How to tag users automatically based on clicks?

I think you meant to submit a Discussion item, rather than an Idea.

To do this, you would create a checkbox field and a smart campaign with a trigger and filters for the links they click.  If the combination of links satisfies your filters, the Change Data Value flow action would change the checkbox field from "false" to "true".

Thank you for your response. I will try out your suggestion.

I meant to submit a disccusion item. My bad.
