What this check looks for
Google measures Largest Contentful Paint, Interaction to Next Paint, and Cumulative Layout Shift. Miss the thresholds (LCP > 2.5s, INP > 200ms, CLS > 0.1) and you're flagged in Search Console as needing improvement. Most SaaS sites lose here on hero images that aren't compressed, third-party tag loaders firing on the critical path, and webfont swaps that shift the layout. Audit with PageSpeed Insights, then fix the biggest contributor first.
Quick take
Page speed is a Core Web Vitals ranking signal and an honest conversion lever. Slow pages bleed both rank and revenue. Most SaaS sites in this gallery fail the check on the same three culprits: hero images, third-party marketing tags, and webfont swaps.
Why this matters
Google measures Largest Contentful Paint, Interaction to Next Paint, and Cumulative Layout Shift on real Chrome users. Miss the thresholds (LCP > 2.5s, INP > 200ms, CLS > 0.1) and Search Console flags the URL group as "needs improvement" inside the Core Web Vitals report. The conversion damage lands first: every 1 second of mobile load time costs about 7% in conversion (Akamai 2017 study, replicated by Deloitte's Milliseconds Make Millions in 2020). The ranking damage lands later, but it lands.
How to fix it (3 steps)
-
1
Run PageSpeed Insights on your slowest top-traffic URL
Open
pagespeed.web.dev, paste the URL, look at LCP first. On most pages it's one image above the fold. Fixing the LCP element usually fixes the score on its own. -
2
Compress and lazy-load images, set explicit width/height
Convert hero images to WebP or AVIF. Lazy-load anything below the fold with
loading="lazy". Setwidthandheightattributes on every<img>so the browser reserves space and CLS stays under 0.1. -
3
Defer or load-on-interaction every third-party script
Analytics, chat widgets, marketing tags. They're the largest INP killer on most pages. Mark them
asyncordefer, or load them only after the user scrolls or clicks. Audit your tag manager once a quarter — most sites carry tags from vendors they stopped using two years ago.
