   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.

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