What is Robots.txt?
A text file at the root of a website that instructs search engine crawlers which pages or sections should not be crawled.
Understanding Robots.txt
The robots.txt file uses the Robots Exclusion Protocol to communicate with web crawlers. It can specify rules for all bots or target specific crawlers (like Googlebot or Bingbot), and it typically includes a reference to your XML sitemap. Important to understand: robots.txt prevents crawling, not indexing. If other sites link to a page blocked by robots.txt, Google may still index the URL based on external signals. For preventing indexing, use noindex meta tags instead. Common uses include blocking admin areas, duplicate content paths, and resource-heavy sections that waste crawl budget. Keyword Kick's free robots.txt generator helps you create properly formatted files with best-practice configurations.
Why It Matters
A misconfigured robots.txt can accidentally block search engines from crawling your most important pages, or waste crawl budget by allowing access to low-value sections of your site.

Frequently Asked Questions
Can robots.txt prevent a page from appearing in search results?
Not reliably. Robots.txt blocks crawling, but if external links point to a blocked page, Google may still index the URL using anchor text from those links. To truly prevent indexing, use a noindex meta tag and allow crawling so the directive can be read.
Do all search engines respect robots.txt?
Major search engines like Google, Bing, and Yahoo respect robots.txt directives. However, malicious bots and scrapers typically ignore it. Robots.txt is a protocol based on cooperation, not a security measure — never use it to protect sensitive content.
