Google Warehouse API (Documentation Leak)

Internal Google documentation leak (2024) revealing metrics used to evaluate websites, including Site Focus Score and Site Radius. Confirmed that Google measures topical coherence of domains through an embedding centroid and distances from it.

The leak is treated as breakthrough evidence of semantic site coherence importance. These metrics can be calculated independently using embeddings in Google Colab (practical analysis). The leak also revealed that Google classifies domains during Core Updates based on three clusters: documents, phrases, and historical data.

In practice, treat the Google Warehouse API leak as a roadmap — Site Focus Score and Site Radius are metrics Google actually uses. Calculate them for your domain and competitors to see where you stand. A garden furniture store example confirms that improving these metrics translates to real ranking gains.
