Validate your website to prevent rendering and accessibility problems, and to improve performance, security, and SEO.
Correct HTML ensures compatibility with assistive technologies like screen readers and voice navigation, making your site more accessible to users with disabilities. A well-structured page improves navigation, enhances usability, and helps meet legal accessibility requirements such as WCAG.
Validation highlights HTML errors that often cause unexpected behavior, making debugging more straightforward. Fixing these issues early prevents cascading problems, improves cross-browser consistency, and reduces time spent troubleshooting layout and functionality bugs.
Search engines prefer clean, well-structured HTML, making it easier to crawl and index your content. Validation prevents structural issues that could lower rankings, ensuring your site remains visible and competitive in search results.
Properly formatted HTML reduces rendering errors, leading to faster page loads and smoother interactions. Clean code ensures consistent behavior across browsers, preventing performance bottlenecks and improving the user experience.
A validated website reflects attention to detail and technical competence. Broken or invalid HTML can create layout issues and security risks, making your site appear unprofessional. Clean, well-structured code enhances trust and credibility with users.
Malformed HTML can introduce vulnerabilities that attackers exploit, such as cross-site scripting (XSS). Validation helps catch structural flaws early, reducing security risks and improving overall site stability.
