Core Web Vitals

First Contentful Paint
3.7 s
Time until the browser renders the first piece of content from the DOM. This is an important milestone for users to perceive that the page is loading.
Largest Contentful Paint
8.4 s
Time until the browser renders the largest text or image element. This marks the point where the main content of the page is likely loaded.
Total Blocking Time
1,510 ms
Sum of all time periods where the main thread was blocked long enough to prevent input responsiveness. Lower is better.
Cumulative Layout Shift
0.028
Measures visual stability by quantifying unexpected layout shifts of visible page content. Lower is better.
Speed Index
8.1 s
Shows how quickly the contents of a page are visibly populated. Lower is better.

Recommendations

  • Reduce JavaScript Blocking Time: Minimize third-party scripts, use async/defer loading, optimize JavaScript execution.
  • Remove Render-Blocking Resources: Inline critical CSS, defer non-critical JavaScript, use a Content Delivery Network (CDN).
  • Improve Largest Contentful Paint (LCP): Optimize images, lazy load offscreen images, use a faster CDN.
  • Improve First Contentful Paint (FCP): Reduce render-blocking CSS and JavaScript, enable server-side rendering.
  • Speed Index Can Be Improved: Reduce the number of large network requests and optimize fonts.

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.
