22. If you are linking to PDF files disclose it: ever clicked on a link only to see your browser freezing while Acrobat Reader launches to open that (unrequested) PDF file? That is pretty annoying so make sure to explicit links pointing to PDF files so that users can handle them properly.
23. Do not confuse the visitor with many versions: avoid confusing the visitor with too many versions of your website. What bandwidth do I prefer? 56Kbps? 128Kbps? Flash or HTML? Man, just give me the content!
24. Do not blend advertising inside the content: blending advertising like Adsense units inside your content might increase your click-through rate on the short term. Over the long run, however, this will reduce your readership base. An annoyed visitor is a lost visitor.
25. Use a simple navigation structure: sometimes less is more. This rule usually applies to people and choices. Make sure that your website has a single, clear navigation structure. The last thing you want is to confuse the reader regarding where he should go to find the information he is looking for.
26. Avoid “intros”: do not force the user to watch or read something before he can access to the real content. This is plain annoying, and he will stay only if what you have to offer is really unique.
27. Do not use FrontPage: this point extends to other cheap HTML editors. While they appear to make web design easier, the output will be a poorly crafted code, incompatible with different browsers and with several bugs.
28. Make sure your website is cross-browser compatible: not all browsers are created equal, and not all of them interpret CSS and other languages on the same way. Like it or not, you will need to make your website compatible with the most used browsers on the market, else you will lose readers over the long term.
29. Make sure to include anchor text on links: I confess I used to do that mistake until some time ago. It is easier to tell people to “click here”. But this is not efficient. Make sure to include a relevant anchor text on your links. It will ensure that the reader knows where he is going to if he clicks the link, and it will also create SEO benefits for the external site where the link is pointing.
30. Do not cloak links: apart from having a clear anchor text, the user must also be able to see where the link is pointing on the status bar of his browser. If you cloak your links (either because they are affiliate ones or due to other reasons) your site will lose credibility.
31. Make links visible: the visitor should be able to recognize what is clickable and what is not, easily. Make sure that your links have a contrasting color (the standard blue color is the optimal most of the times). Possibly also make them underlined.
32. Do not underline or color normal text: do not underline normal text unless absolutely necessary. Just as users need to recognize links easily, they should not get the idea that something is clickable when in reality it is not.
33. Make clicked links change color: this point is very important for the usability of your website. Clicked links that change color help the user to locate himself more easily around your site, making sure that he will not end up visiting the same pages unintentionally.
34. Do not use animated GIFs: unless you have advertising banners that require animation, avoid animated GIFs. They make a site look unprofessional and detract the attention from the content.
35. Make sure to use the ALT and TITLE attributes for images: apart from having SEO benefits the ALT and TITLE attributes for images will play an important role for blind users.
36. Do not use harsh colors: if the user is getting a headache after visiting your site for 10 consecutive minutes, you probably should pick a better color scheme. Design the color palette around your objectives (i.e. deliver a mood, let the user focus on the content, etc.).
37. Do not use pop ups: this point refers to pop ups of any kind. Even user requested pop ups are a bad idea given the increasing amount of pop blockers out there.
38. Avoid Javascript links: those links execute a small Javascript when the user clicks on them. Stay away from them since they often create problems for the user.
39. Include functional links on your footer: people are used to scrolling down to the footer of a website if they are not finding a specific information. At the very least you want to include a link to the Homepage and possibly a link to the “Contact Us” page.
40. Avoid long pages: guess what, if the user needs to scroll down forever in order to read your content he will probably just skip it altogether. If that is the case with your website make it shorter and improve the navigation structure.
41. No horizontal scrolling: while some vertical scrolling is tolerable, the same can not be said about horizontal scrolling. The most used screen resolution nowadays is 1024 x 768 pixels, so make sure that your website fits inside it.
42. No spelling or grammatical mistakes: this is not a web design mistake, but it is one of the most important factors affecting the overall quality of a website. Make sure that your links and texts do not contain spelling or grammatical mistakes.
43. If you use CAPTCHA make sure the letters are readable: several sites use CAPTCHA filters as a method of reducing spam on comments or on registration forms. There is just one problem with it, most of the times the user needs to call his whole family to decipher the letters.
