I am wondering what formats and page placments all you guys on this thread are using to find yourself in such low CTR/$ situation ... while january normally always is much down compared to december - my this years january had the smallest low - only about 5% less than dec and since i am now almost done with converting my entire site into the desired Google formats large/medium rectangle ATF - and the wide skyscraper in addition my CTR PLUS eCPM went day after day UP with each new section I have converted to meet the needs announced in G's last mail sent out - the CTR went UP hence it seems to me that G might push those three published successful formats among advertisers as well and may be less and less advertisers campaign on ANY format and more and more use the tragetable channels among these 3 formats ? it might be interesting to hear WHO of you low CTR guys has actually converted the last few weeks his entire site to the ATF placement offering rectangles ATF ??? for me - with still some 25% of my flat-file pages to be done - most of the converted pages now enjoy a 2 digit CTR vs a mit 1-digit CTR before .. and the site wide ctr average now is VERY near a 2-digit - with a site having a huge bunch of totally different topics
