The starting point: great product, invisible ads
A D2C home goods brand had strong organic word-of-mouth and solid repeat purchase rates. Their challenge was new customer acquisition. They were running standard display campaigns on Google Display Network — static banners in 300x250 and 728x90 formats with clean product photography and a discount offer. CTR was sitting at 0.06%. Not unusual for display, but the conversion rate on those clicks was also poor: 1.1%. Their landing page analytics showed average session duration of 38 seconds. Visitors were arriving, glancing, and leaving.
The problem wasn't the product. The problem was the ad experience. Static banners create passive impressions. The visitor's eye skips them the same way it skips sidebar content it has learned to ignore. We needed to create a moment of active engagement before the click — something that would shift the visitor from passive scrolling to deliberate interest.
The test: a swipe-comparison format
The brand's strongest product differentiator was material quality — their products felt noticeably different from mass-market alternatives. This was impossible to communicate with a static image. We designed an interactive display unit built around a swipe-to-compare mechanism: a simple left/right drag that revealed a side-by-side comparison of their product against a generic alternative, with tactile texture labels and a quality callout that appeared on interaction.
We built two versions. The first was the standard static banner with the same product image and discount offer. The second was the interactive unit. Both ran to the same audience segment — retargeting pool of site visitors who had viewed product pages but not purchased — with equal budget splits for three weeks.
The interactive unit loaded in under 1.2 seconds on mobile (we optimized aggressively for this — a 4-second load time would have killed the test). The interaction required one gesture: a single swipe. No instructions. The reward for swiping — the comparison reveal — was immediately visible and satisfying. Users who completed the interaction were routed to a product page that continued the quality narrative rather than a generic homepage.
The numbers after three weeks
The interactive unit's interaction rate was 8.4% — meaning 1 in 12 people who saw it engaged deliberately. Of those who interacted, 31% clicked through to the site. Post-click session duration averaged 2 minutes 47 seconds, compared to 38 seconds from the static banner. The conversion rate on interactive-sourced visitors was 4.3% versus 1.1% from static.
Overall, the interactive unit produced 4.1x more revenue per thousand impressions than the static banner at the same CPM. We scaled it to 70% of the display budget. The static unit was kept as a control at 30% for ongoing comparison. Over the following 60 days, the quality gap held. Interactive display had earned its place as the primary format for this audience segment.
What this generalizes to
Interactive display isn't a gimmick. It earns its keep when the interaction is genuinely connected to what makes your product worth considering. The swipe-compare worked for this brand because comparison was the natural way their best customers described the difference. For a SaaS product, a simple calculator that produces a relevant estimate might do the same job. For a service brand, a before/after story carousel might work better. The format is secondary. The principle is constant: active attention produces better downstream behavior than passive impressions, and that difference shows up clearly in conversion data.
Results from a real engagement. Creative performance varies by audience, placement, format, and execution quality.
