your content in one sitting. Make sure you remove any render-blocking resources so that Google can parse your CSS and scripts efficiently.

AJAX Websites Can Work for You
AJAX websites have been a headache for website owners who want to provide their users with the best possible user experience. Most of the issues that have historically been problems seem to have been resolved, but AJAX can still be cumbersome for your website’s maintenance and detrimental to your website’s SEO health.

Use the History API function so you can have the performance benefits and user experience perks of AJAX while still ensuring your website can reach top-ranking positions in Google search results.

Better yet, use Prerender to make sure your AJAX website is crawled seamlessly every time Google visits your website.

How To Become A Web Developer in 2022 – A Complete Guide You cant Miss From

How did you feel when you created your first login form on a web page after so many trials and tested templates (don’t say that you created everything from scratch…)? … How did you feel when you give the layout to your first web application after multiple changes (Yes…you took the reference of some other websites or template as per requirement…)?… How did you feel when you successfully handled thousands of users’ sensitive information at the backend to build an application (It was scary…)?

Most of the web developers go through all the above phases and initially it might be frustrating for some of them but the overall feeling is really exciting and amazing when they see their website is live and people are using it all over the world. A web developer is responsible for so many tasks from gathering requirements to designing a website, handling it’s backend part and also making it live successfully for users.
Every year new technology and tools are coming out in industries to boost developers’ productivity and to make the website better for users. It becomes challenging for them to stay on top of the web development game. Today we are going to discuss a complete map to become a web developer in 2022. This will be a practical guideline for all kinds of developers (front-end, backend, and full-stack).

Decide Your Goal or Path First

We will discuss a lot of technologies, trends, and tools but we don’t want you to get overwhelmed, so you need to decide first what do you want to do to become a web developer because that will help you to choose the right tools and technology to learn. There are a lot of different reasons to become a web developer some of the options are given below…

You want to work for a company as a web developer which is the most popular and common reason.
You want to work as a freelance developer to start your own business or agency.
You can become a consultant for other companies.
You can create your own app to make money.
Code as a hobby.

From the above area of interest or goal, you can pick up the right tools and technology that is applicable to your goal. If your goal is to become just a front end developer you can choose the tools and technology of frontend development. The same goes for backend and full-stack development.

Basic Tools and Software for Web Development
Computer & OS: You can’t write code without a computer and OS running on it. To learn web development you don’t need any kind of fancy computer (If you have it’s good…). You can use any kind of mid-range laptop or desktop. For the operating system, you can use MacOS, Windows (Latest version) or Linux whatever is comfortable for you.
Text Editor / IDE: No doubt VSCode is good for most cases and most languages. It has good performance, great extensions, built in terminal and ton of features as well. In 2019 StackOverFlow survey VSCode was developers first preference as well. You also have some other good options such as Sublime Text or Atom. If we talk about IDEs so Visual Studio ( or C#), Eclipse and Netbeans (Java). are good options.
Web Browser: Most of developers first choice is either Chrome or Firefox. Chrome is fast and it uses V8 engine (JavaScript engine). Firefox has also come a long way and some of it’s good stuff is not in chrome browser. Both the browsers have fantastic dev-tools to to troubleshoot the issues in web development.
Terminal: You will be working a lot with CLI using some system commands. You can use the default or third-party terminal for your web development project. Bash, Zsh, Powershell, Git Bash, iTerm, Hyper these all are options available to use.
Design (Optional): Not everbody needs to learn this. In companies there is a specific team to make images, logo or sketches but if you are working as a freelancer then you may have to learn Adobe XD, Photoshop, Sketch or Figma.
Start With HTML and CSS

HTML and CSS are the basic building blocks of web development. No matter how advanced your web app is or what frameworks and backend language you are using, you will have to build your frontend application using HTML and CSS. So this is the first thing to learn in web development.

HTML5 (Semantic elements, attributes, doctype, etc)
CSS Fundamentals Colors, fonts, positioning, box-model etc.
CSS Grid and Flexbox to align things or create coloumns.
CSS Custom Properties
Responsive Layouts

Your application should be viewable and usable on all kinds of devices such as smartphones, tablets, desktop, iPad or any other screen size devices. So it’s important to learn about creating a responsive design or layout. Let’s see some important topics for that.

