WCAG (Web Content Accessibility Guidelines) is the internationally recognized standard defining specific criteria for making web content accessible to people with disabilities, published and maintained by the World Wide Web Consortium (W3C).
WCAG compliance is often a legal requirement in many jurisdictions for certain types of businesses and organizations, making it both a genuine usability consideration and a compliance necessity in many cases.
While WCAG compliance isn’t a direct Google ranking factor, many of its specific criteria, such as proper alt text and semantic structure, directly overlap with established SEO best practices.
We consider WCAG guidelines within our On-Page SEO service where relevant.
