Hi, What are your thoughts on the following in order to lower CPC/increase position on Google... I noticed that I get an excellent CTR at early hours of the morning (i.e. 3am - impressions are obviously very low)...the CTR gets lower as the day goes on. Therefore, would it be benefitial to daypart my Ads to show from 3am, till say 5pm? (as opposed to 5pm and onwards with low CTR) This way, some of the expensive generic KWs are getting high CTRs at the start of the day, and potentially benefiting from Google's Ad Ranking model. My question then...Is the volume of impressions taken into consideration when Google calculates it Ranking model, or is it purely CTR, Relevance and CPC? Thanks!
