What is this Tag feature you may ask? A pretty nifty little invention for sure. Tagging is a way to lable content on your blog or any website. It is great serach engine bait, similar and possibly better than meta-tags for your website. Some WordPress plugins allow you to use your regular tags as meta tags (All In One SEO plug-in).

Will it help your blog gain popularity? Not as much as writing great content that everyone wants to get their hands on. But, if used to tag great content, then yes. So start tagging my friend.
