Crawler rule groups

Each group targets one or more user-agent tokens and contains its own path rules.

One absolute URL per line

Sitemap URLs should use an absolute https:// or http:// address.

Optional · crawler-specific

The non-standard Host directive is ignored by many major crawlers. Use canonical redirects and canonical tags for hostname consolidation.

Guide compliant crawlers through your website

A robots.txt file communicates crawl preferences to search engine robots and other compliant web crawlers. It can permit broad access, restrict selected paths, create crawler-specific groups, and advertise XML sitemap locations.

The file belongs at the root of a protocol and hostname. For example, rules for https://example.com/ should normally be accessible at https://example.com/robots.txt. Rules on another subdomain or protocol do not automatically apply.

This generator creates groups from your chosen user agents, Allow rules, Disallow rules, and optional crawl delays. It also checks common formatting concerns and provides a practical path tester before you publish the file.

Crawling control is not indexing control

Disallowing a URL prevents compliant crawlers from fetching it, but does not guarantee removal from search results. If a URL is discovered through external links, it may still appear without a descriptive snippet. Use suitable indexing controls and authentication where appropriate.

Complete rule builder

Everything needed to create robots.txt

Build simple or advanced crawler instructions without manually formatting every directive.

Multiple crawler groups

Target all crawlers with an asterisk or create separate groups for Googlebot, Bingbot, or another user-agent token.

Allow and Disallow rules

Add one path per line and generate consistent directives with whitespace and invalid line-break characters removed.

Sitemap discovery

Add one or more absolute XML sitemap URLs as independent directives at the end of the generated file.

Live validation

Identify missing user agents, malformed sitemap addresses, questionable path formats, and crawler-delay compatibility.

Rule path tester

Compare a URL path with the most relevant crawler group and inspect the longest matching Allow or Disallow directive.

Copy or download

Edit the final output if needed, copy it to your clipboard, or download a correctly named robots.txt file.

Three straightforward steps

How to generate a robots.txt file

Configure, verify, and export crawler instructions directly from your browser.

Step 1

Choose crawler rules

Start with a preset or define custom user agents, allowed paths, blocked paths, and crawl delays.

Step 2

Validate and test

Review warnings, add sitemap URLs, and test important paths against the generated crawler groups.

Step 3

Publish at the root

Copy or download robots.txt, upload it to the website root, and verify that the public URL returns the correct file.

Directive reference

Understanding common robots.txt directives

Each directive has a specific role, and crawler support can differ for non-standard instructions.

Directive
Purpose
User-agent
Starts a rule group and identifies the crawler token to which the following Allow and Disallow rules apply.
Disallow
Requests that a compliant crawler not fetch paths matching the specified value. An empty value blocks nothing.
Allow
Explicitly permits a matching path, commonly used to create an exception inside a broader Disallow rule.
Sitemap
Provides an absolute URL for an XML sitemap. Multiple Sitemap directives can be included in one robots.txt file.
Crawl-delay
Requests a delay between crawler requests. Support varies, and Google does not support this robots.txt directive.
Host
A non-standard preferred-host directive supported by some crawlers but ignored by many major search engines.
Common questions

Robots.txt generator FAQ

What is a robots.txt file?

A robots.txt file provides crawl instructions to compliant search engine robots. It is normally placed at the root of a website, such as https://example.com/robots.txt.

Where should I upload robots.txt?

Upload robots.txt to the root of the relevant protocol and hostname so it is available at /robots.txt, for example https://example.com/robots.txt.

Can robots.txt protect private content?

No. Robots.txt is publicly accessible and is not an access-control or security mechanism. Protect confidential content with authentication and server permissions.

Should I add my XML sitemap to robots.txt?

Adding one or more absolute XML sitemap URLs can help crawlers discover them. Sitemap directives are independent of user-agent groups.

Does Google support Crawl-delay?

Google does not support the Crawl-delay directive in robots.txt. Some other crawlers may support it, so verify behavior with each crawler's current documentation.

Does blocking a URL remove it from search results?

Not necessarily. A blocked URL can sometimes remain indexed without a snippet if discovered through links. Use an appropriate noindex method on crawlable pages when removal from search is required.
