In May 2024, thousands of pages of Google’s internal API documentation were leaked publicly. The SEO community spent months analyzing what the documents revealed about Google’s ranking systems. Combined with two years of algorithm updates and observations since, we now have a clearer picture of what Google is actually measuring β and several things that were confirmed differed significantly from Google’s public statements.
What the 2024 Leak Confirmed
Click data matters. Google’s internal documentation showed systems measuring click-through rates, time on page (“long clicks” vs. “short clicks”), and user engagement signals at both the page and site level. Google had consistently denied using click data as a ranking signal. The leaked documents showed these metrics being tracked and feeding into ranking systems β whether as primary signals or calibration tools for other signals remains debated, but their presence in the system is confirmed.
Chrome data is used. Data from Chrome browsers appears in Google’s ranking systems. This includes site visit data across users, which contributes to authority signals. The implication: brand recognition and direct traffic (which Chrome data can capture) are inputs into ranking, not just outputs of ranking.
Author and entity entities are tracked. Google’s systems maintain “Author Entities” β data structures tracking individual authors and their credibility across the web. This is the mechanical implementation of author E-E-A-T signals. Authors who are frequently cited, linked to, and discussed across authoritative sources have stronger author entity profiles.
What’s Mattering More in 2026
Topical Authority
Google’s “Site Authority” concept β the idea that a site is recognized as an authority within a specific topic domain β has become more influential. Sites that demonstrate comprehensive, deep expertise within a defined subject area consistently outperform generalist sites on topic-specific queries, even when individual pages are similar in quality. The topic cluster strategy is the primary way to build topical authority signals.
Helpfulness and Original Value
Google’s Helpful Content system has become more sophisticated. It’s increasingly effective at distinguishing content that provides genuine value β original research, expert analysis, first-hand experience β from content that repackages existing information. The penalty for large-scale AI-generated content without genuine value has become more consistent and more severe.
Brand Signals
Brand-related signals β branded search volume, direct traffic, consistent brand mentions across the web β have become stronger ranking inputs. Google is incentivized to surface brands that users actively seek out, because those brands signal real-world authority and user satisfaction. Brand-building is no longer separate from SEO strategy.
What’s Mattering Less
Exact Match Anchor Text From External Links
Manipulative link building with exact-match anchor text has been devalued. Google’s Penguin system (now running in real-time) catches unnatural anchor text profiles and discounts or penalizes the links. Natural, branded, or partially-matching anchor text from genuinely earned links remains valuable.
Keyword Density
Google’s NLP understanding of content has advanced to the point where keyword density is essentially irrelevant. Pages rank for thousands of semantic variants without explicitly using those phrases. Writing naturally and covering topics comprehensively matters; counting keyword appearances does not.
Thin Pages With Some Backlinks
The combination of the Helpful Content system and improved quality evaluation has made it harder for thin pages with a few backlinks to maintain rankings they’ve historically held. Quality of content and quality of linking domain now need to both be present for sustainable rankings.
The Stable Core
Some ranking factors have been relatively consistent through all the changes:
- Quality and relevance of backlinks β still the strongest authority signal
- Page experience (Core Web Vitals, mobile usability) β confirmed ranking signal
- Content relevance and comprehensiveness β still the foundation of ranking for any query
- HTTPS β confirmed signal, though most sites meet this baseline now
