The problem
Most Webflow agencies check performance ad-hoc, if at all. By the time a client complains, the damage is done.

FAQ
Lighthouse in Chrome DevTools runs from your machine — results vary by network, hardware, and location. Site Health runs each audit on Google's own PageSpeed Insights infrastructure, giving you consistent, reproducible scores that match what Google actually sees. It also runs across every page automatically, not just the ones you remember to check.
Yes. For CMS collection template pages, Site Health resolves to a real live item URL so Google PageSpeed Insights scans actual content — not an empty template. You'll see scores for individual blog posts, product pages, and any other CMS-driven pages.
Site Health connects via Webflow OAuth and only requests read access to your site list and published pages. It never writes to your Webflow account, and you can revoke access at any time from Webflow's integrations settings.

You can schedule daily or weekly scans. A webhook trigger is also available so a scan fires automatically every time you publish your Webflow site — catching regressions the moment they go live.
Core Web Vitals are the three speed metrics Google uses as a confirmed ranking factor: LCP (Largest Contentful Paint — how fast the main content loads), CLS (Cumulative Layout Shift — how much the page jumps around), and INP (Interaction to Next Paint — how quickly it responds to clicks). Poor scores can hurt your position in search results.
