Why an affiliate marketing review methodology must separate claims from proof
A commercial review method for affiliate marketing: what gets assessed, what does not, and how editorial judgement is kept apart from vendor claims.
What to take away
- The IAB 2026 Outlook Study: September Update is dated September 2026, and it revises the trade body's view of digital advertising for the year. A review should cite dated sources like this rather than a vendor summary.
- Say what was assessed: contracts, published pricing, integration documentation, rulings and company filings. Then say plainly what was not.
- Hold vendor claims, independent evidence and editorial judgement in separate fields so readers can see which is which.
- Illustrative example: a team comparing three platforms at £500 a month is weighing £18,000 a year in licence fees alone, so identical scoring matters more than a headline rating.
What a review method assesses, and what it leaves out
Evidence that counts as documented
A review here starts with material a reader can check. Published pricing, contract terms, support commitments, integration documentation and company filings all qualify. Vendor case studies are recorded as claims, not as proof. We do not open demonstration accounts, run trials or claim hands-on testing of any platform.
Every item carries a date and a note of where it was found. When a pricing page changes mid-review, both versions are logged with the date of each check.
What sits outside the method
Uptime, publisher quality and fraud controls are not scored from first-hand measurement. Neither are a vendor's finances or its road map. Third-party security certifications are listed with their issue dates, and we do not verify them. Naming those gaps helps a buyer commission separate checks, which is the sequence set out in affiliate marketing: reviews and comparison methods for 2027.
How evidence, claims and judgement are kept apart
A before and after view of the same review
| Field in the review | Before: claim-led write-up | After: evidence-led write-up |
|---|---|---|
| Price | Competitive pricing copied from a sales page | Figure, currency and page date recorded |
| Contract | Vendor summary of terms | Clause reference checked against the published agreement |
| Compliance | Fully compliant assertion | Dated enforcement example, or no claim at all |
| Performance | Screenshot from a vendor deck | Vendor-reported figure labelled as such |
Weighting and scoring without invented precision
Weights are set before scoring and published with the review. If a platform scores badly on support but well on integration, the reader can see which weight produced the total. A single overall mark hides that arithmetic, so totals here are shown as a range, not a decimal.
Support commitments are scored on what the contract states, not on how quickly a sales team replies. Response times quoted in a proposal stay as claims until a signed agreement repeats them.
Where two vendors score the same, the review says so. A tie is more useful than a forced winner, because the deciding factor is often the buyer's own publisher mix.
Due diligence that keeps a review defensible
Using enforcement examples as evidence
The ASA rulings database records how the regulator has applied the CAP Code, including cases involving affiliate and performance marketing. A ruling supports a statement about published enforcement. It does not prove how a platform behaves behind a login.
One ruling is an example, not a pattern. Where a review cites enforcement, it states how many rulings were found and the period they cover.
Checking the method against the market
Trade bodies matter for scope. The IAB UK's account of its own story and remit sets out which parts of digital advertising it covers. That helps a buyer judge whether a review's frame is wide enough. Scope questions matter most for small English teams, because a platform built for large networks may not suit a retailer with a handful of publishers.
Market direction moves between editions, so every market claim in a review carries its publication date.
Common questions
Does a review method replace a trial?
No. A documented method tells you what was checked and when. It cannot show how a platform performs in your own programme with your own publishers. Budget separately for a paid pilot if that evidence matters to the decision.
Can a vendor respond to a review?
Yes, and the response is published as a dated vendor statement alongside the assessment. It does not alter the evidence, and readers can weigh both.
Who decides what counts as independent evidence?
The reviewer sets the test, then applies it to every vendor in the comparison. Filings, published contracts, regulator rulings and dated industry studies count. A supplier's own deck, blog or sales call does not.
How often should the method change?
Review the weights annually or when the market shifts. Small wording fixes can happen sooner. Record the version date on every comparison so a reader knows which method produced the score. For a wider view of English providers, see affiliate marketing best providers in England.
