I recently picked up a product about how to use article directories to promote CPA (cost-per-action) offers. It's a very simple concept. You write articles in the niche that the offer is in, and submit the article to the directories with a link to the offer or a landing page in your resource box. Since CPA offers can pay as low as $.50 per lead on up to over $100 for a purchase, this could be a very viable way to make some great money. The author says in the beginning you should direct link to the offer page to test the conversions. He also says if you don't want to build a landing page this is a great way to do it. My confusion comes from the fact that most of the popular article directories don't allow affiliate links in the resource box. Aren't these considered affiliate links? This is a good system because you can write an article outlining their problem and then direct them to the offer to find their solution. Once there, all they have to do is fill in a few spaces and click submit and you make $1-$3 on average. If you can write a good article with a high CTR and lots of traffic, you could theoretically make upwards of $20-$30 a day (if not more) from just that one article. I'm looking for input on this from anyone with experience, and also some ideas. Do the most popular directories allow this type of linking?
