Kunena has the following module positions within which you can place any joomla module, so to add Google Ads to your site simply publish a Joomla Google Ads module into one of these positions.
kunena_profilebox <--- The profile box at top of page that is were you see " share "
kunena_announcement
kunena_bottom
kunena_msg_1 ... kunena_msg_n, where n = number of messages in a page
These module positions are available for any type of Joomla modules and are not limited to advertising modules, anything that can be displayed inside a module can be shown inside of Kunena through these positions.
Sizing and available space should be considered carefully as large modules can consume significant portions of your screen real estate.
Although what u are trying to do may be possible if you HACK the right profile box and insert your code rather than using a module.
