What is the Robots.txt Tester?
The Robots.txt Tester is an advanced tool designed to validate the syntax and functionality of your website's robots.txt file. This file provides crucial directives to web crawlers, dictating which areas of your site should be indexed and which should be ignored. The tester allows you to simulate how search engine bots perceive these rules, preventing accidental blocking of important pages. By ensuring your robots.txt is error-free, you can safely guide crawler traffic and optimize your crawl budget.

Frequently Asked Questions
What happens if my robots.txt has syntax errors?
Syntax errors can cause search engine bots to misinterpret your instructions. This could result in critical pages being de-indexed or private directories becoming visible in search results.
Do all bots follow robots.txt directives?
No, robots.txt relies on the honor system. While reputable crawlers (like Googlebot and Bingbot) respect these rules, malicious bots and scrapers typically ignore them entirely.
