AdBrite's full page ads overlays your website with an advertiser's until you click on a button at the header to skip the ad. A while back I disabled AdBrite's Full-Page Ads because shortly after enabling it, I saw a significant traffic drop. Although it could have just been the natural order of things, I didn't want to take any chances. Traffic came back shortly after I disabled it, but again, it could have just been be the normal ups-and-downs of the the traffic cycle. I've read that since it's just javascript, it shouldn't affect search engine referrals which makes sense.
Like I mentioned in the Ebert article, I've been testing out ad networks on subpages of Wopular for the past couple months. I don't want to put any ads on the main channel pages until I've settled into something; also, I want to reserve those pages for premium sponsorships.
I watched Roger Ebert's interview on Oprah the other day where he revealed his new computerized voice put together by processing audio commentaries he did for DVDs. I went to his blog to see if he had anything to add, like he did for the Esquire article. Instead of a reaction entry, I got an entry inviting me to join The Ebert Club, which cost $4.99 for the year for some value-added services.
Last December, Alexa launched a new feature on their site - demographics. It measures the relative age, education, and gender of a site's users. It also measures where those users are browsing a site from (home, school, or work), and whether or not those users have children which is an odd statistic.
