It's all a matter of opinion which one is best. I personally use the tools that I have on my own website to check my stats. You can try them at http://www.thepcline.com/website-analyzer-tools.htm I offer them for free. You can also try sites like seo central and the numerous webmaster tools offered by yahoo, google, and msn.
Headshot, I've tried your tool and it seems to be very helpful. Thanks a lot! I'll use it from time to time to see how my site is doing. Hope you don't mind.
I would like to check digitalpoint keywords tracker, but I can't find my API? How can I find it? Please help For meanwhile, I'm using ExactFactor - position checker
