Stop paying twice for the same shopper, and win back the ones who left.
Shoppers browse online, call the store, and buy in person, and each channel sees a different fragment. Marketing pays to reach people who already shop with you and misses the ones who left without buying.
Bituser joins web visits and store calls into one customer, deduped against your own history. Spend goes to shoppers you can still win instead of the ones you already have, and email, ads, and mail work from the same list.
