Are you sick of generating unwanted Google Adsense and Google Analytics impressions? Just install the Google AdSense and Google Analytics Remover WordPress Plugin. When you're logged into your WordPress blog, the plugin will prevent AdSense ads from displaying and the Analytics tracking code is removed as well. It will also create placeholders with the appropriate dimensions, for the removed advertisements.
