Remember one thing: There is no one "best" way to get referrals on GPT sites. There are many, many ways and almost all of them work on some level. I'm just going to share with you some of the ways that have worked best for me, and hopefully will work well for you. Here's a few methods that get the job done pretty well:
1. Make a website or blog. This is probably the best way to get referrals. If you're able to make a good blog or website and advertise it well, you'll get more referrals than with any other method. Make sure to put good content on your website or blog, it needs to be something that people are really going to be interested in.
2. Refer friends. If you have friends that you think will be willing to put in the effort that it takes to make money online, than by all means get them to join. Friends that you refer are the easiest to help as well, and remember - when your referrals do well, you do well.
3. Make fliers and/or business cards. This isn't too tough, pick a GPT site, write a little bit about it, slap your referral link on there and make some copies. Once you have the fliers/business cards all you have to do is hand them out of put them up around your neighborhood.
4. Be enthusiastic! When talking to someone about GPT sites, seem sincere and excited about them. Make the person you're talking to interested. This doesn't seem like much but it really makes a big difference.
5. Post on a few forums. Being a part of communities is a great way to get either your website link or your referral link out there. Just make sure that the forum allows banners/links in signatures.
6. Put your referral link in your email signature. If you're someone who sends out a lot of emails, this can get you a lot more referrals than you would think. You'd be surprised at how many people will click on that link.
7. Get your site on some search engines (for people who have a website). Getting your website or blog on major search engines like Google is incredibly important. The page for submitting websites to Google is Here. But getting your page on Google is only half the battle, getting it on the first couple pages of Google will get you many more referrals. The best way to do this is through link backs (getting other websites to link to your site). There are many ways to do this. Link directories are one way - basically they'll put your link on their directory for free if you put their link on your web page. If you're going to use link directories you'll need to make a links page on your website. I've found that it's worth it to do so. Another way to get link backs is by using social bookmarking sites such as Twitter, Delicious, Digg, etc. Register on these sites and submit your link to them. There are many other ways to get link backs in the aforementioned guide.
Like I said, these are only a few ways of getting referrals. You don't need to use all of them either, just use the ones that you like. There really are infinite possibilities - use your imagination! I'm sure you can think of some more great ways to get referrals.
