It's well worth taking the time to view this video, as it will make attempts at increasing accessibility more focussed and successful.
A very interesting introductory article about screenreader technology. What I like about the video is that it assumes no prior knowledge of how a screenreader linearizes the page, and it explains not only how the page is handled by the reader, but also how a user interacts with the program and uses the features such as isolating the list of links to navigate and comprehend the contents of the page.
