What are bid gaps and do we need to worry about them if we set Max Bids? Without taking into account eh CTR and the whole quality score thing, how do bids really work? If person in position 1's max bid is $1, position 2 max bid is $0.85 and position 3 max bid is $0.50--- how much are they all actually paying for click? Also, if there are only 3 people bidding for a particular keyword, even if I bid $0.05 my ad will still show in 4th position correct?
