I don't have any paid subscriptions at this time, but I'm considering Majestic. Actually, the only reason I'm considering it, is because I have Long Tail Pro, and Spencer Haws uses data from it, so I'm assuming it's pretty nice. I would like to be able to do link research, and I'd also like to be able to track my ranking for select keywords over time, that way I can optimize my content, and see the improvements over time. Recommendations? I've got one site - Thanks!
