I am searching for a keyword "Rank Tracker" for Google/Yahoo/Bing that would track keyword movement of 1000's of campaigns/keywords on a daily basis. I need that tool/website to have a friendly control panel to show all those 5000 websites and maybe offer a filter feature for me to see the best performing campaigns and of course the worst ones. I don't mind if it is a desktop tool or cloud rank tracker. Anyone have any idea if such a tool is available? Thanks in advance..
