I'm a relative noob when it comes to Adsense etc, however I have a site that has 3 adsense ads that run pretty much across all pages (Header, showthread and footer)... Over the last 2 weeks, site traffic has been up and then averaged out at about 6000 unique per day, page impressions obviously in line with those figures...however...the eCPM has totally gone through the floor to the extent that I've dropped to below half of what I was making 2 weeks earlier. I have no idea what's causing this - I've tried everything I can think of, alternated the look of the ads, opened them up to advertisers etc, but still the figures are dropping daily... Any ideas/guidance ? Cheers
