Blinking text can also be distracting and interfere with your site's message. Typos and misspelled words are sure to be spotted and are unprofessional. Some use of images is great as it will liven up your message and capture their attention. Huge image files seem to take forever to load on some computer monitors. Keep in mind that not everyone accessing your site has the latest and greatest equipment.
Color is important.
Like with images, it can add something important that will hold your customers attention. Background colors or patterns that make it difficult to read the text will make your reader go elsewhere for information. Business web surfers have very little patience for sites which appear to have little or no useful content. If they don't read something that tells them they have found some useful information on the first screen to screen and a half they will not stick around. Java or Java-script message can sometimes be seen as intrusive, often slows down loading, and sometimes is blamed for crashing a user's browser software.
