Website Usability Guidelines

Follow these usability recommendations:

Standardize Task Sequences. Use the same format for all user functions across all pages.
Reduce users workload. Let the computer perform as many functions as possible. This allows the user to concentrate on those functions requiring human input.
Do not require user to remember information from place to place on a website. User can remember relatively few items of information for a relatively short period of time. The working memory capacity tends to lessen even more as people become older.
Minimize page download time. The best way to facilitate fast page loading is to minimize the number of bytes per page. Pages must download less than 5 seconds, less time is preferred.
Display data in a directly usable format. Most users will not convert information. Present information in a manner that is consistent with the standards most familiar to your target users.

Format information for reading or printing. Prepare pages in a format that your user is expected to use them. You may want to provide both a reading and printing format.
Provide feedback when user must wait. Indicate to user the time required to download a document or imagine at a given connection speed.
Use users' terminology. Use terminology that your user is familiar. The average user reads at a sixth grade level.
Do not have unsolicited windows or graphics pop-up to users. Unsolicited windows, pop-ups, and non-meaning graphics are annoying and distracting to users.
Increase website credibility. You can increase credibility by:
- Provide user help file
- Provide FAQ
- Provide company information
- Provide contact information
- Ensure that website is up-to-date
- Ensure website looks professional
