What counts as a primary source?

This directory favors original standards, official platform specifications, eligibility rules, API references, and technical documentation from the organizations responsible for them. It is a curated reference, not a list of recommended SEO tactics and definitely not a ranking-factor checklist.

Publication stage and lifecycle status mean different things. A draft can still be actively maintained. A published specification can become superseded. Likewise, a source being listed here does not establish that every search engine supports it.

“Last verified” is an editorial link review date, not a promise that every paragraph of a living document was independently audited. Check the source itself for the latest requirements. The full JSON dataset carries the editorial policy, field definitions, inclusion criteria, and known coverage gaps.

Want a version with every reference rendered as ordinary HTML and no interactive elements? There is a plain-text-friendly HTML edition, too.
