Priority fixes for resy.com
Ordered by impact and by how common each practice is among peers.
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.
87% of Events & Online Ticketing peers do this. Limit: Only the standard location was requested, once, at the time of the check.

Priority 2 · Enable

What to do: Generate an XML sitemap of canonical URLs, reference it in robots.txt and submit it in Google Search Console.
