Priority fixes for picresize.com

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

1. 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.

   93% of Web Tools peers do this. Limit: Only the standard location was requested, once, at the time of the check.

2. Priority 2 · Accelerate

   No render-blocking scripts in <head>

   Observed: The homepage <head> loaded 1 external script 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.

   69% of Web Tools peers do this.

3. Priority 3 · Harden

   HSTS kept for at least a year

   Observed: Strict-Transport-Security was sent with a max-age of 126 days, below the one-year benchmark.

   What to do: Send Strict-Transport-Security on HTTPS responses. Start with a short max-age (for example 300 seconds), confirm every subdomain works over HTTPS, then raise it in steps to 31536000. Add includeSubDomains only when all subdomains are HTTPS. HSTS preload is optional and hard to undo; hstspreload.org itself does not recommend it by default.

   30% of Web Tools peers do this.

4. Priority 4 · Accelerate

   Offscreen images lazy-loaded

   Observed: The homepage had 6 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.

   59% of Web Tools peers do this.
