In order for MCF Data-Driven Attribution to generate a model for your selected conversion type, you must meet the minimum conversion threshold for the past 28 days. The current threshold is:
- 400 conversions per conversion type with a path length of 2+ interactions (i.e., 400 conversions for a specific goal or transaction, not a sum of 400 over all conversion types)
- 10,000 paths in the selected reporting view (roughly equivalent to 10,000 users, although a single user may generate multiple paths)
If you have enabled MCF Data-Driven Attribution but don't meet this threshold, you will see a notification in the Model Explorer, ROI Analysis, and Model Comparison Tool reports alerting you that a Data-Driven model can't be generated due to insufficient data.
Your MCF Data-Driven model is applied on an ongoing, weekly refresh basis. The model weights (visible in the Model Explorer report) are refreshed on a weekly basis and include a trailing time window of conversion history (currently 28 days).
Maximum number of interactions and lookback window
Up to 4 interactions within the 90 days prior to each conversion are incorporated into the model. If you have questions, contact your 360 support team.
Types of interactions included
All MCF Data-Driven models include clicks and direct traffic. If (1) you have asked your account manager to link your Campaign Manager 360 account to Analytics or (2) you're participating in the Google Display Network Impression Reporting beta, your MCF Data-Driven model(s) will also include impressions and rich media interactions.
How Direct traffic is treated
For each conversion, MCF Data-Driven Attribution removes the last 24 hours of inferred direct sessions, i.e., the model doesn't give credit to the Direct channel if there was a marketing activity that occurred within 24 hours prior to the direct session.
Gaps in data
If there are any gaps in your data, and no model for the time period could be generated, those gaps are filled with the most recent Data-Driven model. For example, if you drop below the conversion threshold for a short time period, MCF Data-Driven Attribution won't be able to create a model for that time period and will instead use the previous time period's Data-Driven model.
Insufficient data to generate a model
If the model doesn’t find sufficient data for a conversion type, the MCF Data-Driven Attribution algorithm will not create a model for that conversion type.
This can occur when:
- A large number of conversion paths considered for the model have a single touchpoint.
To verify that this is the cause of insufficient data, check the Path Length report to see if a large percentage of paths have an interaction count of 1.
- The specific path is so infrequent that the MCF Data-Driven Attribution algorithm cannot be statistically confident of the validity of the model for the selected conversion type (although the path is still valid).
- To verify that this is the cause of insufficient data, check the Top Conversion Paths report to see whether a high percentage of paths have a low interaction count.
- Configure your default Analytics Channel Grouping to collapse low-volume channel definitions into a single definition. This will result in fewer paths with low interaction counts.
Notifications in your reports
As you are using the MCF Data-Driven Attribution reports, you may receive in-product notifications about the availability of your Data-Driven attribution model.A Data-Driven model has not yet been created
- More time is needed to collect data for your selected conversion. For example, if you've recently set up Goals or E-Commerce Tracking, you may need more time to meet the minimum conversion threshold.
- There's a temporary lull in conversions for your selected conversion type, and you don't yet meet the minimum threshold.
If you continue to see this notification, it may indicate that your selected conversion type will not meet the minimum conversion threshold. Consider investigating a different conversion type.
