Issue
Reporting on separate links in an email that both point to the same URL
Solution
When there are duplicate links in an email, the performance of those links will be consolidated into a single row in the Analytics report, so if there are three links that point to the same URL, there will only be a single line for that link on the Performance report.
If you would like to differentiate between these duplicates, you can add URL Parameters.
Example:
www.google.com and www.google.com?parameter=second-link
In this example, Marketo Link Performance Reporting will show each individual link on Analytics Reporting, but both links will go to the same place.
