I have this one account which has currency as GBP. Now the problem I am facing is - min bid is 0.01£ (not 0.01$). It doesn't look a big difference (since exchange rates very close) but when I am spending 20£ a day - with USD currency I could have had another 200-300 uniques (say at 0.01$ cpc) Anyone having same problem/issue - how did you get over it. I am planning to close this one and open with USD currency.
Yes, asy you cannot change currencies of your Google Adwords account, you will have to close it and reopen a new account in USD. Bizlord
