Functional maturity ladder

Discovery is solved. Mandates are not.

Agentic commerce is eleven rungs, not one feature. Most public "AI shopping" launches sit in the first half of this ladder.

  1. L0

    AI readability

    Broad but uneven

    Agent can understand the site and product pages

    SEO/GEO/AEO tooling, crawlers, schema

  2. L1

    Product discovery

    Live

    Agent can ingest or search the catalog

    OpenAI product feeds, Google Merchant Center, Shopify catalog

    Recommendation

    Live

    Agent maps shopper intent to products

    AP2, Stripe agentic payment rails, Visa/Mastercard initiatives

  9. L8

    Identity, account, loyalty

    OAuth/account linking, UCP roadmap, MCP/A2A patterns

  10. L9

    Post-purchase support
