The data in Additional Info Strings differ by Event Types. For example, the Event Type of ROI Landing Page Link Click will have different Additional Info Strings compared to ROI Landing Page Visit. Below is a key of the most common Event Types and their strings.  

You can change the names of column headers in your .csv reports via the segment builder. This comes in handy when exporting segments or utilizing Email ROI Segments, under the Campaigns tab. For example, in the segment builder you can change AdditionalInfoString1 to Link URL as it relates to an Event Type of Email Link Click. Remember, if you are viewing multiple Event Types, Additional Info Strings are not the same for all Event Types. Below is an example of changing the AdditionalInfoString1 column alias to Link URL by navigating to the "Column Order & Aliases" button in the segment builder.
