Navigating the Tariffs: How E-commerce Brands Can Protect Profitability?

The latest wave of tariffs is hitting e-commerce brands hard.

With rising Costs of Goods Sold (COGS) and global supply chain pressures, many businesses are seeing their already slim profit margins vanish. For brands that rely on imports, especially from regions like China, this is more than just a bump in the road. The tariffs are hitting harder than ever, and the immediate cash flow disruption is being felt across industries. The cost of doing business has skyrocketed overnight, and e-commerce brands need to act fast.

But this isn’t the time to panic or slash budgets across the board.

Instead, it’s time to get smarter with your marketing spend and adjust your financial models to reflect the new reality. This moment calls for precision.

The Tariff is Real and Expensive

Tariffs are essentially taxes on imported goods. E-commerce and omnichannel retail businesses directly increase COGS. The impact? Let’s look at the numbers.

If your business runs on an 8% EBITDA margin (which is typical), a 15–25% increase in COGS can completely erase profitability.

And that’s exactly what many brands are now facing.

Sourcing costs are up. Consumer demand is shaky. And the pressure to maintain growth while protecting margins is higher than ever.

Marketing Cuts Aren’t the Answer

During downturns, the marketing budget is often the first on the chopping block.

But that move is short-sighted. Studies show that brands that continue to invest in marketing during periods of uncertainty emerge stronger. The key isn’t to spend less—it’s to spend right.

In today’s environment, every dollar must prove its worth. The need for better measurement is more urgent than ever. Relying on platform-reported Return on Ad Spend (ROAS) or outdated attribution models can be dangerous. What might look good on a dashboard might not reflect actual performance, especially when those dashboards fail to distinguish between correlation and causation.

Instead of slashing your marketing budget, you need to make strategic reallocations based on real-time insights. By reallocating your budget to higher-performing channels and campaigns, you can maintain your profitability without cutting essential marketing spend. Smart reallocation, backed by data-driven decisions, is the key to maintaining momentum.

Why Better Measurement Matters More Than Ever

Marketing measurement needs to evolve. Traditional metrics such as impressions, clicks, even ROAS don’t tell you what’s actually driving business outcomes. What you need is clarity. You need to know:

• Which campaigns drive incremental revenue?
• Which channels are underperforming despite high spend?
• Where can you reallocate the budget for better returns?

This is where incrementality testing becomes crucial. Incrementality testing allows you to understand if your ad campaigns are actually causing a lift in sales, or if they’re just appearing to influence the customer journey without any real impact. This approach is especially valuable in an environment where every dollar spent needs to directly contribute to the bottom line.

Unified marketing measurement provides that clarity. It blends multiple methodologies like marketing mix modeling (MMM) and incrementality testing to give you a full picture of performance across every channel. This approach helps you answer the most important question: “What’s really working?”
