Algorithm
A search algorithm is a complex set of rules and calculations a search engine uses to rank web pages in response to a user query.
Definition
Search algorithms are the brains of the operation. Google's algorithm is not a single piece of code but a system of thousands of sub-algorithms and machine learning models that together determine which pages rank for which queries. These systems evaluate relevance, authority, freshness, location, device, and hundreds of other signals.
The Black Box Reality
No one outside Google knows exactly how the algorithm weights every signal. Google publishes guidelines but does not reveal proprietary ranking logic. Anyone claiming to know the 'exact ranking factors' is selling something. The smart approach is to focus on broadly agreed quality signals and let the algorithm work.
Note

Note
People often speak of 'the algorithm' as if it were static. It is not. Google deploys multiple updates daily. The algorithm you optimized for yesterday may not be the one ranking today.
