Attribution & ROI Analysis:
How Do I Implement Multi-Touch Attribution?
Stand up clean identity and taxonomy, choose a fit-for-purpose model (W-shaped, time-decay, or data-driven), and validate incrementality so budget decisions reflect real impact.
Implement multi-touch attribution (MTA) by (1) standardizing identity and channel taxonomy, (2) capturing touchpoints across web, ads, email, events, and sales, (3) applying a declared model (start with W-shaped; evolve to time-decay or data-driven), and (4) reconciling with Finance monthly while proving incrementality through holdouts or geo A/B tests.

A practical, staged approach to deploy MTA and make it stick.
Step-By-Step
- Define revenue math — Agree on pipeline stages, bookings vs. revenue, sourced vs. influenced, and account ownership.
- Unify identity — Implement person/account IDs, consent flags, and account matching; enable server-side event capture.
- Harden taxonomy — Standardize UTMs, channel classifications, and program types; enforce via templates & QA.
- Instrument touchpoints — Map and ingest web, ads, email, events, partner, SDR touches; stitch with timestamps and IDs.
- Choose initial model — Start with W-shaped (first touch, lead create, opp create). Set lookbacks per stage (e.g., 30/60/120 days).
- Add alternatives — Layer time-decay for long journeys and pilot data-driven when volume and data quality allow.
- Reconcile & report — Publish an exec view across pipeline, bookings, ROMI, CAC, payback; add scope and variance notes.
- Validate lift — Run always-on holdouts or geo A/B for priority channels; document incremental results and confidence.
- Govern & iterate — Quarterly review of model weights, eligibility, and identity coverage; refresh as signals change.
Rule-Based vs. Data-Driven vs. Hybrid
| Model Type | Best For | Prerequisites | Pros | Limitations | When To Start |
|---|---|---|---|---|---|
| W-Shaped (Position-Based) | Milestone-driven B2B journeys | Identity, UTMs, CRM stage dates | Transparent; executive-friendly; fast to deploy | Credit ≠ lift; may under-value assists | Immediately |
| Time-Decay | Long cycles, late-stage nurture | Consistent timestamps; channel coverage | Rewards recency; balances multiple assists | Arbitrary half-life; tuning required | Phase 2 |
| Data-Driven (Algorithmic) | High volume & rich touch data | Event-level data, identity graph, QA | Learns patterns; adaptive weights | Opaque; needs scale; privacy constraints | When volume allows |
| Hybrid (MTA + Experiments/MMM) | Decision-grade budgeting | Testing framework; finance alignment | Credit plus lift; budget optimizer | Operational complexity | Scale stage |
Client Snapshot: From Credit To Lift
An enterprise software team launched W-shaped MTA with strict UTMs and server-side events, then layered geo A/B tests on paid social and brand search. Within two quarters, they shifted 17% of budget to high-lift programs, improved payback by 2.8 months, and aligned monthly with Finance on ROMI and CAC.
Tie your model to change management—publish scope notes, train GTM owners, and schedule quarterly reviews so attribution keeps pace with your sales motion.
