Priority fixes for dumpert.nl
Ordered by impact and by how common each practice is among peers.
Priority 1 · Enable
Canonical URL declared
Observed: The homepage did not declare a canonical URL.
Why it matters: A canonical link tells search engines which URL to show when the same page is reachable at several addresses.
What to do: Add a self-referencing canonical link to every indexable page, using the final https:// URL.
69% of Entertainment & Video Streaming peers do this. Limit: Based on the homepage HTML delivered to an automated client; scripts that run later were not executed.
Priority 2 · Harden
Framing restricted
Observed: The homepage did not send frame-ancestors or X-Frame-Options, so other sites may frame it.
What to do: Send Content-Security-Policy: frame-ancestors 'self' (or a list of trusted origins). X-Frame-Options: SAMEORIGIN covers older browsers.
On Cloudflare: Add the header with a response header transform rule.
43% of Entertainment & Video Streaming 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.
65% of Entertainment & Video Streaming 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.
On Cloudflare: Enable HTTP/3 (with QUIC) under Speed > Optimization > Protocol Optimization.
34% of Entertainment & Video Streaming peers do this.
