SEO for Taxonomy Views

I noticed that for one of my clients website the search engine output had really poor page descriptions for all of the taxonomy / category views. The Drupal default taxonomy output only has the name of the taxonomy term, but no description by default.

I always end up searching for the wrong thing when looking for a solution to my problem - I was looking for a module or a hack that would allow me to add descriptions to each taxonomy page, but I just discovered that I can theme taxonomy views! Yes you can create a template for the output of taxonomy - in fact you can create templates for all types of content output:

Finish this later.
