If SEO was the star of digital marketing for the past two decades, then Large Language Model Optimisation (LLMO) is its bold, fast-talking cousin that just moved in and is already rewriting the rules.
With tools like ChatGPT, Gemini, and Claude becoming digital sidekicks for millions of users, a question naturally arises: How do these models find, trust, and cite your website content? Enter LLMO – a growing practice that helps ensure your web pages are discoverable, relevant, and useful to AI-driven models.
At Plus Promotions, we help businesses stay ahead of digital trends. Let’s break down what LLMO is, why it matters, and how you can start adapting now.
Large Language Model Optimisation (LLMO) refers to the strategic process of making your online content more accessible, relevant, and useful for Large Language Models (LLMs) like ChatGPT, Perplexity, Gemini, and other AI search assistants.
While traditional SEO is about optimising for Google’s algorithm to appear in search engine result pages (SERPs), LLMO is about optimising for AI-generated answers. It focuses more on contextual relevance, structured information, factual credibility, and citations.
Why does this matter? Because users are increasingly bypassing traditional search engines. They’re asking LLMs questions like:
And guess what? If your content isn’t in the LLM’s training data or memory, your brand doesn’t get mentioned—at all.
While LLMO and SEO aim for the same outcome—visibility—they do so using different playbooks.
Traditional SEO focuses on ranking high on Google’s results pages by targeting keywords, earning backlinks, writing strong meta tags, and optimising technical aspects like site speed. It’s a system built on user clicks and search queries.
LLMO, however, is all about being discoverable in a conversation-based ecosystem. Instead of trying to win a top position on a search engine results page, you want your content to show up in an AI-generated response. That means your site needs to be structured in a way that is not only clear and factual, but also semantically rich and contextually helpful.
Think of it this way: SEO helps you get found by Google. LLMO helps you get mentioned by AI. It’s not about ditching one for the other—it’s about enhancing your strategy for a new type of digital assistant.
Unlike Google’s bots that constantly crawl and index websites, LLMs often rely on training datasets, embedded web indexes, and partnerships with trusted sources (like Wikipedia, news outlets, or high-authority blogs). However, many newer AI models now access live web data through tools like Bing Search API, site scrapers, and browser plugins.
Here’s what increases your chance of being “seen”:
In short: clarity + credibility = visibility.
Whether you’re a web development agency in Dublin, a solar solutions provider in Cork, or a furniture brand in Limerick, your customers are already using AI to research, compare, and make decisions.
If your business isn’t appearing in LLM outputs, your competitors will. Simple as that.
Here’s how to start optimising your content for AI models right now:
1. Write for Humans, Format for Machines
Keep your tone natural and helpful—but use H1s, H2s, lists, and bullet points. Structure matters more than ever.
2. Add Author Bylines & Source Credibility
LLMs prefer citing pages with clear authorship, transparent sourcing, and trustworthy domains. No shady stuff.
3. Keep Content Factual and Concise
AI models love facts and summaries. Use stats, dates, prices, and definitions where relevant.
4. Update Existing Blogs with Semantic Richness
Don’t just chase new content—improve what you already have. Add FAQs, internal links, and schema markup to existing posts.
5. Be the Source, Not the Echo
Instead of repeating what others say, share expert insights, original research, or client case studies. LLMs reward novelty and authority.
Google’s Search Generative Experience (SGE) and OpenAI’s collaboration with Perplexity are early signs of what’s to come: AI-powered search will soon dominate the discovery funnel.
We expect to see:
