Getting an Audience Into Your Live Stream Isn’t the Same as Keeping Them: How to Get the Most Out of Cross-Session Retargeting
Once your ads have brought viewers in, what should you actually do with them next?
Live commerce is one of the few segments in Taiwan’s market still holding real growth momentum, and more and more brands are using ads outside the live-streaming platform to bring in audiences who were never part of that platform’s ecosystem to begin with. But once those ads have brought viewers in, that audience often goes unused after a single stream ends, and the next stream simply reaches out to a fresh batch of strangers all over again.
1. Reaching viewers doesn’t mean you can bring them back for the next stream
If you sort the viewers in a live stream by whether the brand can proactively reach them again before the next stream, they fall roughly into two groups. One group already follows the brand’s account. The other hasn’t followed yet and is watching for the very first time. This second group can come from all sorts of places: an off-platform ad, an algorithmic recommendation (a home-feed suggestion, say), or a link a friend shared. How a brand goes about winning these two groups back before the next stream looks very different.
For viewers who already follow you, the platform comes with a whole set of built-in ways to bring them back. YouTube subscribers who’ve hit the bell get a notification before you go live; Instagram followers see a prompt pop up the moment the brand starts streaming; friends of a LINE Official Account can be sent a message about the next broadcast directly. But all of these share one prerequisite: the viewer has to have already followed, subscribed, or added you as a friend, effectively raising their hand to say “I want to be notified.”
The viewers who haven’t followed are a different story. They’re watching for the first time, and they might even call out “+1” and place an order on the spot, but once the stream ends, unless they’ve actively followed or subscribed, they aren’t on any platform’s notification list. When the next stream goes live, YouTube has no one to notify, Instagram won’t push them a go-live prompt, and LINE certainly can’t message someone who isn’t a friend.
It’s true that Instagram’s and YouTube’s algorithms will recommend an account to people who “might be interested but don’t follow it.” But that’s a prediction the platform makes based on its own interest model, not a notification the brand can trigger. Whether it gets shown, and to whom, isn’t something the brand controls. In other words, the only proactive re-engagement the platform’s native tools can deliver is limited to people who already follow you. For viewers who haven’t followed but have come into a stream before, the brand has no tool to reach them on its own.
2. What DSP fills in is exactly the group the platform can’t bring back
Before we even get to bringing people back, that first step of getting them into the stream can be done more precisely too. With audience analysis, you can identify the people most likely to be interested in a brand before you run a single ad, and place those ads on the sites and apps they already spend time on, so the audience you bring in is a closer fit for the brand’s target customers from the start, rather than broad, untargeted exposure.
From there, as your DSP programmatic ads bring viewers into the stream, you can also package the people who “saw this ad campaign and actually entered the stream” into an audience list. Before the next stream goes live, or even during a stream itself, you can run ads to that list again to let them know a new broadcast is coming. This is precisely how DSP reaches the group that the platform’s native re-engagement tools leave behind, even though they’ve left a clear record of their interest.

For a brand, this means no live stream has to start from zero. The audience your DSP ads brought in during the first stream, simply by having entered it once, becomes a group you can prioritize for the second stream. And compared with total strangers who’ve never encountered the brand, these viewers have already had one point of contact, so the cost and difficulty of bringing them back are usually lower than finding people from scratch.
3. People who came into the stream are worth prioritizing over those who only saw the ad
Not everyone a DSP ad reaches actually steps into the stream. Some scroll right past the ad; others genuinely click through to watch. These two groups differ in how interested they are in the brand, and the effort you put into retargeting them next time shouldn’t be the same either.
Over the course of a campaign, DSP can already distinguish between people who “only saw the ad” and people who “saw the ad and clicked through.” Those who actually clicked in to watch have expressed a clearer interest in the brand, so putting your budget on this group first before the next stream tends to bring them back more efficiently than reaching a fresh batch of strangers. Separating out the audience that has come into a stream before and retargeting them first is how you make sure every re-engagement is money well spent.
4. Every live stream builds on the last
The benchmark for the next phase of live commerce shouldn’t just be how many viewers a single stream reached, but whether that reach was retained and turned into an asset the next stream can draw on directly. By using DSP to build up a list of viewers who came into a stream, and prioritizing that audience for retargeting before the next broadcast goes live, you fill in the group the platform’s native re-engagement tools can’t reach, and each stream’s results stop being a one-off and start compounding over time.
FAQ
Q1：If a viewer came into a stream but didn’t order at the time, is there still a chance to reach them again?
Yes, and the key is doing it the right way. If these viewers don’t follow the brand, the platform’s native notifications can’t find them, but as long as they entered through a DSP ad, they can be packaged into a list and served ads again before the next stream goes live, letting them know the brand is about to broadcast.
Q2：Does this still work for brands that don’t stream very often?
A2：Yes, and the effect may be even more pronounced. The fewer streams you run, the more valuable each stream’s incoming audience becomes. If the people who came in aren’t recorded, the next stream has to start reaching strangers from zero all over again, which actually costs more. Brands that stream infrequently have all the more reason to hold on to every viewer who came in and build them into a list the next stream can use directly.
