I am fairly new to Google AdWords and I was wondering if anybody can give me a hand on a bidding question. I see the majority of my conversions come during the hours of 7:00 a.m and 7:00 p.m. I was wondering if there is a way that I can lower my max bids automatically after 7:00 p.m and raise them again at 7:00 a.m again. I don't see any conversions after 7:00 p.m yet I am still seeing relatively the same amount of clicks.
