The majority of sites that I operate work off of the WordPress blogging script.  I have been unable to find a comparable website backend that stream lines my affiliate marketing.  Everything is made easier in Word Press due to it's huge inventory of plugins, which allow for simple tasks like adding Amazon products to posts or full on automated scraping of articles and products.

Below are the Word Press affiliate plugins I can't live without. (Affiliate links are used, thanks for your support.)

phpBay Pro ($79.00) - My online life has changed since finding this handy little affiliate plugin.  Basically the WP plugin adds items from eBay onto your blog and can be customized to fit your sites style.  Items can be inserted in a shop type manner or as a few items listed at the bottom of a post.  This plugin has great support directly from it's creator Wade and is under constant improvement and updates to follow the changes within eBay.  phpBay Pro works with the eBay Partner Network and with Pepper Jam Network.

Amazon Auto Poster ($29.99) - I've only started using this WP plugin about a month back and it's already paid for itself.  As you can tell by it's name, this plugin scrapes product listings at Amazon.com and then creats blogposts automatically.  The items are scraped per your keyword choices, starting point, and category.  The posts generated can then be scheduled up to 9 days out or published immediately.

Article Auto Poster Premium ($29.99) - Again, I just started using this plugin about a month ago and it's already provided me with additional traffic, sales, and profits.  Just like the plugin name says, it scrapes ArticlesBase.com for the keyword you choose and generates blog posts off the articles found.  Each keyword creates it's own job to publish a post based off of that keyword as often as you want.  This is a great method of generating long tail keyword search traffic and keep your blog updated when you cannot be bothered with writing content.

AD Rotator (FREE) - This free Word Press plugin makes ad management on your blog a no brainer.  You create a catalog of advertisements, which are then grouped by php code that you place within posts or on your theme files.  This will automatically rotate the ads you placed within the group.  Weights can be adjusted and there is no limit to the amount of ads that you use.  Great way to keep ads fresh on your site through multiple page views and try different affiliate products.

Closing Statement

I use a lot of different plugins with my Word Press blogs, but these are the ones that I can't live without and provide me the most commissions.  No, the majority of them are not free, but very quickly they can be paid for with just a little traffic.  Pair these WP plugins with a browser plugin like Affiliate Espionage and you'll see your weekly earnings rise.  It still takes hard work, but thanks to plugins our work as marketers can be streamlined.

Like any digital product your mileage may vary.  However, the items listed here I use on a daily basis and can vouche for their usefullness.  For more affiliate news and information please read my affiliate blog on Blogspot, where on my latest post I describe what makes a BAD landing page.

Update 7/2/09 - The Amazon Auto Poster and Article Auto Poster are now known as WP Robot.  I'm still on the fence on my opinion of the new wordpress affiliate tool.  First reactions is that there is only an option to schedule and not 'Publish Now', which makes it difficult to edit these posts before going live.  We'll see.
