Click through tracking numbers seem low
In a recent campaign, we noticed that Eloqua reported significantly fewer click throughs than we saw as unique visitors on the targeted landing page (we use campaign trackers in our tracked urls in addition to Eloqua tracking (elqtrackID & elqtrack=true).
The discrepancies are significant enough:
Reported unique visitors from tracked link to the external (non-Eloqua) landing page (Adobe Analytics)
1,370 unique visitors
950 unique Eloqua click throughs as per Eloqua Insight
These differences seem consistent throughout. Is there a scenario in which an email click is blocked from tracking by the email client?
