Formula or logic used
Robots Exclusion Standard Syntax
Robots.txt adheres to the Robots Exclusion Protocol (RFC 9309) with User-agent, Disallow, Allow, and Sitemap directives parsed sequentially.
`User-agent: *` defines global fallback rules for all crawlers unless a specific user-agent match exists.`Disallow: /path/` blocks crawlers from accessing URLs starting with that prefix.`Allow: /path/public/` overrides a parent Disallow rule for specific subdirectories.Wildcard `*` matches zero or more characters; `$` anchors the pattern to the end of the URL string.`Sitemap: https://yoursite.com/sitemap.xml` provides search engines with your indexable map.
Examples
Example 1: Standard Production Website
Protects sensitive customer and administrative areas while stopping AI data scraping.
Example 2: Staging / Development Environment
Signals all search bots to stay away, preventing staging duplicate content penalties.
Common use cases
AI Web Scraper Management
Control whether OpenAI (GPTBot), Anthropic (ClaudeBot), or Common Crawl ingest your proprietary content.
Internal Search Result Blocking
Block faceted filters and internal search pages (`/*?s=*`) to conserve Googlebot crawl budget.
WordPress Admin Protection
Block `/wp-admin/` while ensuring `/wp-admin/admin-ajax.php` remains accessible.
Sitemap Discovery Configuration

Frequently asked questions
Does robots.txt prevent a page from appearing in Google Search?
Not necessarily. If other websites link to the blocked URL, Google may still index the page URL without content snippet. To guarantee complete exclusion from search results, use a `<meta name="robots" content="noindex">` tag on the page itself.
Where should the robots.txt file be uploaded?
Robots.txt must be placed in the root directory of your website domain (e.g. `https://yoursite.com/robots.txt`). It will not be recognized if placed in a subdirectory.
Is robots.txt case-sensitive?
Yes. Path directives in robots.txt are case-sensitive. `Disallow: /admin/` will not block requests to `/Admin/` or `/ADMIN/`.
Can I block Google from crawling CSS and JavaScript files?
No! Google explicitly requires access to CSS and JavaScript to render and evaluate your website's layout, mobile-friendliness, and Core Web Vitals. Blocking assets can cause severe ranking drops.
