Questions we get

Is this SEO?

No. SEO measures your position in a list of links. We measure whether an assistant names you when a shopper asks what to buy. A brand can rank first on Google and never appear in the answer

How accurate is this?

Twenty-five passes per question across five assistants, through official APIs. We report patterns, and print raw counts where a rate would mislead

Are the brands in your reports customers?

No. Every brand is measured from public AI answers. We do not publish another brand's diagnostics
