Google seemingly leaked a treasure trove of technical search algorithm details by accident and now SEO people are getting real aggro
Around 2,500 technical documents detailing the nuts and bolts of Google's ranking algorithms have apparently leaked. If the documents are real, it's an unprecedented look into the workings of the utterly dominant internet search engine. And one hell of an error, because it is stated that Google itself published the documents to GitHub before taking them down. But nothing published to the web disappears overnight, and the documents have been kept for posterity elsewhere.
This leak provides an interesting opportunity to compare the reality of how Google ranks its search results with the various claims the company has made about what has hitherto been largely a mysterious black box. The inner workings of Google Search have long been speculated upon but never really known outside of the company itself—or indeed inside the company by most Google employees.
The documents were shared with long-time SEO specialist Rand Fishkin by Erfan Azimi, an SEO advisor at EA Eagle Digital. Azimi says he shared the documents in the hope that they would reveal the «lies» propagated by Google in relation to its search platform.
That is obviously a very, very bold claim. Frankly, the documentation is incredibly dense and technical and covers a huge array of topics and systems. In really broad brush terms, it covers the type and character of data Google collects and uses, which sites Google elevates for sensitive topics like elections, how Google handles small websites, and much, much more.
There are various areas where it's claimed that analysis of the documents throws up clear contradictions with Google's claims. For instance, in 2016 Google Search engineer Paul Haahr said that «using clicks directly in rankings would be a mistake.»
But it's claimed the documents prove that Google uses a system known as NavBoost that directly incorporates various click count metrics into the page rankings and search results.
Other areas highlighted in contradiction to previous Google claims include the
