To those less familiar, hashtags may be defined as labels for content. Hashtags are commonly used to categorize posts or add a narrative to your updates. Marketers have of course found some innovative ways to use hashtags as a mean to drive conversation, canvass the public support, and grab attention to their brands.
Your social media activity revolves around reading other people’s updates on Facebook and Instagram, so the reason to tag your posts. Hashtags will change the way you use Twitter and other social media channels.
Unsurprisingly for people over the age of 30, hashtags are still a novelty.
The pop-culture adoption of hashtags helped push hashtags (initially used widely on Twitter) into other social networks. Instagram adopted hashtags during 2011, Flickr added hashtags during 2013 and Facebook finally broke and adopted hashtags during mid-2013.
Hashtags are today being adopted as a social media marketing tool. Surveys reveal that the world’s top brands have adopted the use of hashtags in their SMM activities almost completely.
Using hashtags in SMM (Social Media Marketing) activities have proven to lead to more engagements. When compared to Tweets without a hashtag, tweets with hashtags showed 12 percent more engagement. Tweets that included a link and a hashtag, showed the highest engagement rate of any other type of tweet.
Since most social media channels adopted hashtags as an identifier, brands can now run social media campaigns with one common identifier, virtually making hashtags the global connector of the social web.
Hashtags have become increasingly important in social media marketing campaigns. Hashtags particularly enable content marketers to attract the attention of their target audience. Hashtags identify social media conversations that are relevant to their business.
When used rightly, hashtags can be terrific tools that drive brand recognition, enhance reach, develop community, create buzz, and positively build customer loyalty.
Anyone sharing content can add hashtags to their messages and these hashtags will help people instantly find information on that same topic.
Twitter, Pinterest, Instagram and Google Plus are platforms that support hashtags. Facebook use of hashtag has not really caught on.
Pinterest uses the same hashtag approach as other platforms. Using hashtags on Instagram can help optimize your reach and help develop a network of brand followers. Using hashtags is an excellent method to get your Google+ posts noticed in search engine results.
Make sure not to use more than two hashtags per post. Over-usage of hashtags will defeat the purpose.
