Website performance directly impacts user experience, SEO rankings, and conversion rates. Google's Core Web Vitals — Largest Contentful Paint (LCP), Cumulative Layout Shift (CLS), and Interaction to Next Paint (INP) — are now official ranking signals used to determine your position in search results. A slow website doesn't just frustrate visitors; it actively costs you organic search traffic and lost revenue with every extra second of load time.
OpDeck's Website Performance tool runs a full Google PageSpeed Insights audit against your URL, returning scores across four categories: Performance, Accessibility, SEO, and Best Practices. You get concrete metrics with millisecond-level precision alongside prioritized recommendations — eliminating render-blocking resources, compressing images, deferring unused JavaScript, and fixing accessibility violations. Use it before and after every deployment to track regressions and measure the real-world impact of your optimizations.
