Has anyone used or currently use XenTag, and had significant SEO benefits? I currently have it installed on my site, and I'm not sure how much of an impact it is having.
In the past and based in my experiene (vBulletin and a lot of tags) only put noise in the google indexed data, related to the bad quality of the tags.
But if you have a good tags with good structure, the tags improve your indexed data.
