Priority fixes for artexhibition.jp

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

1. Priority 1 · Harden

   DMARC policy enforces quarantine or reject

   Observed: No DMARC record was found at _dmarc.artexhibition.jp.

   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.

   44% of Events & Online Ticketing peers do this. Limit: Read from public DNS at the time of the check; records may have changed since.

2. Priority 2 · Accelerate

   Static files cached for 30 days or more

   Observed: A same-site stylesheet or script was cacheable for no max-age, 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.

   On WordPress: Caching plugins or your host can set long browser cache lifetimes for theme and plugin assets.

3. Priority 3 · Accelerate

   Modern image formats in use

   Observed: The homepage had 75 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.

4. Priority 4 · Accelerate

   No render-blocking scripts in <head>

   Observed: The homepage <head> loaded 3 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.
