  Exposed Paths

  Publicly-readable sensitive paths detected: /.svn/entries. These should not be accessible without auth — they often leak source code, credentials, or backups.

  Viewport Meta Tag

  The viewport meta tag restricts user zoom capability (maximum-scale=1). This creates accessibility issues — users with visual impairments will not be able to enlarge the content. Google may consider this a degraded user experience.

  FAIL · performance

  Page Size

  The total HTML page size is 939.6 KB, which significantly exceeds the recommended limit of 100 KB. Heavy pages load slowly, especially on mobile devices and slow internet connections. This negatively impacts Core Web Vitals and search rankings.

  Time to First Byte (TTFB)

  Time to First Byte is 1480 ms (1.48 sec). Google flags this as "needs improvement" (800 ms – 1.8 s per web.dev). LCP is bounded by TTFB, so reaching the "good LCP" 2.5s threshold becomes harder as TTFB grows.

  Render-Blocking Resources

  Found 12 render-blocking resources (11 CSS, 1 JS) — this is too many. The browser must download and process all of these files before it can start rendering the page. This critically delays First Contentful Paint (FCP) and Largest Contentful Paint (LCP).

  Image Lazy Loading

  Only 8 out of 20 images (40%) use lazy loading — this is very low. The browser is forced to load most images immediately, even if they are far outside the visible area.

  HTTP Requests Count

  The page loads 118 external resources — this is too many (11 CSS, 66 JS, 19 images). A high number of HTTP requests critically slows down page loading, as browsers are limited to 6 simultaneous connections per domain. This negatively affects all performance metrics.

  Security Headers

  Found 5 out of 6 modern security headers. Missing: permissions-policy. Add the remaining headers to close defense-in-depth gaps. Note: Content-Security-Policy is the highest-impact header — if it is missing the site is exposed to XSS even when other headers are present.

  Server Signature

  The Server header is present: "Vercel". Although the exact version is not revealed, minimizing server information is recommended. The X-Powered-By header reveals the framework in use: "Next.js, Payload". This is a significant security risk — attackers gain information about the technology stack for targeted attacks.
