Prompt-Based Keyword Research in SEO (2025 Edition)

The world of search is evolving faster than ever. With AI-driven platforms like ChatGPT, Gemini, and Bing AI shaping how users query information, businesses can no longer rely only on traditional keyword research. This is where prompt-based keyword research comes in.

Instead of targeting “short” or “long-tail keywords,” marketers now analyze prompts—full conversational queries users feed into AI tools. These prompts often mirror search intent more deeply than a standard keyword. Optimizing for prompts means anticipating real conversations people have with AI assistants and aligning your content accordingly.

Evolution of Keyword Research

Traditional SEO relied heavily on tools like Google Keyword Planner, Ahrefs, and SEMrush to uncover keyword volumes and competition. Marketers built content strategies around high-volume keywords and long-tail variations.

But now:

• 70% of Gen Z users prefer conversational search. (Statista, 2024)
• Google’s AI Overviews and Bing’s AI Copilot reshape queries into more natural prompts.
• Voice assistants like Alexa, Siri, and Google Assistant process queries as full sentences, not short keywords.

The takeaway? Keyword research must evolve beyond lists of terms—it must embrace AI prompt behavior.

What is Prompt-Based Keyword Research?

Prompt-based keyword research is the process of identifying and optimizing for the natural language prompts users input into AI systems and search engines.

Example difference:

Notice how the second one contains:

• Context (small businesses)
• Time relevance (2025)
• AI-specific needs

By targeting such prompts, content creators match intent more precisely, leading to better visibility in AI-generated results.

Understanding Prompt-Based Keyword Research Ecosystems

A prompt ecosystem refers to the collection of queries, variations, and conversational flows around a specific topic. For instance, in AI-driven searches, a user rarely asks just one question. They refine, expand, and continue the dialogue.

Example (Prompt Ecosystem for “Eco-Friendly Marketing”):

1. “What is eco-friendly marketing?”
2. “Give me examples of eco-friendly marketing campaigns in retail.”
3. “Which companies in Canada use sustainable advertising practices?”
4. “How can I apply eco-marketing strategies to my eCommerce store?”

Each of these represents different layers of the same ecosystem. Optimizing your content to cover the entire ecosystem helps AI engines recommend your site repeatedly.

Zero Search-Volume Prompts: Hidden Opportunities

Traditional SEO ignores zero search-volume (ZSV) keywords because they don’t appear in keyword tools. However, in AI-driven ecosystems, these are goldmines.

Why?

• New prompts don’t yet have measurable data, but early adopters dominate rankings.
• AI models learn from available content. If yours is the only one optimized for that prompt, your chances of surfacing increase.

Example:

Instead of “remote team software,” a zero-volume prompt might be:
👉 “What’s the best AI-powered remote team collaboration software under $50/month for startups?”

This long, specific query may not appear in keyword tools, but real users are typing it into ChatGPT and Bing AI. Brands who target it win by being first.

Tools to Find Prompt Volume

Since Google Keyword Planner and SEMrush don’t fully support prompt analysis, new tools are emerging.

Pro Tip: Use Google Search Console to track rising queries where impressions are growing but volume looks low. These are prompts in disguise.

How to Create Content Around Prompts

Content should be structured to answer conversational prompts directly.

Guidelines:

• Use FAQ Schema to cover natural Q&A.
• Include examples, comparisons, and case studies.
• Write in conversational tone while maintaining authority.
• Add content depth (tables, stats, multimedia) to match user expectations.

Example Prompt → “How do AI-powered SEO tools compare to traditional ones?”

Content Structure:

• H2: Comparison Table (AI vs Traditional SEO)
• H3: Case Study (AI adoption in small business)
• H3: Pros & Cons (Bullet Format)

This ensures your content is “AI-digestible” and surfaces in results.

Case Studies & Real-World Examples

Case Study 1: SaaS Startup
A SaaS startup targeted zero-volume prompts like:
👉 “Best invoicing tools for digital nomads in Bali.”
They published optimized blogs + schema data. Within 3 months, they captured high-value, low-competition traffic and were featured in Bing AI results.

Case Study 2: Healthcare
A clinic used prompt-based optimization around:
“What is the safest telemedicine app for seniors in Canada?”
Despite zero search volume initially, within 6 months they ranked for 1,200 monthly visits after AI Overviews surfaced their content.

SEO + AEO + Prompt-Based Keyword Research Strategy (Hybrid Approach)

To future-proof content, use a hybrid strategy:

• SEO (Search Engine Optimization): Capture traditional traffic with keywords.
• AEO (Answer Engine Optimization): Optimize for AI tools (ChatGPT, Perplexity, Bing Copilot).
• Prompt Optimization: Anticipate conversational prompts and ecosystem queries.

This approach ensures visibility across Google, Bing, AI assistants, and future LLM-based engines.

Technical Enhancements

Schema Markup for Prompts

Use FAQ and HowTo schema to align with AI-driven queries.

Example JSON-LD FAQ Schema:

{
  "@context": "https://schema.org",
  "@type": "FAQPage",
  "mainEntity": [{
    "@type": "Question",
    "name": "What is prompt-based keyword research?",
    "acceptedAnswer": {
      "@type": "Answer",
      "text": "Prompt-based keyword research focuses on identifying natural language queries users ask AI tools, helping businesses target conversational search."
    }
  }]
}
