Robots.txt Generator

How to Use

• Choose generate or validate mode. Use `Generate robots.txt` to build a new file from structured inputs, or switch to `Validate existing robots.txt` if you already have a draft or live file.
• Enter crawl rules and sitemap details. Add the public site URL, your main `User-agent`, one allow or disallow path per line, and any extra bot-specific sections or sitemap URLs you need.
• Create the report. Run the tool to build the final file, review the parsed crawler groups, and inspect warnings for risky patterns such as blocked assets or missing absolute sitemap URLs.
• Publish only after review. Copy the output when the rules reflect your real crawl intent, then place the file at `/robots.txt` on the live hostname and test the deployed URL.

Directive Strategy and Common Mistakes

Practical Use Cases

On a WordPress site, a common rule is to disallow `/wp-admin/` while allowing `/wp-admin/admin-ajax.php`, because that keeps most admin screens out of crawl paths without blocking a frequently needed endpoint. On an ecommerce site, robots.txt is often used to limit crawl waste from cart pages, account areas, checkout flows, faceted navigation, or internal result pages generated by sort and filter parameters. On a staging site, a temporary site-wide disallow can be reasonable, but it should be removed before launch and rechecked after DNS or deployment changes.

The validator is also useful when inheriting a file from another team. It can catch subtle issues like a non-absolute sitemap line, a malformed `Host` directive, or a `Crawl-delay` value written as plain text instead of a number. Those details matter because a robots.txt file is simple, but production mistakes are often simple too.

What Robots.txt Does Not Do

Robots.txt is a crawl-management file, not an access-control system and not a guaranteed deindexing switch. If a URL is blocked but linked from elsewhere, search engines may still show that URL in search results without crawling its full content. Sensitive documents, admin tools, and private environments should be protected with authentication, network restrictions, or explicit noindex strategies on crawlable pages. That distinction is one of the most common misunderstandings in technical SEO conversations.
