What is the Google algorithm?
The Google algorithm is the complex system of ranking systems that decides which pages appear for each query. It evaluates hundreds of signals — relevance, content quality, links, user experience, freshness and more — and is constantly refined through named and unconfirmed updates.
Why the algorithm matters
Every SEO strategy is an attempt to satisfy what the algorithm rewards: genuinely helpful content, strong authority signals and a good user experience. Algorithm updates can shift rankings dramatically, which is why sustainable SEO focuses on fundamentals rather than tricks.
Major algorithm families
- Content quality: Panda, Helpful Content, E-E-A-T signals.
- Links: Penguin, SpamBrain, link spam updates.
- Understanding: Hummingbird, RankBrain, BERT, MUM.
- Experience: Page Experience, Core Web Vitals.
Algorithms and GEO
Google’s AI systems increasingly power both ranking and answers. The same signals that win rankings — trust, authority, clarity — determine whether AI Overviews cite you.
