No real changes for some time. The single ad can be viewed on my Google SEO sig link. What does Vocational Rehabilitation have to do with search engine ranking?
" . . . on every page." Yeah, me too. I just tried Safari browser - same thing as Firefox. I think VR is finding new jobs for people who have been injured. Just a guess.
I see them running on some sites - and they are completely unrelated to the content. What's more, since the url contains uppercase letters, you can't ad block them. YPN has known about this problem with blocking urls with uppercase letters for months but haven't fixed it, so it may be intentional - a way to prevent people from blocking RON ads - probably because of a low inventory of ads compared to google.
If the ad is not paying good why don't you change your ad category instead, that may help. It is a know problem with YPN if there is no ads to show in that category you endup seeing same ads all over the page...give a try..
