This infographic from Introhive does a nice job in breaking down tactics to channels for business to business (B2B) marketing efforts that drive sales results. I'm not convinced that the advice here should be literally accepted by every B2B organization, but it does supply some great descriptions as to how the channels can benefit your sales efforts.
This resource is meant to help you understand the B2B marketing and sales landscape so you can identify the right strategies and tactics for your organization. After careful analysis and years of experience in B2B marketing, we have looked at the effectiveness of everything from Twitter to cold calls.
