A Q3 data-first case study showing live, community-driven streamer raids delivered dramatically higher purchase intent and much lower cost per purchase than programmatic banners during our autumn campaign. If you manage a consumer brand budget, these numbers show where to reallocate for real ROI.
You probably have two slides in your quarterly deck: programmatic CPMs rising, and conversions flat. Those slides are why you are reading this. We ran a controlled test across September, isolating live streamer raids against matched programmatic banner buys, and the numbers are not close.
We matched budgets, audiences, and timing to remove excuses. Two $100,000 buys, same geo, same creative assets adapted for format, same one-week flight windows during peak autumn streaming hours, 6:00 p.m. to 11:00 p.m. ET. Tracking used UTM tags, unique promo codes in chat overlays, and a brand lift survey panel fielded pre and post exposure to measure purchase intent.
We measured direct conversions, tracked promo redemptions, and ran brand lift surveys to capture purchase intent changes.
Raw outcomes tell the story.

These are not small multiples. Live raids delivered 64x more purchases for the same budget, and a roughly 6x greater lift in purchase intent.
Three mechanisms explain the math.
Attention, not impressions. People who watch a streamer are present for minutes, not milliseconds, and they are actively engaged. That attention converts. In our tests, a single 20+ minute exposure produced a purchase intent lift similar to 6 to 8 banner impressions.
Social proof in real time. Chat activity and in-stream endorsements made the brand feel recommended by peers. The immediate question-and-answer in chat removed friction, accelerating clicks and conversions.
Frequency with trust. The average viewer saw our brand 4.2 times across raids. Each additional exposure added about 1.6 percentage points of purchase intent up to the third exposure, creating a compounding effect you cannot buy in a single programmatic flight.
If programmatic is delivering CPM-driven scale but no downstream revenue, raids offer a measurable, demand-driving complement. Here is the simple math for a marketing director: reallocating even 20 percent of a programmatic budget into coordinated live raids in our test increased incremental purchases by roughly 3,200 for the same spend, with stronger brand lift and far lower cost per acquisition.
We do not claim raids replace all programmatic activity. Banners still play roles in upper funnel reach and retargeting. However, when your KPI is purchase intent and measurable conversion, community-driven live activations create outsized, compounding ROI that programmatic display cannot replicate.
We controlled creatives, timing, and audience targeting. We used unique promo codes and UTMs to avoid double counting. Brand lift was fielded with a 1,200-person panel matched to our demo. We adjusted for viewability, bot traffic, and non-human impressions in the programmatic buys. The delta remained robust across sensitivity checks.
Numbers like these change how you think about budget allocation.

I am happy to map what these results mean for your next quarter, without any marketing fluff.
