Large language models (LLMs) are transforming the way people search for information online. These AI systems are trained on massive amounts of text, enabling them to understand and generate human-like language. They power both generative search and conversational search, making it possible for users to interact with AI tools in ways that go far beyond traditional search engines.

  • Generative search: Produces natural-language responses to queries, such as Google AI Overviews.
  • Conversational search: Enables back-and-forth dialogue between the user and the AI, like ChatGPT or Google AI Mode.

For simplicity, many marketers refer to AI-powered search tools themselves as LLMs, and that’s what we’ll do here. In this guide, you’ll learn why LLM optimization (LLMO) matters, how it can elevate your brand’s visibility, and practical tactics to improve your presence in AI-generated responses.

What Is LLM Optimization?

What Is LLM Optimization

LLM optimization (LLMO) is a marketing strategy focused on enhancing your brand’s visibility and portrayal in responses generated by LLM-powered search tools. These responses increasingly appear in Google AI Mode, ChatGPT, Microsoft Copilot, and other AI platforms.

At its core, LLMO involves two main approaches:

  1. Getting positive brand mentions on widely cited websites. This helps LLMs understand your brand better and portray it favorably.
  2. Creating original, useful, and AI-friendly content increases the likelihood that LLMs will cite or reference your content when answering user queries.

Many of the traditional SEO techniques still apply to LLMO, but additional strategies specific to AI models can further boost your visibility.

Why LLM Optimization Matters

The rise of AI-powered search has changed how users interact with information. LLMs often appear at the top of search results, providing concise, natural-language answers directly to users. According to Semrush’s AI Search Study, the average AI search visitor is 4.4x more valuable than a traditional organic search visitor.

Benefits of LLMO include:

  • Increased brand awareness: Users see your brand in AI-generated answers, even if they don’t click through immediately.
  • Improved brand reputation: Positive mentions on authoritative sites influence how LLMs present your business.
  • Higher revenue potential: AI-driven recommendations can drive qualified traffic and conversions.

LLMO not only provides immediate benefits but also secures a long-term advantage. AI adoption is increasing rapidly, and the information you provide now could be incorporated into future LLM training datasets, influencing how your brand is referenced for years to come.

How Often Do Users See LLM Responses?

AI-generated content is becoming mainstream. In March 2025, 13.14% of U.S. Google search results pages displayed LLM responses, often right at the top.

Additionally, conversational AI platforms such as ChatGPT, Microsoft Copilot, Perplexity, and Claude collectively drew over 600 million unique visitors in May 2025. Exposure is only expected to grow as AI adoption rises and platforms like Google AI Mode, which mimics a ChatGPT-like experience, become more widespread.

By 2027, LLM-powered responses are projected to become major drivers of both traffic and revenue. Marketers need to adapt now to AI search optimization to maintain and improve visibility.

How Marketers Can Adapt

Adapting to LLM-powered search requires learning to optimize for AI search tools and tracking performance across platforms. Tools like Semrush Enterprise AIO allow marketers to monitor brand mentions, measure AI visibility, and analyze competitor performance.

Practical LLM Optimization Techniques

Here’s a detailed breakdown of actionable LLMO strategies:

1. Get Brand Mentions on Commonly Cited Websites

LLMs prioritize content from authoritative and frequently cited sources. Identifying the top sites in your niche that LLMs reference, like Quora, Reddit, and industry-specific blogs and getting your brand mentioned there is key.

How to monitor mentions:

  • Manually track citations by performing searches on AI platforms.
  • Use tools like Semrush Enterprise AIO for automated, real-time monitoring of mentions, sentiment, and visibility.

Digital PR and link-building strategies can help secure valuable exposure. Chris Tweten, CMO at Spacebar Collective, explains:

“We track which pieces of media become citations in ChatGPT, Gemini, and Perplexity. Traffic from these platforms is converting at around 30% for one of our clients.”

2. Establish a Unique Value Proposition (UVP)

A strong UVP sets your business apart and gives LLMs a reason to mention your brand. Whether it’s competitive pricing, superior product quality, or an exclusive service, clearly communicating your UVP across:

  • Your website
  • Social media channels
  • Industry forums and communities

…can increase the likelihood of being cited by LLMs. For saturated markets, this tactic is particularly critical.

3. Create Original and Useful Content

LLMs prioritize content that is both original and highly relevant. Content customized to specific user intents, especially complex prompts that competitors may not addres,s can improve your brand’s visibility in AI-generated answers.

Tips for content creation:

  • Address all stages of the marketing funnel.
  • Top-of-the-funnel audiences often engage with conversational AI for impartial guidance, so aim to be cited early.
  • Ensure your content is informative, actionable, and authoritative.

4. Make Your Content Accessible to LLMs

AI models need access to your content to cite it. This means:

  • Using server-side rendering rather than relying heavily on JavaScript.
  • Making content publicly accessible—paywalls and login requirements prevent AI ingestion.
  • Following technical SEO best practices which indirectly improve AI visibility.

Jeremy Howard proposed the concept of an llms.txt file to standardize AI access to content, similar to robots.txt, though adoption is not yet widespread.

5. Incorporate Images and Videos

Multimodal content (images, videos, infographics) can boost LLM visibility by:

  • Providing richer context for AI understanding.
  • Enhancing user engagement and demonstrating expertise.
  • Aligning with LLMs capable of multimodal searches, like Google AI Mode.

Make sure all visual content includes descriptive text, so LLMs can interpret and reference it correctly.

6. Optimize Content at the Passage Level

LLMs often use passage-level retrieval, meaning they extract information from individual sections rather than entire documents.

Best practices:

  • Be specific in each passage.
  • Ensure passages make sense independently.
  • Stay focused on one topic per passage.
  • Use subheadings to structure related content logically.

This approach allows multiple documents to collectively support AI citations, instead of relying on a single comprehensive page.

7. Tailor Content to Target Audiences

Many LLMs provide personalized responses based on user profiles. Tailoring content to specific audiences increases the chances of being mentioned in AI-generated answers.

  • Identify key audience segments using Semrush Traffic & Market Toolkit.
  • Address user intent in content to align with conversational AI queries.
  • Leverage past interactions, if memory-enabled AI tools are in use, to reinforce relevance.

8. Manage Your Online Reputation

LLMs learn about your brand from online content. Negative mentions may influence AI responses just as much as positive ones.

Tips for reputation management:

  • Respond to reviews strategically.
  • Encourage positive customer reviews.
  • Provide excellent customer service.
  • Leverage digital PR and influencer marketing.
  • Monitor LLM sentiment using tools like Semrush Enterprise AIO.

Tracking LLM Visibility

Tracking LLM search performance differs from traditional SEO because:

  • Prompts are more specific and conversational than keywords.
  • Personas matter. AI responses can be personalized.
  • Multiple AI models exist, so visibility must be monitored across platforms.

Software like Semrush Enterprise AIO can generate brand-specific prompts, measure AI visibility, track sentiment, and provide insights into competitor performance.
