As an aside to this experiment, I have been on holiday for the last 2 weeks and not added to my site at all.

Over the time the ecpm plummeted to quite low levels - 1/2 normal. This could be entirely owing to the Christmas / new Year season.

However yesterday was the first day I worked on the site and today my ecpm has returned to its pre chritmas levels.

I wonder if making changes to your site registers with google who reward updated content with higher paying adverts?
