It it really necessary that the article be split between multiple pages. At first I wondered, "where is the comparison" until I found the drop down menu...
this feels like a real problem that some startup should solve.
clearly, websites that do this are shooting themselves in the foot in terms of UX, for the sake of pageviews and ad impressions. Is there now better way?
When I worked for a publisher there was a long debate over UX vs page views and ad impressions.
I think Google has rules around how you can load ad's also so it might not be posible to do anything dynamic. Google has all the ad inventory so is the dominant player.
This makes me wonder further. Did you see higher bounce rates when using multiple pages? If so, did the ad revenue brought in by displaying ads across multiple pages out-weigh the higher bounce rate? Honestly curious about the pros and cons.
