Priority fixes for clever-tanken.de

Ordered by impact and by how common each practice is among peers.

1. Priority 1 · Enable

   robots.txt published

   Observed: No robots.txt file was returned at the site root.

   Why it matters: robots.txt is where crawlers look first for crawl rules and sitemap locations. Without it, they assume everything is open.

   What to do: Publish /robots.txt with any crawl rules you need and a Sitemap: line pointing to your XML sitemap.

   93% of Cars & Automotive peers do this. Limit: Only the standard location was requested, once, at the time of the check.

2. Priority 2 · Enable

   XML sitemap discoverable

   Observed: No sitemap was listed in robots.txt or found at /sitemap.xml.

   What to do: Generate an XML sitemap of canonical URLs, reference it in robots.txt and submit it in Google Search Console.

   83% of Cars & Automotive peers do this.

3. Priority 3 · Harden

   HSTS kept for at least a year

   Observed: The homepage response did not include a Strict-Transport-Security header.

   What to do: Send Strict-Transport-Security on HTTPS responses. Start with a short max-age (for example 300 seconds), confirm every subdomain works over HTTPS, then raise it in steps to 31536000. Add includeSubDomains only when all subdomains are HTTPS. HSTS preload is optional and hard to undo; hstspreload.org itself does not recommend it by default.

   41% of Cars & Automotive peers do this.

4. Priority 4 · Accelerate

   Modern image formats in use

   Observed: The homepage had 29 images and none used WebP or AVIF.

   What to do: Serve WebP or AVIF with a JPEG or PNG fallback, either through an image CDN or by generating both formats at build time.

   47% of Cars & Automotive peers do this.
