Before you go into CPA Arbitrage, you should know what CPA is and why is it so important you should jump on the CPA trend today. CPA stands for Cost Per Action. This means anytime you send a visitor to the affiliate offer, the visitor doesn’t have to swipe his card out in order to make you money. It can be as easy as signing up for a dating offer that would pay you $3-$5 for each person that signs up. This is why CPA is a better choice to the traditional affiliate model where you would get paid only when you refer a sale to the merchant. Also, you can find multiple offers to promote in a network. You don’t have to sign up with 10 sites to promote them, you just need to be signed up with one affiliate network and you will have access to different niches and different offers.
Alright .. How do you make money out doing CPA ? Here’s an example:
Eharmony affiliate offer
You see how simple and easy it would be for a person you send to this page to sign up .. this would make you $4-$5.
How to promote it ? There are a lot of good ways to promote an affiliate offer. If you live in a big city, just build some flyers and spread them around. You should make your own website and redirect it to the affiliate offer. Place an ad in the local classifieds newspaper. Post an add at the busy metro stations .. Plenty of offline marketing ideas to go around.
However, let’s focus on the internet marketing a little bit. Who is interested in signing up with Eharmony ? Well, let’s see… http://www.quantcast.com/eharmony.com
Now you have some very valuable data to start with - (% of female users, % of male users), age of users and most important what other sites they enjoy visiting.
You should understand why we are doing this. CPA is a very fierce competitive field. We need to break it down and find areas that we can exploit easily. We could pay $5 per click in adwords everytime someone is searching for dating, but that’s not too profitable 
So, if you’re targeting single males for instance, you will find that not only you can find single guys on dating websites but you can find them in different areas you wouldn’t expect. Do you think single guys play computer games a lot ? Do you think single guys enjoy watching sports and comment sports ? Do you think single guys mostly use their computer at night as they are alone and feeling blue ?
You need to research your niche properly before starting to market a CPA offer. You will find it’s very .. very .. rewarding :).
To your success. Gabriel
