Your Adobe Analytics numbers most often mismatch Google Analytics due to a misunderstanding of processing rules and metric definitions. Unlike Google Analytics, Adobe Analytics has more advanced pre-processing rules which can limit, increase or alter the scope of your data. Google Analytics does not have this. Additionally, your channel groups in Google Analytics don’t match Adobe Analytics as the rules for each group vary. You will need to have a deep understanding of the pre-processing and configuration of both platforms to solve this common issue.
