The marketplace front door is moving
When a buyer asks ChatGPT for a thoughtful gift, the marketplace ranking page is no longer the first surface they see. Amazon's Rufus is doing the same thing inside the Amazon app; Walmart's Sparky and Gemini-powered checkout are doing it on Walmart. Sellers who know their true per-SKU margin can defend pricing when an agent surfaces three competitors side by side. Sellers who do not will price by gut and lose.
Structured attributes are now ranking signals
Conversational search ranks on what the listing actually says, not just on the title. Material, dimensions, occasion, recipient, color family and care instructions become first-class ranking inputs. Sellers should pull a full attribute-completeness audit per ASIN through Nova's custom analytics and prioritize gaps on top SKUs by winners and losers.
Agent-referral traffic needs its own channel
Agent-mediated buyers convert and return differently from organic and paid. Tag every referral that arrives from ChatGPT, Perplexity, Comet or Gemini into a separate channel in your reporting and reconcile margin per channel. Nova's Data API ships hourly Amazon data into your BI layer so this segmentation lives next to organic, sponsored and DSP attribution.
Etsy is the canary, not the story
Etsy is small relative to Amazon, but it is a fast-moving marketplace with a willingness to ship. The pattern Etsy is validating, conversational marketplace shopping inside a third-party LLM, is the same pattern Amazon and Walmart will run at scale. Sellers concentrated on Amazon should watch the same playbook through the lens of our Amazon and Perplexity Comet coverage and the Amazon and OpenAI partnership.
