According to a new study from Simply Measured, 71% of the most recognized brands in the world are now active on Instagram. That number represents an 80% year over year growth rate, and brands’ adoption of the platform rivals Google+ and Instagram. That same study also concluded that as brand activity on Instagram increases, so too do followers, with automobile brands leading the way. It’s easy to see why automotive brands would do well on Instagram; people love sharing photos of cars. But what’s also important to note is the fact that brands with the most engagement actually didn’t use hastags as often as most users or other brands. Believe it or not, hashtagging the world doesn’t give you more reach or impressions.
