Priority fixes for dtdc.com

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

1. Priority 1 · Harden

   HTTP requests move to HTTPS

   Observed: A request to http://www.dtdc.com/ was not redirected to HTTPS.

   Why it matters: Visitors who type the address or follow an old link start on unencrypted HTTP. A redirect moves them to the encrypted site before any cookies or form data are sent.

   What to do: Add a permanent (301 or 308) redirect from every http:// URL to the same https:// URL at your CDN, load balancer or web server.

   On WordPress: Set both WordPress Address and Site Address to https:// in Settings > General, then add the server or CDN redirect.

   90% of Postage & Courier Services peers do this. Limit: Measured for the homepage only, from one location, at the time of the check.

2. Priority 2 · Accelerate

   No render-blocking scripts in <head>

   Observed: The homepage <head> loaded 6 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.

3. Priority 3 · Harden

   Framing restricted

   Observed: The homepage did not send frame-ancestors or X-Frame-Options, so other sites may frame it.

   What to do: Send Content-Security-Policy: frame-ancestors 'self' (or a list of trusted origins). X-Frame-Options: SAMEORIGIN covers older browsers.

   50% of Postage & Courier Services peers do this.

4. Priority 4 · Accelerate

   Offscreen images lazy-loaded

   Observed: The homepage had 62 images and none used loading="lazy".

   What to do: Add loading="lazy" to images below the fold. Do not lazy-load the main hero image, because that delays the largest visible element.

   On WordPress: WordPress has added loading="lazy" to images by default since 5.5; check that your theme or a plugin has not removed it.

   44% of Postage & Courier Services peers do this.
