The marketing playbook is about to be rewritten. Not because of another social platform or algorithm change, but because your next customer might not be human at all.

The Rise of Agent-to-Agent Commerce

We’re entering an era where AI agents increasingly research, evaluate, and recommend products on behalf of humans. Your customer’s first touchpoint with your brand may no longer be a Google search or a social ad—it might be an AI assistant answering the question: “Find me the best tool for X.”

This shift has a name: A2A (Agent-to-Agent) Marketing—the practice of optimizing your brand for discovery and evaluation by AI agents, not just humans.

How AI Agents “See” Your Brand

When a human evaluates your product, they might:

Skim your homepage for 8 seconds
Watch a demo video
Read reviews on G2 or Capterra
Ask a friend on Slack

When an AI agent evaluates your product, it:

Parses your structured data and metadata
Reads your llms.txt file (if you have one)
Analyzes your documentation and API specs
Cross-references claims against third-party sources
Synthesizes everything into a recommendation

The difference? AI agents don’t get swayed by flashy animations or emotional storytelling. They want clear, structured, verifiable information.

The A2A Marketing Stack

Here’s what forward-thinking brands are implementing:

1. llms.txt — SEO for AI Agents

Just as robots.txt tells search crawlers what to index, llms.txt tells AI agents what your product does. It’s a structured file at your domain root that provides:

Clear product descriptions
Feature lists
Pricing information
Integration capabilities
Documentation links

We’ve implemented this at luminarylane.app/llms.txt—and we recommend every brand do the same.

2. Structured Data That Machines Can Parse

Schema.org markup isn’t just for Google snippets anymore. AI agents use structured data to:

Understand your product category
Compare features against competitors
Verify claims (“Do they really integrate with Slack?”)
Extract pricing for comparison

Action item: Audit your JSON-LD. Is your product information machine-readable?

3. Verifiable Claims

AI agents are trained to be skeptical. They look for:

Third-party validation (awards, certifications, reviews)
Linked sources for claims
Consistent information across your site
Methodology explanations (“How do you calculate that ROI?”)

Vague marketing speak that works on humans falls flat with AI. “Industry-leading” means nothing without data to back it up.

4. API-First Content

If an AI agent is evaluating your product for a technical buyer, it may want to:

Query your capabilities programmatically
Check real-time availability or pricing
Test integrations before recommending

Brands with developer-friendly APIs and documentation have an A2A advantage.

What This Means for Your Marketing Team

The transition to A2A doesn’t mean abandoning human-focused marketing. It means adding a new layer:

Human Marketing	A2A Marketing
Emotional storytelling	Clear, factual descriptions
Beautiful visuals	Structured data
Social proof (testimonials)	Verifiable reviews (structured)
SEO for Google	SEO for AI agents (llms.txt)
Conversion-optimized landing pages	Machine-readable product specs

You need both. The human still makes the final decision—but increasingly, an AI agent is creating the shortlist.

The Competitive Advantage Window

Right now, A2A marketing is a blue ocean. Most brands haven’t even heard of llms.txt, let alone implemented it. The early movers who optimize for AI agent discovery will have a significant advantage as agent-assisted purchasing becomes mainstream.

Consider this: when ChatGPT, Claude, or a custom AI assistant recommends tools to millions of users, will your brand be in the consideration set?

Getting Started with A2A Marketing

Create an llms.txt file — Start with the basics: what you do, who it’s for, key features, pricing
Audit your structured data — Ensure your Schema.org markup is comprehensive and accurate
Make claims verifiable — Link to sources, show methodology, reference third-party validation
Think like an agent — Ask ChatGPT or Claude about your product category. Are you being recommended? Why or why not?
Monitor AI perception — Regularly check how AI agents describe your brand
