# Fictional sample context

Objective: increase qualified inquiries while understanding paid-search efficiency. Primary metric: qualified leads, defined as a completed inquiry with an email and business need that passes the sample qualification rule. Count at most one lead per eligible session; the sample rollup is deduplicated. These are leads, not new customers or sales.

Periods: October 5–11 and October 12–18, 2026, inclusive, UTC; both complete seven-day windows. Same qualification and session attribution definitions in both periods. Each session belongs to exactly one listed channel. No missing channels in this sample. The CSV is a fictional, manually reconciled weekly rollup, not a live platform export. Ad spend means paid-search media spend only; email and organic labor/tool costs are excluded. Currency USD. No revenue, acquisition cost, margin, or incrementality data is supplied.

Changes: a new paid-search landing-page variant went live October 12. No experiment assignment, user-level data, query mix, device mix, or quality follow-up is provided. This timing is a hypothesis lead, not proof that the variant caused the change. No known tracking or qualification changes in this fictional case.

Reviewer: marketing lead. Capacity: two hours this week. No named action owners or fixed review appointment. Prepare a draft in the current chat only.
