Priority fixes for primainspirace.cz
Ordered by impact and by how common each practice is among peers.
Priority 1 · Accelerate
Modern image formats in use
Observed: The homepage had 41 images and none used WebP or AVIF.
Why it matters: WebP and AVIF are typically much smaller than JPEG or PNG at similar quality, and images are often the heaviest part of a page.
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.
On Cloudflare: Cloudflare Polish can convert images to WebP.
38% of Online Publishing peers do this. Limit: Based on the homepage HTML delivered to an automated client; scripts that run later were not executed.

Priority 2 · Accelerate
Offscreen images lazy-loaded
Observed: The homepage had 41 images and none used loading="lazy".
What to do: Add loading="lazy" to images below the fold. Do not lazy-load the main hero image, because that delays the largest visible element.
On WordPress: WordPress has added loading="lazy" to images by default since 5.5; check that your theme or a plugin has not removed it.
58% of Online Publishing peers do this.
Priority 3 · Harden
Content Security Policy present
Observed: The homepage response did not include a Content-Security-Policy header.
What to do: Start with Content-Security-Policy-Report-Only to see what would break, tighten the policy over a few weeks, then enforce it.

Priority 4 · Recover
Nameservers spread across providers
Observed: All nameservers for primainspirace.cz belong to Cloudflare.
What to do: Treat this as an advanced step. Add a secondary DNS provider through zone transfers or a multi-provider setup, then test changes carefully, since both providers must stay in sync.
On Cloudflare: Cloudflare supports zone transfers for primary or secondary DNS setups on eligible plans.
