The W3C is the World Wide Web Consortium and was founded by the creator of the World Wide Web, Tim Berners-Lee. It creates coding specifications for web standards worldwide and also offers a validator service to ensure that your HTML is valid and error-free.

Making sure that your page validates is an important thing in order to achieve cross-browser and cross-platform compatibility and provide an accessible online experience to all. Unsure about how to deal with it? Do contact our SEO agency in Kochi.

Invalid code results in glitches, rendering errors, and long processing or loading times, meaning, if your code doesn’t do what it was intended to do across all major web browsers, this can negatively impact user experience and SEO.


A look into how W3C Validation Works and Supports SEO

Web standards are essential as they give web developers a standard set of rules for writing code. It will be much easier for you to maintain and update the code in the future if all code used by your company is created using the same protocols.

This is important when working with other people’s code because if your pages adhere to web standards, they will validate correctly against W3C validation tools.

When web standards are used as the basis for your code creation, you can be assured that your code is user-friendly with built-in accessibility.

With SEO, validated code is always better than poorly written code.

According to John Mueller, Google doesn’t care how your code is written, meaning a W3C validation error won’t cause your rankings to drop.

And you won’t rank better with validated code, either. But there are indirect SEO benefits to well-formatted markup:

Eliminates Code Bloat:

Validating code helps to avoid code bloat. Validated code is generally leaner, better, and more compact than its counterpart.

Faster Rendering Times:

As the browser needs less processing, and we know that page speed is a ranking factor, you’ll have lesser rendering times.

Indirect Contributions to Core Web Vitals Scores:

When coding standards are paid attention to, such as adding the width and height attribute to your images, it eliminates steps that the browser must take to render the page. Faster rendering times contribute to your Core Web Vitals scores, improving these important metrics overall.

How does W3C Validation Work?

The W3C validator is this author’s validator of choice that makes sure that your code validates across a wide variety of platforms and systems.

The W3C validator is free to use and with it, it’s possible to validate your pages by page URL, file upload, and Direct Input.

Validate Your Pages by URL:

This is simple and can be done by just copying and pasting the URL into the Address field, and clicking on the check button to validate your code.

Validate Your Pages by File Upload:

Through this process, you will upload the HTML files of your choice one file at a time. But if you’re using Internet Explorer or certain versions of Windows XP, this option may not work for you.

Validate Your Pages by Direct Input:

Here, all you have to do is copy and paste the code you want to validate into the editor, and the W3C validator will do the rest.


Common Validation Errors That Can Occur

It is essential to be aware of the most common validation errors as you go through the validation process.

Hence, if your page does not validate, you will know exactly where to start looking for possible problems.

Some of the most common validation errors include:

Type Mismatch:

This happens when your code is trying to make one kind of data object appear like another data object, you run the risk of getting this message. This error signals that some kind of coding mistake has been made and the solution would be to figure out exactly where that mistake was made and fix it so that the code validates successfully.

Parse Error:

This error indicates that there was a mistake in the coding somewhere. But you can’t know where that mistake is. So, if this happens, you will have to do some serious sleuthing to find where your code went wrong.

Syntax Errors:

These types of errors involve careless mistakes in coding syntax. For instance, either the syntax is typed incorrectly, or its context is incorrect. Either way, these errors will show up in the W3C validator.

Final Words

Sometimes validation doesn’t happen as planned and according to all standards.

But there is more than one way to accomplish the same goal. Though validation, on the whole, can help you immensely, it is not always going to be 100% complete.

Hence it’s important to familiarize yourself by coding with the validator as much as you can.

Some adaptation will be required and it takes experience to achieve the best possible cross-platform compatibility while also remaining compliant with today’s browsers.

The ultimate goal should be to improve accessibility and achieve compatibility with all browsers, operating systems, and devices.
