This Week’s Stat: The Spaced Repetition Effect: Optimizing Frequency with Autonomous Media

In this week’s feature, StreetMetrics pulls from a recent study conducted in partnership with Coco Robotics to explore how moving sidewalk media builds unique reach and frequency in urban environments. By analyzing fleet data across Los Angeles, Chicago, and Miami, the study uncovered a consistent rhythm in how audiences interact with the network. For people who encounter the fleet multiple times in a month, the average interval between unique robot exposures stays remarkably steady: between 1.0 and 1.6 days.

The Insight

This pattern closely resembles the concept of “spaced repetition” found in learning science. While high-impact stationary formats provide the powerful, constant presence that anchors a market, autonomous sidewalk units offer a complementary cadence. These exposures arrive frequently enough to reinforce brand memory, but with enough of a gap, roughly 24 to 36 hours, to keep the messaging feeling fresh and dynamic as it follows the flow of a pedestrian’s daily routine.

For advertisers, this creates a real-world “playlist” effect. Because a viewer is likely to see several different unique robots over the span of a month, there is a natural opportunity to run multiple creative executions in parallel or lean into sequential storytelling, ensuring the brand story evolves alongside the consumer.

StreetMetrics: Turning OOH Data Into Decisions

StreetMetrics was founded to solve the unique technical challenges of measuring autonomous and highly mobile vehicle fleets. By tackling the complexities of measuring vehicles that move through dense urban environments, StreetMetrics empowers operators and brands to turn dynamic exposure data into actionable intelligence.
