A banner ad is an online ad on a web page that links to another website or landing page.
Banner ads were one of the first methods of advertising on the web. They have different costs depending on how much traffic and page views the website gets, and can cost from hundreds to thousands to even hundreds of thousands of dollars a month depending on placement.
Banner ads get their name because they are placed at the top or bottom of a web page. However, they can also be placed on the sides of the website content, also referred to as skyscrapers.
Microbars are small banners. There are also box ads. They are basically all display advertising.
Banners used to give effective exposure to websites, and have good click through rates. Now they have become such a common advertising method that consumers are believed to suffer from ‘banner blindness’.
So if you are thinking of using banners as a key part of your online marketing strategy, you might want to consider other methods that have proven more cost effective because more targeted, such as Google Adwords.
