Core Web Vitals Impact Study: Does Page Experience Affect Rankings?

Multiple studies examined the ranking impact of Core Web Vitals following Google's Page Experience update. The collective research provides data on whether meeting CWV thresholds delivers meaningful ranking benefits.

Correlation vs Causation Challenge

Studies found positive correlation between good CWV scores and rankings, but establishing causation proved difficult. Sites with good CWV tend to be well-maintained overall, potentially explaining correlations without CWV being a direct ranking factor. The relationship is likely bidirectional: better sites rank higher AND have better CWV.

Limited Direct Impact

Most research concluded that CWV provides a tiebreaker signal rather than a major ranking factor. When other factors are equal, better page experience may provide an edge. However, content relevance and authority signals continue to dominate ranking decisions. Sites with poor CWV but excellent content frequently outrank CWV-optimized competitors.

Industry Variations

Impact varied by industry and query type. E-commerce and local searches showed more CWV correlation, potentially because user experience affects conversion signals Google might track. Information queries showed less CWV impact, with content quality remaining dominant.

Strategic Prioritization

The research suggests CWV optimization matters most when competing against similar-quality content or for competitive commercial queries. For most sites, investments in content quality and authority building deliver better ROI than pursuing perfect CWV scores.
