A graphical web advertisement (usually 468 X 60 pixels in size) that is linked to the advertisers web site or offer page. Banner ads are one of the most popular forms of advertising online yet the effectiveness of banner ads is often debated among Internet marketing professionals.
 
Typically the more targeted or focused your banner ads are, the higher your click-through rates (CTR). Blind banners and banners promoting products or services to a broad-based consumer market will have lower CTR’s.

Banners that tend to outperform the average CTR are the newer, interactive, media-rich banners as well as creative standard banners placed in highly productive advertising networks.
