How strongly do Core Web Vitals affect Google rankings?

Core Web Vitals are a confirmed ranking factor, but one among many. Google has emphasized that content relevance remains the strongest signal. In practice, Core Web Vitals primarily act as a tie-breaker: when two pages offer similarly relevant content, Google favors the faster one. For highly competitive keywords, this difference can determine whether you rank at position 3 or position 8. Our experience shows that websites typically gain two to five positions on relevant search terms following comprehensive performance optimization.
