Pages that look fine can be invisible to Google. A single misconfigured header — one you'd never see just by looking at the page — can wipe a URL from the index entirely. RobotEye surfaces every crawlability signal on any page the moment you click the icon. Find the problem in seconds, not hours.

How RobotEye Works
When you click the RobotEye icon, it reads every signal that tells Google whether it can crawl, index, and follow links on the current page — and shows them all in one place. If two signals are contradicting each other, it tells you which one wins and why. Toggle link annotations and every link on the page gets color-coded instantly, so you can see nofollow, sponsored, and dofollow links without reading a single line of source code.
Features
Know the crawl status of any page at a glance The toolbar icon turns green, yellow, orange, or red based on what it finds. You don't even have to open it to know something's wrong.
Catch the signal most tools miss entirely X-Robots-Tag is an HTTP header that overrides everything else on the page — including your meta tags. RobotEye reads it. Most tools don't.
See exactly which robots.txt rule is blocking a page Not just "blocked" — RobotEye shows you the specific rule that matched and which user-agent it applies to.
Spot canonical mismatches before they cost you If you're not viewing the canonical version of a page, RobotEye tells you immediately and shows you where canonical is actually pointing.
Get warned when your signals contradict each other Header says noindex, meta tag says index? RobotEye flags the conflict and explains which one Google will listen to.
See every link's SEO value without touching DevTools Toggle link annotations and every anchor on the page gets a color-coded underline — green for dofollow, orange for nofollow, purple for sponsored, blue for UGC. Hover any link to see exactly what's set.
