Customer Retention Strategies in Paid Media
Updated: Oct 5
When it comes to loyalty, think long-term, not last-click
Key Takeaways
Fewer than 1 in 4 customers say genuine brand affection is why they stay loyal — Razorfish research calls this gap the "loyalty deficit," and it's built on function (product, checkout, price, switching cost), not points.
First-party data captured during a tentpole campaign has a short shelf life; brands that build segmented retargeting and lookalike audiences in the first 14 days after a spike outperform those who wait for the quarter-end report.
Retail media networks (Amazon, Walmart Connect, Sam's Club Connect) already have the infrastructure to treat existing customers differently from prospects — most brands are paying for that capability without activating it.
Media mix modeling is shifting from a rearview-mirror reporting tool to a forward-looking decision engine, but only 28% of marketers say their org is effective at turning MMM insights into action — and retention is the KPI most often left out of the model until it's too late.
There’s a self-serving story many marketers tell themselves: that repeat customers keep coming back out of genuine affection for the brand. But new research from Razorfish shows that fewer than 1 out of 4 customers agree. That gap is called the loyalty deficit, and it’s costing brands more than they know.
What drives customer loyalty in 2026?
The answer is less romantic and more pragmatic than brands might think:
whether the product works
whether checkout is painless
whether the price makes sense, and
whether switching to a competitor feels like effort they don't want to spend.
Discounts haven't lost their pull, but they've become the baseline, not the differentiator.
According to the Razorfish data, the benefits gaining ground now are things like:
getting first access to a drop
being treated like a VIP, or
receiving support during an actual day of need, not just a birthday email.
Loyalty, in other words, is being built more in how a brand treats people when it counts than in how many points they've stacked up.
And that value doesn't have to live inside one brand's four walls, either. More than half of consumers say the strongest perks are the ones that work across categories entirely — a coffee loyalty program that also gets you airline miles, or a coalition wallet like Fetch that pools value across retailers. That's real headroom for challenger brands that can't out-discount a category leader but can out-partner one.
One word of caution: as brands lean on AI to personalize these experiences, execution quality matters. Razorfish's research found that AI can just as easily damage the relationship as deepen it — the differentiator is whether the technology still feels like it's coming from a person who gets you, not a script or a bot.
How can I build customer loyalty into a media plan?
Audit your loyalty program against the "loyalty deficit" lens — are you offering tangible, functional value, or leaning on brand-affinity messaging consumers don't actually credit?
Gather first-party data and turn it into long-term loyalty.
Pilot one soft-perk benefit (early access, VIP service recovery, a milestone-adjacent empathy touch) alongside your existing discount structure.
Evaluate one cross-brand or coalition partnership opportunity that could extend perceived value without eroding margin.
How to preserve consumer attention post-campaign
Your tentpole media campaign brought you something valuable: real first-party data captured at a moment of high intent - who clicked, on what product or category, in which channel. It’s the accuracy of that data, not just the volume of it, that makes first-party data so useful for precise retargeting and lookalike modeling as third-party cookies degrade.
We know loyalty initiatives need to go beyond points and create memorable experiences consumers really care about. But that starts with what you do in the two weeks right after the spike.
Day 0-1: Build the custom audience before the spike cools. Push spike-engaged users (site visitors, retail media ad clickers, DSP-served impressions) into a dedicated retargeting segment in your DSP, split by product or category clicked - not one blended pool. A blended audience gets generic creative; a segmented one gets creative aligned with what they actually looked at.
Day 2-5: Retarget on the channel where intent was highest, then layer DSP and paid social around it. Sponsored search on Amazon or Walmart converts the highest-intent segment fastest; DSP Display and Paid Social extend reach to the browsers who didn't purchase yet.
Day 5–7: Build the lookalike in parallel, not after. Use the same spike segment to seed a prospecting lookalike audience. The point about first-party data accuracy applies directly here: a lookalike built off real, spike-captured behavior outperforms one built off broader historical data.
Day 7–14: Shift paid budget from spike-segment retargeting to loyalty-program promotion. This matters because willingness to trade data for value is real and growing. Deloitte's research found that 89% of Gen Z and 87% of millennials surveyed are willing to share personal information in return for more personalized offers or experiences.
This is the window to promote loyalty or rewards incentives tailored to each segment and the category they engaged with, not a generic program ad to everyone.
Retail media: The overlooked loyalty channel
Retail media networks (RMNs) have loyalty infrastructure already built in: Amazon's Brand Tailored Promotions, Walmart Connect's shopper segments, paid social suppression and sequencing, and programmatic retargeting all let you treat existing customers differently from prospects, inside the same media buy you're already running.
And Walmart’s recent restructuring, which aligns Walmart Connect with Sam’s Club Connect for shared capabilities, champions the membership model as a persistent, relationship-based view of customers rather than a series of one-off transactions.
It means retailers can now see not only what a customer bought, but what ads they were exposed to, how they engaged, what they did next, and how their patterns emerge over time. These first-party data points form the foundation for repeat purchases and lifetime value, not just campaign-level ROAS.
That’s golden for brands, as RMNs are quietly becoming loyalty engines informing long-term brand equity, not just immediate performance. If your team is still treating every impression as a single-touch acquisition moment, you’re paying for infrastructure you’re not using.
How can I build customer loyalty using retail media networks?
Start with a customer analysis that compares the cost and value of acquiring a new-to-brand customer against the cost and value of retaining a brand loyalist. From there, identify which paid media channels in your current mix are being used exclusively for acquisition, and map out retention audiences that could be activated instead. Apply a framework for sequencing paid media touchpoints to existing customers based on purchase history and lifetime value tier, rather than treating all retargeting as one undifferentiated pool, and evaluate ]the RMN's closed-loop measurement capabilities to ensure no retention-focused spend is left on the table.
Media mix modeling (MMM) as loyalty engine
Most teams treat media mix modeling (MMM) as a rearview mirror: run the campaign, wait for the quarter to close, then let the model tell you what worked. But EMARKETER's Media Mix Modeling Trends 2026 report (to which Exverus's own VP of Analytics Joshua Edelman contributed) confirms that gap is now the industry's biggest measurement constraint.
MMM is evolving from a reporting tool into a decision engine, but most marketers aren't ready for that shift. Only 28% of marketers say their organization is very effective at converting MMM insights into action! That's likely because they’re thinking of MMM after a campaign, rather than before. EMARKETER's report shows marketers running MMM reports sporadically instead of timing them strategically.
The mismatch shows up hardest in customer retention strategies. Acquisition spend gets modeled aggressively because the feedback loop is fast. Retention rarely gets the same treatment — the payback is slower, the attribution murkier — so it gets planned by instinct, or worse, left out of the model entirely until someone asks why churn spiked after a tentpole event. That's backwards. As EMARKETER reports, the optimal modeling cadence depends on the decision being made, which means if retention is a KPI you’re seeking in Q4, it needs to be in the model before Q4, not reconstructed from Q3's numbers after the fact.
Before you build your holiday retention budget, model it. Before you brief your loyalty program refresh, size it against your other channels in the same tool you'd use to defend a paid social increase. MMM done right doesn't just tell you retention worked — it tells you how much to put behind it before you needed it to.
How do I model customer retention strategies in MMM?
Add retention/loyalty as a standing line item in your MMM inputs now, ahead of Q4 planning — not as a post-hoc addition. Set your modeling cadence to match your decision calendar: quarterly retention decisions need quarterly-relevant model inputs, not just annual reporting. And require a documented expected payback for loyalty spend the same way you would for any acquisition channel — no more "soft" budget lines.
