Seven checks for affiliate marketing providers

The costliest mistake is appointing an affiliate marketing provider whose polished demonstration masks a poor fit with the programme's real work. If it cannot support sales capture, creative approval or reporting as needed, a convincing presentation will not repair that mismatch. Start from the operating needs, then test every offer against them.

Mistake: Buying the presentation instead of the service

What goes wrong: a demonstration steers the brief towards features that look impressive. Why: when suppliers respond to different expectations, their claims about tracked sales, creative approval and reporting cannot be compared fairly. The team may discover too late that an important part of its affiliate work is unsupported.

Fix: decide the required outcomes and their relative importance before meeting suppliers. Give each provider the same questions, and treat a demonstration as evidence for its response, not as the source of your requirements. Use the selection checklist to keep expectations consistent across offers.

A short response card helps keep the evaluation centred on the same details. Ask every provider to fill in these points in order, then mark any unanswered requirement before comparing scope or fit:

Mistake: Accepting tracking as a blanket guarantee

What goes wrong: treating a general tracking assurance as proof of complete measurement. Why: the recorded action, attribution window and any stated limits affect what the provider can report, so an unqualified promise cannot tell you whether measurement fits the programme.

Fix: request the capture methods, attribution window, known limitations and details of any sub-network route. Compare those particulars with your needs using the attribution methods as a reference. Make any gaps explicit instead of treating a broad tracking claim as settled evidence.

Mistake: Failing to identify the publisher route

What goes wrong: assuming access always comes directly from the provider. Why: publisher access may pass through a sub-network, leaving the team unclear about which route a broad service promise describes. Without that distinction, an offer is harder to compare with the programme's own requirements.

Fix: have the provider identify whether publisher access is direct or routed through a sub-network. Record that answer alongside the tracking explanation, but keep the two separate: access describes the publisher route, while capture methods describe how sales are measured. That distinction makes the service being compared clearer.

Mistake: Treating a dashboard as proof of data responsibility

What goes wrong: reading a dashboard as if it also settles who handles information. Why: reporting screens do not establish the provider's role, whether a data processing agreement applies, or what happens to information after the service ends. Keep those points in your data protection review, separately from dashboard capability.

Fix: ask the provider to describe its role and end-of-service handling, then record whether an agreement applies. The Information Commissioner's Office explains its UK data protection role. Use data protection guidance to frame accountability questions, then compare the response with your requirements; a dashboard cannot settle responsibility.

Mistake: Leaving paid-link labelling between parties

What goes wrong: assuming the provider will take care of paid-link labels without agreement. Why: if no one asks how disclosure will be applied or recorded, the brand may be unsure what support it is receiving or which tasks the service includes.

Fix: set out the supplier's contribution and the brand's responsibilities, then compare the proposed workflow with the advertising rules and the CAP Code. Ask how paid adverts will be recognisable and how labelling will be recorded. Software features alone do not establish who has agreed to do each part.

Mistake: Verifying only the name used in a pitch

What goes wrong: checking a trading name but not the business named in the agreement.

Why: the name used in a pitch can differ from the legal entity, so the team might verify one identity while contracting with another. That leaves the comparison detached from the party actually accepting the terms.

Fix: for a limited company provider, match the legal entity and registered address with official company information, then check filing history before accepting the proposal. Read the Companies House annual accounts guidance as part of that check, and confirm the contracting party is the business whose details were examined.

Mistake: Comparing the fee but postponing exit conditions

What goes wrong: weighing a headline charge while putting scope, notice and departure questions aside. Why: minimum fees or exclusivity can affect how a price should be judged, and leaving data export until renewal may expose a format gap after the working relationship is already under way.

Fix: consider the fees alongside agreed scope, minimum charges, notice periods and exclusivity in the commercial terms. Add exit conditions to the quality checklist: confirm whether historical data can be exported and in which format before deciding, rather than waiting for renewal discussions.
