How do I invest $300 in Marketing and Building Up an Affiliate Site?

I have $300, possibly more, that I'm willing to invest.

In the past I tried building a "review page" on a blog in order to promote an affiliate product from Clickbank and I used ezinearticles to promote my page. Unfortunately, it did not make much money, I was only about to make around $200 in a month or so.

I don't have a lot of time to put into this, but I do have the money as I currently run multiple sites that earn me a nice income every month. I make a nice income every month, but I know the sky is the limit for a successful affiliate.

Let me know if you can help me or direct me in the right way.

Thanks

 

spend $75 marketing your affiliates links through adwords.

 

Well, I still need to build a new site and get it all set up.

Thanks for the advice though, I'd like to hear more!
