I only run 1 ad unit per page. So today there are pages without any ad units. And the epc triples. Which makes me want to put ad units back, but I know that if I do the epc will drop again. I have noticed this on numerous occasions. When I first started using adsense I placed 1 ad unit on 1 page. When I realized the value I obviously wanted to place ad units on every page. The more ad units/pages that I make available the less the value. Even though the ads are typically the same on each page.
