SEO was the most time-consuming—and most used—inbound marketing tactic for online marketers worldwide: 23.9% spent more than half their time on SEO. Just 7.8% invested similar time in social media marketing and 6.3% in content marketing.
Still, many found time each day to devote to all three. More than half practiced SEO daily. Near half managed their social media programs every day, and 23.7% performed content marketing daily. Of the remaining marketers, roughly 20% managed one or more of those three tactics at least two to four times per week. Read the rest at eMarketer.
