Companies use commercials to reach those who view television shows or watch videos on TV or online. Because it is easy to turn a channel, skip through recorded commercials or close a Web browser, those who make commercials must try to make their advertisements as compelling as possible. Advertisers employ a handful of techniques to reach target audiences and promote products

For website owners and businesses that rely on advertising income from their websites, this is obviously an important part of the website that needs major consideration during the design process. Not having enough space or the right locations for ads will have a dramatically negative impact on the business. Once that happens, attempts will probably be made to move ads or open up new slots for sale, which could cause the website to look awkward and unorganized, because these areas were not originally accounted for in the design. Websites with advertising revenue as their main source of income can be compared to e-commerce websites that depend on selling products in order to continue doing business. No designer is going to create an e-commerce website without making the placement of products, descriptions, and images in the layout a priority. Likewise, website businesses that require ad revenue cannot compromise on advertising space. Advertisements are also a significant part of the design process because of the impact on visitors. Although a website may rely on advertising income, visitors are a critical part of the equation. Without them, ad revenue disappears. The website owner and designer need to incorporate ads in a way that still allows for a positive visitor experience.
