📚 How to Generate a Robots.txt File Guide
Everything you need to know to generate and manage robots.txt files like an SEO professional.
What is robots.txt?
A plain-text file at your site root (yoursite.com/robots.txt) that instructs web crawlers which pages to visit or skip. It implements the Robots Exclusion Protocol, the standard since 1994.
How Crawlers Read It
Before visiting your site, Googlebot and other bots fetch robots.txt first. They match their user-agent against the rules and follow the most specific matching block.
robots.txt vs Noindex
robots.txt blocks crawling. Noindex blocks indexing. A URL blocked in robots.txt can still appear in search results if it has external links. For guaranteed removal, use noindex.
Wildcards (* and $)
* matches any sequence of characters. $ anchors to the URL end. Example: /search?* blocks all search variations. /*.pdf$ blocks all PDFs.
Crawl-delay Directive
Instructs bots how many seconds to wait between requests. Google ignores this — use Search Console to adjust Google’s crawl rate. Bing and some other crawlers respect it.
Sitemap Directive
Adding Sitemap: https://yoursite.com/sitemap.xml tells all crawlers where to find your content map. Place it at the bottom, outside any User-agent block.
Most Common Mistakes
Blocking CSS/JS files (prevents rendering), missing the Sitemap directive, blocking images, using Disallow: / accidentally, and forgetting Allow: /wp-admin/admin-ajax.php.
Testing Your File
