Hi: I am using Google Adsense on my site. Based on the WP documentation, I got the impression I needed a plug-in to get the Adsense to work. Google's Adsense site also indicates that plug-ins may be required for WordPress self-hosted sites.
Is there reason I need to use a plug-in that may not be apparent from a visual review of the site? E.g. that I won't get credit for clicks or something?
