BlogAds: Costs Per Impression
Danny Carlton has put together a comparison of BlogAds prices compared to the SiteMeter traffic results for the blogs.
BlogAds traffic numbers–like any other metric–are a bit off. For example, I have several adstrips, all of which should have identical traffic since they appear on the same pages, and there is sometimes rather substantial deviation between them. Still, the numbers do update themselves regularly and are likely the better comparison point, since all sites don’t have SiteMeter.
Still, Danny’s numbers are worth a look for an alternate perspective.
