What Is Google Ranking Factors 2020 and Why It Matters for Agencies

Google ranking factors are the criteria Google's algorithm uses to determine which websites appear at the top of search results for any given query. In 2020, this concept became particularly important because Google had made significant algorithmic updates throughout the year—most notably the Core Web Vitals update announcement—that shifted which factors carried the most weight in rankings. Rather than a single formula, Google uses hundreds of signals, but certain factors consistently matter more than others: content relevance and quality, E-A-T (expertise, authoritativeness, trustworthiness), backlink quality and quantity, technical site performance, user experience metrics, and mobile-friendliness. The 2020 focus increasingly centered on how websites actually performed for real users, not just how well they were optimized for crawlers.

For SEO agencies, understanding ranking factors in 2020 was crucial because it meant shifting client strategies away from older tactics that had started losing effectiveness. Agencies that continued pushing keyword density and link quantity without quality context found themselves unable to move the needle for clients. The year forced a recalibration: agencies needed to articulate to clients why a website redesign addressing Core Web Vitals mattered as much as content creation, why E-A-T signals required more investment in author credentials and brand authority, and why backlink strategies needed to focus on relevance rather than volume. This understanding also became a competitive advantage for agencies that could explain these factors clearly to prospects—positioning themselves as modern, algorithm-aware partners rather than agencies still operating on outdated SEO playbooks.

Practically, agencies should use ranking factor knowledge to audit existing client websites systematically. Rather than assuming a ranking problem stems from content, an audit grounded in 2020 ranking factors examines page speed, Core Web Vitals metrics (Largest Contentful Paint, First Input Delay, Cumulative Layout Shift), mobile responsiveness, and content quality simultaneously. This diagnostic approach allows you to identify which factors actually need work for each specific client. When presenting findings, ranking factors become your framework for explaining recommendations—not "we need to improve your site speed" but "your Largest Contentful Paint is 4.2 seconds, which affects both user experience and rankings."

For web designers specifically, the 2020 ranking factors meant that technical performance became non-negotiable rather than optional. A beautiful design that loads slowly or shifts during user interaction actively harms rankings. Designers can use ranking factor knowledge to justify performance-focused design decisions to clients who might otherwise prioritize flashy visuals, and to advocate for development approaches that prioritize user experience metrics. When a client pushes back on removing an auto-playing video or infinite scroll, you now have algorithmic legitimacy behind performance recommendations.
