Since 2021, Google has been using Core Web Vitals metrics directly as a ranking factor. LCP (Largest Contentful Paint), CLS (Cumulative Layout Shift), and INP (Interaction to Next Paint) — these three metrics are the core benchmarks of user experience, and poor scores can leave your site behind your competitors. The SEOYEN Core Web Vitals tool measures your entire site’s metrics using real user data, shows historical trends, and clearly reveals which pages should be improved first.
What Are Core Web Vitals?
Core Web Vitals are the three critical performance metrics Google has defined to measure user experience. These metrics are compiled from real users’ browsers in Google’s CrUX (Chrome User Experience Report) database; in other words, they come not from lab tests but from the experience of people actually visiting your site. The SEOYEN Core Web Vitals tool analyzes this real user data (CrUX) separately for desktop and mobile devices, at both the page and sitewide levels, providing visibility that goes far beyond PageSpeed Insights.
The Three Core Metrics
- LCP — Largest Contentful Paint: The time it takes for the largest image or text block on the page to become visible on screen. Good threshold: under 2.5 seconds. Slow LCP is usually caused by large images, slow server response times, or render-blocking CSS/JS.
- CLS — Cumulative Layout Shift: The amount of unexpected movement of visual elements while the page is loading. Good threshold: under 0.1. Ad banners, late-loading images, or font swaps without defined dimensions increase CLS.
- INP — Interaction to Next Paint: The page’s response time to user interactions such as clicking a button or filling out a form. It replaced FID in March 2024. Good threshold: under 200ms.
How Does It Work?
- CrUX Data Integration: Pulls real user data from Google’s Chrome User Experience Report API to show origin-level and page-level metrics for each page.
- PageSpeed Insights Integration: Using the user’s own PageSpeed API key, it automatically applies lab tests to all crawled pages across the site; in addition to LCP, CLS, and INP, TTFB and FCP values are reported for each page.
- Batch Testing: After the Site Audit is completed, the CWV values of hundreds of pages are automatically measured in the background; the worst-performing pages are highlighted.
- Mobile / Desktop Separation: Each metric is reported separately for mobile and desktop devices. Considering that mobile scores are often lower and that Google uses mobile-first indexing, this distinction is critical.
- Historical Trend: You can track changes over time on a chart and prove the impact of your performance improvements with concrete data.
Who Should Use It?
- Web developers: To measure whether performance improvements are reflected in real users and determine which pages should be optimized first.
- SEO specialists: To monitor the impact of Google’s Page Experience update and compare the effect of Core Web Vitals on rankings against competitor sites.
- E-commerce managers: To increase conversion rates by monitoring the loading speed of checkout and product pages. (The correlation between CWV and conversion rate can reach up to 24%.)
- Content managers and editors: To track the performance of newly published articles and report slow-loading content to the development team.

Frequently Asked Questions
What thresholds should I reach to pass Core Web Vitals?
Google’s “Good” thresholds are: LCP ≤ 2.5 seconds, CLS ≤ 0.1, and INP ≤ 200ms. For a page to meet these values, it must stay below these thresholds at the 75th percentile (that is, the experience of at least 75% of visitors). The “Poor” thresholds are LCP > 4s, CLS > 0.25, and INP > 500ms.
What should be done for a page without CrUX data?
The CrUX database may not contain data for pages that do not receive enough traffic. In that case, SEOYEN shows origin-level (domain-level) data if available. If neither data source exists, PageSpeed Insights lab test results are used.
What should I do to improve LCP?
The most common ways to improve LCP are: converting the hero image to WebP/AVIF format and preloading it, using a CDN to reduce server response time (TTFB), deferring CSS and JavaScript files, compressing large images, and applying lazy loading only to below-the-fold images.
How is INP different from the old FID metric?
While FID (First Input Delay) measures only the first user interaction on the page, INP evaluates all interactions throughout the session and reports the worst one. INP reflects real user experience much more comprehensively and became the official successor to FID in March 2024.
How much does CWV affect rankings?
Google has confirmed that it uses Core Web Vitals as a ranking factor under the Page Experience signal. However, content quality and relevance are still the primary factors. The real value of CWV is that it creates differentiation between two sites with the same content quality — which makes it critically important when competing against technically superior competitors.
