When answers replace result pages, position stops existing. The metric that matters is share of answers: of the times an engine answered a question in your category, how often were you a cited source?
Our panel method is published here in full. A fixed prompt set per category, run weekly across engines, with citations logged and deduplicated by domain.
You cannot rank number one in a paragraph. You can only be the source it trusts.
The worked example tracks three brands over twelve weeks, including the week one of them shipped answer-first rewrites and moved from 9% to 31% share.
