With this blog I have occasionally used affiliate marketing to increase revenue on this blog.  Affliate marketing in my experience, can be both better and worse than payperclick marketing.

Some things to ask yourself when choosing affliate marketing:

1. Is the product related to your blog?  One of the best ways to take advantage of affliate marketing is to relate it to a blog post.  If you write about webhosting, what better than touse the affiliate marketing link to a webhost.

2.  Will I make more with affliate marketing? This depends.  I would recommend using affliate marketing links where you can, say when you recommend a good product and linking to that product on amazon, but as far replacing say that square 250×250 ad on your blog with an affliate only ad, I would recommend against it.

Using Affliate Marketing takes more time signing up for each link, but it can be profitable.  If you can link related affliating marketing links to your posts, you can generate substantial additional income.  Currently I have only done minimal affliate marketing, but even I would most liely benefit from using more affliate marketing links.
