Multi-Channel AI Commerce

Multi-channel AI commerce is the practice of selling through several AI shopping assistants at the same time. Traditional multi-channel meant Amazon, your own site and social platforms. The AI version means ChatGPT, Google AI Mode, Perplexity, Microsoft Copilot and the platforms that follow (see our note on Meta joining the AI shopping race).

Each channel has its own route in:

• Feed: Google Merchant Center for AI Mode and AI Overviews, the OpenAI product feed for ChatGPT, Perplexity's merchant program for Perplexity
• Purchase path: ChatGPT sends shoppers to the merchant, Google uses UCP, Perplexity uses PayPal where merchants are enrolled
• Onboarding: separate enrolment for each, much of it now handled by Shopify and the other commerce platforms

What they share matters more than what differs: every one of them reads the same product information and recommends from it.

No single assistant covers all shoppers or all moments:

ChatGPT is the largest conversational audience and leans toward personal-shopper style questions.

Perplexity attracts research-driven shoppers who want comparisons with cited sources before a considered purchase.

Google AI Mode sits inside the search engine most shoppers already use, at the moment of search intent, with Google's product index behind it.

Microsoft Copilot reaches people inside Windows and Microsoft 365, including business buyers.

A retailer visible only in ChatGPT misses the researchers on Perplexity and the search audience on Google. The channels also behave differently: the same product can be recommended on one and absent on another, which is why visibility is measured per assistant.

The protocol side has become lighter. Shopify enrols merchants for ChatGPT and built UCP with Google, and other platforms are following. Payment trust arrives through your processor. For most retailers there is little to integrate.

The product information side is where the work is. Each channel reads your attributes, descriptions and Q&A, and each has slightly different emphasis: conversational and use-case led for ChatGPT, specification-rich for Perplexity, attribute-complete and schema-aligned for Google. The practical answer is one source of product truth, complete enough that every feed drawn from it carries what that channel needs, fixed at the source rather than channel by channel.

That is how Paz runs it. A Paz expert finds the product information gaps behind each channel's misses, corrects supported store or Merchant Center fields and hands PIM source corrections to your PIM owner, our experts publish within agreed guidelines, and the platform tracks appearances in each assistant over time.
