This should be used alongside Selecting the winning ad variation.
Enter up to four Ad Variations here to calculate the version with the best return either for a fixed budget or per day.
With a fixed budget you may find that the advert that provides the best return per dollar may in fact be beaten if you remove budget limitations and spend to maximise gross income.
The opportunity costs / values are an indicator of what the best performing ad CTR and Conversion Rate would produce and also what the best advert from the fixed budget would be if the restrictions were removed.
