𝐈𝐧𝐭𝐞𝐫𝐧𝐚𝐥 𝐝𝐨𝐜𝐮𝐦𝐞𝐧𝐭𝐬 𝐚𝐛𝐨𝐮𝐭 𝐆𝐨𝐨𝐠𝐥𝐞'𝐬 𝐂𝐨𝐧𝐭𝐞𝐧𝐭 𝐖𝐚𝐫𝐞𝐡𝐨𝐮𝐬𝐞 𝐀𝐏𝐈 𝐡𝐚𝐯𝐞 𝐛𝐞𝐞𝐧 𝐥𝐞𝐚𝐤𝐞𝐝, giving a glimpse into how Google's search algorithms work. The leak includes information on how content, links, and user interactions are stored, but does not provide details on how scoring functions are calculated.
The leaked documents describe 2,596 modules with 14,014 attributes linked to different Google services such as YouTube, Assistant, and web documents. These modules are part of a single, massive repository, meaning all the code is kept in one place and can be accessed by any computer on the network.
𝐆𝐨𝐨𝐠𝐥𝐞'𝐬 𝐌𝐢𝐬𝐥𝐞𝐚𝐝𝐢𝐧𝐠 𝐒𝐭𝐚𝐭𝐞𝐦𝐞𝐧𝐭𝐬:
𝐃𝐨𝐦𝐚𝐢𝐧 𝐀𝐮𝐭𝐡𝐨𝐫𝐢𝐭𝐲: Despite Google's claims, the leaked documentation reveals a feature called "site authority," showing that Google does measure the overall authority of a site.
𝐂𝐥𝐢𝐜𝐤𝐬 𝐟𝐨𝐫 𝐑𝐚𝐧𝐤𝐢𝐧𝐠𝐬: Contrary to Google's public denials, systems like NavBoost use click data to influence search rankings.
𝐒𝐚𝐧𝐝𝐛𝐨𝐱: The documents mention a "hostAge" attribute used to sandbox new sites, contradicting Google's denial of a sandbox effect.
𝐂𝐡𝐫𝐨𝐦𝐞 𝐃𝐚𝐭𝐚: Despite their denials, the documentation shows that Google uses Chrome data in its ranking algorithms.
𝐀𝐫𝐜𝐡𝐢𝐭𝐞𝐜𝐭𝐮𝐫𝐞: Google's ranking system consists of multiple microservices rather than a single algorithm. Key systems include Trawler (for crawling), Alexandria (for indexing), Mustang (for ranking), and SuperRoot (for query processing).
𝐓𝐰𝐢𝐝𝐝𝐥𝐞𝐫𝐬: These are functions that adjust search results before they are shown to users. Examples include NavBoost, QualityBoost, and RealTimeBoost.
𝐒𝐄𝐎 𝐈𝐦𝐩𝐥𝐢𝐜𝐚𝐭𝐢𝐨𝐧𝐬:
𝐏𝐚𝐧𝐝𝐚 𝐀𝐥𝐠𝐨𝐫𝐢𝐭𝐡𝐦: Panda applies a scoring modifier based on user behavior and external links at various levels (domain, subdomain, subdirectory).
𝐀𝐮𝐭𝐡𝐨𝐫𝐬: Google explicitly tracks author information, highlighting the importance of authorship in rankings.
𝐃𝐞𝐦𝐨𝐭𝐢𝐨𝐧𝐬: Various penalties are applied for issues like anchor text mismatch, user dissatisfaction with search results (SERP dissatisfaction), and exact match domains.
𝐋𝐢𝐧𝐤𝐬: Links remain crucial, with metrics like sourceType indicating the value of links based on where a page is indexed.
Content: Google assesses the originality of short content and counts tokens, emphasizing the importance of placing key content early in the text.
