Technical specification of ad formats

Synchro Branding

Synchro Branding is a combination of strong branding with another format (480x300 or 300x600 or 480x480). This means that your message essentially dominates the most prominent ad formats on the page, greatly increasing the impact on users.

Before you start making a banner

General rules for all banners:

The banner must not be too aggressive, in the sense of jitter and flicker - 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 vulgarities or other unethical elements.
The banner must not exceed the allowed data limits and must be properly sized for the desired position.
The banner must not contain operating system controls, must not look like system messages, and must not use well-known elements in a misleading manner - such as the "play" symbol for anything other than turning on playback, the [×] cross symbol for anything other than closing / ending. magnifying glass symbol for anything other than searching / zooming, etc.
The banner must not interfere in any way with the page or influence the behavior of page elements that are not part of the commercial area (banner). They may not change the title of the page, or its main content, or self-modify the listed address without clicking on the banner.
The file names of the supplied banners must not contain any accents, spaces, or special characters. An underscore "_" can be used instead of a space.
All banner versions and target URLs must be submitted no later than two business days before the campaign begins unless otherwise noted.
