Robots.txt Generator

A robots.txt file is five lines of plain text, and one typo can hide your whole site from Google. This free robots txt generator builds the file from checkboxes and fields instead: tick Allow all crawlers, list the paths you want blocked, and the output pane writes valid directives as you type. Developers use it to create robots txt file output for new sites, and SEO folks reach for it after a staging folder leaks into search results. One real case: an agency shipped a client site with /admin and /api wide open to bots, pasted those two paths into the Disallow box here, and had a clean custom robots txt live in under two minutes.

Why Robots.txt Generator

Common questions

Does the Robots.txt Generator handle AI crawlers like GPTBot?
Yes. One checkbox appends a block section covering GPTBot, ClaudeBot, Google-Extended, and CCBot, each with its own User-agent group and a Disallow rule for the whole site. You can leave regular search bots untouched while shutting out model training crawlers.
Where does my finished robots.txt file have to live?
At the root of the host, nowhere else. Crawlers request /robots.txt on each hostname, so every subdomain needs its own copy. After you create robots txt online here, upload the result so it resolves at https://yourdomain.com/robots.txt.
Can I block only certain folders in the generated robots.txt?
Yes, that's the whole point of the Disallow paths box. Enter /admin, /api, or any prefix, one per line, and each becomes its own Disallow line. Combined with Allow for the root, this custom robots txt generator setup leaves everything open except what you name.
What does the Crawl-delay field in this robot generator do?
It adds a Crawl-delay line with the number of seconds you enter. Bing and Yandex respect it as a pause between requests, while Googlebot ignores the directive entirely. Leave it empty unless a specific bot is genuinely overloading your server.
Is the Sitemap line in robots.txt actually necessary?
It's optional but cheap insurance. The Sitemap declaration tells any crawler where your URL list lives, including ones you never registered with. The tool appends it automatically whenever the Sitemap URL field is filled in.
Why use a robots txt generator online instead of writing the file by hand?
Because the syntax fails silently. A missing colon or a Disallow typed as Dissallow doesn't throw an error anywhere, crawlers just skip the line. This robot txt file generator writes each directive for you, so what you copy is always parseable.
Will Disallow rules from this generator remove pages from Google?
Not by themselves. Disallow stops crawling, not indexing, so a blocked URL can still appear in results if other sites link to it. To deindex a page, allow crawling and add a noindex meta tag on the page instead.
After I upload the generated robots.txt, what's the quickest way to verify it?
Point the Robots.txt Reader at your domain. It fetches the live file and lays out every group by crawler, so you can confirm the rules you built here arrived at the server intact.
Can this build a robots txt file for a WordPress site?
Yes. WordPress serves a virtual robots.txt by default, and this robots txt generator wordpress owners can use to replace it: tick Allow all, add Disallow lines for /wp-admin/ or staging folders, and paste the result via an SEO plugin or a static file at the root. The generated robots txt file stays valid whether WordPress or a plugin ends up serving it.
Does it work as a blogger robots txt generator?
It does, with one caveat. Blogger has its own Custom robots.txt field in Settings, so you paste text into that box rather than uploading a file. Build the rules here as a blogger robots txt generator would, then copy the output into Blogger's setting. Keep the Disallow paths matched to Blogger's /search and label URLs.
How do I use it as a custom robots txt generator for blogger blogs?
Same flow, one paste target. Configure Allow and Disallow above, and this custom robots txt generator for blogger writes the directives; then drop them into the Custom robots.txt box in Blogger's crawler settings. Since Blogger won't let you upload a file, the copy button is doing the real work here.
Is there a sample robots txt I can start from?
Yes. The tool opens pre-filled, so the output pane already shows a sample robots txt: a User-agent line, an Allow, a few Disallow paths, and a Sitemap line. Edit those defaults and it becomes yours. Reading that sample robots txt file first is the fastest way to learn what each directive does.
Can I copy a robots txt example straight from the output?
That's exactly what the output pane is. It rewrites a live robots txt example as you toggle rules, so switch Block AI crawlers on and you get a ready GPTBot and ClaudeBot block to copy, or leave it off for a standard open file. Nothing is hidden behind a paywall.
What does a robots txt file example look like here?
It reads top to bottom: a User-agent group, Allow and Disallow lines, an optional Crawl-delay, then a Sitemap declaration. That robots txt file example is generated from your settings, so tweaking a checkbox changes it in place. If you only wanted a sample robots txt file to study, the starting state is that reference.
Does robots txt seo affect my rankings directly?
Not directly. robots txt seo is about crawl control, so the file steers bots away from low-value paths and toward pages that matter, rather than boosting any single page. Remember a Disallow stops crawling, not indexing, so it won't remove a URL already in Google. Use it to shape where crawl budget goes.
Is this an seo robots txt maker for crawl control?
Yes. As an seo robots txt maker it writes the Disallow and Sitemap lines that keep admin, API, and staging folders out of crawl paths while your real pages stay open. The syntax fails silently when hand-typed, so having the tool write each line means what you copy is always parseable.
Can I create robots txt file online here and build robots txt without an editor?
Yes. You build robots txt in the form, the output pane rewrites the file as you type, and one button copies it, so you create robots txt file online without touching a text editor. Upload the copied robots txt to your domain root so it answers at yoursite.com/robots.txt, which is the only place crawlers look.
What is the robots txt code this generator writes?
Plain directives, nothing exotic: User-agent, Allow, Disallow, Crawl-delay, and Sitemap lines. The robots txt code mirrors what the major crawlers parse, so a robots txt file built here works the same in Googlebot and Bingbot. Read it before you ship, since a stray Disallow is easy to miss.
