Also known as the number or pound sign, the hash sign quickly becomes a hashtag when followed by a word or phrase. A hashtag is used to help your post become more recognizable within relevant categories. You choose the hashtag specific to where you want your post to be discovered.
Studies show that anywhere between 3-9 hashtags are more than enough. Remember, you want your post to be discovered, not lost!
Use general hashtags such as #restaurant. By doing this you are now competing with 42.5 million posts. The chances that your relevant audience even follows this hashtag are minuscule.
Use more specific hashtags like #pittsburghrestaurants. By doing this you have now narrowed your reach to 19.3 thousand people, which is much more realistic, not to mention, the people that follow that hashtag are most likely close to the city.
• Look at your competitors.
• Consider the industry you are in.
This does not necessarily mean to just hashtag the name of your business, but make it something fun that you can relate to your offering. This is something that you can start promoting for the simple purpose of drawing attention to your social media accounts.
