I use My Search Funds for all my searches.
If you are prepared to Ask rather than to Google, you will be paid for each search you make. My Search Funds is free to join and easy to set up. You can also search from different computers and mobile devices with MSF, and get paid.
Your earning show up the next day in your MSF account, up to the end of the month. You get paid monthly to your bank or PayPal account.
If you get your family and friends to join, then you get paid a little extra for all their searches. You can make £20 or more per month, so it is worth doing. It could pay for your broadband or internet connection each month.
If you like using sites like Wikipedia, use MSF instead. The results will bring up a direct link to the Wikipedia page you want and you get paid for your search, as long as you don't try to abuse the system. You must do genuine searches if you want to be paid.
