Free GEO Tools You Run Yourself
Yogoo AI’s free GEO tools are Markdown files you drop into Claude Code, Cursor, or a ChatGPT chat. Your assistant reads the file and does the generative engine optimization work on your own site, then hands back something you can use the same day. You don’t need to sign up to download them. For a manual version of the first check, see how to check if ChatGPT can read your website: a five-minute curl test you can run before reaching for a skill.
What are GEO tools?
GEO tools, short for generative engine optimization tools, help AI answer engines read a website and quote it. The engines in question are ChatGPT, Claude, Perplexity, Gemini, and Google AI Overviews. It’s a different field from geographic or GIS software, which shares the name.
Most GEO tools, sometimes sold as generative engine optimization software, do one of two jobs. Some change your site: they fix what AI crawlers can’t read and reshape content so an engine can lift a clean passage. Others measure the result. They track AI mentions of your brand by asking AI engines the questions your buyers ask and counting how often your business comes up. The skills on this page do the first job. The Yogoo Score does the second.
How do the skills work?
- Get the file. Download or copy any skill below. It’s plain markdown.
- Give it to your AI. Drop it into Claude Code or Cursor, or paste it into a ChatGPT or Claude chat.
- Run it on your site. The skill walks your assistant through each check and hands back the deliverable.
There’s no new tool to learn, because the skill runs inside the AI assistant you already use.
The three free GEO tools
GEO Site Audit
Checks your AI crawlability the way AI crawlers actually read your site: JavaScript shell, robots.txt, metadata, entity clarity. Returns a fix list ordered by impact and effort.
Once you’ve got your fix list, see how to improve your AI visibility for the wider playbook the fixes fit into.
llms.txt Generator
This llms.txt generator reads your site and drafts a correct llms.txt file: a curated map of your key pages in the llmstxt.org format, ready to place at your web root. Not sure how to create llms.txt by hand? This skill does it for you.
Citation-Ready Content Check
Runs an AI citation content check on a draft or URL against 8 citation heuristics, such as answer-first openings and sourced facts. It then strengthens only the weak parts and leaves your own voice alone.
Which skill should you run first?
| If this is your situation | Start with |
|---|---|
| You don’t know whether AI crawlers can read your site | GEO Site Audit |
| Crawlers can read it, but you’ve never written an llms.txt file | llms.txt Generator |
| You have a page or draft you want AI answers to quote | Citation-Ready Content Check |
If you’re not sure which of these GEO tools to start with, run the audit. If AI crawlers get an empty page from your site, fix that first, because an llms.txt file and better content both point at pages the crawlers still can’t read.
What can’t the skills tell you?
These GEO tools make your site easier to cite. They can’t tell you whether AI answers actually name you. That takes measurement, and it’s what the Yogoo Score, Yogoo AI’s free AI visibility tool, is for.
The Yogoo Score is the share of AI answers in your market that name or link your business. It always shows its counts, like 61 of 480 answers (12.7%), and each engine available for your market gets its own line. Yogoo AI asks your market’s questions every day, on every plan. Everyone in a measured market gets their score with its counts, a sample of the questions buyers ask AI, and the full rivals table at no cost. Paid plans add more trackers and workflow tools, not a different number.
The score needs a free account, and no card is required. You tell Yogoo AI your business and your market. If it already measures that market, your score shows from the first answer it collects, and the page marks it “Still collecting” until 28 days of answers are in.
If Yogoo AI doesn’t cover your market, the page says “We don’t measure your market yet.” It shows the market you asked for and the date your request went for review, and Yogoo AI emails you if it adds the market. That’s a decision about where Yogoo AI collects answers. It says nothing about your site.
To see what your fixes changed, compare two dated windows, like the 28 days ending the day your fixes shipped against the 28 days ending four weeks later. Both windows need to start on or after 3 October 2026. Yogoo AI corrected how the score is calculated that day, and scores from either side of it measure different things. How Yogoo AI measures AI visibility covers the full method.
These GEO tools are versioned and re-verified as AI engines change, and the “last verified” date on each one is real. Something broken or missing? Tell us.
