Doubling conversions and value in a month

The client reached out with a problem, specifically he was not satisfied with the results of the current contractor's work. From my side, an analysis was conducted, during which I discovered critical errors.

The main ones are incorrectly calculated profitability, incorrect segmentation, errors in tracking statistics, as well as improper training of advertising campaigns.

After that, I carried out comprehensive optimization and refinement, thanks to which, literally within a month, the account showed nearly double growth — with the same budget. The client was very satisfied with the result, and we continued our collaboration. By the way, there is a positive review in the profile.
