Description: The link text is generic text that does not identify the link purpose. The link does not seem to have any programmatically determined link context that can aid in identifying the purpose either.
Context: Information about the link can be provided in a number of ways, such as grouping it with a relevant header, including it in a paragraph with context, or adding an ARIA property such as aria-label.
<a href="http://manoa.hawaii.edu/careercenter/career-fair/" class="btn btn-lg btn-success" role="button">Learn More</a>
How to fix it: Link texts should be written so they make sense out of context. Generic texts such as “Click here” and “More” give no indication as to the destination of the links.
