What KPIs measure AEO?

The core AEO KPIs are citation rate, AI share of voice versus competitors, answer accuracy (does the engine describe you correctly), and referral traffic from AI engines like Perplexity.

What is AI share of voice?

AI share of voice, sometimes called share of model, is how often your brand is cited across answer engines relative to competitors for the same set of prompts.

Prompt each engine with 10-15 real customer questions on a schedule, record which sources are cited, and track your citation rate and share of voice over time. Tools like Profound, Similarweb, and HubSpot AEO automate this.
