Overview
Screen reader users frequently navigate web pages, using the TAB key on the keyboard, through actionable items such as links, buttons and form controls.
...
Make sure that all links are provided at the point in the content at which they’re useful without visibibly displaying the URL or “here”.
Best Practice
Best practice is to provide descriptive actionable link text or button labels by default.
Avoid the use of single word links (“Here”, “More”, “Go”). Links should be clear, descriptive and able to stand on their own.
Good example: View all upcoming meetings
Bad example: View more
Good example: Start the process to apply for a marriage license.
Bad example: Click here to apply for a marriage license.

Use of aria-labelledby
You can also use the aria-labelledby attribute to associate the non-descriptive link text/button label ("Learn more..." "More..." "See more", etc) with the preceding heading.
...
In this example the screen reader will announce the Learn more link as “Learn more state of the city address”.

Email Links
Emails embedded in hyperlinks can be inaccessible because they often launch a user’s preloaded email client, which may not be what they use, instead of allowing them to copy and paste. It also may not be obvious what someone’s email is when a user is looking for it.
