In order to achieve the ultimate goal of running profitable campaigns, one needs to learn to identify the right audience for the offer. Audiences are separated by different parameters such as country, device, OS and browser. Different audiences have very different tastes for banners, landers and offers. The thorough and scientific approach to identify the winner audience is to exhaust all possible combinations. This approach will easily produce ten over campaigns under each campaign group. If we are testing 10 offers in 20 countries, we are looking at hundreds of campaigns. This number of campaigns will make manual optimization very difficult. Unless you are highly trained to look at hundreds of rows of data to make precise and rational decisions, otherwise it is close to impossible to manage these campaigns. Even if you are trained in this, wouldn’t it better to invest your time and energy strategizing on optimization rather than doing monotonous manual work? Hence, we introduce auto-optimization to maximize personal creativity on strategizing. With auto-optimization, you will be freed from the tedious work to observe data and formulate hypothesis.
