You need to make sure whether Paypal, Alertpay and E-Gold are available in your country of residence.
Very few sites send check on requesting payout.
International sites or limited to certain countries
Some sites are restricted to certain countries. You may join these sites initially only to realize later that the site is not international. There are also certain sites which have ads based on your country of residence. Thus there may be fewer ads for one country and more ads for another country. Find out about such policies before joining the PTC / PTR programs.
Always Ask Before Joining A PTC Site
It is always better to find out the review of a site before joining. There are a number of new sites which keep coming up and some of these are scams. Thus if you are new with PTC's it is better to find out which sites have paid other users. You can get a lot of information about whether a site is legitimate or not from social websites and you can discuss with online friends whether a site has paid or not. It is really sad if you click and don't get paid on reaching minimum payout or if you joined a PTC program only to find that it has closed after a few days.
You can also find information on a number of blogs which give data as to which sites have paid along with payment proof. You will also find out other information such as minimum payout, payout policy etc. on some of the blogs.
Referrals
All sites will offer a package for purchasing referrals. Again before purchase of referrals it is better to find out the genuineness of the site.
As a rule of the thumb I don't advise purchasing referrals. May be at the most you can consider reinvesting a little sum earned from sites by purchasing referrals from them, though this may also not be advisable at most times. It depends on the risk appetite which you have.
You would not want to lose money in an effort to earn some.
Points
Some PTC / PTR programs give points for clicking on ads. There are some programs which allow you to convert these points into cash. Others allow you to purchase ads and links. It is important to find out how you can use the points and then decide whether you want to click on the ads giving points.
Finally it is important to devote time on a daily basis in order to be successful in the PTC business. So happy clicking.
