About the programme
Course Overview
Last-click reporting hands nearly all the credit to paid search and direct traffic, so budget drifts towards the channels closest to conversion while the display, social and content activity that actually built demand gets defunded. First-click attribution makes the opposite mistake. This course teaches multi-touch attribution modelling as a practical discipline: building heuristic models such as linear, time-decay and position-based weighting, then moving to data-driven methods including Markov chain removal effects and Shapley value allocation that credit channels based on their real marginal contribution to a journey. You will design the tagging and identity resolution needed to capture a complete cross-device touchpoint history, validate attribution output against incrementality or geo-lift testing, and translate the findings into a revised media budget. The course finishes with how to present attribution results to budget owners who care about return on marketing investment rather than modelling technique, including how to handle the objections of channel owners whose credit falls once a fairer model is applied.
Expected Learning Outcomes
Build heuristic attribution models including linear, time-decay and position-based weighting for a multichannel journey.
Apply algorithmic attribution methods such as Markov chain removal effects and Shapley value allocation to touchpoint data.
Design the tagging and identity resolution architecture needed to capture a complete cross-device touchpoint history.
Validate attribution model output against incrementality or geo-lift test results to check the credit assigned is realistic.
Translate attribution findings into a revised media budget allocation across channels and campaigns.
Present attribution results to budget owners in a format that links channel credit to return on marketing investment.

01The Limits of Single-Touch Attribution
2 sessions · 8 points
Session 1Why Last-Click Reporting Misleads Budget Decisions
- Trace how last-click attribution assigns all credit to the final touchpoint, typically paid search or direct traffic.
- Identify the upper-funnel channels, such as display and social, that last-click reporting systematically undervalues.
- Reconstruct a sample customer journey to show how different attribution rules change the credited channel entirely.
- Explain why first-click attribution carries the opposite bias, overweighting discovery channels and ignoring closing activity.
Session 2Choosing Heuristic Attribution Models
- Apply linear attribution to split credit evenly across every touchpoint in a recorded journey.
- Apply time-decay attribution to weight touchpoints closer to conversion more heavily than earlier ones.
- Apply position-based attribution to weight the first and last touchpoints while distributing partial credit to the middle.
- Match a heuristic model to a business context based on typical journey length and number of channels used.
02Building Data-Driven Attribution Models
2 sessions · 8 points
Session 1Markov Chain and Removal Effect Analysis
- Construct a transition graph of channel-to-channel movement from raw touchpoint sequence data.
- Calculate removal effects by measuring how conversion probability changes when a channel is removed from the graph.
- Convert removal effect scores into normalised attribution credit for each marketing channel.
- Interpret Markov-based attribution results against heuristic model output to identify which channels were previously mis-credited.
Session 2Shapley Value and Game-Theoretic Allocation
- Explain the Shapley value concept of fairly dividing conversion credit among channels that co-occur in a journey.
- Calculate marginal contribution by comparing conversion rates across possible channel coalition combinations.
- Apply Shapley value attribution to a multichannel dataset using a spreadsheet or analytics platform function.
- Compare Shapley and Markov chain outputs to check whether both methods agree on which channels are undervalued.
03Data Infrastructure for Accurate Attribution
2 sessions · 8 points
Session 1Tagging, Tracking and Identity Resolution
- Design a UTM tagging convention that consistently labels campaign, channel and creative across every touchpoint.
- Deploy server-side or first-party tracking to reduce touchpoint loss from browser tracking restrictions.
- Apply identity resolution rules to stitch anonymous sessions to known contacts across devices and channels.
- Audit touchpoint logs for gaps, duplicate events and mistagged campaigns before they distort the attribution model.
Session 2Validating Attribution Against Incrementality
- Design a geo-lift or holdout test that measures the incremental conversions a channel generates without it running.
- Compare attribution-model credit against incrementality test results to identify channels that over-report their impact.
- Adjust attribution weights or exclude channels where correlation with conversion does not reflect a causal effect.
- Document the assumptions and limitations of the chosen attribution model for stakeholders reviewing the results.
04Turning Attribution Insight Into Budget Decisions
2 sessions · 8 points
Session 1Reallocating Media Budget by Channel Credit
- Translate revised channel credit into a proposed shift in media spend across the working budget.
- Model the expected impact of budget reallocation using historical response curves for each channel.
- Sequence budget changes in phased steps to avoid disrupting channels with long sales cycles or delayed effects.
- Set review checkpoints to confirm reallocated spend is producing the conversion lift the model predicted.
Session 2Reporting Attribution to Budget Owners
- Build a channel performance dashboard that shows attributed conversions, cost per acquisition and marginal return.
- Frame attribution findings around the business questions budget owners ask, such as where to cut or add spend.
- Prepare a briefing that explains model choice and confidence level without requiring the audience to follow the underlying maths.
- Anticipate objections from channel owners whose attributed credit falls and prepare incrementality evidence to support the change.
