Use Links and Buttons Appropriately
Links and buttons can be scripted to perform various functions. In general, buttons should only be used when form data is being submitted or when other in-page elements are being controlled or manipulated. Links, on the other hand, should be used when a context change will occur for the user – such as going to another page or jumping to a content area within a page. Because links and buttons are identified differently by screen readers (e.g., “Search link” versus “Search button”), they should be used appropriately so it is clear to screen reader users what a particular link or button will do. For example, it could be confusing to use a scripted link to submit a search form – a screen reader user that hears “Search link” may think this link will take them to the search page when they are instead looking for a search button to submit the form.
