Core Web Vitals
Core Web Vitals are a group of metrics Google uses to gauge the quality of a page’s user experience from real browsing data. There are three: LCP, which measures how long the main content takes to load; INP, which assesses how quickly the page responds to interactions; and CLS, which reflects visual stability — whether elements jump around annoyingly while it loads. Google uses them as a ranking factor within its page-experience signal, though relevant content still counts for more. You can check them in tools like Search Console or PageSpeed Insights. Good scores improve both visitor satisfaction and, indirectly, SEO SEO (search engine optimization) covers all the measures that get a website to appear higher in Google's unpaid results and thereby attract more visitors.
