The standard Banner remains the most popular advertising format in CEE, but the highest average CTR is noted for Preroll, Toplayer and Interstitial – Gemius research shows.

The standard banner is used in 84 percent of all online campaigns run in Central and East Europe. A large share of this type of ads was observed in Latvia, Bulgaria, Hungary, Serbia, Slovenia and Lithuania. Standard banners are also frequently used in Romania, Croatia, Slovakia and the Czech Republic. The only exceptions are Poland and Ukraine, where the share of advertisements making use of this format in all campaigns served in that time is lower than the entire region’s average (i.e. 84 per cent).
