If you're trying to raise money for charity, search engines can help. On a forums thread, JohnMu shares information about two Google programs that you can apply to for donations for specific causes.
The first thing he talks about is Google Grants which is advertising for nonprofits. "Google Grant recipients use their award of free AdWords advertising on Google.com to raise awareness and increase traffic" which translates to free PPC. Sweet.
The other program is Google Checkout for Non-Profits which processes donations by charging credit or debit cards for free (until 2009).
I'd love to know if there are other search engine programs out there. If so, share them in the comments.
