This plugin will completely remove the mandatory 'Tag Base' from your tag permalinks (e.g. `/tag/my-tag/` to `/my-tag/`).
Use this plugin if you want to get rid of WordPress' "tag" base completely. The normal behaviour of WordPress is to add '/tag' to your tag permalinks if you leave "Tag base" blank in the Permalink settings. So your tag links look like
myblog.com/tag/my-tag/. With this plugin your tag links will look like
myblog.com/my-tag/ in case of sub categories).
Why do this? Well, shorter URLs mean betting indexing and bottom line is: it's good for SEO. Having the meaningless "tag" in your permalinks will dilute their keyword relevance. Keep your tag permalinks tight with this plugin.
