Draft:Google Search Algorithm Leak (May 2024)

In May 2024, a significant leak of internal Google documents occurred, providing unprecedented insight into the search engine's ranking factors and algorithmic processes. The leak, consisting of over 2,500 pages of documentation, was first disclosed by Erfan Azimi, CEO of EA Eagle Digital, and subsequently shared with Rand Fishkin, founder of SparkToro.

Contents of the Leak
The leaked documents include comprehensive details on over 14,000 API attributes and modules related to Google’s search engine. Key revelations from the documents include:

Click Data and User Signals
Contrary to Google's public statements, the documents reveal that user clicks and other click-related metrics significantly influence search rankings. The NavBoost system, in place since 2005, employs click data to adjust rankings, contradicting Google's previous denials about the impact of clicks on search results​.

Site Authority
The documents mention a "siteAuthority" score, indicating that Google does measure site-wide authority. This contradicts Google’s earlier claims that it does not use a site authority score in its ranking algorithm​ (Enterprise Technology News and Analysis)​.

Authorship and Content Quality
Google tracks author information and uses it to assess content quality. The freshness of content, relevance to the core topic of a website, and alignment between page titles and content are all significant ranking factors. Additionally, Google evaluates the average weighted font size of terms within documents​.

Chrome Data
Data from Google Chrome, identified by the "ChromeInTotal" module, is used as a quality signal. This indicates that the pages viewed through Chrome play a role in determining their quality and ranking in search results​.

Miscellaneous Factors
Other notable factors revealed include the importance of link diversity, content originality, and various algorithmic demotions such as anchor mismatch, search engine results page (SERP) dissatisfaction, and exact match domains.

Implications and Reactions
The leak has significant implications for SEO practices, exposing previously undisclosed ranking factors and contradicting many of Google's public statements. SEO experts and digital marketers are re-evaluating strategies based on the newfound information. Google has responded by cautioning against making assumptions based on the leaked documents, suggesting that they may lack context or be outdated​

This leak, being one of the most substantial in the history of Google's search division, highlights the ongoing tension between transparency and the proprietary nature of search engine operations.
