Making it hard to back up.
If user selected the wrong option, they should be able to return without any trouble to the previous web page. Part of your task is to make their life easier. Don’t let them leave your website because of this navigation error.
Being creative instead of being practical.
Practice creativity all you want, but don’t forget to address functionality. Fancy navigation effects may appear impressive in the demo, though they are actually more annoying than helpful. Flashing items and zooming text won’t help people go where they want to go. Remind your web design agency that your fonts must be readable, and have high contrast against the background.
Providing too much options.
People love lots of choices, but too much that it will overwhelm them. The rule of thumb in website design? Have only around seven choices.
Do you lots of generic labels such as “who we are” and “what we do?” These may be accurate, but obviously, they are not useful. Your labels must be specific enough, since users use effective search terms.
Misuse of drop-down menus.
Drop-down menus are not really bad for website navigation. In fact, they can help website owners organize details. However, if you fail to use it properly, they will surely have a negative impact.
