One of the main disadvantages of using PPC or CPM advertising is the fluctuation in revenues. The advertising network may choose not to display any advertisement or only show public service advertisements for which the publisher is not paid anything.
The payment methods used by the various advertising networks and affiliate programs depends to a large extent on the country in which the ad network operators are based and also their publishers.
Most US based affiliate programs and ad networks offer payment through Check, Paypal. Some also offer direct deposit in the bank account for US based publishers. For international publishers, direct deposit is available on payment of an additional fee.
Moneybookers is a popular money transfer system in Europe and has low fees compared to Paypal. It allows transfer of funds to bank accounts.
Compared to Paypal, Alertpay is new, but allows check withdrawal and wire transfer for a fee.
Liberty Reserve, Perfect Money, WebMoney and ePassporte are some of the other payment methods offered by Advertising Networks.
Since the web publisher is paid per 1000 impressions, the higher the number of page view your site gets the better it is for you, the Banner Network and the Advertiser.
All of the Banner Networks will first want to see your site before you are accepted. This ensures that neither of you waste your time. If one rejects your application, others may have slightly different criteria so do not give up. Apply to another banner network.
