Hi How long does it take a change in bid to take effect. I'm finding changing the wording of an ad can be immediate but there seems to be quite a delay when i change a bid. Yesterday my campaigns were sitting too high at number 1 and i kept reducing the bid and nothing happened then overnight the campaigns had disappeared onto page 2.
It seems to take a bit longer lately for bid changes to take effect. I've seen anywhere from 5 minutes to an hour.
