Add a custom attribution model

Analytics new

Needed permissions: owner, manage, edit & publish or edit

In Piwik PRO, you can use and compare the following attribution models: last click, position based, first click, last non-direct click, time decay and linear. If, for some reason, these models are not sufficient for your analysis, you can add a custom model. In this article, we’ll show you how.

Before you start

Before you begin working with custom models, we’ll explain what are the baseline models.

Add a custom model

To add a custom model, follow these steps:

1. Go to Menu > Analytics (new).
2. Navigate to Settings.
3. On the left, click Custom attribution models.
4. Click Add new custom model.
   

   

5. Name the model and choose a baseline model. For example, Position based.
   

   

   Note: The baseline model is the basis for building your own model. Each type gives you different options to customize the model.

6. In Visibility, set: Author or All users. The All users option lets you share this model with other teammates.
   

   

7. If you want to use this model on all websites, mark All websites.
   

   

8. Set up your model. For example, in the position based model you can use a percentage to distribute credit between interactions.
   

   

9. In Link credit to user engagement, select Session time or Page views in session.
   

   

   Note: This option is available in the following models: position based, time decay, linear. The channel that engages visitors more will get more credit. Engagement is measured either by session time or page views in session.

10. In Use additional credit rules, set additional conditions.
    

    

    Note: The credit for a channel that meets this condition will be adjusted by the factor that you set. For example, it will be multiplied by 10.

11. When you’re done, click Save.
12. Your new model will appear on the list. You’ll be able to use it in the attribution report and custom attribution report.
    

    

Use a custom model in the attribution report

To use the custom model in the attribution report, follow these steps:

2. Navigate to Reports.
3. On the left, click Attribution.
4. Navigate to Model comparison tool.
5. Click on the model picker, and the custom model will appear on the list.
   

   

   Note: You will find custom models in the same place in a custom attribution report.

6. Compare your custom model with other models.
