Jakob Nielsen heeft een top 10 samengesteld van webdesign fouten in 2005. Sommige staan al jaren in de top 10.

1. Legibility Problems
2. Non-Standard Links
- Make obvious what's clickable: for text links, use colored, underlined text (and don't underline non-link text).
- Differentiate visited and unvisited links.
- Explain what users will find at the other end of the link, and include some of the key information-carrying terms in the anchor text itself to enhance scannability and search engine optimization (SEO). Don't use "click here" or other non-descriptive link text.
- Avoid JavaScript or other fancy techniques that break standard interaction techniques for dealing with links.
- In particular, don't open pages in new windows (except for PDF files and such).
3. Flash
4. Content That's Not Written for the Web
Writing for the Web means making content: short, scannable, and to the point (rather than full of fluffy marketese).
5. Bad Search
6. Browser Incompatibility
7. Cumbersome Forms
8. No Contact Information or Other Company Info
9. Frozen Layouts with Fixed Page Widths
10. Inadequate Photo Enlargement
