Measure outcome page changes

Deprecated: use business.outcome-page-changes.measure.v2 (business_outcome_page_changes_measure_v2), which also measures in a Shopify shop; this version leaves out a Shopify shop, measuring in the first chosen Google Analytics property or Vercel project, so an organization that reads only a Shopify shop answers each change not_connected. Measure how AI-assistant visits to sets of changed pages moved against the rest of the site's AI-assistant visits, before and after each change. Each change names its pages (URLs or paths) and the days the change went live between; the answer compares up to 56 days before with up to 56 days after and reports the relative change with an approximate 90% range, or says why it cannot (not connected, too early, too few visits, nothing to compare with). It measures a provider's visit counts only and changes nothing; it is sent as a write only because each change is an object.
