What is AI SEO & LLMO And Why Do They Matter?

Search has changed.

People don’t just “Google” things anymore. They ask ChatGPT. They use Perplexity. They turn to Bing Copilot, Google Gemini, Grok, and whatever comes next. And what they get in return isn’t a traditional list of websites. It’s a direct answer. Summarised, simplified, and usually sourced from whoever the AI trusts most.

That could be you.

But only if your content is designed for these systems.

This is where AISEO and LLMO come in. And if you're not paying attention, you're already falling behind.

What is AISEO and Why Should You Care?

AISEO stands for Artificial Intelligence Search Engine Optimisation. It’s not a buzzword. It’s the reality of how content is now being discovered, consumed, and trusted online.

AISEO is the process of making your content easily understood and referenced by large language models. These models, like the ones powering ChatGPT and Perplexity, no longer rely solely on links. They generate responses based on everything they’ve learned across the internet.

When someone asks, “What’s the best UK agency for SEO and brand video?” the AI isn’t giving a list of ten sites. It might just name one or two companies. Yours should be one of them.

You’re no longer competing to rank. You’re competing to be the answer.

What is LLMO?

LLMO stands for Large Language Model Optimisation. It complements AISEO but goes deeper.

While AISEO focuses on visibility and structure, LLMO is about teaching AI systems to understand and trust your brand. It ensures your name surfaces when an AI needs a source it can stand behind.

LLMs gather information from a wide range of sources. That includes your blog posts, your YouTube transcripts, your LinkedIn and Twitter activity, Reddit threads, online publications, customer reviews, and your search engine presence.

If you're not visible across those channels, the AI simply won't recommend you. Not because your business isn’t good, but because it doesn’t know you exist.

Why Ignoring This Is a Risk

Let’s say someone types into Perplexity, “Top creative agencies for healthcare campaigns in the UK.”

If your competitor has structured their content correctly, published in the right places, and positioned their brand for AI discovery, they’ll be recommended. You won’t even know the search happened.

This isn’t about being better. It’s about being visible in a system that plays by different rules.

The good news is that visibility in AI responses is achievable. But it takes an intentional shift in how you produce, structure, and distribute your content.

What Makes Content AI-Readable?

At FatFinger, we specialise in this. We don’t guess how to make content AI-friendly. We test it. We adapt it. We optimise it for how search works today.

Here’s what works.

1. Authoritative content with depth
Write with purpose. Cover topics thoroughly. Answer the real questions your audience has. Shallow content will get ignored, by humans and AI alike.

2. Semantic relevance
It’s no longer about one keyword. AI models look for context. That includes related terms, tools, industries, and problems you solve. Think big picture.

3. Clear structure
Use headings, summaries, and short paragraphs. Make it easy to scan. If an AI can’t break down your content into digestible parts, it won’t use it.

4. Visibility across trusted platforms
Your content should live beyond your website. Post on LinkedIn. Publish on YouTube. Get mentioned on Reddit. Appear in industry articles. The more touchpoints you have, the stronger your digital reputation becomes.

5. Specificity
Don't just say you offer SEO. Say you optimise SEO for legal tech startups or produce animated campaigns for NHS partners. The more specific you are, the easier it is for AI to connect your brand to a search query.

6. Don’t abandon traditional SEO
Google and Bing still matter. The metadata, internal links, site speed, and technical health of your site all contribute to how you show up. These fundamentals support your AISEO efforts rather than replace them.

What Happens When You Get This Right?

Even if no one visits your website, your content can still deliver results.

If ChatGPT recommends you by name in an answer, you’ve already gained authority, trust, and visibility. That mention may drive a direct enquiry. It may build brand awareness. It may win you a client.

You didn’t need a click. You didn’t need an ad. You just needed to be understood by the system that was asked the question.

This is the new landscape. And it rewards brands that understand how discovery actually works in 2025.

What We Do at FatFinger

We don’t just optimise websites. We engineer visibility.

At FatFinger, we build content systems that work for today’s search environment. We create strategies that teach AI to recognise your brand, understand your expertise, and recommend you when it counts.

That might mean publishing long-form blog posts with the right entity mapping. It might mean building specific landing pages that answer niche questions. It might mean getting your work mentioned on forums, social, or YouTube.

We’ve done it for NHS trusts, law firms, tech startups, regulators, and creative industries.

We can do it for you.

Let’s Make Sure You’re Being Found

If your business isn’t showing up in AI-generated answers, your visibility is already being chipped away. But this is still early. Most of your competitors haven’t figured this out.

That gives you a window of opportunity. We can help you take advantage of it.

Let’s have a proper conversation. Just a look at what’s working, what’s not, and what you can do to get ahead.
