Most of us know the Digitalpoint Keyword Tracker tool. It’s really amazing. I use it for 2 years now I think.
But recently I wanted to research if any other similar, free tool exists on the web. And I found one: The Sitening SERP Tracker.
It supports unlimited websites, has a better structure and internal information organization than the DP Keyword tracker AND you have an RSS feed to better monitor your information:
It supports Google, Yahoo and MSN searches, using your own APIs, which you can get for free at their respective websites (they give an extremly detailed, step-by-step guide on how to get your APIs):
It has a daily/weekly/monthly autocheck feature (DP keyword tracker has it, but only the people who donated a small sum can have it activated), a better graph system, and a lot of other options:
Give it a shot and tell me how helpful it was.
