Revenue is the most visible number in any ecommerce business. It is also one of the least useful for understanding whether the business is actually healthy.
A store can grow revenue while simultaneously eroding margin, becoming more dependent on paid traffic, and losing the ability to retain customers. Revenue going up while these three things are happening is not growth. It is a deteriorating business with a flattering top line.
When I open a new client's dashboard for the first time, I look at three numbers before I look at revenue. These three metrics tell me more about the health of the business — and what to do next — than any sales figure.
What it is: The percentage of visitors to your store or listing who complete a purchase.
What good looks like: Between 1.5% and 3.5% for most ecommerce categories in Southeast Asia, depending on product type and platform.
What concerns me: Anything below 1%. A conversion rate below 1% means that for every 100 people who visit your store or click your listing, fewer than one of them buys. That is not a traffic problem. That is a product page, pricing, trust or checkout problem — and spending more on ads to drive more traffic to a store converting at 0.8% is an expensive way to stay stuck.
Why it matters more than revenue: Revenue can grow even with a low conversion rate if you are spending heavily on traffic. The moment you reduce ad spend, revenue collapses. Conversion rate above 2% on your key products means the store is working independently of how much you spend on advertising.
What to do when it is low: Open your GA4 funnel exploration and find the specific stage where buyers drop off. Product page to add to cart, add to cart to checkout, or checkout to purchase — each drop-off point has a different cause and a different fix. Do not guess. The data will show you exactly where to look.
What it is: The percentage of your total traffic that comes from organic sources — Google search, AI tools like ChatGPT, direct visits, and referrals — rather than paid advertising.
What good looks like: Organic traffic should account for at least 30% of total traffic for a store that has been live for more than 12 months.
What concerns me: Organic traffic below 30% of total traffic. When paid channels — platform ads, social ads, influencer campaigns — account for more than 70% of all traffic, the business is entirely dependent on continued ad spend to generate any sales at all. The moment budgets are cut, traffic disappears.
Why it matters more than revenue: Organic traffic is the only traffic that compounds over time. Every article you publish that ranks on Google or gets cited by ChatGPT generates traffic indefinitely without additional cost. Paid traffic stops the moment you stop paying. A business with strong organic traffic is resilient. A business with only paid traffic is fragile.
What to do when it is low: Start building organic visibility immediately — both for Google through structured content and FAQ schema, and for AI tools like ChatGPT through AEO strategy. This takes 6 to 12 months to show meaningful results, which is exactly why most businesses are reluctant to start. Start anyway.

What it is: The percentage of your customers who have made more than one purchase from your store.
What good looks like: Above 20% for most fashion and lifestyle categories. Above 30% for consumables, supplements, and regularly repurchased products.
What concerns me: Below 10%. A returning customer rate below 10% means that for every 100 customers you acquire, fewer than 10 come back. You are on a treadmill of constantly finding new customers at increasing acquisition cost, with almost no benefit from the relationships you have already built.
Why it matters more than revenue: Returning customers cost significantly less to convert than new ones. They already trust you. They do not need to be convinced by a review score or a listing image. They have experienced your product and your service. A business with a 30% returning customer rate is generating a meaningful portion of its revenue from people who cost almost nothing to convert.
What to do when it is low: The most common cause of a low returning customer rate is the absence of post-purchase communication. No email after delivery. No review request. No new arrival notification. No loyalty incentive. Set up a simple post-purchase email sequence: a delivery follow-up at three days, a review request at seven days, and a new arrival or recommendation email at 30 days. For Shopify stores, this runs automatically through Klaviyo or Shopify Email. For marketplace stores, use the platform chat and review request tools.
Of the three, returning customer rate is the one that catches most founders off guard. They focus intensely on acquiring new customers and almost never measure how many of those customers come back.
When I show a founder that 93% of their customers never return, the usual response is disbelief followed by immediate recognition of why: they have never sent a single post-purchase email. They have no loyalty program. They have never told a past customer about a new product.
Fixing the returning customer rate costs almost nothing compared to the cost of acquiring the same volume through paid channels. It is consistently the highest-return change available to any store that is not already doing it.
Revenue tells you what happened. These three metrics tell you why — and what to do next.
