Hi
1. Post view conversions ( also known as "view through conversions" | are conversions that occur after a user has seen an ad but not clicked on it) require few implementation tweaks. based on the scenario that where is that campaigns is being served . If the campaigns serves on web site than we can achieve this by certain implementation tweaks. Using campaign stacking concept which help us to identify the channel which user using to view that respective campaign.
Using campaign stacking plugin and eVar we can get numbers where we can justify the how many users view the campaign and successfully converted.
Scenario , user visit you website view cmp1 and left the website but after few days or hours he visit again but through different channel ( email or seo ) and got converted. Campaign stalking makes map (Direct>Email .. so on depending on the channel) and give credit to the first or last channel.
One eVar will be used to campaign stalking and other will hold the name of the campaign which later on correlated to get the report.
