# VisibilityBench > Independent testing of AI search visibility and answer engine optimization (AEO) tools. We buy our own subscriptions, run each tool on a real small business website for a fixed test period, and publish dashboard screenshots, tracked prompts, and before/after visibility data. Affiliate-funded, with disclosures on every page that contains an affiliate link. ## Key pages - [Five AEO tools compared on published pricing](https://visibilitybench.com/articles/aeo-tools-compared.html): A pre-testing comparison of Airefs, SE Ranking, Otterly, AIclicks, and Promptwatch, documenting where published pricing sources contradict each other, and disclosing our applied-for affiliate interest in Airefs. - [How to check if ChatGPT recommends your business, free, in 10 minutes](https://visibilitybench.com/articles/check-chatgpt-recommendations.html): A free manual method for a small business owner to test whether ChatGPT, Perplexity, and Google AI Overviews recommend their business, plus the five things the free method cannot measure. - [About](https://visibilitybench.com/about.html): Testing methodology and why the site is published under a brand rather than a byline. - [Affiliate disclosure](https://visibilitybench.com/disclosure.html): Programs we participate in and how commissions are kept away from verdicts. ## Methodology - Self-purchased subscriptions for every hands-on test - Tests run on operating small business websites, described generically to protect the businesses - Baseline captured before any changes; every change logged - Verdicts link to screenshots or logged data points ## Status The site launched in July 2026.
