Swagbucks is a search site that allows you to rack up points which can be used for gifts or gift certificates. The first half dozen or more sites listed will actually be paid advertisers, but otherwise, your search will acoomplish what you want.
Here are some Swagbucks tricks and tactics that will rack up points more quickly.
Download and use the Toolbar that Swagbucks offers.
Don't overlook special offers provided on the home page. That includes a daily poll which can get you a quick point by responding to a multiple-choice poll.
My own experience is that you can score points most easily early in the day and late in the day by running a half dozen searches with four out of five turning up bonus points within that period. Swagbucks will only award points four or five times a day in all, so don't go in with excessive expectations.
Do not bookmark sites directly but instead bookmark the Swagbucks page with the link to the site you want to revisit.
Sign up friends and family. You will be awarded up to 1,000 matching Swag Bucks within 48 hours for searches they make. You win when they win during searches.
