Ranking Factors
The signals the algorithm weighs when ordering pages, numbering in the hundreds.
Analogy Mental model
A university admissions system. Exam scores matter, and so do the physical, the volunteering and the conduct record. Nobody is admitted on one number alone.
In practice What you actually do
Do not try to optimise two hundred signals. The concentration is well established: content that answers the query, links that indicate trust, and a page experience that does not punish the visitor. Those three absorb most of the variance.
Where people get burned Pitfalls
Google has never published the full list or the weights. Every percentage breakdown circulating online is a vendor's inference, and treating it as data is how teams spend a quarter optimising a number that was never real.
