Priority fixes for oed.com
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.
89% of Literary & Knowledge peers do this. Limit: Certificate and protocol were observed from one vantage point; CDNs can present different certificates by region.
Priority 2 · Accelerate
No render-blocking scripts in <head>
Observed: The homepage <head> loaded 9 external scripts without async or defer.
What to do: Add defer to scripts that need the DOM, async to independent ones such as analytics, or move them to the end of the body.
On WordPress: Since WordPress 6.3, scripts can be registered with a defer or async loading strategy.
48% of Literary & Knowledge peers do this.

Priority 3 · Accelerate
Modern image formats in use
Observed: The homepage had 17 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.
On WordPress: WordPress has supported WebP uploads since 5.8 and AVIF since 6.5; image plugins or the host can convert existing images.
31% of Literary & Knowledge peers do this.
Guide: AVIF, WebP, JPEG, and PNG: Choose the Right Image Format
Priority 4 · Harden
DMARC policy enforces quarantine or reject
Observed: No DMARC record was found at _dmarc.oed.com.
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.
22% of Literary & Knowledge peers do this.
