Problem with CLS
71 USD A specialist in Core Web Vitals optimization is needed. According to Google Search Console, we have 10 "bad" URLs and 199 URLs with a status of "needs improvement" on mobile devices, and 232 URLs in the yellow zone and none in the green on desktop. Task: conduct an audit, identify the reasons for low metrics (LCP, CLS, INP, TTFB), eliminate them — optimization of images, JS/CSS, caching, CDN — and move the maximum number of pages to "Good" status. Changes should be made without disrupting the functionality of the site, attach a report before and after with confirmation in PageSpeed Insights.

Hello, I have been working on optimizing Core Web Vitals for a medical portal with over 50,000 pages - improved CLS from 0.4 to 0.05, LCP from 4.2s to 1.8s, which raised 89% of URLs from "needs improvement" to "Good."
Is the issue with CLS related to dynamic elements (ads, modal windows) or asynchronous content loading?
I suggest we get in touch, I will provide you with a free consultation on the technical side and we will create a development plan + I will tell you about my team!

Good day!
I am ready to help with the complete optimization of Core Web Vitals and bringing pages into the "Good" zone.
What I will do:
• Conduct a detailed audit (LCP, CLS, INP, TTFB) using PageSpeed Insights + Lighthouse + real data from GSC
• Identify specific causes of issues (render-blocking resources, heavy images, JS, fonts, server)
• Optimize:
… — images (WebP/AVIF, lazy loading, correct sizes)
— CSS/JS (defer, critical CSS, code splitting)
— caching (browser + server)
— connecting CDN (if necessary)
— reduce TTFB (backend/hosting optimization)
• Eliminate CLS (layout shift)
• Improve INP (interaction and JS optimization)
Result:
✔ Maximum conversion of URLs to "Good" status
✔ No functionality breakage
✔ "Before/After" report with confirmation in PageSpeed Insights
✔ Recommendations for maintaining the result
I have experience optimizing WordPress and Next.js projects (including complex cases with CWV).
I can start immediately after brief access to the site.
