When using Promotions, you may be wondering how Merch Jar comes up with the bids for the newly promoted keywords.
This happens in one of two ways, depending on whether or not there have been any sales.
Finally, if you have an amount or percentage modifier set, this will change your resolved bid by a flat amount or by a percentage, respectively.
Let's think through a few examples to better illustrate. Imagine you have two campaigns running -
You then have a promotion setup to
Let's say this promotion was triggered with a "funny tshirt" search term and that your auto campaign's bid was $0.20 and your manual suggested keyword campaign's bid was set to $0.30.
The search term had been found in both your auto and manual suggested keyword campaigns, with no sales in either. The resolved bid will be the simple average of the parent bids, or the simple average of $0.20 and $0.30, giving you a resolved bid of $0.25.
The search term had been found in both your auto and manual suggested keyword campaigns. Your auto campaign has $20 in sales, while your manual suggested campaign had $60 in sales. The resolved bid will be the weighted average of the parent bids, weighted by their sales.
So (($20 in sales * $0.20 bid) + ($60 in sales * $0.30 bid)) / ($80 in sales) = $0.28 bid.
