Frequently asked questions
Why does page speed matter for SEO?
Google uses page speed (Core Web Vitals) as a ranking factor, and slower pages also see higher visitor bounce rates - faster pages tend to both rank better and convert better.
What usually causes a slow page speed score?
Large unoptimized images, too many render-blocking scripts/stylesheets, lack of browser caching, and slow server response time are the most common culprits.
Do mobile and desktop scores differ?
Yes - mobile devices typically have less processing power and slower networks, so mobile scores are often lower than desktop scores for the same page; Google primarily uses mobile performance for ranking.
