I want to make some ads to get some referals.
which is better ?

E-mail ads are more effective usually because you are actually paying for people to click onto the site.

thanks very much
but the fee of email ads is higher

I don't think so ,always people don't like these make money news!

I notice points paid, non-paid, and paid e-mails. Any advantage to what is used?

The points and paid e-mails usually have costs that are directly related to the amount of clicks that you will recieve. Some people only click on paid e-mails but some click on point ads also.

They are more expensive because they get better results than the banner impressions. With banner impressions you are just paying for people to think about going to your site.
