          Why free

## We would rather be judged on tools that work than on a brochure

Every one of these was built because we needed it for client work or for a study. Publishing them costs us nothing and gives you a way to check our reasoning against your own site before you ever speak to us.

If a tool tells you your site is fine and you do not need an agency, that is a correct answer and we are content for you to act on it.

          The connection

## These tools produce our research

The crawler checker generated our [506-domain study on AI crawler blocking](https://moxseo.com/ai-crawler-blocking-study/). The extractability checker generated the [243-site study on whether AI can quote you](https://moxseo.com/ai-answer-extractability-study/).

A tool nobody has run at scale is an opinion with a form field. Ours have been run across thousands of real sites, and the raw data is [published openly](https://moxseo.com/research/) so you can check the output yourself.

        If something turns up

## Finding the problem is the easy half

If a tool surfaces technical debt or AI extraction blockers you would rather not fix yourself, that is what we are for.
