Priority fixes for al-in.fr
Ordered by impact and by how common each practice is among peers.
Priority 1 · Accelerate
HTTP/2 negotiated
Observed: The TLS handshake selected HTTP/1.1 instead of HTTP/2.
Why it matters: HTTP/2 sends many files over one connection, which speeds up pages with lots of images, styles and scripts.
What to do: Enable HTTP/2 on your CDN or server. Most CDNs do this by default.
91% of Real Estate & Property Listings peers do this. Limit: Certificate and protocol were observed from one vantage point; CDNs can present different certificates by region.
Priority 2 · Enable
robots.txt published
Observed: No robots.txt file was returned at the site root.
What to do: Publish /robots.txt with any crawl rules you need and a Sitemap: line pointing to your XML sitemap.
94% of Real Estate & Property Listings peers do this.

Priority 3 · Enable
XML sitemap discoverable
Observed: No sitemap was listed in robots.txt or found at /sitemap.xml.
What to do: Generate an XML sitemap of canonical URLs, reference it in robots.txt and submit it in Google Search Console.
74% of Real Estate & Property Listings peers do this.

Priority 4 · Harden
DMARC policy enforces quarantine or reject
Observed: No DMARC record was found at _dmarc.al-in.fr.
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.
51% of Real Estate & Property Listings peers do this.
