vfedorov.comQuestions 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 We do not publish another brand's diagnostics
