Right now, publishers do not have the option of requesting only site-targeted ads. The feature is still a beta and we are evaluating a number of options for the future. However, at this point, we believe that for most publishers it makes sense to request both site-targeted and keyword-targeted ads, because: (a) the competition between site-targeted and keyword-targeted ads will increase monetization for the publisher, and (b) the keyword-targeted ads will act as a backfill if at any point, there are no site-targeted ads available.Hopefully they will give AdSense publishers as much flexibility as they want. As for cases where no site-targeted ads are available, Google ads are nice and collapsible, so that can be easily avoided. Wouldn't it be nice if sites could choose to have a link for AdWords buyers to instantly bid on ads on that site? It's not for everyone, but some people might like it.
