Using the hashtag, marketers can now aggregate social content and reach social users across Facebook, Twitter, Vine and Instagram with a single campaign.
It has also transformed the way that marketers tie social campaigns into their overall marketing strategy. Through a simple hashtag, brands can now collect, curate and aggregate user-generated content into cohesive social campaigns. And by putting a hashtag as a call-to-action in a traditional advertisement, social campaigns are now taking a central role in how brands execute and follow up on traditional advertising.
