Infographic: What Marketers Talked About Most in 2014

CRM, analytics and lots of mobile

According to data from Salesforce, 86 percent of top marketers say building a holistic marketing approach is a top priority, but only 29 percent of companies say they actually have the structure in place.

The data point is one of several findings compiled from the ad-tech vendor this year. In terms of tactics: email, social media and mobile continue to grow for brands.

But despite the growing interest in mobile marketing, only 51 percent of survey participants said they expect mobile to have a return on investment. Thirty percent of marketers use location-based technology, and 47 percent have an app.

Meanwhile, 68 percent of marketers polled said email is a key piece of their strategies. But a sizable chunk of marketers aren't just blasting out emails—64 percent of respondents said their companies send out 1 million or fewer emails per year.

So, what keeps CMOs up at night? Per Salesforce's findings, that includes data and analytics; new customer service roles; and lining up a company's internal functions.
