Web Accessibly Tip: Link Type Indicators
It is a good idea to inform users when a link goes to non-HTML content (such as a PDF file or Word document). It can be frustrating to activate a link and then realize that the link requires an external program or viewer. An icon (with appropriate alternative text) or text, such as "(PDF)", is sufficient. Because screen reader users commonly navigate by links, it is vital that the link type indicator icon or text be placed within the link, otherwise this information is readily available to sighted users, but not presented in the context of the link for screen reader users.
