It is possible to make money doing this, but it does take a strategy in order to do it. You need to use a second email address, because frankly, you will get a ton of email from the offers you fill out. I also recommend using either Roboform, or the Google toolbar; they enable one click filling out of forms. This saves the repetitive task of filling out surveys.
Now, surveys may not be for you, but for a lot of people getting a regular job is not really an option. They may have kids, or some other reason that they must be at home. I have calculated that with Roboform and
CashCrate and only doing the 100% free offers (no subscription necessary, no cost offers, etc) I am able to make an average of $12. Not too bad.
To make sure you are credited for every offer is to make sure you do exactly what their instructions say. For example, they have a loan offer that pays out $45, but the directions say that you have to complete the form, AND get approved and fully funded. That's asking alot. What I do is stick to the .80-$2.00 100% free offers. That works for me.
Frankly, I also concentrate on getting referrals. I asked two of the top earners on Cashcrate (people making over $2,000/month on a regular basis) what they did to get there, and they both told me they concentrate on getting referrals. One person said they only actively promoted for one month, and then stopped, and the checks just kept getting larger as her referrals started getting their own referrals.
Anyway, I have more
