As in Amazon we ask for the Default Bid. What is the default bid of this PGN? What happens on the back end with your default bid is that if you input $1, we stagger this bid down as follows: 100% goes to the Exact Level, 75% to the Phrase Level, 50% to the Broad Level, and Only 25% to the Auto Level.
For you to get started with the least amount possible for your business, you can just push out PGN after PGN knowing that we will take care of the staggering.
Of course, subsequently, you can edit this threshold and this bidding strategy but for now, in my experience working with hundreds of customers in Zon Tools, this is a very good starting point.
