Managing your adverts on a WordPress blog becomes a pretty simple thing thanks to the great little WordPress plugin entitled Advertising Manager from developers Scott Switzer and Martin Fitzpatrick. Basically it allows you to manage and rotate your Google Adsense, AdBrite, Adify, AdGridWork, OpenX, Yahoo!PN and WidgetBucks (amongst others) adverts on your site – all from an easy to use settings panel that even allows you to place ads in a sidebar through the use of a widget!
It provides a simple way to import your adds, allows you to place adverts straight into your blog posts with a click of a button, has functions to facilitate placing adverts directly into your template files and even goes as far as allowing for advert limitations by author, category, tag and even page type.
Oh, and it also features auto-recognition for 15 ad networks which basically means you can manage these adverts directly from your WordPress blog instead of going all the way through to each website!
