A few days ago, I blocked the tag pages on my music blog from search engines. Why? Each of the tag pages was recording 80+ internal inbound links as opposed to my individual stories that were getting 1-2 inbound links. The tag pages are very dry, so I wanted more SEO traffic to individual stories. Each post on my blog includes streaming music or a music video, so they should generate more repeat and return usage.
I'm already getting direct SEO traffic to my stories now.
