Priority fixes for sonnenklar.tv
Ordered by impact and by how common each practice is among peers.
Priority 1 · Accelerate
No render-blocking scripts in <head>
Observed: The homepage <head> loaded 2 external scripts without async or defer.
Why it matters: A plain <script src> in the head stops the browser from showing anything until that file has downloaded and run.
What to do: Add defer to scripts that need the DOM, async to independent ones such as analytics, or move them to the end of the body.
44% of Travel Bookings & Trip Planning peers do this. Limit: Based on the homepage HTML delivered to an automated client; scripts that run later were not executed.
Guide: Control Third-Party Scripts Before They Control Your Page
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.
56% of Travel Bookings & Trip Planning 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.
68% of Travel Bookings & Trip Planning 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.
33% of Travel Bookings & Trip Planning peers do this.
