Searching is one of the main ways to earn Swag Bucks. As you search throughout the day you will randomly be awarded Swag Bucks (which are like digital dollars). When you win there will be a box at the tope of the page that will tell you how many Swag Bucks you have won. Sometimes to claim your Swag Bucsk you might have to type in a Captcha (a few random letters in a box) to verify you are human. There is no limit on how many Swag Bucks you can win in a day! Though generally people win two or maybe three times a day.
If you see the Search Engine Sweepstakes rules it means that you are over searching (searching too fast or not searching real words and the system flagged you) and have been suspended from searching for a little bit. Sometimes you can start searching again in an hour, or sometimes it takes up to 24 hours for you to be able to search again. This really just depends on the system. If you were legitimately searching, just be careful in the future.
Your chances of winning do not increase by clicking on sponsored links that show up. Swagbucks.com should be used like you would a normal search engine and is designed to reward natural searching. If you do abuse the system, you will be shown the sweepstakes rules and then if you continue you risk loosing your account. So, just play fair and you'll be fine.
You can search using Swagbucks from either the main homepage or you can set the main search page as your homepage. What makes the the main search page nice is that it is a clean background and makes it look like a normal search engine. You also have the option to upload a picture and use that as a background on the site.
Using Swagbucks to search can be really rewarding over time. It might not seem like it at first, but the digital dollars do add up. I've been on there about 3 years and have earned just over $2,500 mostly in free amazon gift cards. Keep on searching, and you'll soon be trading your points out for wonderful prizes!
