The 5 Pillars of Large Language Model Enhancement and Optimization

Jayne Schultheis — As artificial intelligence reshapes the way users discover and consume information, it also is fundamentally transforming online search. Traditional SEO best practices remain crucial for content marketing success, but today's marketers must also master the art of Large Language Model enhancement to stay competitive.

LLM optimization for content involves strategically crafting and structuring written material to maximize its effectiveness when processed, understood, and referenced by AI models like ChatGPT, Claude, and Bard.

The five essential elements of LLM optimization are:

• Topic authority
• Relevance
• Credibility
• Tactics
• Infrastructure

When content creators attend to these elements, AI systems are more likely to accurately extract key insights, maintain context, and present information in ways that serve user intent.

Nearly half of the employees surveyed in a McKinsey study reported they're not receiving adequate support or training in the use of AI tools. In this article, we'll show how to address the five pillars of LLM optimization to deliver relevant content. You'll learn how to create content that will be relevant to readers while providing clear, comprehensive, and contextually rich information that AI models can reliably interpret.

1. Topic authority and LLM optimization

Topic authority represents the depth and breadth of expertise that content demonstrates within a specific subject domain. It signals to both human readers and AI models that the content and your website are credible, comprehensive resources on the topic. It encompasses the interconnected web of concepts, subtopics, and related themes that collectively establish subject-matter mastery.

Anyone who makes content must attend to ​at least two things here:

Optimize for semantic discoverability, not just keywords.​

To optimize for semantic discoverability, you must go beyond keyword density to embrace conceptual clustering and entity relationships that mirror how AI models understand language and meaning. Instead of focusing solely on exact-match keywords, incorporate related concepts, co-occurring terms, and contextual entities that naturally appear together in authoritative discussions of the topic.

The idea is to create a rich semantic environment around the core subject matter. AI models recognize these patterns of conceptual association. Content that demonstrates comprehensive understanding through diverse but related vocabulary signals higher authority and relevance.

You should also structure content to address the "semantic neighbors" of your primary topic. That means addressing the questions, concerns, and subtopics that naturally arise in discussions among experts in your field. Then, LLMs can confidently identify your content as a comprehensive resource worthy of citation and recommendation.

Topical content depth and coverage​

This is the "full picture" treatment of a subject that addresses the primary topic and its underlying principles, practical applications, and broader implications within the domain.

AI models evaluate whether the content addresses the full spectrum of questions and considerations that an expert would naturally cover when they address a topic thoroughly.

To provide this depth, content should progress logically from basic definitions and core concepts to practical implementation details. This includes:

• Incorporating multiple perspectives.
• Addressing common misconceptions.
• Providing step-by-step guidance where applicable.
• Connecting the topic to real-world examples, related fields or emerging trends.

LLMs particularly value content that anticipates and answers follow-up questions and offers comparative analysis with alternatives. They prioritize actionable insights that demonstrate practical expertise over surface-level knowledge.

2. Relevance​ is still highly valued

Dan Boberg, Rellify's General Manager, Americas, explains that LLM optimization is still a fairly new concept, but some of its features are familiar. “Your typical CMO is not thinking about how they’re distilling the right text to place into a context window. But, essentially, what we’re talking about here is delivering relevant text for LLM context — context engineering. That’s the most important skill moving forward.”

Relevance is the degree to which your content directly addresses user intent and provides meaningful information that satisfies the specific needs behind a query.

Google's E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness) framework places tremendous emphasis on relevance. Content must be technically accurate, but also practically useful and appropriately targeted to the searcher's specific situation and level of knowledge.

AI models must quickly assess whether content provides the precise information needed to answer user queries accurately and completely. This is where leveraging a powerful AI writing tool becomes important.

Sophisticated platforms can analyze search intent patterns and identify content gaps. Then, they can help writers craft responses that precisely match the depth, tone, and focus that both human users and AI models expect for specific queries.

In terms of LLM optimization, however, there are a few ways you can keep your focus on relevance.

Consistent brand tone and voice​

For AI models, consistency in tone and voice is a crucial signal of content authenticity and brand authority. LLMs can detect patterns in sentence structure, vocabulary choices, and communication approach that indicate whether content genuinely represents a unified brand perspective.

