The ads kept running.
Sales kept falling.

This ecommerce client had used other advertising providers before coming to us. They reported ROAS below 2 and sales still declining, so they tried a different team.

We began by reviewing the advertising account.

Were the audiences right? Did the ads explain the product's appeal? We checked bidding, tracking and the post-click purchase journey before adjusting campaigns.

We then reviewed three figures each period: ad spend, customers and sales. All these customers came from advertising, with no major price changes or extra promotions.

The client saw improvement within three months.
