Even though many of us find them annoying, they are not going anywhere, anytime soon.
Banner Blindness Stems from the cognitive phenomenon of inattention
blindness (IB) in which users do not perceive or focus attention on stimuli with a low probability of containing task relevant information
IB for banner ads emerges because users do not expect task relevant information to be contained in banner ads
Banner ads can reliably be predicted to be located on the right side of a web page and to some extent on the top, above the navigation menu – so they are easy to avoid and are a prime candidate for IB. top ad
right ad
Study Objectives
If banner blindness emerges when users expect ads to contain a low probability of task relevant information, what happens when the task does not require specific information?
If the right side is more likely to have advertising than the top, is there more banner blindness for right side ads than top ads?
Is there an interaction between these two influences on user attention?
Method
Home pages of eighteen moderately popular web sites were presented with either a top or right side banner ad
Users were assigned either a goal-directed or a free-viewing task
Eye tracking was used to quantify how much users looked at each area of interest on the web page.

Summary
When users have a specific information goal, they only view page areas that are likely to contain relevant information. They have inattention blindness to other locations.
Users are more likely to expect advertising on the right side than the top of the page.
There is an interaction between these two influences◦ users will look at locations that are moderately
likely to contain ads, even in a goal-directed task. ◦ when users do not have a specific information goal,
banner blindness does not emerge.
Practical Implications Banner blindness emerges because users prefer to avoid
attending to advertising when they have specific information to look for – so fooling them by masking advertising is likely to lead to reduced brand preferences.
When users are free viewing, they are OK with looking at ads, so interesting, attractive ads can be valuable.
User behavior was different among the 18 home page designs. The reasons remain unclear but there may be valuable insights into how to design home pages to increase users’ willingness to view ads.
The increase in total dwell time was over 200 ms for unavoided banner ads. Over time, this can lead to significant brand awareness, familiarity, and preference.
