The latest holiday forecast should not push retailers into a simple answer: spend more in Q4. It should push them to ask whether their ecommerce operation is ready for shoppers who compare harder, use digital tools earlier and expect promotions to make economic sense.
Retail Dive reported on September 10, 2026 that Deloitte expects holiday ecommerce to grow faster than total retail sales for the November 2026 to January 2027 season. Deloitte forecasts total holiday retail sales growth of 4% to 4.8%, while ecommerce is forecast to grow 7.5% to 8.4% to roughly $316.1 billion to $318.9 billion.
What changed in the shopper journey
The forecast is not only about channel mix. It reflects shoppers using digital tools to research, compare and complete purchases across categories. Retail Dive also cited Bain research saying 24% of holiday shoppers plan to begin discovery with AI tools such as ChatGPT, Google Gemini or Claude.
That does not mean AI assistants will close every sale. It means more product decisions may begin outside the retailer’s site, search campaign or email flow. If product data is incomplete, promotions are confusing or delivery promises are hard to compare, the retailer may lose before the shopper reaches the cart.
A readiness model for Q4
Product data readiness. Titles, attributes, sizing, availability, reviews, images, delivery dates and return rules need to be consistent across feed, site, marketplace and content pages.
Value signal readiness. Value-seeking does not only mean discounting. Show bundle logic, durability, warranty, loyalty value, shipping thresholds and gift suitability clearly.
Promotion governance. If every channel carries a different offer, comparison shoppers and AI tools may surface the wrong promise. Decide which offers are authoritative and where exclusions are explained.
Margin protection. Holiday growth is useful only if promotions, paid media, returns and fulfillment costs do not erase profit. Build margin guardrails by category before scaling traffic.
Where media fits
Paid media still matters, but it should point to pages that can survive comparison. Search and shopping campaigns need clean feeds. Paid social needs giftable reasons to click. Email and CRM need segments based on intent, margin and timing. Retail media needs proof that promoted products are in stock and competitively presented.
The weakest plan is to drive more traffic to unclear product pages and hope AI-assisted shoppers behave like last year’s visitors. The stronger plan is to prepare the evidence that comparison tools and humans both need.
The operating decision
Before holiday budgets lock, run a category-by-category review. Which products can win on value without destroying margin? Which pages answer comparison questions? Which promotions should be visible to assistants, search engines and customers? Which delivery promises are safe close to peak dates?
Holiday ecommerce growth will reward retailers that make buying easier to validate. The new race is not only for traffic. It is for trust at the moment of comparison.
