Free AI SEO Tools
Check whether AI crawlers can read your site, whether your firewall lets them in, and give language models a map of your key pages. Free, with no sign-up required. Guides that put the results to work are on the Ranking Atlas blog.
How to Use These Free Tools
- Step Step 1: Start with the robots.txt checker: it is the first file an AI crawler reads.
- Step Step 2: Enter your website address and run the check. Results take a few seconds.
- Step Step 3: Fix anything it finds, then run the next check in the list.
Check AI Crawler Access
Three checks, in the order to run them. A block at either of the first two stops AI engines reaching your pages, whatever else you fix.
-
robots.txt Checker
See which AI search, answer and training crawlers your robots.txt lets in, with the exact rule behind each result and the lines to fix it.
Check robots.txt -
AI Bot Block Test
Find out whether your firewall or CDN turns ChatGPT, Claude, Perplexity and other AI crawlers away, even when robots.txt allows them.
Test AI bots -
llms.txt Generator
Build an llms.txt file for your website from its sitemap and page titles, ready to edit, copy or download.
Build llms.txt
What Do These Free AI SEO Tools Check?
They check access, the step every other part of AI search depends on. An AI engine can only cite a page its crawler can fetch, and two things decide that: the rules in your robots.txt and the bot settings in your firewall or CDN. The third tool builds an llms.txt file, an optional map of your key pages.
The robots.txt checker reads your file the way the crawlers do and names the rule behind each result. The AI bot block test requests your page as each crawler and compares what it gets with an ordinary browser. The llms.txt generator drafts the file from your sitemap.
Which Tool Should You Run First?
Start with the robots.txt checker, because robots.txt is the first file a well-behaved crawler reads. If it lets the AI search crawlers in, run the AI bot block test to confirm your firewall agrees. Build an llms.txt file last: it only helps once crawlers can reach your pages.
What Can’t a Technical Check Tell You?
Whether AI engines recommend you. Access makes a citation possible; it does not earn one. Engines name the brands that independent sources corroborate, so visibility depends on coverage, comparisons and reviews elsewhere, and on measuring a fixed set of buyer prompts over time to see whether the work is landing.
Our guide to getting cited by ChatGPT covers that work in order of leverage. To track the result, the AI visibility measurement method is free to use, and the paid trackers that automate it are compared in our guide to AI visibility tools.
Frequently Asked Questions
Are the Tools Really Free?
Yes. All three are free, with no sign-up and no email address. Each one reads only public files and pages, the same ones any crawler reads, and we don’t save the addresses you enter.
Do I Need to Be Technical to Use Them?
No. Enter your website address and each tool explains its result in plain English, with the lines to copy where a fix is needed. Changing robots.txt or firewall settings may need whoever manages your website or CDN.
Does llms.txt Help You Rank in AI Search?
No AI engine has confirmed that it reads llms.txt, so treat it as a tidy extra rather than a ranking lever. It takes minutes to publish and does no harm, which is why it comes last in the order above.
