What the Robots.txt Generator does

A robots.txt file sits at the root of your domain and tells crawlers which parts of your site they may or may not visit. Getting it right matters: one stray Disallow can accidentally hide your whole site from Google, while a missing rule can let unwanted bots hammer your pages. This tool builds a correctly formatted robots.txt through a visual form, so you never have to remember the exact syntax of User-agent, Allow and Disallow lines.

It is aimed at site owners, developers and SEO practitioners who want a quick, valid file without typos. You choose a default behaviour, add specific rules, optionally set a crawl delay and a sitemap link, and the live preview shows the finished file ready to copy or download.

How to use it

Begin with Default Behaviour: tick Allow all bots to welcome every crawler, or Block all bots to keep everyone out (useful for staging sites). Then add granular rules in the Add Rule section by entering a user-agent such as * or Googlebot, choosing Allow or Disallow, and typing a path like /admin/. Each rule you add appears in a list you can remove individually.

For common scenarios, click a preset such as Block AI Scrapers, Allow Google Only, Block Bad Bots or WordPress Standard to drop in a ready-made rule set. Add a crawl-delay in seconds if you want to slow down aggressive bots, paste your sitemap URL so crawlers can find it, then click Copy to grab the text or Download to save a robots.txt file directly.

Tips and notes

Robots.txt is a request, not a hard lock. Well-behaved crawlers like Googlebot honour it, but malicious bots can ignore it, so never rely on it to protect private data; use authentication for that. Place the finished file at the root of your domain (for example https://example.com/robots.txt) for it to take effect.

Be careful with Disallow: / under User-agent: *, as it blocks your entire site from search engines. Always include your sitemap line to help crawlers discover your pages, and remember that the AI-scraper and bad-bot presets only deter crawlers that choose to respect the file.

Frequently Asked Questions

Where do I put the generated robots.txt file?▼
Place it at the root of your domain so it is reachable at yourdomain.com/robots.txt. Crawlers only look for it in that exact location.
Does this tool send my rules to a server?▼
No. The file is generated entirely in your browser from the form, and Copy and Download both work locally without any upload.
Will blocking bots in robots.txt actually stop them?▼
It stops well-behaved crawlers like Googlebot that choose to obey the file. Malicious or rogue bots can ignore it, so do not use robots.txt to protect sensitive content.
What do the presets do?▼
They load ready-made rule sets for common needs, such as blocking AI scrapers like GPTBot and CCBot, allowing only Google, blocking known bad SEO bots, or applying standard WordPress paths.
What is the Crawl-delay option for?▼
It asks crawlers to wait a set number of seconds between requests to reduce server load. Note that Google ignores crawl-delay, though some other crawlers honour it.
Is it free to use?▼
Yes, the generator is completely free with no sign-up and no limit on how many files you create.
