A GPT (get paid to) site lets you earn money for things you do already online. Such as reading an email, doing surveys, filling out offers, clicking on ads and getting paid for your time. Now you don't have to put any money out to do these GPT sites.
There are a few things you need to know before you can start doing these GPT sites.
1. Get yourself an email just for these sites. You don't want to use your main email account because you will get junk email from doing these offers or surveys. Typically you could use gmail if you already have it. If not you could use gmail, yahoo, inbox, or any other free email you know of. Just one that you will remember.
2. Only start out with 5 sites in the beginning so you don't get overwhelmed. Then once you get the hang of the sites then you can add more if you want too. Use the same email that you created above on each of the 5 sites you are going to be doing.
3. Use your real name, address and phone number. However, if you don't want to use your real number and you have a gmail account you can get a free google voice phone number that will be linked to your email. This I feel is a must to get. Do not under any circumstance put false information on any forms you may fill out. The advertising companies will find out and they will delete your account.
4. Read the TOS of the sites because some sites may want you to cash out on their site in order for you to get paid. This is very important.
5. Bookmark the sites that you will be doing so you will remember them and do them every day.
6. Make up a spreadsheet in excel to keep track of your earnings.
7. If you don't already have a PayPal account then you need to make one. Since some of the companies only pay you through PayPal.
I hope this has answered any of your questions on GPT (get paid to) sites.
