# Google API leak

Category: [Google Updates & Algorithms](https://seo-geo-glossary.com/en/glossary/category/google-updates-algorithms/) › [Historical updates & events](https://seo-geo-glossary.com/en/glossary/category/google-updates-algorithms/historical-updates/) · Also known as: Google search leak 2024, Content Warehouse API leak · Historical

**The Google API leak is the 2024 publication of internal documentation for Google Search's Content Warehouse API. The material contains over 2,500 pages and 14,014 attributes. It describes data and modules, but not how strongly they affect rankings. The leak is a closed 2024 event. For what counts in ranking today, Google's own documentation and the findings of the court in the US antitrust case remain the reliable sources.**

## What happened?

According to SparkToro, the documentation was uploaded to a public GitHub repository on March 27, 2024 and stayed accessible until May 7, 2024. Rand Fishkin of SparkToro received it from an anonymous source and published his findings in 2024. He reports that former Google employees who reviewed parts of it considered it legitimate, and that Mike King, founder of iPullRank, who analyzed it, also considers it legitimate.

## What does it show?

The files read like an internal inventory of data elements available to Search engineers. They mention, for example, NavBoost together with click data. SparkToro states that the documents do not show the weight of individual elements in ranking and do not prove which elements are in use. Some may be old, experimental or switched off.

## How should the leak be read?

As a source of terms and data structures. Claims such as "confirmed ranking factors" go beyond what the documents say.
