A complete breakdown of Google’s 200 ranking factors every SEO expert should know. Viet SEO prioritizes them by importance and explains each in simple terms — helping you focus on what really matters.
Introduction: Why Are Google’s 200 Ranking Factors Important for SEO?
Google is the most popular search engine in the world — and the “gatekeeper” of billions of search queries every day. According to VietSEO agency, to decide which pages show up first when a user types in a query, Google relies on more than 200 different ranking factors in its algorithm.
Understanding these ranking signals is a foundational step in any effective SEO Google strategy. But do you really need to optimize for all 200? Not necessarily. Some factors have a major impact on search performance, while others act more as supporting signals.
The goal of this guide is to help you understand each factor — from the most critical to the least impactful — so you can focus on what truly matters, save time, and maximize your SEO Google efforts for long-term success.