Learn how to set the viewport
Media queries for different screen size.
Fluid Widths
rem units
Mobile First
Custom Reusable CSS Components

Instead of relying on large CSS frameworks like Bootstrap it’s good to create your own modular, reusable CSS components to use in your projects. You don’t need to import the complete library if you build your own custom design. You create the component that you only need for the particular UI.
A new trend Saas also has come out recently that helps in writing CSS code more efficiently. If you already know CSS then you don’t need to put so much effort into learning Saas. Saas is a CSS preprocessor that adds more functionality to standard CSS and makes it more efficient. You can use variables, nesting, conditionals to reduce the repetition of CSS and make it more efficient. You can also create your separate Saas file for each reusable component. Sass really saves a lot of time so you should definitely learn it in 2022.

CSS Frameworks

Learning CSS frameworks is a bit less popular than last year but still very relevant or useful for developers who are not good with design. There are a lot of popular CSS frameworks available to use, some of them are given below.

Bootstrap is the most popular CSS framework to learn. Learning bootstrap helps in learning other frameworks as well.
Tailwind CSS is other framework which is gaining popularity and it is little different than the others. It is a set of utility classes so that you can create your own buttons and other stuff which really looks different than the others. They are also highly customizable.
Vanilla JavaScript

After learning HTML and CSS, the next thing that you need to learn is Vanilla Javascript. It’s very important for developers to have a good command of javascript fundamentals. You will be using a lot of javascript with server-side languages such as PHP, Python or and learning this language is much needed if you want to work with React, Angular, NodeJS, Vue or any other javascript framework or library. Below are some important topics you should cover in javascript…

JavaScript Fundamentals (variables, data types, functions, conditionals, etc)
DOM (Document object model)
JSON (Javascript Object Notation)
Fetch API (Request/Response/Ajax)
Modern JS (ES6) concepts is really important to learn if you want to move to React, Vue, Angular or other frameworks.
Some Important Tools

There are some tools that you will be using in web development. These tools will help you in debugging, boosting your productivity, managing your code, collaborating with other developers and a lot of stuff like that. Let’s discuss some of these tools.

Git (Version Control) & Github is the most popular tool that you should definitely learn in 2022. Git helps a lot in collaborating with other developers and managing your code. You also have some other options such as GitLab, Bitbucket and some other ones as well.
Learn how to use Browser Dev Tools. Whether it’s chrome or firefox, you should know how to use the different tabs such as element tab, console for javascript, network tab for request and response, application tab and other tabs for different purpose.
Most of the IDEs or text editors have the ability to add extensions or plugins that is very helpful in boosting productivity and building web apps. For example VSCode Extensions in visual studio code helps in downloading the extension such as live-server or live-saas compiler to work with React.
Emmet is another great tool that allows you to write really fast HTML and CSS which is helpful in boosting the productivity of developers.
Learn to use the javascript package manager such as NPM and Yarn. These package managers you will be using a lot if you are working with Javascript frameworks or library such as React, but for other languages (like Python or Php) you will be using the different package manager.
If you want to install NPM packages on the frontend you have to use Webpack or Parcel. If you want to create your own module or if you want to bring one javascript file to another javascript file, you can’t do that by default just with the browser so you need Webpack or Parcel to bundle it for you.
Basic Deployment

At this point, once you know what tools or technology you should learn for frontend development, you need to know how to deploy your frontend website on the internet. If you are building some tiny applications, landing pages or personal sites for small businesses there is no need to learn AWS or DevOps just because it is shiny and trendy. You will be complicating things more instead of making it simple. There are some tools and steps for deployment that you should learn in 2022.

Domain Registartion (Namecheap, Google Domains etc.)
Managed Hosting (InMotion, Hostgator, Bluehost, etc)
Static Hosting (Netlify, Github Pages)
SSL Certificate.
FTP, SFTP (File Transfer Protocol) is good for smaller applications.
SSH (Secure Shell) for advanced app.
CLI and Git.

