Before you start creating a banner
General rules for all banners:
- The banner must not be overly aggressive in the sense of vibrating and flashing – an aggressive banner refers to a design that changes colors, headings or other important graphic elements in a striking manner and very short time span (less than 1 second), which can disturb the user when working with the page.
- The banner must not contain vulgarisms or other unethical elements.
- The banner must not exceed the permitted data limits and must have the correct dimensions for the required position.
- The banner must not contain control components of operating systems and must not look like a system report. Must not use generally known graphic elements in a misleading way – for example symbol “play” for anything else than the start of playing multimedia content and so on.
- The banner must in no way interfere with the page or influence the behavior of page elements which are not a part of the advertising surfaces (banner). It must not change the page title or its main content, or arbitrarily adjust the entered URL without clicking on the banner.
- In file names must not be used any diacritical mark, space or any spe-cial character. Instead of space, you can use “_”.
- All versions of the banner and target URL addresses must be submitted at least two business days before the start of the campaign, if not stated otherwise.
