Do links behind images help with SEO? Yes, definitely.
Internal links play a part in building link juice. And external ones help establish credibility, as well as helping the visitor.
They’re clear and easy to access, and users will probably click graphics first, since they prefer graphics to text.
Our SEO course
stresses the need to make sure the graphics contain alt text that
mentions the link, so blind or partially sighted people know what the
image is, and that a link is available.
But don’t use a graphic
link for the sake of it. Make sure it’s relevant to the visitor.
Otherwise, you may send them up a blind alley and lose them.
