If you are new to Twitter marketing, you may be confused by the strange symbols and references that are used. But there is a simple explanation to this. It all makes sense when you consider that Twitter was initially conceived with SMS in mind. This meant that a character limitation had to be put in place which in turn left very little space to do other functions.
The @ – The “@” symbol is used to draw attention to a user. For example, @Harry Johnson accidentally squirted ketchup all over himself at Disney world today. However, you should note that this is used in a broadcast sense. If you need to talk to Harry privately, just send him a direct message.
The RT – “RT” is used as courtesy to others. Let us say that you saw an interesting post from one of your friends and want to post it to your own followers. But you also want to give credit to the person who originally posted it as well. This is where you use “RT” and the “@” symbol. Using the previous example this would be posted as, RT @Harry Johnson accidentally squirted ketchup all over himself at Disney world today.
The # – The “#” or hash tag is used to draw attention to words and help with filtering. This way, you can have one channel that shows you Tweets that you are really interested in and think are important. Using the previous example this would look like, @Harry Johnson accidentally squirted ketchup all over himself at #Disney world today. So everyone who is following you and is interested in Disney will see this message in their filters.
