If you have had numerous campaigns that have have lost money? Does Google take the overall history of your account in determining your Quality Score for future campaigns? It seems so to me If so, by creating a new account, will google link you to your previous adwords account? Say through credit card details, ip address etc.. and again will that affect your new campaigns? I know there are alot of other factors involved in determining QS, but I was wanting to know in particular from this stand point. Cheers.
