Google’s Clarification on Ranking Signals and Systems
In a series of tweets, Danny Sullivan, Google’s Search Liaison, clarified that page experience, mobile-friendliness, page speed, and secure site factors are ranking “signals” and not ranking “systems.”

This distinction was made after Google removed several ranking systems from its help documentation, including page experience, mobile-friendly ranking, page speed, and secure sites systems.
“Taking them off didn’t mean we no longer consider aspects of page experience. It just meant these weren’t ranking systems but instead signals used by other systems.”
– Danny Sullivan
The key takeaway from Sullivan’s explanation is that “Google’s core ranking systems look to reward content that provides a good page experience.” This means that page experience is a ranking “signal,” not a ranking “system,” and is considered a “concept.”
Ranking Signals vs. Ranking Systems:
Understanding the Difference |
---|
Ranking Signals |
Individual factors |
Inform ranking systems |
Examples: Page experience, mobile-friendliness, page speed, secure site factors |
Ranking Systems |
Algorithms/processes |
Use multiple signals |
Examples: Core ranking systems |
Ranking signals are individual factors that Google’s algorithms consider when determining the relevance and quality of a web page. These signals, such as page experience, mobile-friendliness, page speed, and secure site factors, inform Google’s core ranking systems.
Ranking systems are the algorithms or processes that Google uses to analyze and rank web pages based on various signals. These systems typically make use of multiple signals to deliver the most relevant and high-quality search results to users.
