Google's page experience signals — LCP, INP, and CLS — are direct ranking factors. Our Core Web Vitals service diagnoses and fixes the exact issues dragging your scores below Google's 'Good' thresholds, improving both rankings and real user experience.
Core Web Vitals are a set of three specific page experience metrics that Google uses as ranking signals. They were introduced as part of the 2021 Page Experience update and have become progressively more important as Google's algorithm has matured. In 2024, INP replaced FID as the third Core Web Vital, making responsiveness measurement more comprehensive.
What makes Core Web Vitals unique as ranking signals is that they're based on real user experience data collected from Chrome browsers (CrUX data) — not synthetic measurements. This means your rankings are affected by how real visitors experience your site, not just how it performs in a lab environment. A site that loads quickly for your development team's fiber connection but slowly for your actual customers will have poor field data and be penalized accordingly.
Our Core Web Vitals optimization service goes beyond running Lighthouse and recommending image compression. We perform a forensic analysis of your specific site's performance bottlenecks, identify the exact resources and code patterns causing failures, and implement targeted fixes that move your scores into Google's 'Good' range — typically achieving measurable improvements within 60 days.
Measures how long it takes for the largest visible content element (hero image, heading, video) to fully render. Google considers LCP the most important perceived load speed metric.
Replaced FID in 2024. Measures your page's overall responsiveness to all user interactions — clicks, taps, keyboard input — throughout the entire page lifecycle.
Measures visual stability. High CLS means elements move around as the page loads — buttons shift, text jumps — creating a frustrating user experience and a negative ranking signal.
Yes — Core Web Vitals are a confirmed ranking signal as part of Google's Page Experience algorithm. Pages that pass all three Core Web Vitals thresholds ('Good' scores) get a small but meaningful ranking boost, particularly in mobile search results where performance gaps are most pronounced.
Lab data (from PageSpeed Insights, Lighthouse) is measured in a controlled environment. Field data (from CrUX — Chrome User Experience Report) reflects actual user experiences across the Chrome browser. Google uses field data for rankings — so even if your lab scores look good, poor field data is what affects your rankings.
Technical fixes can be implemented in days to weeks. However, Google typically takes 4–8 weeks to re-assess your field data scores after changes are made. You'll see improvements in PageSpeed Insights (lab data) immediately, but field data improvements in Search Console appear gradually over 4–8 weeks.
Mobile devices have slower CPUs, less memory, and slower network connections than desktop. A site that loads acceptably on desktop may have LCP failures on mobile because JavaScript execution takes longer and images take longer to download. Mobile-first optimization is essential.
