i have got a keyword that's not completly relevant to my landing page but this keyword generates a lot of searches. i used to advertise for this keyword with a cpc of 80 cents. it's a high search volume keyword and my ad received over 10,000 impressions daily,with only a few clicks tho. Google then punished me 3 days later by asking me to bid a minimum of $5 for this keyword and there're only 3 advertisers bidding for it. i don't want to give up this keyword as it has actually generated some sales for me and it's less competitive. now i wanna do this keyword again but i have to set the cpc to at least $1, and the qs is poor. i know with a poor qs i wouldn't go too far so i'm thinking of opening a new adword account,building a new landing page with a different domain for it. is it worth doing it? any opinions?
Don't make another account. in my opinion just increase your quality score. and then try with a fair price. why you wish to catch a visitor that has no interest with you website, how can you make business with them. try genion interest use, they may be low in visiting, but roi will be high. you need business or you need visitors, you decide.
Why are you not starting a new campaign for this keyword and same landing page or copy of same landing page? don't open new adwords account as google consider two diff. account running same landing page campaign and put them on fraud case.
