A current, active e-commerce project with a display geography of the United States. Despite recent problems with Facebook, it is possible to work even with this region and achieve good results with the right approach and time investment.
The peculiarity of the work was that the materials for display (creatives) brought/bring results only on the first day/two, and after that they do not give any response, neither from twisted x2-x3 conversion costs, nor more. That is, in this case, you have to actively work on creating new content.

The event “Purchase” is a payment made directly on the website, with a certain value. The ROI in the project turned out to be unusual for eco-commerce, at ~140%. The ratio of expenses to income is clearly shown.

The best results were achieved when working with CBO, combined with a list of 100+ lines and values, with varying degrees of similarity.
