How Consumer Purchase Lift Works
Match Exposures to Purchases
The media exposure file (including a control group) is matched to Affinity’s purchase data to create a combined dataset.
Calculate Spend & Conversion Lift
Lift in spend and conversion is calculated for the exposed group and compared against the unexposed control group.
Compute iROAS
Adding campaign cost data enables calculation of incremental Return on Ad Spend — the truest measure of campaign ROI.
The Proof is in the Purchase
Unlike other methods, we use actual credit and debit card data to precisely measure your marketing effectiveness.

Testimonials
Brian Kaminsky, Chief Data Officer
“By partnering with Affinity to measure the impact of Mattress Firm’s digital audio advertising, particularly on their bottom line, we were able to demonstrate the power of the brand’s partnership with iHeart to drive sales and strong ROI. We also gained insights to optimize campaign performance that we are already applying.”
How We’ve Made an Impact
