LLM Optimization Guide for CMOs and Marketers in 2025

We’re halfway through 2025, and we know one thing for sure: digital visibility is being redefined at breakneck speed. As search evolves from keyword-based queries to AI-assisted answers, brands are asking one key question: LLM SEO vs Traditional SEO: What Marketers Must Prioritise in 2025?

SEO has long been the foundation of digital growth. However, with Large Language Model Optimization (LLMO) emerging as a serious contender for attention - particularly on AI platforms like ChatGPT, Gemini, Claude, and Perplexity - marketers must adapt quickly.

This rise of LLM optimization is reshaping how content gets discovered.

What is LLMO and Why It Matters

The term LLM optimization is now gaining traction among marketers who are adapting their content strategies specifically for visibility on AI-powered search interfaces. Unlike traditional SEO, LLM optimization focuses on optimizing content to be retrieved, summarised, and cited by generative engines. This means clarity, structured context, and citation-ready formats are no longer optional; they are essential.

Instead of showing a list of links, they generate direct responses to user queries based on a mix of public information, licensed data, and in some cases, the web content they’ve been trained on or are connected to.

For your content to appear in those responses, it needs to follow certain principles:

• It should be clear, accurate, and easy to understand
• It must be well-organized, covering important points in full
• It should mention real people, places, and terms that give context
• It must follow a logical structure so the AI can understand and retrieve it effectively

As more users turn to conversational generative engines instead of search engines, LLMO helps ensure your content is included in those AI-generated answers. This offers businesses a new way to stay visible, even when users never see a traditional search results page.

Answer Engine Optimization (AEO) has emerged as an important extension. The rise of voice search and AI-driven tools has made it clear that people are now looking for direct answers, not just a list of links. AEO works by structuring content in a way that directly answers user questions, making it easier for these tools to find and use.

This shift from focusing on ranking for general keywords to addressing specific user intents is a key change in SEO. And with the rise of LLMO, the need for clear, factual, and machine-readable content has become even more important, as it helps ensure that content is picked up by AI systems for accurate responses. As part of comprehensive Digital Marketing Services, LLMO and AEO are becoming essential strategies for businesses that want to stay visible in the evolving search landscape.

According to Exploding Topics, as of March 2025, 13.14% of all queries generated an AI Overview. And of all the queries that do trigger an AI Overview, 88.1% are informational.

On a different front, a report released by Bain & Co. approximately 80% of U.S. consumers are already using AI-generated content for at least 40% of their searches.

These numbers are massive and indicate seismic shifts in user behaviour, and they signal the need for brands to make immediate pivots to increase their visibility with their customers.

The Impact of Modern SEO in Driving Business Growth

SEO has always been about visibility, but in 2025, its role extends beyond ranking. It now shapes digital experiences, builds trust, and attracts high-intent users. Modern SEO combines content depth, backlink authority, and technical health to boost brand discoverability.

By focusing on building topical authority, aligning with user search behavior, and meeting E-E-A-T standards, SEO enhances brand credibility and improves UX metrics like page speed and mobile-friendliness. Structured data and schema markup further optimize content for search results.

SEO vs LLMO: What’s the Real Difference?

At first glance, SEO and Large Language Model Optimization (LLMO) may seem similar. Both help users find information. But the way they work and where your content appears is very different.

SEO focuses on helping your website rank on search engines like Google or Bing.

SEO also involves using the right keywords, improving site speed, gaining backlinks, and creating helpful content. Success is measured by your page rankings, traffic volume, and how users interact with your site.

In contrast, LLMO works with generative engines that give full answers and follow up steps rather than showing a list of links.

Generative engines like ChatGPT, Gemini, and Perplexity tend to use your content if it is factual, well-structured, and trustworthy. Consequently, LLMO requires a strong and active digital PR strategy because generative search engines often reference news and media sites along with business listing platforms.

This is where LLM optimization comes in, acting as the SEO-specific component of LLMO. It focuses on making your website content optimized for AI-generated answers, blending traditional SEO tactics with AI-readability.

This shift changes how people find and trust information.

