The concept is to be able to modify the bid prices on google ads based on "conditions"
Example ... if google reports that I have had 5 impression on an ad today ... increase MAX CPC by 50% to move me to the top of page, position1, for this keyword.
We currently have over 50,000 keywords and updating bid through the day manually currently is a full time job. SInce google Ads Manager shows what keywords are receiving impressions & clicks ... it would make sense to modify bids to shift your positioning - placement for that keyword programatically
