Well I wish it was just advertising inventory but I have a page that always shows RON ads. I cannot even get the category targeting to work on this one page. The other 282 pages of the site have no problem with targeting. The website is about Santa Fe, NM and the page that is stuck is Santa Fe history. I think YPN still has some bugs and there has to be something on the page that stops them from crawling the page. I have emailed them about the problem and they have it on their list to look at. I recommend you do the same if you have pages that get only RON ads.
