Conversion lift is a metric used to measure the incremental impact of an advertising campaign on conversions, which are actions that align with business goals, such as purchases, sign-ups, or other predefined actions. This metric helps advertisers determine the effectiveness of their campaigns in driving actual business outcomes beyond baseline performance.

How Conversion Lift is Measured

  1. Baseline Measurement: Before the campaign starts, the typical conversion rate is established.
  2. Campaign Execution: The ad campaign is run, with a specific audience being exposed to the ads.
  3. Control Group: A portion of the target audience is not exposed to the ads, serving as a control group to measure baseline conversions.
  4. Measurement Period: Conversions are tracked over the duration of the campaign for both the exposed group and the control group.
  5. Comparison: The conversion rates of the exposed group and the control group are compared to determine the incremental conversions attributed to the ad campaign.

Example Calculation

If the control group has a conversion rate of 5% and the exposed group has a conversion rate of 8%, the conversion lift is calculated as follows:

Conversion Lift=Conversion Rate (Exposed Group)−Conversion Rate (Control Group)Conversion Rate (Control Group)×100\text{Conversion Lift} = \frac{\text{Conversion Rate (Exposed Group)} – \text{Conversion Rate (Control Group)}}{\text{Conversion Rate (Control Group)}} \times 100Conversion Lift=Conversion Rate (Control Group)Conversion Rate (Exposed Group)−Conversion Rate (Control Group)​×100

Conversion Lift=8%−5%5%×100=60%\text{Conversion Lift} = \frac{8\% – 5\%}{5\%} \times 100 = 60\%Conversion Lift=5%8%−5%​×100=60%

This means the ad campaign resulted in a 60% increase in conversions compared to the baseline.

Benefits of Using Conversion Lift Studies

  1. Objective Analysis: Provides an objective way to measure the impact of advertising, free from biases that might affect subjective evaluations.
  2. Improved Strategy: Helps in refining targeting, creative strategies, and overall campaign approaches based on what drives conversions.
  3. Enhanced Budget Allocation: Informs better allocation of marketing budgets towards tactics and channels that demonstrate higher conversion lifts.
