Content for Two Audiences: Writing for Humans and AI

Here's a number that should change how you think about content:

This isn't a trend line. It's a structural shift.

For three decades, content strategy has meant one thing: write for humans, optimize for search engines. The search engine was a sorting mechanism that matched human queries to human-readable pages. The audience was always, ultimately, a person.

That's no longer true.

Now you're writing for two audiences simultaneously:

1. Humans who read your blog posts, watch your videos, and scroll your landing pages
2. AI systems that parse your content to answer questions, make recommendations, and — increasingly — make purchasing decisions on behalf of humans

The skills are different. The formats are different. And the marketers who figure out how to serve both audiences will have a significant advantage over those still optimizing for one.

The Shift: From SEO to GEO

The industry is starting to call this Generative Engine Optimization (GEO) — the practice of structuring content so that AI systems can accurately understand and represent it.

What works for GEO is fundamentally different from what worked for SEO:

What AI Systems Actually Need

When an AI assistant tries to answer a question about your product, it's looking for specific types of information in specific formats. Here are the four requirements:

Before & After: Product Description

Let's make this concrete. Here's how the same product information looks when written for humans only versus written for both humans and AI.

Example 1: Product Overview

What changed: The "Before" version is pure marketing copy — emotionally appealing but informationally empty. An AI assistant asked "What does Acme Analytics do and what does it cost?" would struggle to extract a useful answer.

The "After" version answers specific questions directly: what it is, what it's for, how it deploys, what it connects to, what it costs. An AI can parse this and accurately represent it.

Example 2: FAQ Structure

What changed: The "Before" version takes 80 words to not answer the question. The "After" version leads with a direct answer (Yes), then provides specifics an AI — or a human — can actually use: what's included, how long it takes, where to learn more.

Example 3: Competitive Positioning

What changed: The "Before" version makes vague claims with no specifics. An AI asked "How does Acme compare to Tableau?" would get nothing useful.

The "After" version names competitors directly, acknowledges their strengths honestly, and provides clear guidance on fit. This is exactly what an AI needs to give an accurate comparison — and what a human evaluator actually wants to know.

The Schema Layer: Making It Machine-Readable

Beyond writing style, there's a technical layer that makes content truly AI-accessible: structured data markup. This is how you tell AI systems — explicitly — what your content means.

// Schema.org markup for a SaaS product page
{
  "@context": "https://schema.org",
  "@type": "SoftwareApplication",
  "name": "Acme Analytics Platform",
  "applicationCategory": "BusinessApplication",
  "operatingSystem": "Web-based (Cloud)",
  "offers": {
    "@type": "AggregateOffer",
    "lowPrice": 70,
    "highPrice": 150,
    "priceCurrency": "USD",
    "priceSpecification": {
      "@type": "UnitPriceSpecification",
      "billingDuration": "P1M",
      "unitText": "per user"
    }
  },
  "featureList": [
    "SQL-based analytics",
    "Dashboard creation",
    "Embedded analytics",
    "Salesforce integration"
  ]
}

This markup sits invisibly in your page's HTML, but it tells AI systems exactly what your product is, what it costs, and what it does — in a format they can parse programmatically.

The Dual-Audience Framework

Here's how to think about creating content that serves both audiences:

Layer 1: Human-First Content

This is what you're already doing. Narrative storytelling, brand voice, emotional resonance, visual design. The content that makes humans want to engage, trust, and buy. Don't abandon this.

Layer 2: Machine-Readable Substrate

Underneath the human-readable layer, add structured data that AI can parse:

• Schema.org markup on product pages
• Structured FAQs in addition to prose explanations
• Clean JSON for product specifications
• Consistent taxonomy and naming conventions

Layer 3: API-Ready Data

For organizations ready to go further: actual endpoints that AI agents can query for real-time information. Pricing APIs, inventory checks, integration compatibility — the infrastructure that lets agents transact, not just research.

Test Your Current AI Visibility

Before you start optimizing, establish a baseline. Here's a simple audit:

1. Query three AI assistants — Ask Claude, ChatGPT, and Perplexity: "What is [your product]? How does it compare to [competitor]? What does it cost?"
2. Score the responses — Are they accurate? Complete? Do they mention your key differentiators? Or do they hallucinate, omit you entirely, or get basic facts wrong?
3. Identify the gaps — Where is the AI getting it wrong? That's where your content is failing to communicate clearly.
4. Check your competitors — How do they show up in the same queries? Better or worse than you?

This 30-minute exercise will tell you exactly where to focus your GEO efforts.
