# Diaz AEO > Independent Agentic Engine Optimization (AEO) agency. We measure what ChatGPT, Gemini, Perplexity and Google's AI Overview say about a business and which sources they cite, then fix what is wrong. Owned by Diaz Agents LLC, run by Pablo Diaz. ## What we sell - Free AI visibility audit - first 10 launch clients. Report inside 48 hours. - AI visibility audit - $100, money-back guarantee. - AEO Fix Sprint - $2,000. We implement the fixes. 60-day guarantee: the number of prompts that cite your domain at least doubles against the baseline measured on audit day, or you are refunded. ## How a measurement works - 15 customer prompts, frozen on the audit date, on 4 engines: ChatGPT, Gemini, Perplexity, Google AI Overview (60 answers). - The scored unit is the prompt: a prompt counts when at least one measured engine cites the client's own domain in that answer's sources. - Baseline at audit time; the same prompts and locale re-run once at day 60. - Intake is a URL. No analytics, no Search Console, no access of any kind. - Engines that error are retried, then dropped from baseline and re-run alike, and the target is recomputed rather than argued. - We do not measure Grok, and Claude only appears as a diagnostic column on paid sprints. Neither counts toward the guarantee. ## What we do not claim - No traffic figures and no lift percentages: we never see the client's analytics, so we could not defend one. - No promise of a first-place ranking or a perfect score. ## Pages - [AI visibility audit](https://rankaseo.live/): We ask ChatGPT, Gemini, Perplexity and Google's AI answers the questions your buyers ask, record who gets cited, and hand you the fixes. Free audit. - [What is AEO (Agentic Engine Optimization)?](https://rankaseo.live/what-is-aeo): AEO is earning mentions and citations inside AI answers, not just ranking in a list of links.
