A ranking factor is any specific element or signal that a search engine’s algorithm considers when determining how to rank a webpage for a given query — examples include backlink quality, content relevance, page speed, and mobile-friendliness.
Google uses hundreds of individual ranking factors combined together, and has never published a definitive, complete list, meaning SEO practitioners rely on a combination of Google’s official statements, industry testing, and correlation studies to prioritize their efforts.
Because ranking factors and their relative weight evolve continuously through algorithm updates, staying current on genuine, confirmed signals rather than outdated or speculative folklore is essential for effective strategy.
We prioritize confirmed, high-impact ranking factors across all of our SEO services.
