Google Content Warehouse API leak
The May 2024 publication of thousands of internal Google Search API documentation attributes, which named ranking-related features not previously disclosed.
In full
The documents were briefly public in a code repository and described data structures and attribute names — including references to site authority, click-based signals and content classifiers — without describing weights or whether each was used in live ranking. Google confirmed the documents were genuine but cautioned against drawing conclusions about ranking from out-of-context, potentially outdated field names. The leak is best treated as vocabulary and hypothesis material, never as a specification.
Example
The presence of a `siteAuthority` attribute prompted debate, though nothing in the documents established how or whether it is used in ranking.
