The Best Free Tools for Checking Your AI Visibility

Start With What You Have

Before investing in any paid tools, there are several free resources that can tell you a lot about your AI visibility. Here's our recommended stack for getting started.

1. Bing Webmaster Tools (Free)

This is non-negotiable. Since most AI search engines use Bing's index, Bing Webmaster Tools tells you exactly what AI engines can see. Check your indexing coverage, crawl status, and any errors. bing.com/webmasters

2. Google Rich Results Test (Free)

Test whether your schema markup is valid and complete. Even though AI engines primarily use Bing, valid schema works the same way. search.google.com/test/rich-results

3. Schema.org Validator (Free)

More detailed schema validation than Google's tool. Checks for completeness and correctness. validator.schema.org

4. Manual AI Engine Checks (Free)

The most direct method: just ask AI engines about your product category and see what comes back. Use ChatGPT (free tier), Perplexity (free tier), Gemini (free), and Grok (free on X).

5. EurekaNav Free AEO Audit

We offer a free one-time audit that checks 10 key AEO signals on your website: crawlability, schema markup, content structure, freshness, and more. It gives you a score out of 10 and specific recommendations for improvement.

What to Check First

1. Is your site indexed by Bing? (Bing Webmaster Tools → Coverage)
2. Do you have Product schema? (Rich Results Test)
3. Does your homepage answer "what is [your product]?" in the first paragraph?
4. When you ask ChatGPT about your category, does your tool appear?
5. When was the last time you updated your main product page?

When to Consider Paid Tools

Free methods are great for establishing a baseline and making initial improvements. Once you've implemented the basics and want ongoing monitoring with alerts and trend data, that's when paid tools like AI Sentinel become valuable — they automate the manual checks you'd otherwise need to do weekly.
