There is a 31 day free trial on our bronze level Rack Tracker. If you decide it's not for you, cancel the subscription before the trial is up, and you will not see a charge.

It's highly recommend that you run a keyword report before you run rank tracker, but not mandatory. Not only will a keyword report make the rank tracking tool easier to use, but you'll be able to see which keywords customers search with the most so you can make better tracking decisions.
