Web pages have titles that describe topic or purpose. (Level A)
The intent of this success criteria is to provide clear & descriptive titles to the web pages so that they are understood easily by all users. This success criteria is helpful for visually challenged users, cognitive users, motor disable users & users with short-term memory. Titles of the pages will give a clear & concise picture to the user what the web page is about & what to expect on the web page. While 2.4.4 link purpose talks about the purpose of the link, it is a best practice to link to web pages using their respective page titles.
By reading the title of the page, user must understand the purpose of the page. Sccreen readers such as JAWS & NVDA provide a shortcut key insert+t to check the title of the page. If there is more than one tab opened, then user can just look at the title & identify which page he/she is working on. In addition to that, a unique title would also help the users to ensure whether they are on the right page/step. Moreover, providing unique title would help index the site properly by search engines.
