Priority fixes for uwaterloo.ca
Ordered by impact and by how common each practice is among peers.
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.
82% of Education & Online Learning peers do this. Limit: Only the standard location was requested, once, at the time of the check.

Priority 2 · Harden
DMARC policy enforces quarantine or reject
Observed: The DMARC policy for uwaterloo.ca 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.
36% of Education & Online Learning peers do this.
Priority 3 · Accelerate
Modern image formats in use
Observed: The homepage had 3 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.
32% of Education & Online Learning peers do this.

52% of Education & Online Learning peers do this.
