What Is an LLM?
A Large Language Model (LLM) is an advanced type of artificial intelligence that processes and generates human-like language. Think ChatGPT, Gemini, Claude – these models scan massive datasets to understand language patterns and deliver text-based outputs. In digital marketing, they're the driving force behind generative search, AI assistants, and increasingly, how users discover content.
What Is LLM SEO?
LLM SEO (Large Language Model Search Engine Optimization) is the strategic practice of optimizing your digital content to be surfaced, summarized, or referenced by LLMs. It’s not just about ranking on Google’s SERPs anymore—it’s about being cited in AI-generated answers across platforms like ChatGPT, Perplexity, Gemini, and even Google’s own AI Overviews (formerly SGE).
Traditional SEO focuses on winning page-one rankings. LLM SEO ensures your content is chosen by generative engines as trustworthy, relevant, and high-quality enough to influence or directly appear in AI responses.
LLM SEO Strategies That Can Work
1. Optimize for Authority, Experience, and Trust (E-E-A-T)
Generative engines favour brands that demonstrate credibility. That means:
-
Getting backlinks and brand mentions from reputable sources.
-
Publishing expert-level content supported by case studies, whitepapers, or first-party data.
-
Building out profiles on LinkedIn, YouTube, and industry directories with consistent NAP data.
2. Create AI-Friendly Content Structures
LLMs love well-structured, semantically rich content. That includes:
-
Using clear headers and concise paragraphing.
-
Including definitions, FAQs, and “how-to” style content in plain language.
-
Embedding schema markup and structured data to aid context.
3. Think in Terms of Topics, Not Just Keywords
Generative engines don’t rely on keyword density—they infer intent. That means shifting your content strategy from chasing individual keywords to building deep, interconnected topic clusters.
4. Be Discoverable – Everywhere
While Google still dominates, platforms like ChatGPT and Perplexity are gaining traction. Ensure your content is crawlable and visible across multiple platforms—YouTube, Reddit, Quora, GitHub, and more. LLMs ingest from a broad spectrum of public content—not just your website.
5. Leverage Content Refresh Cycles
LLMs prioritize recency in their responses. Refresh your cornerstone content regularly with new insights, updated stats, and original research to increase your inclusion odds in AI-generated summaries.
LLM SEO vs Traditional SEO: What’s the Difference?
LLM SEO builds on traditional SEO fundamentals—but with a generative twist:
-
Focus: Traditional SEO is about search engine rankings. LLM SEO is about being referenced or summarized in AI-generated answers.
-
Metrics: SEO success is measured in rankings and traffic. LLM SEO success is measured in visibility within AI outputs, brand mentions, and indirect traffic/referral lift.
-
Distribution: SEO typically emphasizes Google SERPs. LLM SEO expands to AI engines, voice search, and emerging assistant-based interfaces.
The two disciplines are complementary. A solid SEO foundation amplifies your LLM SEO potential—but ignoring generative engines in 2025 means leaving serious brand visibility on the table.
