Here is a collection of dashboards that I generally promote to clients because they can be immediately put into operation. All you have to do is replace the sample data set with your own personal data. These are copyright free. Just understand them well before using them.

Content Performance Sample Dashboard
If you are working for a content site that really needs to know how each landing page performs, I have used the above dashboard to start the conversation with a client many a time. This dashboard has several filters that allow you to segment the traffic and judge performance accordingly. You can copy this report from this link.
There are a lot more dashboards and reports that other people have shared with me so if you need something more specific, drop me a line here and I will get it for you.
