I have a website with Adsense on it: every page has a vertical banner on the right and a horizontal banner at the bottom. I'm using 2 channels to track the 2 banners. Until recently when clicking "Top channels" under Reports I would get the same number of impressions for each channel with CTR and all the stats. Now for some strange reason I only see the number of impressions for the vertical ad. The horizontal one gets just 10 or so (as opposed to 2k). Also no more clicks on the H ad. The only change I made - I replaced the 250/120 vertical ad with the 600/120. Anyone experiencing this?
Thanks.
