Brand Search Lift
The incremental increase in branded search volume attributable to a marketing campaign, measured by comparing exposed vs. unexposed (or pre/post) periods.
“Is our brand campaign making people actively seek us out?”
Whether upper-funnel media is building enough salience to change search behavior — a strong proxy for brand awareness impact.
Whether the additional search interest converts into sales, trials, or prescriptions — that requires a downstream conversion metric.
Numerator
Incremental branded search volume during/after exposure
Denominator
Baseline (control or pre-period) branded search volume
Example
Branded search volume in the exposed geo rises from 10,000/week to 13,500/week while the control geo stays flat at 10,000/week. Brand Search Lift = (13,500 − 10,000) / 10,000 = 35%.
Recommended visualization: Line chart comparing exposed vs. control search volume over time
Best measured with a geo-holdout or matched-market design. Without a true control group, use seasonally-adjusted pre/post comparison and flag as directional, not causal.
- Verify control and exposed markets are demographically matched
- Adjust for seasonality and concurrent campaigns/promotions
- Exclude branded search cannibalized by paid search campaigns bidding on the brand term
- Attributing all search lift to the campaign when a competitor event or news cycle also occurred
- Using national search trends with no control group and calling it 'lift'
