What is Hashtag???

A hashtag or this symbol “#” as it is more commonly known has become an integral part of social media.

A hashtag is a label for content. It helps others who are interested in a certain topic, quickly find content on that same topic.

Hashtags are used mostly on social media sites.  They rocketed to fame on Twitter.  But now you can use hashtags on other social platforms, such as Instagram, Facebook, Pinterest and Google+

Anyone sharing content on a relevant topic can add the hashtag label to their message.  Others searching for that topic, can search for that label to find other messages on that same social media platform.

Hashtags for such situations also provide a way for the public to express their sentiment  — something many of us feel compelled to do in the case of a disaster.  When it comes to natural disasters, a hashtag is like an information lifeline.

How to Hashtag?

• No Spaces Allowed
  A hashtag can be a single word, an abbreviation, an invented combination of letters and numbers, or a phrase.  If it is a phrase, there can be no spaces between words. You can’t have punctuation or symbols in your hashtag. Numbers are OK, but you must also have at least one letter with the numbers — hashtags cannot consist entirely of numbers
• Start With the # Symbol
  To create one, start with a hashtag symbol # and follow it directly with letters and sometimes numbers. The symbol # is called various things, it depends where are you in the world. In the United States and Canada, it is called a number sign or sometimes a pound sign.
• Create Your Own Hashtag 
  Anyone can create a hashtag.  I’ve created numerous hashtags over the years.  You could create one of your own or several if you wish. Usually, you add it to the end of messages.  But you could add it anywhere in the message that makes sense, as long as it’s readable. You are not required to register a hashtag anywhere.
• Make Hashtags Unique
  If you think you’ve invented a hashtag that’s completely new, do a search first on the social platform you intend to use it on.  We find that about 25% of the time, the hashtag we want to use is already being used for some other purpose.
• Make Hashtags Easy to Remember and Understand
  Keep hashtags as short as possible.It’s best if a hashtag is an understandable word, phrase or abbreviation. Hashtags that are long, hard to pronounce or hard to remember, will be hard for people to use, too.
