At first glance, WP Ninja Affiliate might seem a lot like the WP Affiliate Pro plugin due to the many similarities, but in testing I’ve found that in many ways, it is a more advanced version of that plugin. It does the things you’ve come to expect from WP Affiliate Pro, such as managing your affiliate links, adding cloaked affiliate links to your existing blog posts, and even provide you with click statistics.

In addition to all that good stuff, you’ll also be able to:

1. Assign Multiple Keywords – If you want to use multiple anchor text for an individual affiliate link, you can do so with this plugin.
2. Group Affiliates – Group your affiliate links for easy management.
3. Enjoy Smart Caching – This plugin uses a smart caching feature to prevent your blog from slowing down.

I also found that many of the functions are easier to do than WP Affiliate Pro. Also, in the time that I’ve owned this plugin, it has already seen updates, leading me to believe it is very well supported by the author. If you aren’t happy with your purchase for some reason, you have an eight week money back guarantee!

Overall, I am very happy with my acquisition of this premium WordPress plugin I plan on using it on a few of my WordPress blogs. If you find you are managing a lot of affiliate links on your blogs, I recommend you check out the WP Ninja Affiliate splash page.
