Action Logic: What is "add tag" and "remove tag"?
'add tag' is used on almost all surveys and will add an invisible Tag variable to the respondents in your condition.
Which you can then use...
- in your Survey Logic (e.g. When... respondent has tags), or
- as a Tag Quota when capturing responses in your channels, or
- to Filter your responses and analysis.
If needed, Tags can be tracked, charted and analysed in the Hidden Variables question type.
Finally, for whatever reason, you might want to remove tags from respondents so this action allows you to untag respondents on the rare occasion that’s needed.
