About this robots.txt generator
The robots.txt generator builds the small text file that tells search-engine crawlers which parts of a site they may request. Choose the user-agent rules, the paths to allow or disallow, and a sitemap location, and it assembles a correctly formatted robots.txt to place at the root of your domain.
It is most useful when launching or restructuring a site, where you want crawlers to skip admin, cart, or duplicate paths and to find the sitemap quickly. Remember that robots.txt is guidance for well-behaved crawlers and a publicly readable file — it is not a security control, so genuinely private pages need real access protection.
Common uses
- Create a robots.txt for a new site with sensible crawl rules and a sitemap line.
- Block crawlers from admin, internal search, or duplicate URL paths.
- Point search engines to your sitemap so new pages are discovered faster.
Helpful tips
- Add your sitemap URL so crawlers can find and index pages more efficiently.
- Do not rely on Disallow to hide sensitive pages; it only requests that crawlers skip them.
- After publishing, open /robots.txt on your domain to confirm the rules read as intended.
How to use Robots.txt Generator
- Enter the page, keyword, snippet, robots rule, or preview content you want to check with Robots.txt Generator.
- Make sure the input describes the real page honestly instead of only chasing keywords.
- Run the tool and compare the output with the search result, crawler, social preview, or content workflow you are targeting.
- Edit titles, descriptions, keywords, or rules until they are specific, readable, and aligned with the page content.
- Check the final result on the live page or staging page after publishing because platforms can interpret metadata differently.
Frequently asked questions
Where does the robots.txt file go?
At the root of your domain, reachable at /robots.txt. Crawlers look for it there before fetching other pages.
Can robots.txt keep a page out of search results?
Not reliably. Blocking a URL can stop it being crawled but not always indexed. Use a noindex tag on a crawlable page to keep it out of results.
Is Robots.txt Generator free, and does it work on mobile?
Yes. Robots.txt Generator is free to use on JustBloc with no account or installation, and the page is designed to work on desktop, tablet, and mobile browsers.
