Create clear, descriptive and keyword rich links
Do this by properly identifying both the subject of the content, as well as an action which may result upon clicking. For example, as opposed to featuring a button or link which simply reads “click here”, create a link which says “learn more about accessibility for ecommerce sites”. This eliminates ambiguity, allowing screen readers and crawlers to correctly identify the link’s elements as well as providing clear description of what clicking the link will provide.
