How do you charge clients for your Adwords work?

I have recently been negotiating with a client for creating an Adwords account and populating it with targetted phrases, split-testing of adverts etc.

When you are dealing with clients and are providing them with reports to show progress, do you take a screengrab and remove the keyword phrases so that the client can't use them and create a new campaign himself, so cutting you out of the deal?

Do you also have a clause where the client can purchase the Campaign at the end of your contract for a set price?

Just wondering how you guys structure your Adwords business so that clients can't take advantage!

Thanks

 

Initial free of 15$ and 15% of the spending

 

I tend to work on a minimum contract period. 3 months for local clients. 6 months for national clients. The pricing model has a number of components. A set-up fee. A flat management fee. And a spend related fee.

 

I managed over 80 clients. Set up fee plus 15% spend fee. Different fees for different projects.

Month to month no retainer obligation. I also grant admin access to the clients/boss email so he can review the AdWords/AdCenter accounts and he can keep it after I leave if he wants. The client should be able to see exactly what you are doing in the PPC campaigns. I teach them how to do monthly reports that suits their needs, so I don't have to.

If they bail out, I no longer update their campaigns.
