Lighthouse
Lighthouse is a free auditing tool from Google that grades a web page and hands back specific fixes across five areas: performance, accessibility, best practices, SEO, and progressive-web-app readiness. Each area scores from 0 to 100, and a performance score above 90 is considered good. You can run it inside Chrome’s developer tools, through PageSpeed Insights, or from the command line for automated testing. One thing to keep in mind: Lighthouse simulates a throttled mid-range phone, so its numbers reflect a lab test rather than your real visitors, which is why you confirm anything important against field data from PageSpeed Insights or Search Console.
Also known as: Google Lighthouse, Lighthouse audit, Lighthouse score, PageSpeed
Where this term comes up
-
Will my Lighthouse score hit 100?
Probably not, and chasing 100 is a bad goal. The right goal is field Core Web Vitals in the green for the templates that actually drive revenue. Lighthouse is a lab tool; CrUX is what Google ranks on.
-
Can you guarantee a specific Lighthouse score?
No, and any agency that does is selling you a number, not an outcome. The goal is field Core Web Vitals in the green for the templates that drive revenue. Lighthouse is a lab tool; CrUX is what Google ranks on. The after-report shows the numbers honestly, whichever way they moved.

Glossary entries are a starting point. The real question is usually what to do about the thing once you understand it.
When you are ready to go further, the related guides take this from definition to fix.
And if you would rather just ask a person, I read everything that comes to christopher@thisismyurl.com.
I have been working in WordPress since 2007, so most of these terms come with a story.
