Run a performance scanner that measures LCP, INP, and CLS against Google's thresholds. Seoxpert evaluates Core Web Vitals on every crawled page and flags the upstream causes — render-blocking scripts, uncompressed assets, images without dimensions, slow server response. Free first scan.
Core Web Vitals are Google's ranking-relevant performance metrics: Largest Contentful Paint (LCP, should be under 2.5 s), Interaction to Next Paint (INP, under 200 ms), and Cumulative Layout Shift (CLS, under 0.1). A page that fails any of them can be penalized in rankings, especially on mobile.
Seoxpert is a simple website audit platform for small businesses and agencies. It scans for SEO, security, and performance issues in one pass — with a prioritized fix list and a free first scan. Every crawled page is evaluated against the three CWV thresholds, and the upstream causes are flagged: render-blocking head scripts, stylesheets in the head, images without width/height (a CLS contributor), missing font-display, uncompressed text assets, and slow Time to First Byte.
Google PageSpeed Insights audits one URL at a time using lab data; it is free and worth running. Seoxpert complements it by scanning every page in one pass and rolling the findings up by severity, so you can see which 5 pages need urgent work.
