Custom affinity attributes allow you to define affinities for a set of values not matching our pre-defined affinities. For example;
A fashion brand may be interested if a visitor has an affinity to a specific colour
A jewellery brand may be interested if a visitor has an affinity to a specific metal
A holiday brand be interested if a visitor has an affinity to a specific star rating of hotel
Once these are set-up, they can then be utilised within our Custom Segment Builder.
Custom affinity attributes are denoted by their 'slot' number: attribute_1 to attribute_9. You're assigning a value to a slot as a dimensional attribute.
Set-Up
There are two ways to set up custom affinities;
They can be mapped to a GTM variable directly in your Made with Intent Pageivew in the Custom Affinities section as per the below:
They can be sent directly from your codebase, or via a custom GTM tag. More information on this can be found here
Using Custom Affinities
Once set-up, custom affinity attributes can then be used within the Segment Builder and added as a condition.
In the segment builder, attributes will come through numbered 1-9 dependant on the number within the set-up. So it's important to know which number corresponds to which attribute. We will be working on bringing in the ability to rename these within the platform shortly.
