When people first see your site, the design is what grabs their attention… but the plugins are the backbone of your site and heavily influences the profitability and user experience for your web site. WordPress would never have become the platform that it has become today without being open source and allowing users to create and add their own plugins to make their blog do exactly what they want.

I’ve used a lot of premium plugins on many of my various sites, but these ones have proven most effective.

PopUp Domination This plugin is a must have for any blog that focuses on building a list or wants a larger newsletter subscriber base. I previously used Aweber’s lightbox to increase my RSS and newsletter subscriber rate, but since implementing PopUp Domination I have seen drastically better numbers. - Visit PopUp Domination

In short, this plugin is a redirect for your blog. You simply add in your affiliate url, then the name of your link and it will redirect through your blog, creating a very short link, while tracking click stats. - Visit Ninja Affiliate
