Yes and no. Affilimate both aggregates existing data from affiliate networks and programs, but also enriches that data and collects new analytics of its own.
Practically, you will be able to see transactions from all platforms as soon as you add your Integrations.
If your historical data provides landing page information, because the network happens to collect that, we will do our best to merge that with our analytics and backfill the information.
It is not possible to backfill this data because it does not exist until Affilimate adds and collects it.
