Why it matters
robots.txt tells search engines and AI crawlers what they may read. Without it you can't keep them out of pages like /admin or /api.
How to check it yourself
Visit yoursite.com/robots.txt. A 404 or your homepage coming back means you don't have one.
What the fix involves
Add a robots.txt that allows public pages, disallows private areas like /api and /admin, and points to your sitemap.
How vibeliq checks it
We load your page the way a visitor's browser would, read what your server sends back, and look at a short list of well-known addresses on your site. If this turns up, your report explains it in plain English and gives you a prompt, written for Claude Code, Cursor, Lovable or whatever built your site, that fixes it in your actual codebase.
