Incrementality-Tested Attribution Retainer (14-21 days)
A productized engagement that pairs multi-touch attribution with a live incrementality test so agencies can defend budget decisions to clients with causal evidence, not dashboard screenshots.
- Client grants read access to ad platforms, CRM, and payment processor for the measurement window. At least 90 days of historical spend and conversion data exist in a queryable store. A named client-side owner can approve test holdouts and budget shifts. Agency has a documented methodology note ready for client-facing review.
- 1.Inventory every touchpoint source and confirm data freshness per channel
- 2.Map the client's revenue definitions (gross, net, recurring) to reporting lines
- 3.Agree on the single north-star metric the retainer will be judged against
- 1.Connect ad platforms, CRM, and payment data into the chosen measurement platform
- 2.Reconcile totals against the client's finance report and log every variance
- 3.Flag channels with broken UTM hygiene before any modeling begins
- 1.Build the multi-touch attribution model with an explicit credit-split rule
- 2.Document which touchpoints receive credit and why in a one-page methodology note
- 3.Run a parallel last-click view so the client sees the delta plainly
- 1.Select two channels for a holdout-based incrementality test
- 2.Size the test cells to reach directional significance within 21 days
- 3.Get written client sign-off on the holdout plan and spend exposure
- 1.Launch the incrementality test with geo or audience holdouts
- 2.Set a daily monitoring check for spend pacing and contamination
- 3.Brief the client's media team on what they must not change mid-test
- 1.Review first test readout for anomalies and sample ratio mismatches
- 2.Compare modeled attribution against observed incremental lift
- 3.Draft the reallocation scenario the data supports
- 1.Present interim findings to the client with confidence intervals stated
- 2.Propose one budget shift and quantify the expected revenue effect
- 3.Log client objections and the evidence used to answer each
- 1.Extend the model with a media mix layer for channels too small to test
- 2.Calibrate the mix model against the incrementality test results
- 3.Publish a transparency appendix listing every assumption and input
- 1.Build the recurring reporting template the retainer will ship monthly
- 2.Include a methodology section the client can forward to their CFO
- 3.Set alert thresholds for attribution drift and spend anomalies
- 1.Run the final test readout and lock the incremental lift estimates
- 2.Deliver the reallocation recommendation with dollar ranges per channel
- 3.Hand over the reporting template and methodology note to the client team
Clients renew when spend decisions are backed by causal evidence rather than platform-reported ROAS, and a single reallocation of 10-15% of a $200k monthly budget typically pays for the engagement several times over. The agency margin sits in the methodology and the recurring reporting cadence, not in the software license, so the retainer survives tool swaps. Transparency in the model becomes the pitch asset that wins the next client.
- Attribution model specification with credit-split rules and documented assumptions
- Incrementality test design and final readout with confidence intervals
- Channel reallocation memo with dollar ranges and expected revenue effect
- Monthly reporting template including a client-forwardable methodology section
- Data quality log covering UTM gaps, reconciliation variances, and fixes applied
The client has signed off on the attribution methodology, received a completed incrementality readout, and approved at least one budget reallocation based on the combined evidence.
