flash layer
Flash layer is a special advertising format of online advertising. It is similar to the pop-up banner and, like it, it overlays the displayed web page.
Flash layers can contain animations and videos in Flash format. They can also be used to perform interactions. For example, surveys. Flash layers appear spontaneously and overlay the screen display. There are Flash layers that cannot be clicked away and disappear after a few seconds.
In terms of format, Flash layers are generally large in size, but they can also be in larger banner formats. For example, as skyscrapers, super banners or wallpapers. Since they lay on top of the content, they attract a lot of attention and have high click-through rates.
