Developing a list of top engineering websites requires many hours spent on hundreds of sites, combing through links and libraries of information. In evaluating what makes a good website, it quickly becomes apparent what also makes a poor website. Sites that are slow to load (because of excessive graphics), difficult to navigate and, in short, take up too much of a visitor's time do not encourage a return visit. Some of these negative factors include:
Sites that require registration (in order to learn more about a user) generally require a password for a return visit. Many users forget or misplace their passwords, becoming frustrated when trying to enter the site upon a return visit.
One of the most common mistakes made by website designers is to bury or not even list company contact information. The best-designed sites make it easy to find their physical location, telephone numbers, and other contact details, even putting it up front on the home page. The worst sites omit this information altogether. And for companies with large catalogs, a search function is essential. In fact, the search function should offer multiple modes of operation, for example based on part numbers, application areas, and key words.
