Additional Ad Reduces Page eCPM

Further to our last post regarding the additional advert placed on the top of the page... we've removed it.

We can't figure out why, but the additional advert reduced the site revenues. That's right. It's not that it didn't make an additional money, it actually reduced the amount of money we made per page.

So it's gone. Probably for ever. Just goes to show how much we know about online advertising !
