Continuous Core Web Vitals monitoring — not just one-time audits

Continuous tracking of LCP (Largest Contentful Paint), CLS (Cumulative Layout Shift), and INP (Interaction to Next Paint) on every page of your site. Unlike one-time speed tests, monitoring captures regressions caused by deploys, third-party scripts, or content changes — alerting you before Google's field data picks them up.

PageSpeed Insights runs a single one-shot Lighthouse audit. PerfBee runs those audits on a schedule across every page in a monitor, keeps each page's own history, compares each run against the one before it, and emails you when a score or a Core Web Vital regresses past a threshold you set — turning Lighthouse from a debugging tool into an early-warning system.

Lighthouse CI runs as part of your build pipeline and requires self-hosting plus configuration. PerfBee is fully hosted — no infrastructure to manage. You point it at a site, PerfBee proposes one page per template (homepage, category, product detail), and you get scheduled monitoring of that whole set with thresholds out of the box.

Yes — from real-user field data, not from the lab. INP (Interaction to Next Paint) replaced FID as a Core Web Vital in March 2024, and Lighthouse does not emit it in a lab run. PerfBee reads INP from the Chrome UX Report (CrUX), the same 28-day field dataset Google itself uses, and shows the p75 value against the 200ms and 500ms thresholds. Sites with too little Chrome traffic have no CrUX record, so INP is unavailable for them.

You pick the cadence when you create a monitor: daily, weekly, or monthly, at an hour you choose in your own timezone. Every page in that monitor is audited on that schedule. You can also run an audit on demand from the dashboard at any time.

Yes. Google confirmed Core Web Vitals as a ranking signal in 2021 as part of the Page Experience update. Pages that pass all three thresholds (LCP under 2.5s, CLS under 0.1, INP under 200ms) receive a ranking advantage over similar pages that fail. This makes continuous monitoring essential for competitive keywords.

For each failing Core Web Vital, PerfBee analyzes the Lighthouse audit data and generates specific, prioritized fix recommendations — e.g., which images to optimize, which scripts to defer, which CSS to inline. This turns a list of opportunities into a concrete action plan.
