Jakob Nielsen, "Web Page Usability Guru", provides details about a study where 232 people were asked to look at thousands of web pages and their reading behaviour was looked at and it was found that the dominant reading pattern looks somewhat like an F. Basically:
- Users first read in a horizontal movement, usually across the upper part of the content area. This initial element forms the F's top bar.
- Next, users move down the page a bit and then read across in a second horizontal movement that typically covers a shorter area than the previous movement. This additional element forms the F's lower bar.
- Finally, users scan the content's left side in a vertical movement. Sometimes this is a fairly slow and systematic scan that appears as a solid stripe on an eyetracking heatmap. Other times users move faster, creating a spottier heatmap. This last element forms the F's stem.
The F pattern's implications for Web design are clear and show the importance of following the guidelines for writing for the Web instead of repurposing print content:
- Users won't read your text thoroughly in a word-by-word manner. Exhaustive reading is rare, especially when prospective customers are conducting their initial research to compile a shortlist of vendors. Yes, some people will read more, but most won't.
- The first two paragraphs must state the most important information. There's some hope that users will actually read this material, though they'll probably read more of the first paragraph than the second.
- Start subheads, paragraphs, and bullet points with information-carrying words that users will notice when scanning down the left side of your content in the final stem of their F-behavior. They'll read the third word on a line much less often than the first two words.
For those of you working in sales, inside sales or brand management, communication etc this kind of information would be invaluable in helping you design your messages.
