What does Google say about SEO? /
Web performance has become an official ranking factor in Google's algorithm, particularly since the introduction of Core Web Vitals in 2020. This category compiles all official Google statements regarding loading speed optimization, performance metrics, and their impact on organic search rankings. SEO professionals will find Google's positions on key indicators such as Largest Contentful Paint (LCP), Cumulative Layout Shift (CLS), First Input Delay (FID), and Interaction to Next Paint (INP). Google regularly communicates about the importance of loading times, Time to First Byte (TTFB), cache optimization, and techniques like lazy loading. These official declarations help understand how Google truly measures user experience, which performance thresholds to prioritize, and how PageSpeed Insights integrates into a site's overall evaluation. For search practitioners, following Google's official recommendations on web performance is crucial to maintain or improve search rankings while delivering an optimal user experience that enhances conversion rates and visitor retention. Understanding Google's evolving stance on speed metrics enables webmasters to align technical optimizations with actual ranking signals rather than assumptions or outdated practices.
