Largest Contentful Paint, Cumulative Layout Shift, and Interaction to Next Paint — the same metrics Google uses as ranking signals.
Separate scores for both, since mobile performance is what most of your visitors — and Google's mobile-first indexing — actually experience.
Not just a score — specific diagnostics on what's slowing the page down, so you know exactly what to fix first.
Yes — no sign-up, no credit card, no limit on how many URLs you can test. It's powered by the same Google PageSpeed Insights engine as the Page Speed module inside our paid SEO Audit tool.
It isn't a different data source — it's the same PageSpeed Insights data, presented alongside the rest of the GrowLytics platform so you can move straight into a full SEO Audit or URL Indexing without switching tools.
The free tool checks one URL at a time. For bulk, scheduled checks across a whole site with historical trend tracking, that's part of the paid SEO Audit tool's Page Speed and CWV Trend History modules.
