When it comes to building an exceptional e-commerce brand, one key factor separates good brands from truly amazing ones: an optimized website. Over years of scaling successful e-commerce brands, I’ve noticed that the best brands don’t just focus on ad spend or traffic—they refine their “best salesperson,” their website, through conversion rate optimization (CRO).

Why CRO Matters

Conversion rate optimization might sound like a buzzword, but it’s a powerful strategy. Every small change, from button colors to checkout flow adjustments, can significantly impact your return on ad spend (ROAS) and drive more sales. Yet, CRO often goes overlooked, with many focusing only on ad spend or traffic.

To show the impact of CRO, I’ve put together a breakdown with real-world formulas and historical data that highlight the results of incremental changes. Here’s an example that shows how these adjustments can transform your brand’s bottom line.

A Practical Example: Daniel’s Hats

Let’s say we have a brand called “Daniel’s Hats” converting at a rate of 1%—meaning only 1% of website visitors make a purchase. Here’s the setup:

• Ad Spend: $20,000 per month
• Visitors: 65,000
• Average Order Value: $45

At this conversion rate, Daniel’s Hats brings in 650 purchases monthly, resulting in $29,000 in sales and a 1.46 ROAS—a low return on investment.

The Power of Small Changes

Now, let’s test an incremental change to the website: adjusting the “Add to Cart” button. By improving this element, we increase the conversion rate to 1.35%. The result? A noticeable improvement in ROAS, nearly doubling without changing any other variables.

This is the magic of CRO. By increasing the conversion rate from 1.35% to 1.65% and then, over several months, to 2.5%, Daniel’s Hats could achieve a 3.66 ROAS—all while keeping ad spend, visitors, and average order value the same. Each incremental change yields significant financial gains and boosts the brand’s overall performance.

Further Improvements: Upsells and Cross-Sells

To take this even further, let’s introduce an upsell feature. By offering customers a 10% discount on orders over $65, we encourage them to increase their order size. With this upsell in place, the ROAS now jumps to 5.28—nearly quadrupling the initial return.

This is the power of refining the user experience and guiding customers to higher-value purchases. Instead of assuming the issue lies with ad performance or email campaigns, sometimes the answer is right on the website.

Why This Matters for Your Brand

CRO is not just about “obvious” math; it’s a clear path to achieving higher returns without significantly increasing costs. By making even slight adjustments, you can maximize each ad dollar and create a lasting impact on your brand’s profitability. Instead of focusing solely on scaling ad spend or making drastic changes, optimizing the conversion rate can deliver far more sustainable growth.

If you haven’t given much attention to CRO, it might be time to start. By optimizing your website, you’re investing in the long-term health of your brand, creating an experience that captures more visitors and encourages larger purchases.

I hope this breakdown has highlighted the importance of CRO and given you some insights on where to focus. Here’s to your brand’s growth—remember, small changes can make a world of difference!
