Organizations that have optimized engagement have outperformed their competitors by 26% in gross margin and 85% in sales growth

Or so says Gallup in their description of world-class companies that utilize Customer Engagement (CE) strategies and measure their CE efforts. Furthermore, Gallup has developed an Engagement ratio that can provide companies with "a macro-level indicator of an organization's health that allows executives to track the proportion of fully engaged to actively disengaged customers".
