Tracking Keywords

Does anyone know of a tool that will tell me how many times a keyword or phrase is searched?

Thanks

The only real available one is inventory.overture.com

I normally use google.com/trends and I find it better then anything else available.

The only problem is that you dont get a number you get get a good idea of what you will be expecting when you get to no1 .

Say for example you have a page for one keyword at no1 on google just use that keyword as a bench mark and fin dout how much traffic to expect in relation to that word using the graphs displayed by google trends

u can use inventory.overture.com. digital point tool is also available.

Thanks for all your suggestions. Just want i'm looking for!
