Summary
What This Tool Tests
Your site is tested against the same criteria Google uses to evaluate page experience.
Load Your Page
We fetch your URL and load it in a controlled Lighthouse environment — the same engine Google uses for PageSpeed Insights.
Measure Load Times
Every millisecond is tracked: First Contentful Paint, Largest Contentful Paint, Speed Index, and Time to Interactive.
Evaluate Core Web Vitals
LCP, TBT, and CLS are measured against Google thresholds to determine if your page passes real-world user experience standards.
Identify Improvements
The audit pinpoints exactly what is slowing your site down — with estimated time savings for each fix, sorted by impact.
Understanding Your Score
Your performance score is a weighted average of six metrics. Here is what each score range means and what to prioritize.
Your page loads quickly and provides a smooth user experience. Maintain this with regular monitoring.
There are clear optimization opportunities. Focus on the items in the Opportunities section — they are sorted by impact.
Significant performance issues are hurting your conversions and SEO. Prioritize server response time, image optimization, and JavaScript reduction.
LCP — Largest Contentful Paint
How fast the main content loads
TBT — Total Blocking Time
How responsive the page feels
CLS — Cumulative Layout Shift
How stable the visual layout is
FCP — First Contentful Paint
When the first content appears

Frequently Asked Questions
This tool uses Google PageSpeed Insights and Lighthouse to analyze your website. It loads your page in a controlled environment, measures real load times, evaluates Core Web Vitals, and identifies specific opportunities to improve performance — the same engine Google uses to evaluate your site.
Scores of 90 to 100 are considered good. 50 to 89 needs improvement. Below 50 is poor. Most websites score between 40 and 70 on mobile. Desktop scores are typically 10 to 20 points higher because desktop devices have more processing power and faster connections.
Core Web Vitals are three metrics Google uses to evaluate real-world user experience. Largest Contentful Paint (LCP) measures loading speed. Total Blocking Time (TBT) measures interactivity and responsiveness. Cumulative Layout Shift (CLS) measures visual stability. All three directly affect your search rankings.
Mobile analysis simulates a mid-tier phone on a throttled 4G connection, while desktop uses a faster connection and more powerful hardware. This reflects real-world conditions — most mobile users have limited bandwidth and processing power compared to desktop users.
Test after every deployment, monthly for routine monitoring, and before and after any major change like a redesign, plugin installation, or hosting migration. Performance degrades gradually as content, scripts, and third-party tags accumulate over time.
Yes. Google uses Core Web Vitals as a confirmed ranking factor. Pages with good LCP, INP, and CLS scores get a ranking boost in search results. Slow pages also suffer higher bounce rates, which indirectly hurts SEO through reduced engagement signals.
For most sites, the biggest gains come from optimizing images (compression, modern formats, lazy loading), removing unused JavaScript, and improving server response time. These three changes alone can improve performance scores by 20 to 40 points.
Yes, completely free with no account required. This tool uses the same Lighthouse engine that powers Google PageSpeed Insights. Test as many pages as you need — there are no limits or sign-up requirements.
