Cal Donnelly, SVP of Strategic Key Accounts at Rokt, joined Marcus Johnson and Principal Analyst Sky Canaves on eMarketer's Behind the Numbers podcast to talk about how consumer intent shifts across the year, what's really happening in the seconds after a customer completes a purchase, and what it means to buy a moment instead of buying media.

A few things from the conversation worth unpacking.

Q4 isn't the only peak

Retail planning still defaults to Q4, but Cal's argument is that the other moments might actually be bigger. Take Summer for example, it is just as big an intent window for a large slice of the consumer economy, and in some years bigger. Live events have been breaking records since the pandemic on pent-up demand alone, and this year the movie industry is on track for its best ticket sales since 2019, with people increasingly treating a trip to the theater as a whole outing rather than a quick errand.

Sky picked up the thread from the calendar side: promotional windows keep sliding earlier, Prime Day included, and for the second year in a row holiday growth is forecast to come in under the yearly average. Same intent, different months.

The biggest moments aren't always the planned ones

That calendar shift is one thing. What surprised both Cal and Sky more was how often the real spike came from somewhere a planning deck never accounted for. Cal's example was Fanatics setting an all-time order record off the back of the Knicks' title run. Nobody could have forecast that at the start of the year, even knowing the NBA finals were on the calendar. Sky landed on the same moment from a different angle: marketers could plan for the date the championship would happen, not for what actually happened in it.

Which is why both kept coming back to flexibility as the real skill here, not forecasting.

Checkout doesn't end the moment, it opens a new one

Flexibility around big cultural swings is one kind of opportunity. The other, smaller and far more frequent, is what happens in the seconds right after someone checks out. Cal named three things going on there: the data customers hand over is accurate, because they need that order delivered correctly; their attention is unusually undivided, since they're not mid-scroll the way they are everywhere else online; and they're still riding the small high of having just bought something they wanted.That combination, real data, high engagement, and a buying mindset, is what makes the post-checkout window a meaningful place to surface an additional offer or piece of content that a customer might actually want.

Sky called it post-purchase momentum. The order going through doesn't close the door, it just changes what's on the other side of it, something closer and more relevant than the retargeting that shows up days later.

The goal isn't more decisions, it's the right one

Cal was direct about the risk of getting this wrong. Customers have already made a string of decisions by the time they reach checkout, and piling on more choice creates what he called the paradox of choice. The better move is showing up with one thing that actually fits, whether that's a gift card or a loyalty incentive, rather than a stack of offers competing for the same five seconds of attention. Products like Rokt's Shopper Rewards are built around exactly this, giving customers a reason to come back to a publisher's site rather than just closing the tab.

Sky and Cal closed on the same note from different angles. For platforms, that means treating the post-checkout window as part of the customer relationship, not a separate ad slot. For brands, it means staying loose enough to act when a moment turns out bigger than the calendar said it would be.
