I guess it depends on what you mean by "free" money... Nothing is free; time is money. Going by those axioms, PTC sites aren't really the best. The way you make a lot of money on those sites is to get a network of referrals under you. Now you can try to get referrals on your own by advertising your link on other sites, but you usually won't get many people signing up. A better option is to set up a website / blog that has links to several different PTC sites. You'll get more refs and on several different sites. But beyond just getting refs, you want to get "good" refs. Having a blog with a bunch of banners may get people to check out the sites, but unless they are also establishing a good base of referrals, they won't be making much money and eventually may just give up. To ensure that those who sign up under you are "good", you need to establish a relationship with them. Putting more info and / or tips on that blog is one way. If you can get them to become regulars on your blog, then when a new site comes along they'll be more apt to sign up under you for that site. `The best refs are those that you've established a personal relationship with. This means having e-mail and / or blog comments / forum conversations with them. If they feel that you are on their side, they will be loyal to you in return. When they are having trouble making money on their own, being there to support them and offer individualized suggestions will keep them in the game. But if you are going through all of this work, you may as well try to earn some extra non-PTC money thru your blog / website. Advertising or becoming an affiliate marketer can get you even more money on the side. Esp. if you become an affiliate for something that gets recurring purchases, your customers become like PTC referrals, except that instead of getting a percentage of a few cents a day, you get a percentage of a few bucks. Before you know it, you are making money not as a member of a PTC site, but as a professional blogger or web-site host.
