How do you report on all footer link clicks within the past year?

We include includes to different resource pages in our commercial footer. We're looking to consolidate or replace some of those links, but first need to understand how many clicks we're seeing on each link. I pulled a link clickthrough breakdown report for the exact links used in the footer, but it's also pulling in clicks from outside the footer where those links are present, like in newsletters.

Any suggestions on how to best go about pulling a report on footer link clicks?
