The difference between Tags, Hashtags and Categories.​

The differences between tags, hashtags and categories aren’t always very clear.

According to the dictionary, a Hashtag is:
(on social-networking websites) A word or phrase preceded by a hashmark (#), used within a message to identify a keyword or topic of interest and facilitate a search for it. 

Categories (on blogs and websites) are used to sort and group content into different sections. As categories are broad topics such as for example “General SEO”, “Content Marketing”, or “Books”, they are supposed to identify what your blog is about. Therefore, categories are supposed to give more structure, and help users to find the kind of content they are interested in.

Tags are far more specific and detailed than categories, such as a specific movie genre, artist, marketing technique, and so on. Basically, tags are labels attached to your blog post.

To summarize, a hashtag is a tag with a hashmark that is used within social networking websites such as Twitter. Tags and categories, on the other hand, are used for blogging purposes. While categories are supposed to give structure to the site, tags are very specific for each blog content and more unique.

Hashtag results are classified according to different social media platforms: Twitter, Facebook, Instagram and etc.


Is there an expiry date to tags?

​There are no expiry dates to tags. In fact, in terms of content marketing, tags precedes hashtags in the sense that it covers the broad topic of the information. Tags prove to be helpful in the long run, bringing in inbound leads. Hashtags on the other hand, works better on trending events or current issues/topics (which has the potential to die down after a period of time). An example of a tag and a hashtag for this wikipedia extracted text will be as follows: 

“Held annually in Munich,Bavaria, Germany, it is a 16-day folk festival running from mid or late September to the first weekend in October, with more than 6 million people from around the world attending the event every year. The Oktoberfest is an important part of Bavarian culture, having been held since 1810. Other cities across the world also hold Oktoberfest celebrations, modeled after the original Munich event. This year, Oktoberfest will be held in …”
