Shop of alcoholic beverages - 1000% profit from the advertising price

Advertising has worked well. The goal was to find ways to improve its work. The customer had performance data for 6 months. The screenshot shows their performance before optimization. Moreover, many products were inactive due to some problems. I had to make sure that all the products are active and belong to the right category.
I identified search requests that didn’t bring conversions and excluded them, made an optimization of the campaign to increase sales, tested a new stake strategy and implemented it. ROI (Return of Investment) after optimization was 1000%. This is twice as much as before optimization. The monthly number of conversions increased by three times. You can see a comparison of the performance of the advertising before and after optimization and a report on the stake strategy. I can also show comparison of monthly revenue with the campaign.
