# Core Web Vitals history

See how a page's real-user LCP, INP and CLS changed week by week over the last six months. Free, no sign-in, from Chrome's own field data.

Page or site address 

## What the charts show

Each line is the 75th percentile of real Chrome visits, the figure Google uses to judge a page. Each point covers the 28 days ending that week, so the line moves gradually. The dashed lines are Google's thresholds: below the lower one is good, above the upper one is poor.

PageSpeed Insights answers "how fast is this page now". This answers "since when": whether a release, a new script or a theme change made things worse, and whether a fix actually brought them back.

## Ask your assistant instead

GSC PAP puts this same history inside Claude, ChatGPT or Cursor, next to your Search Console and Google Analytics data. So the question can be the one you actually have: "did our clicks drop when LCP got worse on the product pages?" The assistant reads the weekly vitals, the clicks for the same weeks and the pages involved, and answers in one go.

Free, read-only, signs in with Google, no Google Cloud project. [How the Core Web Vitals audit works](https://gscpap.com/guides/audit-core-web-vitals-with-ai).

## Questions

### How do I see Core Web Vitals history for a page?

Enter the page on this tool. It reads the Chrome UX Report History API and shows the weekly 75th percentile for LCP, INP and CLS over the last 25 weeks, about six months. Search Console's Core Web Vitals report shows a 90-day chart of how many URLs pass, and PageSpeed Insights shows the current 28-day window only.

### Why is there no data for my site?

Chrome only publishes real-user data for a page or site once enough Chrome users have visited it in the last 28 days. Most new and small sites are below that threshold. When there is no data for the exact URL but there is for the site, the tool shows the site-wide figures and says so.

### What counts as good Core Web Vitals?

Google's thresholds, measured at the 75th percentile of visits: Largest Contentful Paint up to 2.5 seconds is good and over 4 seconds is poor; Interaction to Next Paint up to 200 ms is good and over 500 ms is poor; Cumulative Layout Shift up to 0.1 is good and over 0.25 is poor.

### Why does each point cover 28 days?

Chrome UX Report data is a rolling 28-day window, published weekly. A fix you ship today moves the line gradually over the next four weeks rather than in one step, so judge a change by the trend a month later, not the next point.
