It's that time of year again: planning your marketing spend and projecting sales for the upcoming quarters. The challenge, however, is that there's too much conflicting information out there.

Do you focus on a pure content marketing play, go heavy on social, spin up an outbound team, double down on your SEM and marketing automation, or just shotgun it, business as usual?

No wonder a CMO's job security is often in question. There's a lot of pressure to get everything right while constantly seeking the next silver bullet that will drive profits for stakeholders. And every marketing activity can't be directly correlated to driving leads.

But figuring out the most effective methods for generating B2B sales leads should be top of mind for companies looking to connect ROI to their marketing efforts. That will ensure that you're feeding the sales machine, and, as every marketer knows, that means more support for the equally crucial but longer-term marketing activities that are harder to attach to a quarterly goal.

Earlier this year, MarketingProfs ran a series of articles on B2B lead generation. The following infographic should help distill the trends that B2B marketers will be riding to find success in 2014.

The results may surprise you.
