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 Pageview 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.
You are able to rename your custom affinities via the Custom Attributes section within the platform, that can found in the Navigation under 'Segments'.
Simply click the attribute number according to your set-up, enter your desired name and select 'Save'.
These will now pull through into the segment builder with your specified name.
Within here you are also able to see:
