I just wanted to ask that can we create multiple accounts with one credit card? Does Google allow this or the ad is stopped when you have 2 accounts with one CC?
I am not sure but I guess it will work, you should ask this question to google personnals or try it out yourself.
Google maintains a high standard for our user experience and the quality of our advertising. In order to preserve the quality and diversity of ads running on Google, we don't allow advertisers or affiliates to have any of the following: * Ads across multiple accounts for the same or similar businesses. * Ads across multiple accounts triggered by the same or similar keywords. Individuals advertising for themselves or for their own businesses may only have a single AdWords account. However, your account may contain multiple Ad Groups and ads triggered by the same or similar keywords. Only client managers (such as third parties or search engine marketers) who use a My Client Center can have multiple AdWords accounts. All associated accounts must be linked to the manager's My Client Center account. If you're interested in creating a My Client Center so you can manage multiple AdWords accounts for other people, you can sign up for Google Advertising Professionals. This program provides you with free tools and training to help you manage clients successfully. https://adwords.google.com/support/bin/answer.py?answer=8759&query=multiple+account&topic=&type=f
Ive had quite a few accounts with the same cc and all the accounts are still standing... im not using them anymore though.
I used to work for a company that managed PPC campaigns, and provided you use the MCC to access the accounts, there's no problem using the same CC/billing information ... ... we did it many times when the client's funds ran out and we graciously topped up the accounts for them ... (... of course it cost them a management fee, but there you go) H
