If you’re happy to see all desktop and mobile performance data for your Price Check and Nudge Messages combined you can simply set up one message, ensure it has no 'Device type' audience targeting applied to it and then monitor the performance of just that one message.
Alternatively, if you would like to monitor the desktop and mobile performance of a message separately, you’ll need to duplicate your message and apply different ‘Device type’ targeting to each version. This approach has value because you'll get a clearer picture of how many visitors are seeing and interacting with your message across the two channels. You might find that one performs better than the other, and can take steps to further optimize the website experience for both types of guest.
Here's how to set up a desktop and mobile version of the same message:
Set up a message as you ordinarily would in the Message Builder. Go to the ‘Audience’ tab, select ‘Device type’ targeting and select ‘Desktop traffic only’.
Once you’re happy with the content and design of your message, save it as a draft then go back to the Message Manager and click the plus sign on the right hand side of your message to duplicate it.
Duplicating the Message will instantly create a new version of your message. It will have the name of your message and then ‘copy’ as the message name, so you’ll need to update that message name to help you easily differentiate between the two messages. It’s probably best to add ‘mobile’ to the name of the duplicate and 'desktop' to the name of the original version for clarity.
You can then go into the ‘Audience’ tab of your new duplicated message and switch the ‘Device type’ targeting to ‘Mobile traffic only’. You should then take a quick look at how your message will look on mobile in the ‘Design’ tab, and make any little tweaks required to ensure it looks as good on mobile as it does on desktop.
When you’re happy with both versions of the message, publish them and you’ll be able to compare the performance of your mobile and desktop message in the Message Manager.
