What are Core Web Vitals?

Core Web Vitals are a set of user-experience metrics that Google uses as ranking signals. They measure how fast content loads, how quickly the page responds to input, and how stable the layout is while loading. Poor scores can hurt rankings and user satisfaction.

The three metrics

• LCP (Largest Contentful Paint) — How long it takes for the main content (e.g. hero image or block of text) to appear. Lower is better; aim for under about 2.5 seconds.
• INP (Interaction to Next Paint) — How quickly the page responds to user input (clicks, taps). Replaces the older FID. Lower is better.
• CLS (Cumulative Layout Shift) — How much the layout jumps during load (e.g. images or ads pushing content down). Lower is better; aim for under about 0.1.

Why they matter for SEO

• Ranking — Page experience (including Core Web Vitals) is part of Google’s ranking criteria, especially on mobile.
• User experience — Good scores usually mean faster, more stable pages and better engagement.

How BearAudit uses them

BearAudit can optionally pull in PageSpeed Insights data (with your API key) to show desktop and mobile performance, including Core Web Vitals. You can see scores per page and prioritise fixes that improve LCP, INP, and CLS.
