I'm trying to get up to speed with how DoubleClick/Google manages display advertising. DoubleClick has its Floodlight tag, but Google Universal Analytics now supports display:
https://support.google.com/analytics/answer/2444872?hl=en-GB. Is there an overlap in functionality here?
. Does the Analytics tag supercede the DoubleClick one?
I've inherited a website smothered in third-party JavaScript libraries, so I'm looking to do a little pruning!
