In August, the CPM rose for all formats except videos and 300x600 Banners. The biggest change was recorded for 300x600 Banners whose CPC fell from 27 CZK to 17 CZK. This is the lowest CPC this format has had over the past year. The CTR for videos increased from 0.69% to 1.30%, and the CTR for Mobile Skins has also continued to climb.
In July, video ads were the cheapest they have been this year (CPM 126 CZK). CTRs for Mobile Skins have been steadily climbing since March (2.31%). As far as HbbTV formats, more click-through campaigns have been sold, thus CTRs have been rising rapidly and CPMs for TV banners have been decreasing. July’s average CPC for HbbTV banners was 15 CZK—the cheapest so far this year.
