What's the best segmentation strategy for a brand with a wide range of SKUs?

The best segmentation strategy for a wide SKU range isn't a complex segmentation strategy at all. It's a SKU rationalization project. Your focus shouldn't be on managing the complexity, it should be on radically reducing it.

The common wisdom is to embrace a large product catalog. It suggests that more choice leads to more sales, so the job is to build sophisticated audience segments for every product category. This approach involves creating unique content and ad campaigns for dozens, if not hundreds, of SKUs. We tell ourselves this is what mature brands do: they cater to every niche and use complex marketing automation to guide customers to the perfect, obscure product. It feels like progress, but it’s often a trap.

The problem is, this approach spreads your resources dangerously thin. As Blake Hutchison pointed out on Ecommerce Coffee Break, it's common to see a few SKUs driving 80% of the revenue, while the other 50 SKUs just sit there. This isn't just a missed opportunity, it creates massive operational drag. On the 2X eCommerce Podcast, Kunle Campbell noted that too many products dilute your brand and create operational inefficiencies. You end up with shallow inventory across the board. The Hammersley Brothers are direct about this, stating that stock depth beats endless product range. When you inevitably go out of stock on a core item, your conversion rates and ROAS can tank, and you can't make up the difference by pushing weaker products.

Jared Mehr made a similar point on eCommerce Evolution when discussing Pura Vida's wholesale strategy. Even for a brand that big, the key was to narrow a 50 SKU line down to the top 10 or 20 to present a clear, concise strategy. The goal is to focus on what Emanuel Rose on Firing The Man calls the 80% using the Pareto's principle, not to give equal attention to the underperforming 20%.

So, what should you do instead? First, use your data to identify the handful of products that generate most of your sales and profit. These are your workhorses. Kunle Campbell advises you to 'trim the fat' by analyzing sales velocity and profit margins to find underperformers. Second, pour your resources into those winners. This means deeper inventory buys, more ad budget, and more creative variations. This strengthens your business core. Finally, for the long tail of underperforming products, you have to make a choice. You can either discontinue them to simplify your entire operation, or as Adii Pienaar suggests, you can bundle a slower-moving SKU with a fast-moving one to clear out overstock without wrecking your margins. The goal isn't better segmentation of a big catalog, it's building a more resilient business on a smaller, more profitable one.
