Advertising spending in Tanganica increases automatically based on meeting the target COS, so the best way to increase your daily spending is by increasing the target COS if the system is already meeting the target COS in the long term. Additionally, you can take advantage of advertising on other formats that Tanganica offers for advertising or by adding products that can streamline a given advertisement.
Also you can set custom budgets to your campaigns but this feature is only available for Tanganica Premium subscribers.
