Priority fixes for libreoffice.org

Ordered by impact and by how common each practice is among peers.

1. Priority 1 · Enable

   robots.txt published

   Observed: No robots.txt file was returned at the site root.

   Why it matters: robots.txt is where crawlers look first for crawl rules and sitemap locations. Without it, they assume everything is open.

   What to do: Publish /robots.txt with any crawl rules you need and a Sitemap: line pointing to your XML sitemap.

   92% of Work Productivity Apps peers do this. Limit: Only the standard location was requested, once, at the time of the check.

2. Priority 2 · Harden

   DMARC policy enforces quarantine or reject

   Observed: The DMARC policy for libreoffice.org was p=none, which asks receivers to take no action on failing mail.

   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.

   54% of Work Productivity Apps peers do this.

3. Priority 3 · Accelerate

   Static files cached for 30 days or more

   Observed: A same-site stylesheet or script was cacheable for 7 days, short of the 30-day benchmark.

   What to do: Give versioned (fingerprinted) CSS, JavaScript, fonts and images Cache-Control: public, max-age=31536000, immutable, and change the file name whenever the content changes.

   53% of Work Productivity Apps peers do this.

4. Priority 4 · Accelerate

   Modern image formats in use

   Observed: The homepage had 27 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.

   43% of Work Productivity Apps peers do this.
