   Meta description written

   Observed: The homepage had no meta description.

   Why it matters: Search engines often use it for the snippet under your link, so a clear description can improve click-through.

   What to do: Write a short, specific description of the page for people, not a list of keywords.

   95% of News & Media peers do this. Limit: Based on the homepage HTML delivered to an automated client; scripts that run later were not executed.

   Modern image formats in use

   DMARC policy enforces quarantine or reject

4. Priority 4 · Accelerate

   Offscreen images lazy-loaded

   Observed: The homepage had 32 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.

   72% of News & Media peers do this.
