Content Warehouse API
Google's internal API, leaked in 2024, that exposed documented ranking attributes including site-level topical authority variables.
The Google Content Warehouse API is an internal system whose documentation was inadvertently leaked in 2024, revealing specific attributes and variables Google uses in its ranking systems. The leak confirmed the existence of site-level topical authority metrics including site2vecEmbeddingEncoded, siteFocusScore, and siteRadius — providing the first documented evidence that Google quantifies topical authority as a measurable, site-level signal rather than a theoretical SEO concept.
