Most people who surf websites don't think twice about the link they're about to click. The linked text typically says "click here." The web surfer assumes the link will load a page based on something seen earlier in the text.
However, if the web surfer is visually impaired, assistive devices such as screen readers will inform the surfer where the link will take them. When you use generic text like "Click Here" or "Read More" as instructions in linked text, it is confusing because the link says nothing about the content that will appear once the link is clicked.
Another thing to note: screen readers often tab from one link to the next. Tabbing between links labeled "click here" sounds like "click here, tab, click here, tab, click here" when read by an assisitive device.
As an alternative, consider changing the link text so it is an explanation of the target content. This will make more sense when read by a screen reader.
EXAMPLE
Original Instruction Text: Click here
Revised Instruction Text: Click here to read the latest news
