link labels best practice

Can anyone explain the best practices in regards to link labelling specific to usability/accessibility best practices. A 3rd party who do some basic maintenance of our website have numerous image based links on the homepage which simply state "click here". If you hover over the link it does give a bit more detail on where the links takes the user but I am still not sure that is sufficient, and the label itself should be meaningful, but I am trying to emphasis the risk in them using this kind of practice. I have seen these guidelines, but I cannot find anything specific in WCAG to link labelling best practices to assist users with disabilities e.g. visual impairments. I want to draw out the types of user this type of configuration could impact - to make them improve and use more appropriate labelling.

Just saying it 'looks poor' isn't having much weight in the argument.

Check out for a set of testers.

Run your site through several + these tools will give you a list of suggested site changes to make.

Tip: In the site change notes provided, you'll find a massive amount of data. I tend to just run a site through a few tools + clean up links, till tools report acceptable setup.
I'm using W3 validator this point what need to be changed to have valid code.

For the user experience, then it's depend of domain activity and who is going to use it.
If it's required explanation, this probably mean that it may need some adjustment to be more clear.
