Google PageSpeed Insights is the industry-standard tool for measuring Core Web Vitals and page speed — and it's genuinely excellent at that one job. Our AI Website Audit actually uses PageSpeed Insights data as part of its performance category, but goes considerably further, because speed is only one of the seven things that determine whether a website turns visitors into customers.
If you specifically need deep, technical Core Web Vitals diagnostics, PageSpeed Insights is the right specialist tool — and it's exactly what powers our own performance checks. If you want to understand your website's overall health across SEO, trust, accessibility and conversion in one plain-English report — not just speed — run our free AI Website Audit instead. Many businesses use both: PageSpeed Insights for deep technical performance work, and our audit for the full picture.
