I posted this earlier in the "how do I?" section but thought it would be better over here...
How can I set up individual tracking links for all of our keywords that we purchase through google? I don't want just one tracking link for my PPC campaign but rather track the performance of each keyword. Has anyone done this and if so what are the steps to setting it up and to monitoring/tracking it?

I have a new site that will be launching soon and want to be prepared. I haven't purchased the urchin on demand, should I? Can you even do that now that google bought them and are offering it for free (on hold though)?

Any help would be great.
Thanks,
J
