I'm working on SEO for my WordPress page, and I'm having second thoughts about having my tag archive indexed. I'm not using categories at all, so I've set robots to
noindex, follow for category overviews, making tags the main taxonomy.
Part of me says that having tag archives indexed is useful because those pages are full of content around one specific keywords, and they also link to more pages concerning those keywords. Also, the posts are truncated with a 'read more' link, so there's not going to be a problem with duplicate content.
On the other hand, these pages might dilute the pagerank for my actual posts. What is the use of people finding my tag archive pages if they could also find actual articles? Wouldn't it be better to just follow the links in my tag archives but not have those pages indexed?
Should I index them or just let google follow the links?
