Search for a Cause allows you to raise money for charity each time you search because our search partner Yahoo has agreed to share the revenue earned from each search. That revenue from Yahoo is what we use to support our non-profit partners.
Unfortunately, Google is unwilling to share its search revenue, so it is impossible to raise money for charity by searching through Google.
We understand that switching search engines can take some adjustment, but we'd encourage you to give Search for a Cause a shot for at least a few days before deciding if it is for you or not. To emphasize just how impactful it can be: on average, someone who is using both Search for a Cause and Tab for a Cause will generate four times as much for the causes they are supporting than someone just using Tab for a Cause!
