Statistics on the efficacy of inbound marketing
Statistics provided not only by HubSpot but other marketing solution providers and research organisations as well, suggest that inbound - if done well - is significantly more cost-effective than outbound, or at least outbound alone. Selected stats from Impact Branding & Design, SmartBug Media, as well as some of my own. Categorized by (1) Inbound versus outbound, (2) Buyer preferences and behavior, (3) The impact of content, and (4) Marketing automation.
