Part of Marketing attribution reviews: a gated test framework
Why no marketing attribution provider is named best: six candidates on HOLD
No marketing attribution provider is named best without a full dossier. Six candidates stay on HOLD, with the UK privacy, security and identity checks to run first.
No marketing attribution provider is named best here. Six candidates are named, and each sits on HOLD because the evidence file is incomplete. A best list needs a complete dossier, permissioned references and a controlled test for one England buyer job.
What to take away
- No provider is named best today. None of the six candidates below supplied a complete dossier, permissioned references and a controlled test for one buyer job.
- Those six entries sit at HOLD because the evidence file is incomplete, not because the product failed.
- For most England buyers the first move is the attribution already inside their analytics or CRM property, checked against their own ledger and the software selection method.
- Keep the manual process running until one candidate clears privacy, security, accessibility, contract and test gates.
The six candidates, all on HOLD
These are the products an England buyer is most likely to meet in a procurement round. Each entry is a candidate, not a recommendation.
| Candidate | Evidence status | First file to request |
|---|---|---|
| Google Analytics 4 | HOLD, baseline untested here | Property settings, export terms and consent mode record |
| Adobe Analytics | HOLD, no dossier | Exact edition and sub-processor list |
| Salesforce Marketing Cloud | HOLD, no dossier | Data roles for CRM records and England availability |
| HubSpot Marketing Hub | HOLD, no dossier | Tier that unlocks attribution reporting |
| Northbeam | HOLD, no dossier | Identity resolution method and missing-event handling |
| Fospha | HOLD, no dossier | Model version and stated uncertainty |
HOLD records that the required files were not returned. The attribution tools shortlist lists the evidence fields each row must fill before a name moves off HOLD.
Related products such as Customer Journey Analytics, Rockerbox and Triple Whale are not shortlisted here. One feature is documented for the Adobe candidate. Adobe Analytics lets analysts compare as many attribution models as they want, which supports a model-sensitivity test. A documented feature is still not an admitted candidate.
Default start for four buyer jobs
A default is the safest first test for a given job. It is not a ranking, and it changes once a candidate returns a fuller file.
- Retail and ecommercetest GA4 data-driven attribution against a merchant ledger before buying.
- B2B lead generationstart inside your CRM, because deals close over weeks and cookie-based tools lose the thread.
- Consent-sensitive sitestrial server-side tagging first, so consent state travels with each event.
- Large media budgetsrun marketing mix modelling beside attribution, because platform-reported uplift and modelled credit answer different questions.
Treat every default as a hypothesis. A candidate with a stronger evidence file replaces it.
What the price conversation should look like
No published rate cards were located for the commercial candidates at the research date, so every price is a quote. Put the volume cap, the renewal clause and the exit terms in writing before comparing totals.
| Pricing model | Where you meet it | Question to put in writing |
|---|---|---|
| Included with an existing property | Analytics-led tools | Does my volume still fit the standard tier? |
| Seat or contact-tiered subscription | CRM-led tools | Which tier unlocks attribution reporting, and what does renewal cost? |
A quoted range stays an estimate until it sits in a contract with a volume cap and a renewal clause.
The evidence pack that admits a candidate
One document should carry every field a reviewer needs. If a supplier will not complete it, the candidate stays on HOLD.
- Legal entity, exact edition and England availability, in writing.
- Inputs, identity resolution and handling of missing events.
- Output definition, model version and stated uncertainty.
- Privacy roles, sub-processors and transfers outside the UK.
- Security, accessibility, support, export, deletion and exit terms.
- One permissioned reference who supervised a comparable job.
Security answers stay claims until you confirm their scope and currency. A set of 12 supply chain security principles from the National Cyber Security Centre helps establish control and oversight of suppliers, but it does not certify any of the candidates.
Where a vendor refuses a full dossier, compare on what you can test: one fixture set, one window and one ledger baseline. The comparison methods page sets out non-compensating gates, so a failed privacy check cannot be averaged away.
UK rules tied to each evaluation step
- Supplier identityfree email alerts tell you when a company updates its details, so a filing confirms particulars, not the product edition.
- UK GDPR lawful basisyou must determine your lawful basis before you start using personal information, and you must document it. The ICO guide to lawful basis lists consent and legitimate interests among the options.
- PECR tracking rulesthe ICO guidance on storage and access technologies covers cookies, tracking pixels, link decoration, device fingerprinting, web storage and scripts or tags.
Before you shortlist anything, the tools and supplier guide explains how to judge a supplier by its admission file rather than its feature list. The vendor due diligence checklist records each answer.
Common questions
Why are all six candidates on HOLD rather than ranked?
None returned the dossier, reference and test evidence needed for one buyer job. Ranking them now would imply scrutiny that has not happened.
What should an England buyer do this week?
Send the evidence pack to two candidates and run the same fixture through GA4 and your own ledger. That gives a baseline before any purchase.
How do I compare vendors that refuse a full dossier?
Use one date window, one fixture set and a ledger baseline, then grade each candidate on the gates you can test.
