Tags are one of the most common terms associated with blogging nowadays. In fact, tags have found their way outside blogging and are now an integral part of content sharing all across the internet -- you tag your photos on Facebook, sort tweets on the basis of hash-tags, and so on. Plus, looking at an article’s tags easily lets you understand what the article must be about. As a result, proper tagging is not only beneficial, but also crucial. Unlike categories, tags retain a similar structure across all blogging platforms (well, almost). For instance, WordPress lets you keep one post under multiple categories, but Dotclear allows you to include one post under one category only. However, when it comes to tags, you can have an almost free way in deciding which ones to use with which article. Owing to such liberal usage, tags are often misunderstood. Some people claim tags are the Godfather of SEO ranking, whereas others consider tags to be a bogus burden in terms of SEO. So, which version is true? In this article, we shall take a detailed look at tags. We will learn what exactly tags and their benefits are, what their role is and how we can utilize them to the fullest.
