Key Takeaways

LLM SEO is changing how brands earn visibility online.

In the past, SEO was about ranking pages in Google, getting into SERP features, and competing for clicks. Today, many users skip the search results entirely and ask AI tools for direct answers instead.

ChatGPT, Claude, and Gemini now play a big role in how people research products, learn new concepts, and make decisions online.

According to Menlo Ventures, over 60% of U.S. adults have used AI tools to find information in the last six months, with nearly 20% using them daily.

If your content isn’t structured, credible, and easy for AI to understand, you risk being left out of the conversation.

LLM SEO focuses on making your brand a source that AI systems trust, reference, and cite.

After reading this guide, you’ll know how to improve LLM SEO, how to measure it, and mistakes you definitely want to avoid making when optimizing for LLM SEO.

What is LLM SEO?

LLM SEO (Large Language Model Search Engine Optimization) is the process of creating and structuring content to maximize the likelihood of being referenced, cited, or recommended by generative AI models.

While traditional SEO mainly focuses on keywords and backlinks to rank a webpage, LLM SEO focuses on entities, context, and authority.

The goal of LLM SEO is to be the source that the AI uses to construct its answer.

This is often referred to as Generative Engine Optimization (GEO) or Answer Engine Optimization (AEO).

Regardless of the acronym, the objective remains the same: winning citations in AI-generated responses.

How to Improve LLM SEO

Optimizing for AI requires a blend of traditional technical SEO and some specific tactics to content creation and content formatting.

1. Create Content that is Easy to Access

If an AI system can’t access your content, it can’t reliably cite or reference it in live answers.

LLMs are trained on massive datasets, which means they may already know of well-known brands, products, or concepts from past training.

However, when AI systems generate current, source-backed answers, they often rely on live web retrieval.

That’s where accessibility matters. If your site is blocked, hard to crawl, or poorly indexed, your content is far less likely to be cited or linked as a source.

Start with these fundamentals:

Check Your Robots.txt File

Make sure you aren’t accidentally blocking AI-related crawlers such as GPTBot (OpenAI), ClaudeBot (Anthropic), or Google-Extended.

Ensure Your Site is Indexable and Crawl-Friendly

Important content should not be hidden behind heavy scripts, login walls, or blocked resources.

Optimize for Bing

ChatGPT Search relies on Bing-powered search for live retrieval. If your site performs poorly in Bing SEO or isn’t properly indexed, your chances of appearing in AI citations decrease.

Setting up Bing Webmaster Tools helps ensure your site is healthy and discoverable.

Experiment with Llms.txt (Optional)

Some publishers are experimenting with an llms.txt file to provide a simplified overview of key content for AI systems.

2. Establish Trust and Expertise on Your Own Website

AI systems are designed to rely on information that appears accurate, credible, and well-sourced. If your website doesn’t clearly demonstrate expertise, it’s unlikely to be cited in AI-generated answers.

To improve your chances of getting cited, you must prove you are an authority in your niche and industry.

Show Clear Authorship and Credentials

Every article should have a named author, a short bio, and links to relevant credentials such as LinkedIn profiles, professional experience, or subject-matter expertise.

Demonstrate First-Hand Experience

AI systems favor content that includes original insights, examples, screenshots, case studies, or real-world observations and not generic summaries anyone could write.

Speak from your experience within your writing. "Based on testing..." as an example. LLMs love first-hand experience.

Use AI Carefully

AI tools can help with research or drafting, but content should not be purely AI-generated.

To stand out, your pages must add unique context, opinions, or data that isn’t already widely available.

Reference Reliable, Primary Sources of Data

Linking to original studies, official data, and authoritative organizations helps reinforce accuracy and signals that your content is grounded in facts.

Better yet, brands that publish their own data studies with insights from customers and internal data tend to have a higher chance of being featured in AI answers.

Publishing original data also helps a lot. When you share your own stats or benchmarks, you naturally become the source people reference. AI systems seem to favor that.

3. Make Your Website Easy for AI to Understand

Once AI systems can access your site, the next step is helping them clearly understand what your content is about.

LLMs analyze text using natural language patterns and structure.

Content that is clearly written, well-organized, and properly marked up is easier for them to interpret, summarize, and reuse in answers.

Optimizing for LLMs requires a mindset shift mostly because LLMs don’t “rank” content the way Google traditionally does; instead, they retrieve, summarize, and cite content based on clarity, authority, and structure.

You can improve clarity in a few practical ways:

Use Structured Data where it Makes Sense

Schema markup helps describe the type of content on a page, such as articles, FAQs, products, or your organization.

For example, check the below screenshot of FAQ schema on a personal injury lawyer's website:

Write in a Clear, Direct Way

Use simple language, avoid unnecessary jargon, and structure headings around real questions users ask.

Rachel Amies is an AI Visibility & SEO strategist at Crazy Digital Creative and she believes marketers should write like they're speaking to their ideal client, not a search engine.

LLMs are trained on natural human language. They favour content that flows nicely and is genuinely helpful. If your page reads like it was written to impress industry colleagues (i.e. full of jargon), it won't impress Google or LLMs.

Use Proper HTML Structure

Clear H1, H2, and H3 headings, short paragraphs, bullet points, and tables help AI systems break content into logical sections.

Well-structured pages are easier to extract answers from than long, unformatted blocks of text.

4. Get Mentioned on Other Trusted Websites

AI systems don’t rely on what a single website says about itself. They look for confirmation across multiple sources to decide whether a claim is reliable.

If your website says you’re the best option in your category, that’s treated as a self-claim. When other reputable websites repeat similar descriptions or mention your brand in the same context, that claim becomes far more credible.

To strengthen these external signals, focus on the following:

Focus on Digital PR and Third-Party Mentions

Aim to be included in “best of” lists, product reviews, comparison articles, and industry publications.

Be Present in Forums and Communities

Platforms like Reddit, Quora, and Stack Overflow reflect real user questions and opinions.

If you want Large Language Models to notice you, you need to go where they are. Overwhelmingly, the best place to go is Reddit. The other platform where we have seen success is Quora.

What is the Difference between Traditional SEO and LLM SEO?

Traditional SEO helps your website rank, whereas LLM SEO helps your brand get cited in AI-generated answers.

How to Measure LLM SEO Performance

Measuring success in Generative AI is more difficult than traditional SEO because there is currently no official analytics tool from ChatGPT, Claude, or Gemini.

However, there are some ways to track your progress:

1. Monitor Referral Traffic

Check Google Analytics 4 (GA4) for referrals from chatgpt.com, perplexity.ai, and claude.ai.

Common LLM SEO Mistakes to Avoid

In the rush to adapt to AI search, many marketers make errors that hurt their visibility.

Vague Content

LLMs struggle with ambiguity. Content that uses fluff phrases like "innovative solutions" or "cutting-edge technology" without explaining what the technology is will be ignored.

No Clear Authorship or Credibility

If an article looks anonymous, AI models assign it lower trust scores.

Publishing without Distribution

You cannot simply publish a blog post and hope ChatGPT finds it.
