Welcome to the Q&A Forum

What we do is add explanatory content to the tag pages that are for key concepts for our website and link to them from a "glossary" page—people who are new to some of these terms can go there for definitions. We also link to the relevant glossary page in posts where the term comes up, helping to create good internal linking. Other tag pages can be noindexed or just ignored—the Moz report is just for your reference.
