Question: Incrementality testing uses a control vs. treatment methodology. In which of the following experiments is the control group completely untouched by the experiment?

• Conversion Lift Testing
• Brand Lift Testing
• A/B Testing

Explanation

LinkedIn Conversion Lift Testing measures incrementality by separating eligible members into a treatment group and a completely untouched control group. The treatment group can be exposed to ads, while the control group is withheld from the campaign. This design helps identify conversions that happened because of LinkedIn ad exposure. It is used to measure outcomes that would not have occurred without the campaign.

Why the other options are incorrect

Brand Lift Testing also uses control versus treatment methodology, but the control group may still receive survey exposure for perception measurement.

A/B Testing compares campaign variations, but it does not keep one group completely untouched by the experiment.
