E-commerce teams are entering 2026 with many changes. AI search continues to grow, Meta and Google keep shifting tracking behavior, and platform-reported numbers still rarely match what stores see in their backend. With so many variables changing, the brands that win in 2026 will be the ones that understand what is truly driving revenue.
Below are some guidelines for setting your marketing up for success in 2026.
1. Use Multi-Touch Attribution
Top-of-funnel and middle-of-funnel campaigns matter just as much as bottom-of-funnel campaigns. Multi-touch attribution finally makes these contributions visible (unlike the last-click attribution models used by the ad platforms).
Multi-touch attribution in ThoughtMetric assigns credit across every touchpoint and even includes data from the post-purchase survey responses.
With multi-touch in place, you can see:
- How TOF and MOF campaigns influence revenue
- Which channels create early demand
If your goal in 2026 is efficient, predictable growth, multi-touch is the foundation.
2. Tie Revenue to Every Ad, Ad Set, Campaign, and Channel
In 2026, channel-level reporting is not enough. Marketing teams need to trace revenue with precision and understand what is working at every level of the account.
You should be able to see revenue tied directly to:
- Each channel
- Each campaign
- Each ad set or audience segment
- Each individual ad
This lets you answer the questions that drive smart budgeting:
- Which creatives are actually converting?
- Which audiences produce return?
- Which campaigns deserve more investment?
- Which experiments should stop early?
When you can drill from channel → campaign → ad set → ad in ThoughtMetric and see revenue tied to every step, decisions become clearer, and scaling becomes far less risky.
3. Use Product-Level Attribution To Guide Your Growth Strategy
2026 will be a product-driven year for many brands, especially as AI search and recommendation engines influence what shoppers see first.
- Which products drive the most revenue
- Which channels convert best for each item
- And more!
This helps you shape your creative strategy, decide which products to feature in ads, and understand where channel-product fit is strongest. It also helps teams avoid overspending on products that do not convert well across channels.
4. Prepare for a Shift From Organic Search to AI Search
AI search is still early, but it is already reshaping how people discover products. Our data shows that AI search currently accounts for only 0.2% of revenue. That number is small today, but we expect it to grow throughout 2026 as shoppers get more comfortable relying on AI-driven recommendations.
This shift will not replace organic search overnight, but it will gradually influence how customers find products, compare options, and enter the funnel. Brands should begin preparing now by:
- Staying up to date on AEO best practices
- Monitoring how AI platforms surface their products
- Understanding how AI search traffic behaves once it reaches the site
ThoughtMetric lets you track AI search activity, see which product pages are clicked, and understand how those clicks convert alongside your other marketing channels.
The Bottom Line
Marketing success in 2026 will come from clarity. With Multi-touch attribution, revenue tied to every level of your ad account, product-level attribution, and monitoring the shift to AI search, you build a measurement system that shows you what is working.

FAQs
How is multi-touch attribution different from last click?
Last click gives all credit to the final interaction before purchase. Multi-touch distributes credit across every step in the journey so you can see how top, mid, and bottom-funnel channels actually work together.
Is AI search really important for e-commerce brands yet?
It is early, but it is growing. Our data across 200 e-commerce brands shows AI search accounts for 0.2% of revenue today. We expect that number to rise in 2026 as shoppers rely more on AI-driven recommendations.
Can I measure AI search performance in ThoughtMetric?
Yes. You can see which products AI platforms recommend, how shoppers enter your site from AI search, and how those sessions convert compared to other channels.
What is the biggest mistake teams make with attribution?
Relying only on platform-reported numbers. These are often inflated or incomplete. Connecting your data to a verified source of truth helps you make decisions you can trust.
What is the first step to improving attribution in 2026?
Start with multi-touch attribution and align the entire team around one measurement model. Then layer in product-level reporting and AI search tracking to get a complete view of performance.
