With AI and BI dominating the industry for ecommerce businesses, marketing is no longer just about the positive aspects of running campaigns. It\u2019s reshaping the entire concept of putting yourself out there and understanding what those campaigns actually deliver. In the most real terms, with multiple channels, tools, and touchpoints, ecommerce businesses oftentimes feel that they are struggling to measure true marketing performance in a unified way.<\/span><\/p>\n

To be fair, that\u2019s true considering that a lot of businesses are still choosing to stay traditional. This ultimately reflects in their long-term reports, as their data and information are not in front of them in real-time.<\/span><\/p>\n

However, when they want to focus on the marketing aspect and how it has been building their brand, they must go ahead with the <\/span>Marketing Efficiency Ratio<\/span> (MER). Instead of looking at isolated metrics that are based on manual data, delayed market understanding, and not-so-unified data reporting, MER gives you a complete picture of how efficiently your marketing spend translates into revenue.\u00a0<\/span><\/p>\n

Now the real question that comes to mind that makes a difference in terms of efficacy of marketing, lies here in this bifurcation.

The concept is more like a profit-and-loss situation. Unlike channel-specific metrics, the <\/span>sales and marketing efficiency ratio<\/span><\/i> considers your entire marketing effort. That makes it especially useful for businesses running campaigns across multiple platforms where attribution isn\u2019t always clear.<\/span><\/p>\n

Why MER Matters for Ecommerce Businesses?<\/b><\/h2>\n
