Recommendation Placement Snapshot

Questions This Section Answers

• Why does top-three placement differ from overall recommendation coverage?
• Which platform ranks first most often despite lower overall coverage?

Where a brand appears in the recommendation order matters for buyer attention. WooCommerce leads on coverage but ranks first far less often than Shopify POS, which continues to hold a disproportionate share of first-position recommendations.

Comparable coverage can still hide very different first-position rates: WooCommerce covers 80.5% of qualified observations but ranks first only 3.6% of the time, while Shopify POS covers 35.9% of observations but ranks first 32.7% of the time, a gap that coverage alone does not reveal.

Buyer-Intent Distribution

Questions This Section Answers

• What kinds of buyer-intent questions does this eCommerce benchmark actually capture?

All qualified observations in both months fell into the Brand Recommendation class, meaning the public series captures discovery and consideration questions where buyers seek brand recommendations.

The current public series measures Brand Recommendation discovery and does not yet contain qualified observations in the Pricing & Value or Multi-Brand Comparison classes.

Historical Measurement Record

• How has the eCommerce Websites coverage leader changed across the four monthly measurements?
• Which month produced the largest single-brand coverage movement?

This is an evergreen benchmark URL. New measurements are added to the same report.

Evidence and Source Layer

Questions This Section Answers

• What source and citation data does the benchmark retain for each AI observation?
• How should source presence be interpreted when evaluating AI recommendations?

The benchmark is built from prompt-level observations that retain the query, AI/search surface, answer, brand outcome, recommendation placement, sentiment, and, where exposed, citations or attributable evidence sources. Source presence is evidence about the information environment. It is not automatically proof that the source caused the recommendation.

Scope Boundaries

This public benchmark does not measure market share, attributable sales, every possible AI response, organic-search ranking, social mention volume, private or sponsored channels, or causality from a metric movement alone. It records what AI surfaces recommend across the tracked surfaces and prompt set, and it treats each metric as a distinct signal rather than a proxy for another.

Top 10 Cited Domains

Questions This Section Answers

• Which domains are cited most often across AI platform responses for eCommerce Websites?
• How concentrated are citations among the top domains, and which source types appear?

Across all AI platform responses in October 2026, the benchmark observed 6,162 citations spanning 1,276 unique domains.

Citations are broadly distributed across the top 10, with no single domain exceeding an 11% share, and the remaining 1,266 domains absorb the balance. Three tracked brands' own domains appear in the top 10: shopify.com, bigcommerce.com, and wix.com. Video and community platforms, official brand sites, technology and productivity media, and general business press all appear, with no one source type dominating.
