Failing Core Web Vitals
Google's Core Web Vitals (LCP, FID/INP, CLS) failing thresholds, directly impacting search rankings and user experience.
What You're Seeing
- Google Search Console shows Core Web Vitals issues
- Poor scores in PageSpeed Insights
- Search rankings dropping despite good content
Why This Happens
- 1Slow server response time affecting LCP
- 2Heavy JavaScript execution causing poor INP
- 3Layout shifts from images without dimensions or dynamically injected content
- 4Unoptimized fonts causing FOUT/FOIT
How We Fix It
Our senior engineers follow this systematic approach to resolve the issue quickly and permanently.
LCP (Largest Contentful Paint): Optimize the largest element on the page — usually a hero image. Preload it, use proper sizing, serve via CDN.
INP (Interaction to Next Paint): Reduce JavaScript execution time, break up long tasks, use web workers for heavy computation.
CLS (Cumulative Layout Shift): Set explicit width/height on images and videos, reserve space for ads and embeds, avoid inserting content above existing content.
Font Loading: Use font-display: swap, preload critical fonts.
Preventing This Issue
Monitor Core Web Vitals in Google Search Console weekly, set performance budgets, test on real mobile devices, implement Real User Monitoring (RUM).
Related Guides
If you're experiencing this issue, you may also want to check these related problems:
- Slow Page Load Speed - Website pages load slowly, causing high bounce rates and poor search rankings. Slow website speed affects user experience, conversions, and SEO performance.
- Large Unoptimized Images - Oversized images are the most common cause of slow websites. Unoptimized images waste bandwidth, increase load times, and hurt Core Web Vitals scores.
- Render-Blocking Resources - JavaScript and CSS files that block the browser from rendering the page, causing delayed First Contentful Paint and poor user experience.
