I just read the rules and wanted to let everyone know I found that they have to be legitimate searches. In their "rules" it says that a charity will be taken off their list if the service is abused. This is what they have to say about legitimate searches:
We ask that you use this site honestly. As long as you use GoodSearch just as you would any other search engine, it's never a problem.
Fraudulent searching includes, but is not limited to, repeated manual clicks, the use of use of robots or other automated query tools, etc. This will result in the charity being de-listed.
GoodSearch should also not be used to repeatedly link to sites for which the URL is well known such as HotMail, ESPN, MySpace, Facebook, GMail, AOL, etc.
I think if we chose the PF as our charity, and then do a search for it every time we log on, that might be bending the rules a little. So, just make it a point to look up some new tidbit of information every day to earn the PF money through "honest searches." I looked up "Purple people eaters" yesterday. [;)]
