verifying websites

Hello. I have an adult tube site on it’s own server with a separate web address that is running the open source WordPress software. Is there any way for me to post a code in the WordPress template to verify my site with those adult add sites that require you to verify your site with a code before you can receive revenue such as hubtraffic or popads? I have tried placing this code everywhere I can think of(plugins, widgets, main theme) with no luck. With hubtraffic, I can get the videos on my site, but they are pretty much useless to me as far as getting revenue from them because hubtraffic will not register the hits to me without verifying my site.
