Before optimization. We observe a jump in the increase in the cost of applications during the launch of similar offers for the same audience by structure: separate offer - separate campaign.
After optimization. Since August, offers have been updated 2024 mobile phone number data combined into one common campaign (each offer is a separate ad in the common campaign), which has sharply reduced the cost of leads due to reduced competition.

Tips for optimizing your advertising campaign
— Combine new offers with current ones. Remember this when launching another offer to an audience that already sees our product or service.

— Launch a new offer for a different audience segment. For example, we advertise cars. If we currently have a car rental offer with interest targeting, then launch a specific car brand rental offer with retargeting for landing page visitors. Although there is a possibility of audience overlap, this approach will still significantly separate users and the auction.
— Use the “Inspector” function in Facebook. It will tell you how much your ad groups overlap in the auction. And it will give you a signal that it’s time to change something.
