i have a campaign going right now and some keywords are getting lots of impressions and most of my clicks but the ctr is very low. should i pause that keyword temporaily to get the ctr up for that ad group? for instance say im bidding on "auto insurance quote" and that click got me 9 out of my 10 clicks for a day. but that keyword is getting 1,100 impressions and only 9 clicks which makes its ctr .81%. In that ad group i have a total of 1,150 impressions. so if i pause that keyword that will bring that ad group to 50 impressions and 1 click which makes the ctr 2.0%. so now the ctr is 2% instead of the .81% but by pausing that keyword im only getting 1 click now. if i do that to raise my ctr will that make my qs also raise and my bid prices lower? then once my qs raises and bids lower i can unpause that keyword and will be in the top spot and get more clicks thus maintaining my ctr?
