Client Profile

This seller is one of Germany’s leading brands in the health & supplements niche on Amazon. With more than 42 products, they have served thousands of customers in Germany and Austria. The company’s CEO grew his company from being a one-man show selling on Amazon to leading a team of 8 employees today.

In order to expand their sales channels and decrease their dependence on Amazon, the company created their own branded Shopify store. 


SOLID was brought in to help create an advertising strategy and drive more revenue through paid search and social media advertising.


Unpredictable sales:

Before working with SOLID, the company’s sales came almost exclusively through Amazon. Despite being a recognized seller with thousands of positive customer reviews and over €10 million in annual sales, Amazon would temporarily deactivate product listings or change rules that affected their product sales. The seller had already set up their own Shopify store and tried running ads, but sales through it were unpredictable and represented less than 3% of the company’s total revenue.

Low profit margins:

Coming from a competitive marketplace, the company’s philosophy is to provide the best quality products at affordable prices. This means that profit margins on each individual product are quite small. We had to meet a target cost per acquisition of 25% of the product’s price to remain profitable.

Concern for repeat purchases:

One of the CEO’s main concerns was that customers would not buy supplements from their brand again after the first purchase. He was unsure how to market to customers effectively to motivate them to keep coming back to their store weeks and months after the first sale.


SOLID helped create the online advertising strategy and created a multichannel advertising strategy with campaigns across Google and Facebook Ads.

We created multiple brand-focused and non-brand-focused Shopping campaigns, divided into single product ad groups to maximize control over keywords and bids for each product. For some of the top performers, we created separate campaigns to allocate a separate budget to them.

Across Facebook and Google, we implemented dynamic remarketing campaigns to run to site visitors who had added products to cart and viewed product pages, as well as multiple video campaigns for cold traffic.

When done right, dynamic remarketing campaigns are one of the key revenue drivers of successful E-commerce stores. Our partners and clients are always impressed with the high ROI they get from them.

Since working together, revenue from the brand’s own store increased by 102%, conversion rate increased by 6%, and conversions increased by 119%
