What is a robots.txt file?

A robots.txt file is a plain text file placed in a website's root directory that provides instructions to web crawlers (such as Googlebot and Bingbot) about which URLs or directories they are allowed or disallowed to crawl.

Where should I place the robots.txt file on my server?

The robots.txt file must be uploaded to the root directory of your domain (e.g., https://example.com/robots.txt). Search engine crawlers look specifically for this file at the root level.

Does robots.txt prevent pages from being indexed?

Not necessarily. Disallowing a page in robots.txt prevents search engines from crawling it, but if other external websites link to that URL, search engines may still index the link. To prevent indexing completely, use a 'noindex' meta tag.

Why Every Website Needs a Properly Configured Robots.txt File

A robots.txt file is a foundational text document placed at the root of a website server (e.g., https://example.com/robots.txt). It serves as the primary communication protocol between webmasters and search engine crawlers (such as Googlebot, Bingbot, and DuckDuckGo Bot).

By defining explicit Allow and Disallow directives, a robots.txt file prevents search engine bots from crawling internal admin panels, temporary staging folders, CGI scripts, or duplicate search parameter URLs—thereby optimizing your domain's Search Engine Crawl Budget. Our free Online Robots.txt Generator builds clean, Google-compliant crawler files instantly.

Core Directives and Syntax Explained

Understanding standard Robots Exclusion Protocol directives:

User-agent: Specifies which search engine bot the directive applies to. Using User-agent: * applies instructions globally to all web crawlers.
Disallow: Instructs crawlers NOT to access specific directories or file paths (e.g., Disallow: /admin/).
Allow: Explicitly permits access to a specific subfolder within an otherwise disallowed directory (e.g., Allow: /admin/public-assets/).
Sitemap: Provides search engines with the exact absolute URL of your XML sitemap index (e.g., Sitemap: https://example.com/sitemap.xml).
