Priority fixes for cookidoo.fr
Ordered by impact and by how common each practice is among peers.
Priority 1 · Harden
DMARC policy enforces quarantine or reject
Observed: No DMARC record was found at _dmarc.cookidoo.fr.
Why it matters: An enforcing DMARC policy helps receiving mail systems reject email that falsely claims to come from your domain, a common route for phishing your customers.
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.
42% of Food & Grocery Delivery peers do this. Limit: Read from public DNS at the time of the check; records may have changed since.
Priority 2 · Accelerate
Modern image formats in use
Observed: The homepage had 72 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.
40% of Food & Grocery Delivery peers do this.
Guide: AVIF, WebP, JPEG, and PNG: Choose the Right Image Format
Priority 3 · Enable
Canonical URL declared
Observed: The homepage did not declare a canonical URL.
What to do: Add a self-referencing canonical link to every indexable page, using the final https:// URL.
80% of Food & Grocery Delivery peers do this.
Priority 4 · Accelerate
Offscreen images lazy-loaded
Observed: The homepage had 72 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.
63% of Food & Grocery Delivery peers do this.
