How to Vet Affiliate Applications in Five Minutes or Less
A repeatable review routine for affiliate applications: the three checks that predict good partners, the red flags that predict fraud, and form questions that do the vetting for you.
Every application in your queue is one of three people: a genuine partner, a harmless tire-kicker who will never place a link, or someone planning to route self-purchases and coupon abuse through your program. The job of vetting is to admit the first, tolerate the second, and stop the third — in about five minutes per application, because a queue that takes longer stops getting reviewed at all.
The three checks that predict a good partner
Check the channel exists and is theirs. Open the website or profile they listed. You're confirming three things in thirty seconds: it's real, it's active (posted in the last couple of months), and it plausibly belongs to the applicant (the site's about page or handle matches the application name or email). No channel listed at all isn't automatically a rejection — some legitimate partners promote through newsletters or private communities — but it moves the application to "ask a follow-up question" rather than instant approval.
Check the audience fit. A crafts blog applying to a coffee program isn't fraud, but it isn't going to convert either, and misfit partners generate the support load ("why aren't my clicks converting?") without the revenue. You're not judging quality — a small, scrappy site in exactly your niche beats a big generic one every time. Relevance over reach.
Check the promotion plan reads like a human wrote it for you. One sentence of "I'll write a comparison against the two tools I currently recommend" is worth more than three paragraphs of pasted boilerplate. Applications blasted at fifty programs read generic because they are. You're looking for any detail that proves they know what your product is.
The red flags worth an instant rejection
Free email domain plus no channel plus a promotion plan that mentions "cashback" or "coupon aggregation" you don't allow — that combination is the classic self-purchase setup. Same for a channel whose audience is in a country you don't ship to, an application arriving minutes after a big discount code went live, or a portfolio of parked domains. And any applicant whose plan is bidding on your brand name in search ads gets a rejection with your PPC policy attached — that traffic was already yours.
One flag alone is rarely conclusive. Two together usually are.
Make the form do the vetting for you
The fastest review is the one your application form already did. Three fields carry most of the signal: "Where will you promote us?" (URL or handle, required), "How does your audience find you?" (one line — reveals SEO sites, newsletters, communities, and the people who can't answer), and "What would you create first?" (the boilerplate detector). Add a checkbox acknowledging your program terms — it costs honest applicants nothing and gives you a clean contractual anchor when you later remove someone for breaking the rules they ticked.
Skip asking for traffic numbers. Applicants inflate them, you can't verify them, and small-but-relevant beats big-but-generic anyway.
Auto-approve or manual review?
Manual review is the right default for stores. The queue is small at WordPress scale, and one bad partner costs more cleanup than a hundred approvals cost time. Auto-approval fits when commissions only accrue on real purchases and you hold referrals for review before payout anyway — then a bad actor who slips in earns nothing until a human looks at their referrals. If you auto-approve, tighten the other end: longer holding periods and fraud checks on the referral, not the applicant.
Whichever you choose, answer fast. Approval within a day, while your product is still on their mind, is the difference between a partner who places a link this week and one who forgot you existed. A rejection deserves speed too — one kind sentence, no debate. "Thanks for applying — we're focusing on partners with an active audience in [niche], so we won't be a fit right now" closes the loop without opening a negotiation.
Keep a paper trail
Whatever tool you run the program on, make sure each decision leaves a note: who approved, when, and anything odd you noticed. Six months later, when a partner's referral pattern turns strange, the application note ("no site listed — approved on the strength of newsletter") is the context that makes the fraud review fast. Vetting isn't a gate you pass through once; it's the first entry in the partner's file.
