What is Share of Shelf (SOS) & Why It Matters for Retail Brands

Ever wondered why some brands stand out immediately when you walk into a store, while others fade into the background? That visibility often comes down to one metric: Share of Shelf (SOS).

Let’s break down what it really means, how it’s calculated, and why retail brands should treat it as a frontline KPI.

What is Share of Shelf?

Share of Shelf (SOS) refers to the percentage of shelf space a brand or product occupies within a specific category or section in a store. It’s not just a number — it’s a visibility metric that reflects how much physical presence a brand has at the exact moment a shopper is deciding what to buy.

Example: If a juice brand occupies 2 out of 10 facings in the beverages section, its SOS is 20%.

Why Share of Shelf Is a Big Deal for Retail Brands

In a cluttered retail environment, products compete for attention before they compete for wallets. The more space you command, the higher your chance of being seen, picked, and purchased.

Here’s what a strong SOS can unlock:

• Higher brand recall and awareness
• Better conversion at the point of sale
• Increased negotiation power with retailers
• Stronger campaign execution through visual impact

How to Calculate Share of Shelf

SOS is typically calculated using:

Linear SOS (%) = (Shelf length occupied by the brand / Total shelf length in category) x 100

Some teams also track:

• SKU count vs competitors
• Vertical visibility (eye-level placement)
• Depth and facings

Use Cases: How Retail Brands Improve Their Share of Shelf
