Minimize your web page's size. The users with poor Internet speeds will have a tough time if you do not. You don't want your visitors waiting for each page to load because they may just end up leaving.
Use ALT tags whenever possible. These helpful tags describe an image to a viewer, assisting the visually impaired, as well as those who prefer to browse without images. As an added bonus, some search engines include these tags in their rankings, so you may get a boost by using them.
Avoid creating user interface (UI) controls that mislead your visitors. These controls include elements, widgets and more that create an interactive experience, such as a link, drop-down list or button. You do not want to make visitors think that clicking on an underlined word or phrase for example, will lead to a new page if it is not actually linked to something else. When your visitors have expectations of something working a certain way and it does not, they are more likely to assume there is something wrong with your site and leave.
Test your website before it goes live. There's nothing worse then launching your new website and having to take it down right away due to bugs or other issues. Get a group of people together who are using different web browsers and computer platforms, and ask them to use a beta version of your website, writing down any issues they come across.