To provide consistent brand tone and voice, content creators must establish clear guidelines that define their brand's personality traits, preferred terminology, level of formality, and approach to addressing different audience segments. This includes:

• Consistent use of industry-specific language.
• Maintaining the same level of technical depth across similar content types.
• Making sure that the brand's unique perspective and values are reflected in how topics are approached and explained.

LLMs favor brands that demonstrate consistency in blogging and other content. Some may use a conversational and approachable tone for consumer-facing content. Some may use a more technical and authoritative voice for B2B materials. The key is consistency. It helps AI models confidently associate the content with the brand and recommend it as a reliable source within the brand's domain.

Human editing

Any content can benefit from a critical layer of professional review and refinement. Editing can transform content, whether it's AI-generated or not, into authoritative, nuanced content that demonstrates genuine expertise and practical insight.

A human expert can:

• Identify and correct technical inaccuracies.
• Add industry-specific nuances.
• Incorporate current best practices.
• Make sure that content reflects the latest developments and practical considerations, which automated systems might miss.
• Add personal anecdotes, case studies, and examples.

AI models can detect and reward these improvements.

To provide effective human expert editing, organizations should engage professionals who possess both deep subject matter expertise and strong editorial skills.

Content freshness​

For AI models, freshness is an important quality, because LLMs are trained to prioritize recent, up-to-date information when they provide responses. This is particularly true for topics that change rapidly or where outdated advice could be misleading or harmful.

To keep content fresh, organizations should regularly review existing materials, focusing on:

• Updating statistical data with the latest available figures.
• Refreshing examples and case studies to reflect current market conditions.
• Incorporating new industry regulations or standards.
• Reflecting recent news.
• Adding current tool recommendations.
• Integration of recent industry shifts.

All of these signal to LLMs that the content represents the most current understanding and best practices in the field.

Content differentiation​

Your content needs a unique value proposition and distinctive perspective that sets it apart from the vast amount of similar information available online. Differentiation serves as a key indicator of content quality and usefulness. AI models are designed to identify and prioritize sources that provide:

• Novel approaches and frameworks.
• Proprietary research and data.
• Exclusive industry insights and expertise backed by evidence.
• Unique methodologies or frameworks.
• Original case studies from direct experience.
• Innovative solutions to common problems.

To strengthen content differentiation and personalization, leverage your unique market position and offer perspectives that competitors cannot easily replicate.

A content manager could focus on bringing creativity and innovation that a machine can't replicate. You also could use a content intelligence tool to find which themes, topics, and keywords can help differentiate your brand's content from the rest.

3. Credibility​ must be established and maintained

When your content demonstrates clear credibility markers, it creates a compounding effect. LLMs reference it more frequently, which builds your brand authority over time.

Peter Kraus, Chief Executive Officer of Rellify, says that credible content reflects the expertise and insider knowledge of an organization's best people. “The most valuable thing that any organization can do is to harness the expertise of the people in the company and codify their knowledge into an AI-driven architecture. It requires working with people and distilling their knowledge into a configuration that can drive AI engagement." 

AI-powered linking and PR tools are useful for creating interconnected authority signals. Advanced AI tools can identify optimal linking opportunities through semantic analysis. Some AI-powered PR systems can connect you with journalists and publications most likely to amplify your content and generate the credibility signals that LLMs value.

Here are some other ways you can boost your credibility with both LLMs and readers:

Integrate trust signals

Trust signals are verifiable indicators that help AI models distinguish credible content from unreliable sources. Think of them as digital credentials that demonstrate accountability and expertise.

Effective trust signals include:

• Author attribution. Display names, credentials, professional titles, and institutional affiliations that demonstrate subject matter expertise.
• Robust citation practices. Use proper formatting, link to original sources rather than secondary interpretations, include publication dates, and make sure all factual claims trace back to credible sources.
• Transparency. Make it easy for both humans and AI to verify the expertise behind your content.

Offer credible, verifiable facts

LLMs cross-reference factual claims against their training data and known reliable sources. That means accuracy is a critical factor for content visibility. Information that can be independently confirmed gives AI models the confidence to reference and recommend your content.

Prioritize sources like:

• Primary research.
• Official government data.
• Peer-reviewed studies.
• Established industry reports.
• Recognized expert statements.

Present statistics with clear attribution and publication dates, avoid hyperbolic claims, and fact-check all numerical data.

For emerging topics, distinguish between established facts and preliminary findings. Acknowledge data limitations and avoid presenting speculation as definitive fact.

