What is a Robots.txt File?
A robots.txt is a plain text file based on the standard **Robots Exclusion Protocol**. Placed inside your website's primary directory, it instructs web robot crawlers which sections of your site's architecture can be loaded and whitelisted, and which sections are blocked from scraping actions.
Search spiders (like Google's *Googlebot* and Bing's *Bingbot*) consult your robots.txt file before exploring other routes on your server. Without a valid configuration, indexing software consumes server memory indexing transient caches, sorting widgets, database logs, or backend checkouts, hurting your domain's indexing budget.
How Robots.txt Directives Work
A standard robots.txt is written using simple block assignments. Here are the core directives supported by almost all major search engines:
User-agent:
Specifies the name of the automated crawler program you are writing rules for. Adding * matches all robots universally.
Disallow:
Defines target folders, paths, or single routes that search engine robots are forbidden from crawling.
Allow:
Tells crawlers they can access a nested subdirectory or resource even if the parent structure is currently disallowed.
Crawl-delay:
Instructs indexers to wait a specific number of seconds between successive page loads to protect server databases.
Standard Robots.txt Code Examples
Example 1: Allow All Crawlers Universally (Recommended Default)
User-agent: * Allow: / Sitemap: https://yourdomain.com/sitemap.xml
Example 2: Block Crawlers From Speculative or Admin Routes
User-agent: * Disallow: /admin/ Disallow: /checkout/ Disallow: /tmp/ Disallow: /search?q= Sitemap: https://yourdomain.com/sitemap.xml
Example 3: Block Entire Website (Only for Staging or Sandbox Sites)
User-agent: * Disallow: /
Robots.txt Best Practices
- Place file strictly at the system root: Bots search for your rules at exactly
https://yourdomain.com/robots.txt. Placing it inside other folders (e.g.https://yourdomain.com/assets/robots.txt) makes it completely ignored. - Always include your Sitemap URL: Pointing bots toward sitemap directories helps crawl programs map out fresh content pages immediately upon discovery.
- Each path directive should begin with /: The system identifies standard directories beginning with forward slashes.
- Never use robots.txt to hide sensitive personal information: Since robots.txt is a completely public page open for users to view in browser tabs, do not paste names of private directories inside your exclusions as it calls unnecessary attention to them.
