The "Robots.txt Test" tool from TeckBlaze analyzes the /robots.txt file at the domain root in real time. You enter a URL above, we fetch the page exactly as Googlebot would, isolate the tested element, compare it to 2026 best practices, and tell you in plain words whether it passes, needs work, or is critical.
Why robots.txt test still matters in 2026
The robots.txt file and related directives control what Google crawls and what it ignores. A misplaced Disallow rule can block strategic pages.
The newer reason: AI answer engines and link previews
Many owners unknowingly block AI bots in robots.txt. Result: invisible in ChatGPT, Claude and Perplexity. Audit your rules before being surprised by missing traffic.
Common mistakes worth checking
Disallow rule too broad, blocking by accident.
AI bots explicitly forbidden (loss of ChatGPT/Perplexity visibility).
No sitemap reference in robots.txt.
Wrong casing in directives (mis-spelled User-Agent).
File returning a 404 or 500.
How do I fix it?
Fixing the /robots.txt file at the domain root usually takes minutes once you know where to look. Below: the code example, where to edit it based on your stack, the usual causes, and the best practices that keep the issue away.
