WP Power Stats

I like this plugin very much. Plugin is Simple and easy to understand. Most things that I use are "Visitors & Page Views" graph and "Traffic Source".

Useful stuff!

What a pitty: search engine keywords stay empty.
And I know that there must be a lot of them because I crosscheck it with Google Webmaster Tools.

No search engine keywords

Discover your visitors in real-time, intuitively and with style.
