# Comparing Tags
The **'Comparison Tags'** function allows you to select any tag and compare individual statuses. This function is extremely useful, especially during A/B testing, where you want to assess which version of a message performs better.
This is particularly important for marketing campaigns, and automation, where you can check the effects of that communication over time by tagging a particular type of message, such as an abandoned shopping cart. Similarly, for transactional emails, you can tag a particular message type. For example, select 'order confirmation' or 'invoices' and see how many messages have been delivered, opened, clicked or bounced
⬅️ **Detailed instructions for each panel section under the 'Comparing Tags' tab can be found in the dropdown menu on the left.**
