Have you ever seen one of those websites that claimed you could make some extra cash by filling out surveys online? Maybe you've already signed up for one or two of these sites but were disappointed with the results.

If that's the case, here are 7 proven tactics you can use right now to boost your survey earnings.

Tip #1 - Join as many as you can

When it comes to online surveys, more is definitely better. While this may seem obvious, a lot of people overlook this simple step. You can't expect to supplement an income with online surveys by joining just 3 or 4 companies. You've got to join as many as you can to maximize your chances of receiving numerous survey offers.

Tip #2 - Know where to find them

Joining a bunch of survey companies will only work if you know where to find them. That's easier said than done, but don't sweat it, because I've already done all the hard work for you. My website (featured at the bottom of this article) lists all the survey companies you can join for free.

Tip #3 - Stick with it

The longer you stay with survey companies, the more chance you'll have of being picked for the higher paying ones. You must establish yourself as a reliable survey worker before you can receive those top dollar surveys.

Tip #4 - Set up a separate email account

Once you're signed up with all the survey companies you're going to receive many invitations. Your inbox will get full very quickly, so it's best to have a separate email account dedicated to your survey offers. This will ensure that you don't miss an invitation by accident due to a cluttered inbox.

Tip #5 - Sign up for prizes

Don't pass up a survey company because it compensates with prizes instead of money. Most people only care about cash rewards so they don't sign up to prize-giving companies. You can take advantage of that because it increases your chances of winning the prizes since there's less competition. Most of these prizes are cash prizes anyway.

Tip #6 - Stay close to home

Another mistake that I see a lot of people make is to try and join multiple survey companies in different countries. This doesn't work because most survey companies are targeting people in their own country, and not necessarily in yours. Companies wanting feedback on products in Cambodia are not likely to care what people think in Kansas.

Tip #7 - Don't be like everyone else

Finally, separate yourself from most idiots and realize that taking online surveys is a business. Understand that it will take time to generate a steady income. Don't join these companies and give up after a month because you didn't make a fortune. The money will build up over time, just have patience.
