Multiple Adwords accounts - can you and why?

[Jon12345]

Can you have more than one Adwords account? If so, what is the criteria and why might you need one?

There is in fact a way to manage multiple accounts. The only things I've heard are that you may not run the same keywords in separate accounts. There is also some type of system where you can handle accounts as if you are providing a service to your clients. That way you can manage all the accounts in one spot. Look around the boards, this was discussed many of times.

There are two 'multiple account' settings that I'm aware of.

1. A 'linked account'. This is when two or more accounts are considered owned by the same advertiser. It's for companies with huge keyword lists and 1 account won't suffice. If the same keyword appears in both accounts, when a search is preformed, only 1 will show at any given time. These are very difficult to manage if they aren't set up properly because of 'keyword leakage' between the accounts.

2. My Client Center (http://www.webmasterworld.com/forum81/3655.htm ):
This is an agency login. You can have the same keyword in multiple accounts because each account represents a different company.
