Official Search Engine Documentation: An SEO Reference Hub
SEO advice online varies wildly in quality. This hub links straight to the primary documentation published by search engines and standards bodies, so you can check claims at the source.
When an SEO claim matters, check it against the people who run the search engine. These are the primary sources worth bookmarking.
Search engine guidelines
- Google Search Central documentation covers crawling, indexing, ranking systems, structured data and spam policies.
- Bing Webmaster Guidelines explain how Bing finds and ranks content.
Structured data
- Schema.org is the shared vocabulary for structured data used by the major search engines.
- Google's Rich Results Test checks whether a page's markup is eligible for rich results. Our BlogPosting schema tutorial walks through an implementation.
Page experience and performance
- Web Vitals on web.dev explains Core Web Vitals and how to measure and improve them.
- PageSpeed Insights reports field and lab performance data for any URL.
Is it you, or is it Google?
- The Google Search Status Dashboard lists ranking updates and known crawling or indexing incidents. Check it before assuming a traffic drop is your fault.
