Core Web Vitals are the three key metrics Google uses to measure page user experience: LCP (Largest Contentful Paint) — how long it takes for the largest visible element to load; CLS (Cumulative Layout Shift) — how much content shifts around as the page loads; and TBT (Total Blocking Time) — how quickly the page responds to user interaction. Together, these metrics make up most of what people perceive as website speed.
Site speed is a direct part of Google's Page Experience ranking signal, so a poor performance score hurts both your search rankings and your conversion rate. Studies show a meaningful share of visitors abandon a page once load time passes 3 seconds — a direct revenue loss for e-commerce and lead-generation sites alike.
The generally accepted rule-of-thumb targets are: LCP under 2.5 seconds is good, CLS under 0.1 is good, and TBT under 200 milliseconds is good. If your score falls short of these thresholds, technical website speed optimization — image compression, caching, code splitting, and trimming third-party scripts — can close the gap.

Open pageA score of 90-100 is considered "good," 50-89 is "average" and needs improvement, and anything below 50 is "poor" and needs urgent attention. Google uses mobile performance as a ranking signal, so aim to keep your mobile score at 90 or above.
Mobile devices typically have slower processors and network connections, so Google runs mobile tests under stricter simulated conditions (throttled CPU and 4G network). This means the same site can score noticeably lower on mobile than on desktop. This tool focuses on the mobile strategy since most traffic is mobile.
We recommend testing after every major design or content update, plus a routine monthly check. Plugin updates, new images, or third-party scripts (live chat widgets, ad pixels) can quietly degrade your score over time.
Yes. Core Web Vitals are part of Google's Page Experience ranking signal. Slow-loading pages both rank lower and drive up bounce rates, costing you conversions. That's why website speed optimization matters for both SEO and conversion rate.
