W3C is the World Wide Web Consortium and was founded by the creator of the WWW, Tim Berners-Lee. This web standards body creates coding specifications for web standards around the world and provides a validation service to ensure that HTML or other code is valid and error-free.
The W3C has created a set of standards that explain what the code on a web page should look like and, when adhered to, provide a better user experience.
Making sure that a web page or website is valid is one of the most important things that can be done to achieve cross-browser and cross-platform compatibility as well as provide an online experience for users. Invalid code can lead to crashes, rendering errors and long processing or loading times.
In short, code that contains errors and does not do what it is supposed to do in the major browsers will negatively affect SEO and user experience.
how does W3C validation work and how does it affect SEO?
Web standards are important because they provide web developers with a standard set of rules for writing code. By using the same protocols, developers can create web pages and sites that are easier to maintain and the code will also be easier to update.
This is especially important when working in a team or when working with web pages, where many times, more than one person is working.
On the other hand, when it comes to SEO, a validated code is always better than one that is poorly written. John Mueller, Google’s SEO expert, pointed out that Google does not care how a code is written, so it will not get a better position in the SERP if the code is better or worse written.
However, it does have indirect effects on SEO. For example, validating the code means having to remove all the excess, leaving a “leaner” and more compact code, which is better understood. It also reduces rendering times, which translates into faster loads and also better processing power. In this way, we are helping to improve the Core Web Vitals.
