Vitki · performance scan

Find out how fast your site really is. Results emailed in 1–3 minutes

One scan of your homepage. We run a full Lighthouse audit and grade your site against Google's Core Web Vitals thresholds: LCP, CLS, FCP, TTFB, and Total Blocking Time. You also get render-blocking resource detection, image optimization checks, caching analysis, and third-party script impact. Letter grade and top issues, by email. No phone call, no upsell drip.

The homepage is enough. We scan one page on the quick scan.

We send the report once. No marketing list, no drip campaign.

Scan typically completes in 1–3 minutes

What you get

  • Performance grade A–F. Graded against Google's published Core Web Vitals thresholds — the same metrics Google uses as a ranking signal.
  • Core Web Vitals. LCP, CLS, FCP, TTFB, Total Blocking Time, and Speed Index — each rated good, needs improvement, or poor.
  • Lighthouse Performance score. The same 0–100 score from Google's own auditing tool, with context on what it means.
  • Render-blocking resources. JavaScript and CSS files that delay first paint — with estimated time savings.
  • Image optimization. Uncompressed images, missing modern formats (WebP/AVIF), and oversized images — with byte savings.
  • Caching & compression. Missing Cache-Control headers, short cache lifetimes, and uncompressed text resources.
  • Third-party impact. How much third-party scripts (analytics, ads, widgets) add to page weight and blocking time.
  • Actionable fix suggestions. Every finding comes with a plain-English remediation step.

Want help fixing these?

The quick scan covers your homepage. A multi-page audit checks every page for slow LCP elements, render-blocking chains, image pipelines, and third-party script sprawl across your entire site.

Vitki Forge offers hands-on performance optimization — Core Web Vitals fixes, image pipelines, caching strategy, and third-party script audits.
