Site Types

There are a number different types of sites to make money, here are the different categories if you're a little confused:

GPT Sites (Get Paid To)
These are the most common money-making sites, where they pay you to complete 'offers' (usually around $1 each offer) that require you to do something - filling out surveys, giving them your email address, signing up to a program etc.

Free Gift Sites
These sites are my personal favorite, where you usually have to do 1 offer (it'll be either free or cost you around $3) and then refer 5 - 10 people. Upon doing this they will send you your selected gift ranging from iPhones - TV's - Cash. The best of these sites are 123StuffForFree and Xpango (see the reviews above)
These sites offer the highest rewards for the most minimal effort and are highly recommended

PTC (Paid to Click)
These sites pay you to view other sites or ads for a certain amount of time, they tend to pay less for each ad than a GPT offer but take for less time

Paid to Surf
This category includes Agloco (see review above), they pay you to use a toolbar which displays small ads while you surf and you get paid for it
