But the disclosure was not a complete ranking formula or Google’s source code. The approximately 2,500 pages described internal systems, APIs and data fields; analysts then inferred what some names might mean. Google cautioned that the material was incomplete, potentially outdated and easy to misread, so claims that it definitively exposed “algorithm secrets” go beyond the evidence.
What happened in May 2024?
In late May 2024, technical material associated with Google Search appeared to have been made available through a public GitHub repository before access was removed or restricted. Contemporary coverage described roughly 2,500 pages or documents, depending on how the material was counted, and references to thousands of internal attributes, modules and data fields.
SEO consultant Rand Fishkin published an early analysis after receiving the material from Erfan Azimi. Fishkin and other analysts argued that some terminology appeared to complicate Google’s public explanations of Search. The original contemporary report is available from Tech Times, which dates the coverage to May 29–30, 2024; its author archive is at Tech Times’ archive.
What did Google confirm?
Google reportedly confirmed to The Verge, as relayed by the Tech Times report, that the documentation was genuine. The company also warned that it was out of context, incomplete and potentially outdated.

#1 Best Overall
That confirmation establishes authenticity—not the interpretation of every field. It does not confirm that all documented features were live ranking signals, that every analyst claim was correct, or that the material describes Google Search as it operates in 2026. It also does not establish that Google intentionally lied about Search.
What exactly was leaked?
This was internal technical documentation, not one conventional “algorithm document.” A field in such documentation might represent any of the following:
Rank #2
- an API field or stored attribute;
- a classifier used to label content or sites;
- a logging or measurement mechanism;
- an experimental, deprecated or historical feature;
- a signal used for retrieval, training, evaluation, personalization or spam detection; or
- an input to one ranking stage rather than a universal ranking factor.
Coverage cited about 14,000 Search-related or “ranking” features, but that figure should be treated as a reported count, not a definitive list of 14,000 active ranking factors. The documents did not provide production weights, thresholds, feature interactions or an executable recipe for ordering results.
The most discussed fields and systems
NavBoost and user interactions
Analysts focused on references to NavBoost and interpreted them as evidence that user-interaction or click data can influence some Search systems. The documentation’s existence does not prove that raw click-through rate universally ranks pages.
Interactions can be noisy, query-dependent and vulnerable to manipulation. They might support training, query interpretation, result evaluation or a particular ranking stage. The leak alone does not establish their weighting, geographic scope, causality or anti-spam controls.
Homepage and site prominence
A field named homepagePagerankNs drew attention because analysts interpreted it as a possible measure of homepage prominence that could affect visibility elsewhere on a site. A suggestive field name is not a public definition. It does not prove that Google uses one sitewide authority score in the way third-party SEO tools sometimes present authority.
Small and personal sites
Coverage also discussed smallPersonalSite. A classifier with that name could support experimentation, diversification, evaluation, personalization or a narrowly defined adjustment; it does not demonstrate that Google systematically demotes every small or personal website.
Authors and sensitive topics
Reported fields relating to authors, news, elections, COVID-19 and authority classifications suggest that Search maintains specialized systems for sensitive or high-impact information. They do not prove that one author or “authority” score decides whether content ranks, nor that the same logic applies across Web, News, local, image or video results.
Does the leak prove Google lied?
Some commentators said the material appeared to conflict with public statements about clicks, sitewide authority, author information and small websites. That is an interpretation, not a fact independently established by the leak.
A public statement may address whether a metric is a direct ranking input, while an internal field supports training, evaluation or another Search subsystem. The documents may therefore complicate public explanations without proving intentional deception. The most accurate description is that they exposed apparent tensions between public wording and internal terminology.
Why the documents are difficult to interpret
- Field names are clues, not definitions. Names such as
smallPersonalSiteorisElectionAuthoritydo not explain thresholds, scope or effect. - Stored data is not necessarily causal. A system can collect a metric without using it directly to rank results.
- Status matters. A feature may be live, experimental, deprecated or historical.
- Scope matters. A field may apply to a page, site, query, user, language, country or document cluster—or only to one Search vertical.
- Weights and interactions were missing. Even a real production feature cannot be translated into an SEO tactic without knowing its inputs, weighting and position in the pipeline.
- Google Search is many systems. Crawling, indexing, retrieval, ranking, spam prevention, localization, personalization and experimentation do not form one simple formula.
What publishers and SEOs should do
- Do not redesign a site around a suspected leaked field or assume that increasing click-through rate guarantees higher rankings.
- Continue improving useful, original content, crawlability, performance, accessibility, appropriate structured data and overall user experience.
- Use Google Search Console to monitor impressions, clicks, indexing and technical issues; its reports are evidence about your site, not a disclosure of Google’s internal weights.
- Test substantial changes with controlled comparisons where possible, and treat third-party authority scores, rank trackers and crawler findings as directional proxies rather than Google’s own measurements.
- Be especially cautious with claims that the leak proves Google favors large sites, penalizes personal sites, ranks pages directly by clicks or uses author expertise as a universal factor.
What remains unknown
- Which documented features were active when the material surfaced.
- Which were experimental, deprecated or limited to a particular product or geography.
- Their production weights, thresholds and interactions.
- Whether Google changed the systems after the 2024 exposure.
- How much of modern Search—including newer AI-driven experiences—was covered.
- Whether any particular field represented ranking, measurement, training, evaluation or spam prevention.
Bottom line
The 2024 disclosure was a genuine leak of Google Search-related documentation, and Google reportedly confirmed its authenticity. It offered an unusual view of internal vocabulary and architecture, including terms analysts associated with interactions, site prominence and specialized classifications. It did not reveal a complete algorithm, prove that every field affected rankings, or provide a reliable “secret factor” playbook. Treat it as evidence that Search is complex and multi-stage—not as a guaranteed formula for changing your traffic.
