How people scan web pages

How people scan web pages


- The users usually scanned in the centre area first, then the left area and then the right column
- The users would only investigate the left and right column when looking for additional information
- The users quickly learned to look where they would expect to find relevant content and avoid areas which was unimportant to their current task, such as banner ads
- The users would only re-evaluate their scan strategies when they detected changes in the layout of pages
- The users where able to determine if surrounding content was relevant before looking directly at it, suggesting that peripheral vision plays a central role in the interaction with the web pages
- Ads attracted users only when they related to the current task – even if the content interested users
