Ranking Factors: How Google Determines Order
Ranking factors are the signals and criteria that Google uses to determine the order of search results for a specific search query. Google uses over 200 known factors in its ranking algorithm.
Key Takeaways
- ✓Google does not name a fixed number of ranking factors, but evaluates 'many factors and signals' across hundreds of billions of pages; the popular '200 factors' is a myth, not a confirmed figure.
- ✓Relevance and content quality, backlinks/authority, and E-E-A-T are considered the strongest signal groups; Core Web Vitals, Mobile-First, and HTTPS act more as supporting factors or tie-breakers.
- ✓Ranking factor and correlation must be distinguished: what is reliable is what Google confirms or the 2024 API leak proves, not every correlation from an SEO study.
- ✓The Helpful Content System has been part of core ranking since March 2024; helpfulness is no longer a separate filter but integrated.
- ✓AI Overviews reduce CTR for position 1 by around 58 percent according to international analysis, yet AI answers draw from top rankings, making good placements more important, not less.
- ✓GEO complements SEO: citable content with statistics and sources increases visibility in generative answers by up to 40 percent according to a Princeton study.
- ✓B2B prioritization in the DACH region: first technical foundation and search intent (quick wins), then content quality and E-E-A-T, long-term authority and backlinks.
Google uses hundreds of signals to determine the ranking of search results. Understanding these ranking factors is key to successful SEO.
The most important ranking factor categories
Content relevance is the most fundamental factor. Google evaluates how well a page's content matches the search query. This involves not just keywords, but semantic relevance, thematic depth, and satisfaction of search intent.
Backlinks and authority signals form the second pillar. Every link from an external website is a vote of confidence. The quality and thematic relevance of the linking website is more important than sheer quantity. In 2026, unlinked brand mentions are gaining importance.
User experience is the third pillar. Core Web Vitals (LCP, INP, CLS), mobile-friendliness, and page speed influence ranking. The impact is estimated at 10-15 percent and primarily acts as a tie-breaker between pages with similar content.
E-E-A-T as an overarching framework
E-E-A-T stands for Experience, Expertise, Authoritativeness, and Trustworthiness. It's not a single ranking factor, but an overarching quality framework that applies to virtually all competitive queries since the December 2025 Core Update.
Experience means demonstrable first-hand experience. Expertise is shown through technical depth and precision. Authoritativeness is built through external signals like citations and industry recognition. Trustworthiness is based on transparency, source citations, and consistent information quality.
The Google API Leak 2024
In May 2024, internal Google API documents became public. These confirmed several suspected ranking signals: Google uses click data and Chrome browser data as ranking signals. Brand authority plays a central role. Document freshness is weighted more heavily than publicly communicated.
Ranking factors for AI visibility
For visibility in AI-generated answers, different factors partially apply. Brand mentions correlate with 0.664 to AI visibility, while traditional backlinks only correlate with 0.218. Source citations, statistics, and expert quotes increase AI citation probability by 30-40 percent.
