Validated code is important for successful SEO because it helps ensure that search engines can easily crawl and understand your website’s content. When a search engine crawls your website, it reads the HTML code to determine the structure and content of your website. If the code is not valid, it can make it difficult for search engines to properly index and understand your website’s content.

Validating your code involves checking your website’s HTML code to ensure that it follows the correct syntax and does not contain any errors. This can be done using various online tools, such as the W3C Markup Validation Service.

By validating your code, you can ensure that search engines can easily crawl and understand your website’s content, which can help improve your website’s ranking in search engine results pages (SERPs). Valid code can also improve your website’s loading speed, which is an important factor in user experience and can affect your website’s ranking in search engines.

In addition, valid code can also help ensure that your website is accessible to users with disabilities, which is an important consideration for SEO and user experience. By providing a website that is accessible to all users, you can improve your website’s engagement and attract more traffic, which can ultimately lead to higher search engine rankings and increased exposure for your business.

Overall, validating your code is an important SEO best practice that can help improve your website’s visibility and ranking in search engines.
