If you’re a financial services brand with a presence on NerdWallet or Bankrate, you’re already doing something right. Comparison sites are a powerful part of the acquisition mix, and being ranked well on the biggest ones absolutely matters. But if you’ve ever found yourself wondering whether your affiliate channel is pulling its full weight, or whether you’re measuring it in the right way, this is worth a read.
Here’s how we think about building partnerships that actually perform.
Think about your publisher mix the way you’d think about any portfolio
Most brands naturally anchor to the largest comparison sites, and that makes sense. The traffic is significant and the credibility is real. But there’s a real benefit to extending beyond them, and it goes beyond just reaching more people. When a prospective customer is researching a savings account or a credit card and they keep seeing your brand ranked well across different sites and in different contexts, that repetition does something. It validates the decision they’re already leaning toward and builds familiarity before they’ve even landed on your site. This is what’s sometimes called the halo effect, and it’s worth designing for deliberately.
Mid-sized comparison sites and contextually relevant native placements (think editorial content that sits alongside the product someone is already researching) can play a real role in that process. The question isn’t whether the biggest sites are worth your investment. They are. It’s whether you’re leaving something on the table by not extending further.
Give your publishers something to work with
Here’s something worth thinking through if you haven’t already: what data are your publishing partners actually working from when they’re trying to optimize for you?
In most affiliate programmes, publishers can see clicks and account opens. That’s what they’re optimizing toward, because that’s what they have visibility into. But if what you actually care about is funded accounts, long-term deposit values, or customers who are going to stay, that signal lives further downstream than your publishers can see, unless you share it with them.
When you close that feedback loop, by sharing down-funnel conversion data with key partners, the relationship changes. Your publisher isn’t just trying to drive volume anymore. They’re trying to drive your version of a good customer, because you’ve told them what that looks like. That’s a more productive partnership for both sides, and in a channel built on performance, it tends to produce better results.
The good news is that this doesn’t require passing individual customer records to your publishing partners. Most brands do this through their affiliate network platform, sharing aggregated outcome signals like funded account rate by publisher or average deposit value by traffic segment. That’s enough to meaningfully shift how a publisher optimizes, and it sits comfortably within standard data privacy frameworks. The specifics will vary depending on your market and product type, so it’s worth a conversation with your compliance team before you set it up, but it’s rarely the blocker people assume it will be.
Check what your measurement is actually telling you
Last-click attribution is the default for most affiliate programmes, and for a lot of channels it’s a reasonable starting point. In digital partnerships, though, it can give you an incomplete picture.
The reason is fairly simple. Financial services customers don’t always convert in a linear way. Someone might research on a comparison site, go away, see your brand elsewhere, and then come back directly to your site to apply a week later. In a last-click model, that journey credits the direct visit and gives nothing to the comparison site that did the early work. Over time, if you’re making investment decisions based on that view alone, you may be undervaluing the channel.
Incrementality testing is worth building into how you think about publisher performance. The core question it helps you answer is: which customers did this partner actually bring us, versus customers who would have found us anyway? It takes more effort to set up than standard attribution reporting, but it gives you a much more honest view of where the channel is genuinely moving the needle.
Match your spend to what the business actually needs
One pattern worth examining is whether your affiliate investment is responsive to your business needs in real time, or whether it’s running on a relatively static plan. For financial services brands, the value of a new customer isn’t constant. Deposit quality, balance size, and tenure all affect how valuable an acquisition actually is, and those priorities can shift depending on where the business is at.
A more dynamic approach treats publisher investment as something that responds to those signals. When you need high-balance, long-term depositors, your bidding strategy and the placements you’re prioritising should reflect that. When volume matters more, you dial accordingly. It’s not a radical departure from how most teams already think about paid channels. It’s more about applying that same logic to partnerships, where it’s sometimes treated as more of a set-and-check activity.
Bottom line
Digital partnerships and affiliate channels can be a significant source of growth for financial services brands, and the good news is that the levers for improving performance are fairly practical. Broaden your publisher mix beyond the obvious names. Share more meaningful data with your partners so they can optimize for outcomes that matter to your business. Check whether your measurement is giving you the full picture. And make sure your investment strategy is responsive to what the business actually needs at any given point.
If you’re already doing all of this, great. If any of it prompts a question about how your current programme is set up, that’s probably a useful starting point for a conversation.
