AI Snapshot
A Google Ads Conversion Lift study usually needs eligible campaign access, a meaningful conversion action, enough volume for Study Power, a documented holdout, adequate duration for conversion lag, and clean conversion tracking before launch.
What Requirements Matter Before You Request a Study
The best time to think about Conversion Lift requirements is before the campaign is already live and politically difficult to touch. The practical question is whether the account can support a clean holdout experiment that measures causal conversions, not just attributed conversions.
Use the main Google Ads Conversion Lift guide for the calculator and methodology, then use this checklist to prepare the account.
Campaign Eligibility and Google Rep Support
Google says Conversion Lift availability depends on campaign type and account access. User-based Conversion Lift is commonly discussed for Video, Discovery, and Demand Gen, while other campaign types may require Google account-team support. Confirm the exact eligibility path before promising a launch date.
Conversion Action Requirements
Choose the conversion action that best represents business value. For ecommerce, that may be purchases or purchase value. For B2B, it may be qualified lead submission, booked meeting, opportunity creation, or an offline conversion imported from CRM.
- Primary action: The event that the study should judge.
- Secondary context: Softer events such as pageviews, add-to-cart, form starts, or content engagement.
- CRM feedback: Offline conversion imports or lead-stage updates when post-submit quality matters.
Study Power: Budget, Volume, and Duration
Study Power is the likelihood that the study can produce conclusive results. It depends on the selected conversion action, daily budget, expected lift, conversion volume, duration, and holdout percentage. Low-volume conversion actions may need more time, a broader conversion definition, or a different experimental design.
Holdout and Conversion Lag
A holdout gives the study a control group, but it also means some eligible users are intentionally withheld from ads. Document that tradeoff with finance or leadership before the test starts. Then set duration long enough to capture the average conversion lag, especially for high-consideration purchases or lead-gen sales cycles.
B2B and Lead Gen Requirements
Lead-gen studies need more than a form-fill count. If Journey-Aware Bidding or offline conversion imports are part of the account, connect the lift readout to pipeline quality. The companion Journey-Aware Bidding guide explains why SQL rate, opportunity quality, and sales acceptance need to stay in the scoreboard.
Requirements Checklist
- Confirm campaign type, country, account access, and Google support path.
- Select one primary conversion action and document secondary diagnostic events.
- Review historical conversion volume, budget, and expected lift.
- Pick a holdout percentage and document the opportunity cost.
- Set duration long enough for conversion lag and post-click delay.
- Clean GA4 key events, UTMs, offline imports, CRM stages, and consent-mode assumptions.
- Preserve historical inputs with the Google Ads data retention checklist.
- Use GA4 scenario planning to compare forecasted budget moves against measured lift.

No. Availability depends on account, campaign type, region, and Google support access. Confirm eligibility with Google before building the test timeline.
What if the account does not have enough conversions?
