Priority fixes for ich-tanke.de
Ordered by impact and by how common each practice is among peers.
Priority 1 · Accelerate
Static files cached for 30 days or more
Observed: A same-site stylesheet or script was cacheable for 24 days, short of the 30-day benchmark.
Why it matters: Returning visitors and later page views reuse cached files instead of downloading them again.
What to do: Give versioned (fingerprinted) CSS, JavaScript, fonts and images Cache-Control: public, max-age=31536000, immutable, and change the file name whenever the content changes.
55% of Cars & Automotive peers do this. Limit: Read from the homepage response only; other pages or regions may send different headers.
Priority 2 · Harden
DMARC policy enforces quarantine or reject
Observed: The DMARC policy for ich-tanke.de was p=none, which asks receivers to take no action on failing mail.
What to do: Publish DMARC with p=none and a reporting address first, fix any legitimate senders that fail SPF or DKIM alignment, then move to quarantine and finally reject.
41% of Cars & Automotive peers do this.
Priority 3 · Enable
Social preview image set
Observed: The homepage had no og:image, so shared links may show without a preview image.
What to do: Add Open Graph tags, including og:image with a 1200 x 630 image.
62% of Cars & Automotive peers do this.
Priority 4 · Accelerate
HTTP/3 advertised
Observed: The homepage did not advertise HTTP/3 through an Alt-Svc header.
What to do: Turn on HTTP/3 at your CDN. Browsers fall back to HTTP/2 automatically, so the risk is low.
30% of Cars & Automotive peers do this.
