Banner blindness is a phenomenon in which web users ignore advertisements due to their familiarity with them. Banner blindness occurs when users become so accustomed to seeing advertisements that they no longer take notice of them. This can be incredibly detrimental to affiliate marketing campaigns, as the goal of these campaigns is to get the user to click on the advertisement and visit the affiliate’s website. The most common cause of banner blindness is the use of too many similar advertisements. This can cause the user to become desensitized to the ads and ignore them, making it less likely that they will click on them. Additionally, if the ad is not eye-catching enough, users may not take notice of it, regardless of how well-placed it is on a website or blog. For example, let's say an affiliate marketer is running a campaign for a new product on a website with a lot of competition. The affiliate marketer places the advertisement on the site, but the ad is not eye-catching or unique enough to stand out from the other ads on the page. As a result, visitors to the site become desensitized to the ad and do not click on it. The affiliate marketer fails to generate any sales from the campaign due to banner blindness.
