According to this report from the Nielsen Norman Group,
Our report on designing websites for senior citizens includes the following usability guideline:
"If using web or browser-related terms, consider defining them in place. Avoid using them if they are not necessary." [emphasis theirs, not mine]
Many users today understand standard web-related terms. But, in this study, many seniors were unsure about web terminology, such as page, homepage, website, or the web.
Some of the points and questions seniors made about web-related terms:
- “Is this a website or a web page? I don’t know the difference.”
- “I don’t know what ‘URL’ means. What is that?”
- “I don’t always know exactly what the word ‘web’ means.”
- “Is the homepage part of a website?”
- Another user couldn’t find an item on a particular page and said, “I don’t think I see it under this site.”
If these users were being confused by terms like "web page" and "URL," it's likely they'd be confused by a word like "field." So, if you're expecting a significant number of your users to be seniors or inexperienced with computers, this report suggests that it would be best to avoid that word.
