Hopefully you guys have been signing up for these sites and finding great success! But I have some important basic advice for you guys in order to make the most of your experience!
1.) ALWAYS enter accurate information! If you don't, they can't mail you checks, your offers won't credit, and you can get BANNED from the sites if they consider it fraud!
2.) Use more than one email address, especially use one separate from your regular email for friends and business. You will get a lot of email from these sites, including paid emails, and you should not just delete them because they could be survey opportunities, etc. Also, make sure that you add the email addresses of all the sites you sign up to into your contacts. Otherwise, they might accidentally go into your spam folder.
3.) Pay close attention to the instructions for completing offers and surveys. If you don't, there's a high chance you won't get credited.
4.) Don't rush through offers or surveys. If you rush through surveys, you can easily get disqualified. If you rush through offers, it might not credit because you are not spending enough time on the pages for it the site to notice.
5.) For offers, make sure you get all the way to the end! It might seem obvious, but a lot of people don't realize that it will not credit if you don't get to a page that either says you're finished or says "Last Steps" or "Your prize has been reserved", etc.
6.) If you ever have a problem or question, don't hesitate to contact that site's Support Center. They are often very helpful and prompt in answering (InboxDollars usually gets back to me within an hour or so!) Anyway, it's always better to be safe than sorry.
I hope these tips have helped some people and I'll add more when I think of them. For now, happy money-making!
