Catch the page-level issues that wreck your Core Web Vitals — slow TTFB, lazy-loaded hero images, render-blocking scripts, and layout shift — before they cost you rankings.
Core Web Vitals are a confirmed Google ranking factor, but the field scores you see in Search Console are downstream of fixable, page-level mistakes. This tool measures your server's time to first byte and inspects the HTML for the patterns that wreck LCP and CLS — lazy-loaded hero images, render-blocking scripts, and images without dimensions — so you can fix the causes instead of guessing at the symptoms.
60 automated checks across meta tags, robots.txt, Open Graph, sitemaps, headings, AI visibility, and more — free, no signup.