Whatever tools, technologies trends or steps we have discussed till now is a part of frontend development. You don’t know the framework yet but you can build the website for individual & small businesses or you can build a mobile-friendly layout. You can also deploy your small application or project using the tools or technologies we have discussed so far. If you want to apply for the jobs then it would be great to learn some frontend framework such as React, Vue or Angular.

Front-End Framework and State Management

Frameworks allow you to do more advanced frontend development. Frameworks give you a lot of advantages such as reusable components, more organized UI or page interaction. It’s better for collaboration and helps in writing clean code as well. Also, learn about state management. Each framework has different ways of doing this. For 2022 below are some popular frameworks and state managers.

React: React library is the most popular to learn for web development and it’s fairly easy in comparison of other frameworks and library. There are lot of job available for React developers as well. You can use Redux and Context API with Hooks for state management.
Vue: Vue is also gaining the popularity and developers can prefer to learn Vue as well. Vue is also easiest to learn in comparison of React and Angular. VueX is the state manager built for view.
Angular: This framework is generally used in large organizations. It has pretty steep learning curve. Also it’s good to learn TypeScript with Angular. It allows you to use optional static typing and support for the features of ES2015. NGRX and Services are good state managers to learn for this framework.


Optional to Learn:

If you have the knowledge for one of the three frameworks then you also get into the Svelte which is a javascript compiler allows you to produce pure vanilla JS code and helps you to build user interface easily.
Learn about the server-side rendering. NextJS (React) and NuxtJS (Vue) is the framework that allows you to run React and Vue on the server. Both have great features such as Better SEO, File System Routing, Automatic Code Splitting, Static Exporting, CSS in JS and a lot of other features.
Static Site Generators: Gatsby (React) and Gridsome (Vue)

We have discussed all the majority of frontend development tools and technology. Now let’s talk about the language and technology to become a backend developer or full-stack developer.

Server-Side Language (Choose One)

You should have the knowledge of at least one server-side language. To choose a language in 2022 some of the options are given below…

NodeJS (Not a language but a runtime environement)
Python (Good for absolute beginners)
Java (Good for large organization)
Php (Good for freelancing)
Ruby (Less pupolar in 2022)

Note: Whatever server-side language you prefer to learn, make sure that you learn about the data structures and algorithms using that language. Data Structures and Algorithms will help you to render your data for the user and it will help you to optimize your code in web application. We especially recommend you to focus on working with Array and String (Most important). You will be working a lot with both of these.

Server-Side Framework (Choose One)

Once you learn one server-side language of your own choice, go with one of the frameworks for your language. You can choose one of the options given below…

Node.js– Express, Koa, Adonis, Feather.js, Nest.js
Python: Django, Flask,
Java: Spring MVC, Grails
PHP: Laravel, Symfony, Codeignitor, Slim
Ruby: Ruby on Rails, Sinatra
Go: Revel
Database (Choose One)

Most of the web apps need a place to store data. In some cases, certain technology or certain languages go well with certain databases. For example: in Mern stack, M stands for MongoDB and in LAMP stack M stands for MySQL but it’s totally up to you which database you want to choose for your application. We are going to discuss some popular databases for 2022.

Relational Database: RDBMS are still most popular databases. PostgreSQL, MySQL, MS SQL are stiil most preferred to use.
NoSQL: MongoDB, RethinkDB, CouchDB
Cloud Database: Firebase, Azure Could DB, AWS
Lightweight & Cache: Redis, SQLlite, NeDB

When you will be learning databases you will also learn SQL (Structured query language) for RDBMS, ORM (Object Relational Mapper) or ODM (Object Data Mapper).

GraphQL: (Optional) You can learn about the GraphQL which quite popular now a days. It’s a query language for your API. It has a simple syntax similar to JSON and it is fairly easy to implement.

Content Management

You should definitely learn about the content management system especially if you are freelancing. A CMS is used to add content to your website or application. It is great for clients to be able to update their own content.

