One of the ways to drum up more business, is by way of your RSS feed.
You can add your affiliate links in the bottom, you can use partial feeds to make readers come to your blog so all links in the sidebar are seen, and you can use your affiliate links inside your posts to create extra sales.

Every time I watch a new movie, I link to it with an affiliate account inside one of my posts.
It sends readers to that affiliate link, and even if they don’t buy that DVD, they usually end up buying something else within a few hours, or even sometimes a full week later, depending on the affiliate cookie hold.

Using images inside your entries is a great way to hold your readers attention. A post with a picture tends to keep your readers on your blog longer than just text.
People like to look at things, especially items that you are reviewing, so they can really see it’s value.
The average consumer believes word of mouth marketing more than just the products description page telling you how great it is.
Real people doing honest reviews, makes people believe it more, and therefore, more willing to go out and buy the item themselves.

So if you are looking for a great way to boost affiliate sales, use pictures of the product you are reviewing, review it honestly, the good, the bad, and the downright awful.
People want to know it isn’t very good so they don’t waste money.
But if it’s great, talk up it’s awesome points, and watch those sales go up.
