MerchantAdvantage was one of the first self-service feed platforms created in the early 2000s. In the last 5 years, it seems like nothing new has been added and it’s in maintenance mode.
MerchantAdvantage requires long-term contracts and charges based on data load fees.
Feedonomics on the other hand provides full-service, with 24/7 support, and doesn’t’ have long-term contracts. See a full comparison of the Best MerchantAdvantage alternatives and competitors here.
