Ad Placement Template Customization

If

(1) You want to place ads on your site, and you are not using OpenX powered Central Ad Server to serve your ads.

                OR

(2) Layout and size of one or more of your ads do not meet IAB standards.

Your YACG PLUS template needs to be modified to incorporate your ad codes or affiliate links.

On the other hand, if you use only cloaking to monetize your site, OR there's no ad on your site - no ad code or affiliate link, then there's no need to modify your template.