As it stands now, the impact of LLMO on SEO strategies is becoming clear. Brands that rely only on traditional rankings risk losing visibility in the growing space of AI-assisted search.

How LLMO Is Reshaping Digital Marketing

We’ve already established that the way users find answers online is changing. Increasingly, they ask questions in plain language and expect fast, accurate responses without needing to scroll through multiple websites.

One major example is Google’s AI Overviews, which summarise search results into short, snapshot answers. These often appear at the top of the page, reducing clicks on traditional listings.

More people are also using voice search or generative engines like ChatGPT, Gemini, or Perplexity. Instead of browsing, they receive direct answers compiled together from reliable sources.

The implication for brands is evident. They must adapt to getting fewer clicks and focus now on gaining visibility on LLMs. The focus needs to shift to converting potential customers when the AI-generated traffic lands on their websites.

According to recent projections from Semrush, AI-assisted searches are expected to surpass traditional search in delivering website visitors by 2028.

This rapid shift underlines why businesses cannot depend solely on ranking in search engines but must also prepare their content for AI-powered discovery engines.

Generative engines  do not show ten blue links. Instead, they offer a better user experience by way of asking for fewer follow up queries; their answers are more complete and context rich. It’s one reason why AI search engines have been adopted so quickly. And also why AI-assisted search is poised to surpass traditional search.

To be included on generative engine search results, your content must be easy to understand and written in a way that machines can interpret confidently.

In this new landscape, LLMO becomes an essential part of digital strategy. It helps your content become part of these new answers, an increasingly common way people access information in 2025.

Why Smart Brands Are Combining SEO and LLMO

In 2025, businesses do not have to choose between SEO and LLMO.

The smartest approach is to combine both, ensuring visibility across traditional search engines and AI-driven platforms.

SEO helps bring steady, high-quality traffic by ranking well for keywords. It builds long-term authority and performance through time-tested practices.

LLMO ensures your content is present in the growing space of AI-generated answers. It helps your brand get discovered even when users do not land on your website directly.

"We are no longer optimizing only for algorithms; we are now optimizing for conversations. As AI platforms like ChatGPT, Gemini and Perplexity change how users consume information, brands need to adapt their content to remain part of these new discovery journeys. The future belongs to businesses that combine the proven discipline of SEO with the emerging science of LLMO. This hybrid approach ensures visibility, trust, and sustained growth in both search engines and AI-driven answers." - Sarvesh Bagla, CEO, Techmagnate

The Future of Visibility Is Hybrid

The debate around SEO vs LLMO is not about choosing one over the other, it’s about recognising that digital discovery has evolved. Search is no longer a single channel; it’s a blend of human queries, machine answers, and AI-driven journeys.

That’s why the future of digital marketing is hybrid. SEO continues to drive long-term authority and organic growth. LLMO is enabling visibility in AI-generated answers. Together, they form a new baseline for discoverability. It’s no surprise that more brands are now exploring AI SEO services, not as a replacement for SEO, but as an essential layer that optimizes content for both users and machines.

Beyond SEO vs LLM Optimization: AEO, GEO, and the Emerging Visibility Stack

 Zooming out, the landscape is getting even more layered. It’s no longer just about SEO vs LLMO; marketers need to learn the difference between SEO vs AEO vs GEO.

• AEO (Answer Engine Optimization) focuses on earning placement in featured snippets and direct answers within search engines, a precursor to what LLMO now builds upon.
• GEO (Generative Engine Optimization) is emerging as a strategy tailored specifically for AI platforms like ChatGPT or Perplexity, where structured, factual content gets cited in natural language responses.

Together, these models create a modern visibility stack, one that demands content be optimized for blue links, rich snippets, and AI-generated summaries alike.

In conclusion, AEO, LLMO, and GEO are closely related but have different definitions. AEO focuses on optimizing for direct, concise answers in formats like featured snippets and voice search. LLMO optimizes content so that large language models (LLMs) understand and incorporate it into their generated responses. GEO is a broader strategy that leverages AI to enhance content, refine keywords, improve site structure, and generate optimized content to increase visibility and user engagement with generative AI engines. AEO and LLMO are both components of a comprehensive GEO strategy.
