Google Analytics
Enough Said. I just use it on all my Money sites.
Fresh Metrix (Rank Tracking)
Easy rank tracking for national and down to the local level. You can start for free and
they have plans all the way up to the thousands of keywords.
Serpfox(Rank Tracking)
Nice & easy tool for rank tracking. Just plop in your URL, keywords and location and it
will do all the tracking for you. They have a free plan as well if you’re just getting started.
Serpbook(Rank Tracking)
Similar to serpfox but with nice white label and automated reporting.
I learned something today. I use this tool call Rank Tracker Tool. It tracks keyword position, alexa ranks, competitors etc. I like the automatic reports best. See http://www.ranktrackertool.com
