In 2013, B2B content marketers increased their use of tactics from 8 to 12, with significant growth in research, videos, mobile, and virtual conferences, though they remain uncertain about their effectiveness. Social media usage rose to 87%, with LinkedIn becoming the leading platform, while average spending on content marketing grew from 26% to 33% of marketing budgets. A key challenge for marketers this year is producing enough content, contrasting with the previous year's focus on creating engaging content.
