What is a robots.txt file and do I need one?

A robots.txt file lives at the root of your site and tells search engine crawlers which pages or folders they may or may not crawl. It is not required, but it is recommended: it helps you block private or duplicate areas, control crawl budget, and point crawlers to your sitemap.

What is robots.txt

What a robots.txt file does and why it matters in 2026

A robots.txt generator creates the small text file that lives at the root of your site and tells search engine crawlers which areas they may or may not access. It's the first file most crawlers request, so getting it right is a foundational technical SEO step.

Robots.txt is ideal for keeping crawlers out of admin areas, duplicate URLs, and low-value pages, and for pointing them to your sitemap. It does not, however, control indexing — for that you need a noindex tag. After setting up robots.txt, make sure your important pages are discoverable with a fresh XML sitemap and well optimized with our keyword density checker.

Controls which pages and folders crawlers can access
Helps manage crawl budget on large websites
Keeps admin, cart, and duplicate URLs out of the crawl
Points search engines to your sitemap
Can ask AI crawlers not to use your content for training
Should never be used alone to hide truly private content

How to set up robots.txt for WordPress (and block AI bots)

For WordPress, the safe default is to disallow /wp-admin/ while allowing admin-ajax.php, then adding your sitemap. Our WordPress preset does exactly this in one click — no need to memorize the syntax.

Increasingly, site owners also want to stop AI crawlers from scraping their content for training. Reputable AI bots honor robots.txt, so toggling GPTBot, ClaudeBot, Google-Extended and others adds the right disallow blocks automatically. Pair this with schema markup for a complete technical setup.

Use the WordPress preset for correct /wp-admin/ handling
Always add your sitemap URL for faster discovery
Block AI crawlers in one click if you don't want AI training use
Avoid blocking CSS/JS folders — Google needs them to render pages
Never rely on robots.txt to hide sensitive data — use auth or noindex
Test every robots.txt in Google Search Console before trusting it
