The study analyzed data from 4,000 HubSpot customers to determine relationships between inbound marketing activities and traffic/leads. It found that businesses that blogged more frequently (16-20 times/month or more), had more web pages (401-1,000 pages) and landing pages (31-40 pages or more), and had larger social media followings (301-1,000 Twitter/Facebook followers or more) saw significantly more website traffic (2-22 times more) and generated more leads (3-12 times more) than businesses with less activity in those areas. The results provide insights into best practices for content creation and social media use to optimize lead generation.
