Believe that many people do not know the specific TAG label is what, on the site and will bring what kind of influence, first I sites use CMS inside had to add TAG tags function, but since the application is not very full, sometimes it is empty, sometimes directly write key, the a healthy site may not have any negative impact, then the TAG label what effect?

TAG tags and keywords have the same important position, I think the key is for search engines to see, while the TAG tags for the user is browsing, is direct. Many websites will the TAG tags are displayed in the foreground, for example one of my website ..........com, this is one of the cleaner product website, its TAG label is displayed in each article under the heading, although less marked, but the user can find the TAG tags of all articles. So I think, TAG tags is to their own articles were classified, and then some related articles placed in this category, is convenient for users to browse. For example, your article is titled " the diesel polite filter maintenance of common sense", the TAG label can be" air" or" filter of a diesel engine".
