The world of social media marketing is changing all the time, so no matter how well you think you’re doing in that area, don’t start getting complacent. New forecasts from eMarketer project which social networks will be the most popular business marketing tools in 2017. Here’s what’s hot (and not-so-hot):

Instagram will overtake Twitter as a social media marketing channel. Nearly three-fourths (74 percent) of businesses will use Instagram for marketing, up from 53 percent currently.
Twitter will hold steady, with 66.2 percent of marketers using it in 2017 compared to 66.1 percent this year.
Facebook has already reached saturation, with 85.3 percent of marketers currently using it and 85.8 percent projected to use it next year.
YouTube, too, has pretty much plateaued: 48.2 percent of businesses will market with YouTube next year, up from 45.6 percent this year.
