What this Website Speed Checker reviews
The automated scan reviews server response time, time to first byte, HTML size, HTTP status, redirects, HTTPS, compression, browser caching, mobile viewport, DOM size, images, modern image formats, lazy loading, scripts, stylesheets, videos, third-party assets, and platform clues.
Why website speed matters for SEO and conversions
Slow responses and heavy pages can increase abandonment, reduce landing-page engagement, and make mobile forms, products, and content harder to use. Technical performance supports search visibility, paid campaign efficiency, and conversions.
Common website speed issues
Typical issues include slow hosting, oversized HTML, missing Brotli or Gzip compression, weak cache headers, non-modern images, missing lazy loading, excessive JavaScript, too many stylesheets, and heavy third-party resources.
