The Evolving Buyer’s Journey

In today’s digital age, the buyer’s journey is more complex than ever. It’s no longer a linear path from seeing an ad to making a purchase. Instead, it involves multiple touchpoints across various platforms. A potential customer might first encounter your product through a social media ad, but they might not trust purchasing directly through that platform. This skepticism leads them to search for your product on Google, where they encounter another set of ads or a promotional video.

The Role of Remarketing

The journey doesn’t end there. Remarketing strategies then come into play, presenting the potential customer with different ads across display networks or even in their email. This multifaceted approach often leads them to your website, where they might bookmark a product page, seek out online reviews, and, after careful consideration, return to purchase that bookmark.

The Challenge of Direct Attribution

This convoluted journey presents a significant challenge in determining direct attribution for conversions. In such scenarios, it’s nearly impossible to credit a single touchpoint or campaign for the final conversion. Instead, it’s the cumulative impact of your omni-channel marketing approach that leads to the successful conversion.

Enter MER: The New Metric for ROAS

Given these complexities, the Marketing Efficiency Ratio (MER) emerges as a more holistic and accurate metric to analyze your Return on Ad Spend (ROAS). Unlike traditional metrics that attempt to isolate the impact of individual campaigns, MER considers the overall efficiency of your marketing spend across all channels and touchpoints.

Understanding MER

MER is calculated by dividing the total revenue generated by the total marketing spend. This ratio offers a broad view of the effectiveness of your marketing efforts, encompassing every interaction and touchpoint that contributed to the final conversion.

The Cookie Apocalypse

Adding to the complexity is the impending “Cookie Apocalypse” – a major shift in digital marketing due to evolving privacy regulations and the phasing out of third-party cookies. This change, detailed in the article “The Cookie Apocalypse: Navigating the New Era of Digital Marketing,” signifies a pivotal moment for marketers and business owners.

MER in the Post-Cookie Era

In the post-cookie era, traditional methods of tracking and attribution will become less effective. As we lose the ability to track individual user journeys across the web, MER stands out as a resilient metric that still offers valuable insights into the overall efficiency of marketing spend.


In conclusion, as we navigate these changes and the complexities of modern buyer journeys, MER is poised to become the new ROAS in 2024 and beyond. Its ability to provide a comprehensive view of marketing efficiency makes it an indispensable tool for marketers and business owners looking to maximize their marketing investments in an increasingly fragmented and privacy-focused digital landscape.
