Five DTC shops. 10–20× the industry CTR.

The combo.

Each of the five Shopify shops below ran a variant of the same setup. The brand creates a giveaway on ZKPuzzle for Business — typically a gift card from their store. The same campaign runs an ad-slot placement alongside the giveaway to reach users who haven’t entered yet. Winners receive a real gift card; non-winners see the brand at a non-ad-fatigued moment in their morning routine.

The economic outcome: 4–7% CTR across the cohort. Industry baseline for DTC display ad placements is roughly 0.3–0.5% CTR. The 10–20× CTR uplift is the small-brand wedge.

The five shops.

Each row below is one brand running the same combo. Note that attributable sales are the dollar value of redemptions completed against gift cards and giveaways tied to the ZKPuzzle campaigns — not impressions, not clicks-that-go-nowhere.

Playfield

Why it works.

Two reasons. First — ZKPuzzle’s audience opens the app for the daily-puzzle ritual, not to consume ads. Placements show up to engaged users in a non-ad-fatigue context. Second — the giveaway mechanic gives users a reason to click through (real gift cards, real shops) rather than the pure-display-impression model of most DTC channels.

Multiply across multiple campaigns per year, add the awareness lift from views that didn’t convert immediately, and the math compounds. Goodjuju alone cleared ~$8K+ in attributable sales — proves CTR-to-conversion can compound when the audience match is right.
