// Lighthouse Vitals

Your web experience is part of your ad budget.

We measure your site's Core Web Vitals - loading, responsiveness and visual stability - on mobile and desktop, then show what a slow or unstable page costs the traffic you pay to send there. One score, in about a minute.

We run Google's PageSpeed analysis on your page - with real-user field data where it exists - for both mobile and desktop. Your ad-spend band is only used to estimate the cost on this page. Nothing is stored.
