What this tool measures

The test queries Google's official PageSpeed Insights API and returns what really matters for your site's performance and ranking. The general performance score, from 0 to 100, is the same one Google uses as a signal in its algorithm. And the Core Web Vitals —the three metrics Google considers essential— tell you exactly where the problem is, if there is one.

The Core Web Vitals, in simple terms

LCP (Largest Contentful Paint) measures how long the page's main content takes to appear; Google considers good less than 2.5 seconds. INP (Interaction to Next Paint) measures how fast the page responds when someone interacts with it; good is less than 200 milliseconds. And CLS (Cumulative Layout Shift) measures how much the elements move while loading —those annoying jumps that make you tap the wrong button—; good is less than 0.1.

Why your site's speed is money

Speed is not a technical whim. Google uses it to decide your position in the search results, so a slow site appears lower and receives fewer visits. And the user is even less patient: an important portion of visitors abandons a site that takes more than three seconds to load, especially from the phone. Each extra second translates into lost visitors, worse ranking and, in a store, sales that do not happen. That is why measuring is the first step: you cannot improve what you do not measure.

Did your site come out slow? Here is how to fix it

If your score is below 90, there is room for improvement, and the cause is almost always one of these: heavy unoptimized images, excess scripts and plugins, a loaded template, or slow hosting. Sometimes it is resolved by optimizing what you already have; other times, when the site is built on too heavy a base, it is more profitable to rebuild it on a modern architecture than to fight against its limits. We build sites that get 100 in this very test: if you want to know what can be done with yours, we tell you honestly.
