The index is the most common place users look when they want to find information online. Its purpose is to help them find what they are looking for quickly and easily.
Whether you're creating an index manually or using an automated tool, you'll want to fulfill the criteria for a good online index. A good online index makes access to the information as easy as possible.
Follow these guidelines:
Provide multiple ways to access the same information: Include many different terms that point to the same information. Include as many verbs and synonyms as possible to reach a wide range of users.
Include consistent access routes: Use inverted terms and headings (for example, X-Rays:Viewing, Viewing:X-Rays.)
Suggest entries users would think of: Devise numerous alternative words or phrases for doing things the user will look up. Think of your users' backgrounds and knowledge and consider how they would phrase their questions.
Provide enough detail to satisfy user needs: Strive for clarity by using enough description to aid users down the right path.
Ensure quick access to information: Users should recognize the term that matches their idea and go right to the information.