LLMs reward intellectual honesty and precision. Content that demonstrates these qualities gets cited more frequently.

4. Tactics for LLM optimization

Even though LLM search is in its early stages, some tactics have been developed to optimize content for better AI model recognition and recommendation. The complexity and technical nature of these tactics highlight the tremendous value of an AI writing tool and comprehensive tech stack.

​These tactics include:​

Distilled header paragraph​

A distilled header paragraph is a concise, information-dense opening section that immediately gives AI models clear context about the content's main topic, scope, and key insights.

This tactical approach involves crafting the first paragraph to serve as a comprehensive summary. It should include the primary topic, key subtopics to be covered, and the most important conclusions or recommendations. This can enable LLMs to quickly assess the content's relevance and value for specific queries.

The distilled header paragraph should incorporate essential keywords naturally and maintain readability. The goal is to present the content's unique angle or perspective upfront. It also should provide enough context for AI models to understand how the content fits within the broader topic landscape.

Modular, multi-modal content

Modular, multi-modal content involves structuring information in discrete, purposeful sections that can be easily parsed and referenced by AI models while incorporating various content formats beyond traditional text.

This tactical approach includes:

• Q&A sections that directly address common user queries.
• Audio elements like podcasts or voice explanations.
• Visual components such as infographics or diagrams.
• Organizing content into clearly defined modules that can stand alone.

This approach allows LLMs to extract specific information segments that match user intent while providing multiple pathways for content discovery and engagement.

Schema markup​

Schema markup is structured data that provides AI models with specific information about content meaning, context, and relationships. It provides a more accurate interpretation and better visibility in search results.

It involves adding HTML tags that identify content elements — like articles, reviews, products, or FAQ sections — to  help LLMs understand the content's purpose and structure.

Effective schema markup includes:

• Relevant schema types for the specific content format.
• Accurate property values that describe the content's key attributes.
• Consistent implementation across all content pieces.

This tactic builds a comprehensive data framework that AI models can reliably interpret and use for improved content discovery and recommendation.

5. Infrastructure for an AI-first era​

As LLM search develops, the shift from traditional search to AI-driven information retrieval requires a fundamental rethinking of how systems are designed, deployed, and maintained.

Kraus, Rellify's CEO, says: “You’ve got to have the right infrastructure. If you have an AI first-infrastructure and your competitor doesn’t — guess what? Your content is going to outperform that of your rivals.”

The importance of AI-first architecture cannot be overstated in this context. Unlike traditional systems that bolt AI capabilities onto existing infrastructure, AI-first architecture is built from the ground up to support the unique demands of machine learning workloads. With this kind of approach, you'll focus on seamless integration between data pipelines, model serving, and real-time inference capabilities.

Distilled Expert Models / RAG / mCP Servers

Modern LLM infrastructure relies on three key architectural components that work together to deliver optimal performance:

• Distilled Expert Models.These smaller, specialized models are trained to capture the essential knowledge of larger foundation models while requiring significantly less computational resources. By focusing on specific domains or tasks, distilled models deliver comparable performance to their larger counterparts while reducing inference costs and improving response times.
• Retrieval-Augmented Generation (RAG). These systems bridge the gap between static model knowledge and dynamic, real-time information. RAG architectures combine vector databases with embedding models to retrieve relevant context that supplements the LLM's training data. This approach allows models to access current information, reduce hallucinations, and provide more accurate, contextually relevant responses without requiring constant retraining.
• Model Context Protocol (mCP) Servers. These provide a standardized way for AI systems to access external tools and data sources. They act as intermediaries for LLMs to interact with databases, APIs, and other services in a secure, controlled manner.

Prepare for agent-based journeys

You might have heard "Agentic AI" or "AGI" being talked about in your circles, and for a good reason. It's the projected path of LLMs as they progress toward more autonomy. You can think of AI agents as digital employees who never sleep. Instead of just answering questions, these agents can automate entire workflows with limited intervention.

Take automated quoting, for example. An AI agent can chat with a potential customer, pull pricing from your database, crunch the numbers, and even update your CRM, all without bothering your sales team.

However, your infrastructure needs to be ready for this shift toward automation. These agents need systems that can keep track of where they are in complex processes and bounce back when something goes wrong. Your APIs need to be compatible with AI behavior patterns, which can be quite different from how humans interact with systems.

The good news? Once you nail the infrastructure, you can iterate and improve your agents quickly as the technology evolves.
