I am also new in this business.But,whatever i learned i want to share with you.You should start promoting cpa offer if you have minimum of 10000 fans in your fan page. You can do this by updating the status of your fan page or sending out a mass message to all members. To update your status, put the text portion of your ad into the text field and copy and paste the link into the link box in the tool bar below the text field. Once your link is attached and your message is crafted, press submit. This status update will be sent to all of your fans? mini feeds and will be available for new fans to see. Don?t forget to mix your CPA posts with normal posts that fit in with the flow of your page. You want the fans to think it?s a legit page (which it is) not a spam page. Do the same for messages.
