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

   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.

   95% of E-Commerce & Marketplaces peers do this. Limit: Only the standard location was requested, once, at the time of the check.

3. Priority 3 · Accelerate

   Modern image formats in use

   Observed: The homepage had 38 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 Next.js: The next/image component serves optimized formats automatically.

   47% of E-Commerce & Marketplaces peers do this.

4. Priority 4 · 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.

   On Next.js: Add it in next.config.js headers().

   70% of E-Commerce & Marketplaces peers do this.
