This script comes from the fine folks over at Site Expert. (Oooooo, they even have a color chart.) Using this tool, you can check to see how many indexed backlinks lead to your site in such search engines as Google, Yahoo, Bing, and a number of others.
The cool thing about the tool is that is actually gives you the numbers on the result page. Some link popularity checkers only give you the links to the search engines themselves or make you jump through hoops to get the report. This tool actually shows you the number of indexed links back.
So tell me how it works. Feel free to brag about your link popularity numbers in the comments if you want.
