Ecommerce shops benefit most from AI when it helps make better decisions to improve productivity and profitability.
“In the early days of AI adoption, many retailers focused on isolated pilots — chatbots here, demand forecasting there. What distinguishes today’s leaders is not experimentation, but integration. AI is increasingly deployed as a set of interconnected levers that reinforce one another economically,” according to the authors of a June 2026 McKinsey & Company report, “Europe’s new ecommerce agenda: How AI is resetting growth and competition.”
The interconnected levers McKinsey describes form a pattern for ecommerce flywheels.
AI Flywheel
A flywheel in this context is a system that gains momentum as each part improves the next. With each cycle, the flywheel spins more easily and accelerates process improvement.
For example:
- AI-powered personalization increases customer engagement.
- More engagement creates better demand signals.
- Better demand signals improve pricing and inventory decisions.
- Superior pricing and inventory create more engagement and more data.
This is different from asking AI to complete a single task.
A merchant using AI to write a product description has saved time. A merchant using AI to analyze customer questions, increase conversions, and inform future merchandising decisions is building a flywheel.
4 Levers
In its report, McKinsey argues that four “value levers” stand out when it comes to building an AI ecommerce flywheel.
- Growth. AI can improve product discovery, recommendations, email segmentation, ad creative, and product-page content. The goal is to help the right shopper find the proper product.
- Productivity. AI can reduce repetitive work in customer service, content, merchandising, reporting, and administration, freeing employees to focus on high-value tasks.
- Value-chain efficiency. AI can help connect demand, inventory, fulfillment, and returns. A merchant can operate much more effectively by understanding what shoppers want, what is in stock, what is likely to sell, and what can be delivered.
- Profitability. AI can enable better pricing, promotion, bundling, markdown, and assortment decisions. It can help merchants see profitable revenue, unnecessary discounts, and problems that erode margin.
These levers overlap, and that is the point. AI becomes more valuable when it connects decisions, rather than automating isolated tasks.
Beyond Enterprise
The McKinsey version of the AI flywheel can seem enterprise-level.
It assumes well-organized data, integrated systems, robust analytics, and sufficient traffic to generate useful signals quickly. Many small and mid-sized merchants do not have those advantages.
But small shops can build a loop around a recurring problem.
Small stores certainly have useful data, albeit scattered across an ecommerce platform, email inbox, spreadsheets, inventory reports, reviews, and analytics accounts.
That is enough to begin.
Start with customer feedback and questions. Use AI to analyze shopper emails, contact form submissions, chats, reviews, social media comments, and return reasons. Have the AI look for recurring objections such as size confusion, unclear compatibility, shipping concerns, missing instructions, or doubts about quality.
Then use those findings to improve product pages, FAQs, comparison tables, buying guides, product photos, and post-purchase emails. Test the changes and track conversions, returns, support volume, and revenue per visitor.
This is a small flywheel. Customer feedback improves product content. Better product content reduces friction. Less friction improves conversion and lowers avoidable service work. The new results create better data for the next round of improvements.
The loop uses AI to understand a recurring need (higher profit), improve the process, measure the outcome, and feed the learning back into the business.
Connected Decisions
The AI advantage for ecommerce SMBs is not access to the most advanced model.
The advantage is managerial. It comes from applying AI to inform the business, measure outcomes, and apply the lessons again.
Thus AI can connect previously separate decisions, linking customer service with product content, site search with merchandising, inventory with promotions, and margin with marketing.
The result is a flywheel.
