HTML is the foundational language of the web. Semantic HTML markup on your webpages can help machine systems better understand your content and its value.
While most website visitors won’t know whether your HTML validates or not. The systems and tools they rely on absolutely do.
That includes:
• Search engine crawlers like Googlebot
• Assistive technologies like screen readers
• Web browsers on different devices and screen sizes
• Automated accessibility and performance audits
• Future developers who need to work on your site
When your code is full of errors, missing tags, broken structure, invalid nesting, or outdated syntax, it’s like asking those systems to read a book with missing pages, scrambled sentences, and blank chapters.
It’s for this reason that professional web developers validate their code, however 98% of websites don’t have valid code.
