The growth in popularity of hashtags
Hashtags describing a topic or campaign offer prefaced by '#' are now a common feature across most social media platforms. So no longer just Twitter, but including Facebook, Pinterest, Instagram and Google+... If used correctly, then they can improve reach and social sharing of content for brand awareness and lead generation.
There are many Twitter tools to find trending hashtags and to ensure you use relevant hashtags.
Offerpop's Infographic provides a timeline history for the use of the #Hashtag from its initial use on Twitter to later adoption on Facebook and Google+. Greater engagement with hashtags is suggested by research referenced in the infographic which shows that 'Tweets that contain hashtags are 55% more likely to be retweeted than those that do not, and more than 70 percent of people use hashtags'. We don't see that type of impact or usage, but thought this was an interesting infographic which would perhaps prompt readers to think how they use hashtags compared to their competitors.
