Amazon Advertising Growth: 17% Growth in monthly sales in the last 6 months

Supplements and vitamins make a significant part of the health and personal category on Amazon. So, with tens of thousands of listings, this category is very competitive. Saying this, many brands are finding success in launching new products in this category. How do they find their success? It is down to time, investment in advertising plus promotions, and a long term vision. 

We have been working with a startup supplement company based in London, Iperk, since the beginning of 2021 to increase their Amazon sales via advertising. The results – 17% Monthly sales growth.

As an Amazon advertising agency, Online Seller UK works with both start-up and established brands. Get in touch to discuss how we can help.
