When it comes to writing reviews that will capture attention and convince prospects to purchase through your affiliate links, there are two things you absolutely need to keep in mind. You need to write reviews for...
a) The search engines who read it.
b) The people who read it.
Obviously, you first write for your visitors. After all, it’s them that will make the decision to purchase through your affiliate links after reading your content. But you also have to write your reviews so that they are fully optimized within the search engines.
You do this by incorporating your keyword (including product titles) into your content and page title but also keep in mind that you should integrate keywords into Title Tags, Page Descriptions, Meta Descriptions and Anchor Text.
You also want to make sure that your reviews are easy to read and attractive. You need to capture and retain attention, so consider incorporating product images (such as image of book covers, or product boxes). Not only will this give your visitors a visual of the products you are promoting, but it will also increase perceived value.
When creating your reviews, you want to keep in mind that your job is to ‘inform your reader’.
You want to cover as many important benefits and features of each product as possible, while keeping it targeted and straightforward. Consider writing casual style reviews that make your readers feel as though you are talking directly to them (like a friend, recommending a product that you genuinely believe will help them in some way).
You want your reviews to come across as if they were written exclusively for the person reading them. That way you can personally connect with your audience and demonstrate to them that you have their best interests at heart.
Be honest. It’s important to push the positive to maximize your profits, but you also want to be transparent about any misgivings you may have or how you feel the product could be improved.
(This is also a great place to insert your bonus offer that could bridge that gap and "complete the product you are promoting!)
Also, write very detailed reviews, rather than basic summaries. People can find those anywhere and it’s likely they’ve already read the product sales page. Again, they want more than that. So go through the product with as much detail a possible, and break down the product into segment so you can touch on important benefits and different aspects of the products.
Creating powerful reviews isn’t rocket science, but it takes time to learn how to create compelling reviews that really touch base with your visitors.
