Hyperlinks are elements within a document that link to another section in the document or to another source, such as a webpage, another document, a presentation, spreadsheet, etc. They are often preceded by "www" (eg. www.dvc.edu).
Just think of it from the perspective of someone listening to your document, instead of reading it. Ambiguous labels like "Click here" can confuse the listener as it is not clear where the link will take them once they click. Plus, JAWS may not read the link in order that the author intended, causing further confusion.
Accessible hyperlinks have a text description that will become the active link to the website or other document. Only listing the URL to a website (http://www.dvc.edu) as a link is not sufficient. Instead, a descriptive text label (i.e. Diablo Valley College website) is required.
It's fine to list a URL to a website at the side of a descriptive text label for a link. For example, "Disability Support Services at Diablo Valley College website (www.dvc.edu/dss)."
