Exposing Tags: How It Works and Why You Should Do It
Tagging is an important part of the editorial workflow for two main reasons: SEO organization and an intuitive taxonomy for your content.
In terms of your site's architecture, tags create structure without requiring explicit sections. This can be helpful if you want to add some organization to your site without making official sections. See this article for more information on using tags to create structure.
But most importantly, tagging is vital because of its role in SEO. When you expose tags in a post, it tells search engine crawlers what's on the page. The crawlers then see your page as useful and relevant, and reward you by improving your rank for targeted SEO search phrases. Tags add more context and expose more content to be crawled. This was effective for our founder and CEO Andrea Breanna when she was CTO of The Huffington Post.
