Christina Laun from virtualhosting.com has pulled together some facts about design that are directly observable from eyetracking studies.

1. Text attracts attention before graphics. Make sure your website is designed so that the most important parts of your text are what is most prominent.
2. Initial eye movement focuses on the upper left corner of the page. Keep the habits of your readers in mind if you want your site to be successful.
3. Users initially look at the top left and upper portion of the page before moving down and to the right. Users generally scan webpages in the shape of an ‘F’. Make sure the important elements of your content are located in these key areas to keep readers engaged. 
4. Readers ignore banners. 
5. Fancy formatting and fonts are ignored.
6. Show numbers as numerals. Readers will find it much easier to find factual information on your site if you use numerals instead of writing out numbers.
7. Type size influences viewing behavior. Want to change how people look at your page? Change the size of your font. Smaller fonts increase focused viewing behavior while larger fonts encourage scanning. 
8. Users only look at a sub headline if it interests them. Don’t put in subheadlines just to stick to a particular format–make sure that they are relevant and interesting. You can also help yourself out by making sure they include keywords that will bring search engines to your site.
9. People generally scan lower portions of the page. Highlight certain sections or create bulleted lists so information is easy to find and read on your page.
10. Shorter paragraphs perform better than long ones. Keep paragraphs and sentences short unless context mandates otherwise.
11. One-column formats perform better in eye-fixation than multi-column formats.
12. Ads in the top and left portions of a page will receive the most eye fixation. Ads placed next to the best content are seen more often. 
13. Text ads were viewed mostly intently of all types tested. 
14. Bigger images get more attention.
15. Clean, clear faces in images attract more eye fixation.
16. Headings draw the eye.
    
17. Users spend a lot of time looking at buttons and menus. Because of this, you’ll want to put in some extra time making sure that yours are well-designed.
18. Lists hold reader attention longer. Use numbers or bullet points to highlight important information within your content. 
19. Large blocks of text are avoided.
    
20. White space is good.
    
21. Navigation tools work better when placed at the top of the page.
