This is a direct selling advertising question.
For those who advertise what kind of information do you ask publishers before advertising on their website. I have seen places list Alexa rank, Compete rank, Del.icio.us bookmarks, inbound links, Facebook fans, Pagerank, etc. but does this information provide you as an advertiser with any REAL value. If so which ones you feel are crucial and which stats am I leaving out that you would normally like to see ( excluding monthly impressions and monthly unique visitors ).
I find Alexa rank or Compete rank shows no real tangible information, but I may be wrong.
Your input would be greatly appreciated,
