1. Automatically reduce the CPC to the actual bid and place my ad to the No.3 slot (I don't want my ad to show above that position).
2. If the ad below me raises its bid, mine will be raised accordingly to maintain the 3rd position.
2. If the max CPC of the ad below me is set to above $5.00, it will replace me to show at third position (provided that it wants exactly the same No.3 position). My ad will disappear from search.
Is the above true? I don't see much discussions on the Position Preferences feature here. So please share your experience or opinion on this. Thank you.
There is a bit more involved in your last scenario... there are complications that involve things like CTR and/or Quality Score, but assuming the competing ad is to rank higher than yours, your ad would indeed disappear.
