If the same partners are showing up in every report, your revenue line is flat, and your agency’s updates have started to feel like a formality, you may suspect that something’s wrong and that you need a new affiliate agency. However, affiliate marketing is just opaque enough that you can’t quite prove it and you’re not sure what your next move is.
Before you start shopping for a new agency, take a step back. Replacing them will cost you time, money, and momentum, so you need to approach the problem with a cool, even head and first determine whether you’re just in a slow period.
Is It Really the Agency?
Not every underperforming affiliate program is the agency’s fault, and some of the most common causes have nothing to do with how well the program is being managed.
- The channel itself might be mature. If your affiliate program has been running for years and already works with the obvious partners in your space, double-digit growth gets harder every year. It might not be that anyone’s slacking; you may have just already captured the easy wins.
- Your margins might be the constraint. Affiliate partners go where the commissions are competitive, and if your economics can’t support big payouts, agencies will have trouble recruiting around that.
- Your product might simply have lower affiliate appeal. Some categories are a natural fit for coupons, cashback, and content partners, and others just aren’t.
- Your expectations are too high. If you’re comparing your affiliate numbers to paid social or expecting a channel to scale in a straight line, the disappointment might be in the benchmark rather than the results.
If any of these are true, you have a bigger problem to solve before you consider switching. A structural constraint will only follow you to the next agency.
The Warning Signs That You Need a New Affiliate Agency
If you’ve ruled out the structural stuff and still think something’s off, here are the signals that might point to an affiliate agency problem.
1. Partner Recruitment Has Stalled
Look at your partner list from a year ago, and compare it to today. If it’s basically the same names, that’s a problem; a healthy program is always bringing in additional partners: new content publishers, new creators, and new deal/loyalty sites. The problem is, recruitment is slow, unglamorous work, and it’s something an agency might quietly stop doing if it goes into autopilot mode. And if no one can tell you which new partners they’ve landed this quarter, they probably haven’t landed any.
2. Reporting Is Thin or Opaque
Plenty of agencies send impressive-looking monthly reports full of clicks, revenue, and a nice upward chart — all of which tells you very little actual information. If every month’s report is the same top-line totals with no breakdown by partner, you can’t see which relationships are actually working and which are dead weight. And if the numbers never tie back to your own analytics or store data, you’re taking the network’s word on program results.
3. Your Promo Calendar Is Static
Coupons and promos should follow a strategy tied to your business, margins, seasonality, and launches. If the same discount cadence has been running for a year regardless of what’s happening on your end, that’s a sign that no one is steering. Worse, an unmanaged coupon strategy can quietly erode margin by handing discounts to customers who might have paid full price.
4. Brand Protection Is Weak
A good agency actively polices your program. They watch for affiliates bidding on your trademarked terms, coupon codes leaking onto sites they shouldn’t, and unauthorized partners profiting off your brand name. It’s possible that these issues aren’t happening in the first place, but if you’ve never gotten a note from your agency about enforcing program terms, it’s worth asking why. These gaps cost you money, and they don’t fix themselves.
5. Responsiveness Has Slipped
Notice who’s driving the relationship. If you’re the one chasing updates, suggesting ideas, and following up on things that stalled, it’s likely time to move on. A good agency comes to you with recommendations before you have to ask. When replies get slow and proactive ideas dry up, it may mean your account has drifted down to the bottom of their priority list.
What to Ask Your Agency to Determine Where the Fault Lies
Obviously, you can’t just ask your agency if they’re underperforming. However, you can ask how they know whether their work is bringing in any results.
This is because a lot of affiliate revenue comes from customers who are already heading to the checkout and search for a coupon, land on a deal site, click its link, and complete a purchase that they were going to make regardless.
But an affiliate program is supposed to bring you sales you wouldn’t have gotten on your own, and a good agency can show you how they do it. They tie the network’s tracking back to your own analytics and store data, showing you which partners genuinely drive incremental sales versus which are tagging along with demand you’d already created. This incrementality points you toward which partners to invest in, which commissions to adjust, and which relationships aren’t worth what you’re paying.
So ask your agency to show you the incremental value of your program, not just total revenue. If the answer is a confident walk-through of their methodology and the data behind it, that’s a good sign. If it’s a blank look or a restatement of the same revenue number you already had, it’s a good sign that they don’t know whether your program is actually working.
This isn’t a nice-to-have or one vendor’s proprietary angle; it’s the baseline standard for knowing whether the channel earns its keep. Any agency running your program should be able to answer questions about incrementality.
Before you start interrogating your agency, start by pulling the last 6 to 12 months of your program data and looking for movement. Are there new partners in the mix consistently? Is revenue growing, flat, or propped up by one or two big partners? Is your commission spend climbing faster than the sales it’s generating?