Traditional CMS: WordPress (PHP), Drupal(PHP), Keystone (Javascript), Enduro (Javascript)
Headless CMS: (Getting popularity in 2022) Contentful,, Strapi.
Deployment & DevOps

Hosting a full-stack app or backend app is a bit more complicated than just a frontend application especially when you have databases. Make sure that you know how to use CLI for deployment. Learn about the below stuff for the deployment of your application.
In most of the companies, there is a different team working on DevOps. So it’s completely optional to have knowledge about DevOps. You can learn that if you are working on your own project.

SSH (Secure Shell)
Web Server Environment: NGINX, Apache
App Hosting: Linode, Heroku, AWS, Azure, Now.
Virtualization: Docker, Vagrant
Testing: Unit, Functional, Integration etc.
Load Balancing, Monitoring, Security.

All the above technology, tools are good enough to make you a frontend, backend or full-stack developer. Choose the right set of tools and technology as per your end goal.

10 Google Hacks to Improve Your Search Rank for Free !

Money alone can’t buy Google rank, but with a little time and strategy you can improve your position on the search engine results page (SERP) without spending a dime. Here are 10 free ways to improve your Google search rank.

Improve your website’s user experience. According to a study on ranking factors by SEMrush, the top four ranking factors are website visits, time on site, pages per session, and bounce rate. All four of those are directly related to the experience your website is providing your users, which Google recently emphasized with its Page Experience update. It’s pretty simple: If your website is easy and enjoyable to use and offers valuable information, you’ll get more visitors, who will stay longer on your site and visit more pages, and that will improve your search rank.
Write great content optimized for SEO. Having high-quality content on your website is one of the best ways to increase traffic and improve your search rank. In fact, Google itself said in a blog post on page experience that having great, relevant content on a page is more important for ranking than page experience. Make sure your content is mistake-free, keyword-rich, mobile-optimized, written to address the specific needs of your target audience, and includes valuable links to additional internal and external content.
Get more backlinks. Backlinks—links from other sites to yours—are one of the most heavily weighted Google ranking factors. Incoming links to your website content from high-authority domains show your site’s authority, bring in traffic, and improve your search ranking.
Improve your page speed. Load time is one of the key measurements in Google’s recent Core Web Vitals upgrade, so it’s a good idea to make sure your site is as fast as possible—both to improve your search rank and provide a good user experience.
Fix broken links. Having quality links on your website is one of the best ways to boost traffic and establish the authority of your site, but links that bring up a 404 error hurt both your user experience and your search rank. Use a tool like BrokenLinkCheck or Dead Link Checker to find any broken links.
Optimize your images. Optimizing your images is crucial to boosting the speed of your site and making it easier for Google to identify the images on your web pages. Make sure all your website images are compressed, have descriptive filenames, and include alt text.
Use H1 and H2 header tags. Not only do headers make your content more readable and easier to understand for humans and search engines alike, there is a strong correlation between Google search rank and the use of header tags in the body of your content. Header tags are also a great way to show the structure of your content and emphasize your key points.
Optimize for local search. More and more people are using their smartphones to search for businesses “near me.” To improve your chances of having your business show up in relevant local searches, make sure you claim your Google My Business listing, provide relevant content in Google Posts, get your business listed in local directories, and improve your online reputation with great online reviews.
Optimize for voice search. According to a study by Perficient, voice search is no longer growing, but more than 60% of people surveyed still said voice search is their preferred method of asking questions on their smartphone. Make sure those voice searches find your business by incorporating likely voice search phrases into your website content—be sure to use full sentences phrased in a natural conversational style rather than single keywords.
Aim for “position zero.” When a user asks a question in Google Search, Google sometimes pulls content from a relevant website and displays it in a special featured snippet or answer box above the #1 search result. Getting content into a featured snippet is a great way to increase traffic (snippets include a link to the page where the content came from), as well as boost the credibility and visibility of your brand. To increase your chances of having your content selected as a featured snippet by Google, think of likely searches related to your business and pepper your site with clear, authoritative answers.
