LLM SEO Prompt Library

What Is LLM SEO and Why It Matters in 2026

LLM SEO (also called AI SEO or answer-engine optimization) is the practice of structuring your content so large language models—like ChatGPT, Claude, Gemini, Perplexity, and Google AI Overviews—can easily understand, trust, and surface it in their answers.

Core Principles of LLM SEO-Optimized Content

1. Intent-First, Not Keyword-First

LLMs care about search intent—what the user really wants to know. Your prompts should always specify who the content is for, what problem they're solving, and what format best solves it.

2. Structure and Scannability

Both Google and LLMs parse content better when it's structured with clear headings, short paragraphs, bullet lists, and occasional tables.

3. Semantic Richness and Topical Coverage

Modern SEO is about topic clusters, not just repeating a keyword. Include related subtopics, entities (tools, frameworks, brands, concepts), and FAQs.

4. Direct, Snippet-Friendly Answers

AI Overviews and Perplexity often lift short, direct answers. Use clear question → direct answer format in 40–80 word chunks that can stand alone.

Master Prompt Framework for LLM SEO Content

"You are an expert writer and SEO strategist.
I need an article optimized for both:
– LLM SEO (AI Overviews, Perplexity, ChatGPT answers)
– Google SEO (organic search)

Topic: [insert topic or long-tail keyword]
Audience: [describe who they are, their level, what they want]

Requirements:
- Start with a 2–3 sentence overview that directly answers the core question
- Use clear, descriptive H2 and H3 headings that match real search queries
- Include at least 10 natural-language questions and concise answers
- Cover related subtopics and entities for topical depth
- Use short paragraphs, bullet lists, and at least one table where comparisons help
- Naturally incorporate these keyphrases: [list 5–10 related phrases]
- End with practical steps or a checklist the reader can follow
Output in markdown. Prioritize clarity and concrete examples."
