If you wish to fund raise for a particular charity or organisation , this is an easy way
If you use it as your search engine, every search will donate to your chosen organisation. You can enter the name of the organisation in the bar and press search. There are lists amounting to over 400 pages , so if you know the correct name, it's easier and much quicker.
Then all the searches you do will contribute .
I didn't use it for all searching but for regular sites visited it's as easy as any other search engine.
