A major incident occurred when internal documents related to Google’s Content Warehouse API were inadvertently made public. This leak disclosed extensive information about Google’s internal operations, particularly those connected to the now-defunct Document AI Warehouse. This is the biggest Google SEO leak in history, providing detailed insight into the inner workings of Google’s search engine algorithm. Many of the details that were once considered rumors are now confirmed truths.

Scope of the Exposure

The leaked data revealed a broad array of elements, including ranking factors, user interactions, content storage, and links. Notably, the leak did not include any scoring functions.


Ranking Factors and Features

Extensive Feature Set

The API documentation revealed a vast feature set, consisting of 2,596 modules and 14,014 attributes. These attributes span across several systems, such as YouTube, Assistant, Books, and web documents. While many of these features are linked to ranking factors, not all are directly involved in the ranking process.

Internal Systems and Modules

Complex Infrastructure

Google’s infrastructure is highly sophisticated, functioning on a monolithic repository with shared environments. Key modules like Trawler (responsible for crawling), Alexandria (for indexing), and Mustang (for scoring) are integral to the search process.


Twiddlers are re-ranking functions that adjust information retrieval scores or alter document rankings after the primary algorithm has run, adding another layer of complexity to Google’s search engine operations.

Misleading Public Statements from Google

Domain Authority

Despite Google’s public denials, the leak uncovered the existence of a “siteAuthority” feature within its internal systems, suggesting a form of domain authority. For more on this, you can read this detailed article from Moz.

Clicks in Rankings

Internal systems like NavBoost use click-driven measures to influence rankings, contradicting Google’s public statements that clicks are not directly used in ranking. Learn more about this topic on Search Engine Journal.


An attribute called “hostAge” is used to sandbox new spam, contrary to Google’s public denials about the existence of a sandbox. Having launched over 500 websites, we have seen the effects of the sandbox numerous times. This leak confirms that our strategies to overcome its effects were justified.

Chrome Data

The leaked documents revealed that Chrome data is indeed utilized in Google’s ranking systems, despite public denials. Given Google’s access to user data through its browser, this should not come as a surprise. More information on this can be found on Search Engine Land.
