What the audit measures.
- Performance scoreA score from 0 to 100 worked out by Lighthouse, Google's tool, on a simulated mobile load. According to our Core Web Vitals article, a score under 50 usually points to structural problems rather than a simple setting.
- LCP (Largest Contentful Paint)How long before the page's main content is visible. Google's thresholds: good up to 2.5 s, needs improvement up to 4 s, poor beyond.
- INP (Interaction to Next Paint)The delay between a click and the page visibly reacting. Good up to 200 ms, poor beyond 500 ms. INP is measured on real visitors: without enough traffic, the tool shows TBT (Total Blocking Time) instead, a lab measure of how long JavaScript blocks the page.
- CLS (Cumulative Layout Shift)Layout shifts during loading, when a button moves just as you click. Good up to 0.1, poor beyond 0.25.
- Lab or fieldThe score and lab measures come from a simulation. When Google has enough data, the tool also shows field measures, taken from real Chrome visitors (CrUX report). These are the ones that count for Google. See the thresholds table.
Is your website too slow?
Heavy images, no caching, blocking scripts, slow hosting: I fix these causes and keep an eye on your site as part of WordPress maintenance, from €40 excl. VAT / month.
Frequently asked questions.
Where do the results come from?
From Google's public PageSpeed Insights API, queried by your browser when you click. The test simulates a mobile load with Lighthouse and adds, where available, measurements from real Chrome visitors (CrUX).
Why does my score change from one test to the next?
The score comes from a simulation: server load, network and third-party content (ads, widgets) vary between tests. Field measures, when available, are more stable.
What are the right thresholds?
Google's: LCP up to 2.5 s, INP up to 200 ms, CLS up to 0.1. The details are in our Core Web Vitals article.
My website is slow: where do I start?
Usually with images (WebP format, right dimensions), then caching, unnecessary plugins and scripts, and hosting. See the 5 most common causes of a slow website.