Then, take a short list of specific questions to your agency and ask them directly:
- Which net-new partners have you recruited in the last two quarters?
- How much of our affiliate revenue is incremental, and how do you measure it?
- What have you done recently to enforce our program terms and protect the brand?
Well-run agencies will have specific partners with names and dates, a clear methodology for incrementality, and concrete examples of brand-protection actions.
What to Look For in a New Agency
Once you’ve determined that it’s time to move on, you don’t want to get stuck in another lopsided business relationship. So, what does it look like when your affiliate agency is doing the best possible work for you?
- High-performance affiliate agencies recruit continuously. There are always new partners entering the program, and they can tell you who and why.
- The agency reports on incrementality, not just top-line revenue, so you always know which partnerships are creating net-new sales.
- Your affiliate program promotional calendar is built around your business rather than a generic template, and it changes with your launches, your margins, and the season.
- Your agency actively protects your brand, watching for trademark bidding, coupon leakage, and unauthorized partners, and it tells you when it takes action.
- The agency is genuinely responsive, bringing you ideas before you ask instead of waiting to be chased.
Agencies built this way do exist. PartnerCentric is one example; instead of reporting on top-line revenue, its FUSE Incrementality tech runs the network’s tracking against a brand’s own analytics and order data to work out which partners genuinely caused sales and which are being credited for demand the brand had already created. That reconciliation flags commissions the channel didn’t earn, and those dollars get redirected toward partners the data actually supports. It also runs continuously rather than as an annual audit, so the partner mix gets adjusted as things shift. Recruitment works the same way: staffed as its own job with its own targets rather than something the account manager gets to when there’s time, and new partners are vetted against that same incrementality data before they’re onboarded.
To get a quick idea of whether an agency you’re considering will fit the bill, ask them these questions:
- How do you measure incrementality? You want a clear method for showing which partners drive net-new sales. A vague answer here tells you they’ll manage to top-line revenue and call it a day.
- How many new partners do you typically recruit in the first six months? Recruitment is the engine of a growing program, and a good agency can talk specifically about how they find and onboard new partners, not just the big names everyone already works with. Look for a real process and a realistic number, rather than a promise to “expand the program.”
- How do you handle brand protection and compliance? Ask how they monitor for coupon leakage, trademark bidding, and unauthorized partners, and how quickly they act. If you’re in a regulated space like health or finance, ask about their experience with compliance, PII, and coordinating approvals with your legal team. You want a firm that treats this as routine, not a scramble.
- What does onboarding look like, and how long until we’re fully running? A good agency has a defined transition process and can tell you what the first 90 days involve. The answer reveals how organized they are and how soon you should see momentum.
- How will we communicate, and how often? Responsiveness problems are hard to fix once they start, so set the expectation up front. Ask who your day-to-day contact is, how often you’ll hear from them, and whether they bring ideas proactively or wait to be asked.
With all that being said, talk is cheap, and many agencies are very good at telling you what you want to hear. So, if at all possible, have them show you something that already exists. Ask to see a real monthly report from a current client with the names redacted — not a sales deck, the actual report they send. Request a reference for a brand roughly your size in a comparable category, and call them directly to hear about their experience.
Frequently Asked Questions
What are the warning signs of an underperforming affiliate agency?
Recruitment has stalled, reporting is thin and top-line only, the promo calendar hasn’t changed in a year, brand protection never comes up, and you’re always the one chasing them. Apart, they deserve a closer look. Together, they describe a program on cruise control.
How do I figure out whether the fault is really with my agency?
Pull 6–12 months of program data, and look for movement in partners, revenue, and commission spend. Then, ask direct questions about recruitment, incrementality, and brand protection, and judge them on how specific the answers are.
What should I ask my current agency before deciding to leave?
Which net-new partners they’ve recruited in the last two quarters, how much revenue is incremental and how they measure it, and what they’ve done recently to protect the brand. Listen for specific names, clear methodologies, and concrete examples; if you don’t get them, it’s probably time to switch.
What should I look for in a new affiliate agency?
Continuous recruitment, incrementality reporting rather than top-line revenue, a promo calendar built around your business, active brand protection, and genuine responsiveness. Ask how each of those actually works before you sign.
The Pattern Is the Proof
One warning sign can be a fluke. But stalled recruitment, thin reporting, an autopilot calendar, weak brand protection, and a relationship you’re always chasing is not a fluke — it’s a program running on cruise control.
You now have a way to check rather than guess. Pull your data, ask direct questions, and watch how your agency answers. A good affiliate program should be growing, measurable, and actively managed. If yours isn’t and the agency can’t show you why, it’s probably time to switch to one that can and will.
