Programmatic Advertising Attribution: Making Sense of DSP Data

Why Programmatic Attribution Is So Difficult

Programmatic advertising — buying display, video, and native inventory through demand-side platforms (DSPs) like The Trade Desk, DV360, or Amazon DSP — has a fundamental attribution problem. Most programmatic conversions are view-through: the user saw your ad, didn't click, and later converted through another channel. DSPs claim all of these as their conversions.

The result: programmatic ROAS looks great in DSP dashboards and terrible in click-based attribution tools. The truth is somewhere in between — and finding it requires a systematic approach.

The Programmatic Attribution Framework

Step 1: Use ClickMagick to track all clickable programmatic ads (display ads with click-through URLs). This gives you a baseline of click-based conversions. Step 2: Compare ClickMagick's click-based conversions against your DSP's reported conversions. The gap is your view-through attribution. Step 3: Run an incrementality test — pause programmatic for 2 weeks and measure whether overall conversions decline. If they don't, programmatic may not be driving incremental revenue.

When Programmatic Actually Works

Programmatic delivers genuine incremental value for: brand awareness campaigns where you're reaching new audiences, retargeting campaigns where you're re-engaging known visitors, and sequential messaging campaigns that move prospects through a funnel. It tends to over-claim credit for: conversions that would have happened anyway through other channels.
