But as I'm feeling in a good mood today I'll give ya some advice
decide what route you want to take with cpa.. Cpa is very very profitable if you commit to it.. But there's so many different ways to get conversions.. ppc, youtube, seo, social media sites are but a few of the methods..
As you're new I wouldn't recommend ppc as it's safe to say a fare few people have lost more money than they gained threw this.. Seo is a safe bet as it requires no investment other than hosting and domain name unless you decide to get free hosting. However most hosts tend to shut you down for content locking.. Plus seo can take a while to rank if you don't know what to do or what keywords to target... For a new person I'd say go with youtube or other social networking sites to get your feet wet.. These are the easiest way to get converts from traffic in my eyes!! I did say it's the easiest right?? Youtube you literally make a video or copy someones if you're lazy, rank it and and of you go.. With social media sites like twitter and fb.. It's a bit harder as they're ban happy if they sense any form of spam.. Plus you need to build up a following
Sit down and think about what method you wanna do as most people jump from one method to another when they first start. Whilst ya doing that read over these sections
They should give you a better understanding of how each method could work out for you
