How to Choose an Affiliate Network: A 12-Point Due Diligence Checklist

Choosing the wrong affiliate network rarely fails loudly. It fails quietly: a cookie window that is shorter than you assumed, a payout threshold you never reach, commissions reversed under a clause you never read. This checklist is the process we use when we add a network to the Affpinions program finder, adapted for publishers who want to protect their time and traffic.

Why the choice of network matters more than the commission rate

A headline commission of 40% looks better than 8% until you factor in conversion rate, average order value, reversal rate and how long it takes to get paid. Publishers who chase the highest percentage often end up with the lowest effective earnings. The network sits between you and the merchant: it tracks the click, attributes the sale, validates the conversion and finally pays you. Every one of those steps is a place where money can leak.

Think of the decision as choosing a business partner rather than picking an offer. The questions below help you judge that partner on the things that actually determine what lands in your bank account.

1. Track record and reputation

Start with the basics: how long has the company traded, who runs it, and where is it registered? In the UK you can look up companies on Companies House; in the US, state business registries and the Better Business Bureau are a starting point. A network that has paid affiliates for a decade has a lot to lose by stopping. A network registered last month with no named people behind it has very little.

Search the company name alongside words like "payment", "late", "scam" and "review", and read forum threads from experienced affiliates. Be sceptical of glowing reviews on sites that link to the network with their own affiliate link, and equally sceptical of a single furious review. We wrote about this problem in detail in can you trust reviews of affiliate networks.

2. Payment reliability and payout terms

This is the single most important point on the list. Look for four things:

• Minimum payout: a $50 threshold is easy to hit for an established site; a $500 threshold can trap a new publisher's money for months.
• Payment frequency: weekly, bi-weekly, monthly or "Net-30/Net-60". Net terms mean you are paid 30 or 60 days after the end of the period in which the commission was approved.
• Payment methods: PayPal, Payoneer, wire, ACH, check, Paxum, crypto. Choose a network that pays in a way that is cheap for you to receive. Our payout methods comparison breaks down the trade-offs.
• Currency: being paid in USD when your costs are in GBP or EUR adds conversion fees every month.

You can filter by all of these in the finder, or browse lists such as networks that pay by PayPal and networks that pay via Payoneer.

3. Commission model and rate structure

Understand exactly what you are paid for. CPS (cost per sale) pays a percentage or fixed amount when a purchase completes. CPA pays for a defined action such as a sign-up or deposit. CPL pays per lead, CPI per app install and RevShare pays a share of the revenue a customer generates over time. Each model shifts risk differently between you and the advertiser. If you are unsure which fits your traffic, read affiliate commission models explained.

Check whether rates are tiered (higher rates after volume targets), whether new and returning customers pay differently, and whether some product categories are excluded or paid at a lower rate.

4. Cookie duration and attribution rules

The cookie or attribution window is how long after a click a conversion still counts as yours. Windows range from 24 hours (Amazon Associates' standard window) to 30, 60, 90 days or even lifetime. Longer windows matter most for considered purchases such as software, finance and travel, where people research before buying.

Equally important is the attribution model. Most networks use last-click attribution, so if another affiliate's link is clicked after yours, they get the sale. Some programs use first-click or split commissions between touchpoints. Ask, because it changes how valuable top-of-funnel content is to you. Programs that pay for the lifetime of a customer are covered in our guide to lifetime commission programs.

5. Tracking technology

Tracking failures are invisible to you unless you look. Ask which platform the network uses (in-house, Impact, Everflow, HasOffers/TUNE, CAKE, Affise and so on) and whether it supports server-to-server postback tracking. Postbacks are much more resilient to browser privacy restrictions than cookie-only tracking. We cover the details in affiliate tracking in 2026.

A good sign is a network that lets you add your own sub-IDs to links so you can see which page, button or campaign drove each conversion.

6. Offer and merchant quality

A network is only as good as the advertisers it carries. Look at the merchants in your niche: are they brands your audience trusts? Do their landing pages load fast and work on mobile? Would you buy from them? Promoting a weak product damages your audience's trust, and that trust is the asset that pays you over the long term.

7. Approval process

Strict approval is not a bad sign. Networks that manually review publishers usually do so to protect advertisers from fraud, which in turn protects honest affiliates from reversals. When applying, describe your site, audience size and promotional methods honestly. If you are rejected, ask why: many networks will reconsider once your site has more content or traffic.

8. Traffic-source restrictions

This is where most commission reversals come from. Before promoting, check whether the terms allow:

9. Reporting and transparency

You should be able to see clicks, conversions, pending versus approved commissions and reversals, ideally in near real time and with export options. Reversal rates are worth watching: occasional reversals for refunds or cancelled orders are normal, but a sudden spike without explanation deserves a support ticket.

10. Support and affiliate management

Good networks give you a named affiliate manager once you show traction. Test support before you commit: send a specific question about tracking or terms and see how quickly and how well they answer. If a simple pre-sales question takes a week, a payment problem will take longer.

11. Contract terms you should actually read

Skim less, read more. In particular, look for clauses on: termination (can they close your account and keep unpaid earnings?), forfeiture of balances below the threshold, changes to commission rates with or without notice, jurisdiction, and data protection responsibilities. If a clause allows the network to withhold all earnings for any reason without explanation, think carefully.

12. Fit with your audience and your plans

Finally, step back. Does the network carry enough relevant offers that you could build a whole content strategy around it? Will it still make sense if your traffic doubles, or if you move into email or video? The best network for a golf blogger is not the best network for a mobile game publisher. Browse by market or by niche to see what exists in your space.

Red flags that should stop you

• A fee to join as a publisher.
• No named company, address or registration details.
• Commission rates far above anything else in the vertical, with no explanation.
• Payment threshold or payment date that keeps "moving".
• Pressure to send traffic before you have read the terms.
• Terms that let them withhold earnings indefinitely without reason.

How to run a fair test

When you have two or three candidates, run a controlled test. Place links for comparable offers on comparable pages, tag each with a sub-ID and send traffic for a fixed period (for example four weeks or 1,000 clicks each). Then compare the numbers that matter: conversion rate, EPC (earnings per click), approval rate and the time from conversion to payment. Our revenue calculator helps you project what the results mean at scale, and the compare tool puts the terms side by side.
