What Has Changed

LLM SEO vs Traditional SEO: why ranking alone is no longer enough.

When a potential customer searches for what you do, Google now generates an AI answer at the top of the results page before a single link is shown. That answer cites specific sources, names specific businesses and shapes decisions before the user clicks on anything.

The question driving competitive advantage right now is this: when AI generates an answer in your sector, is your business the source it cites?

Traditional SEO

Optimises pages to rank in blue link results. Measures position, clicks and traffic. A strong position can still mean complete invisibility in AI-generated answers where no click ever happens.

LLM SEO

Optimises your digital presence so large language models cite you as the authoritative source. Measures Citation Share: how frequently your business is cited as the trusted source in AI-generated answers. A fundamentally different commercial outcome.

Citation Share is the metric that captures your AI search visibility.

How often your business is named as the trusted source in AI-generated answers for the queries that matter commercially. Most businesses have a Citation Share of zero for their most important terms and have no idea.

The quick test

Open an incognito browser, not logged into any Google account. Search the three most commercially important queries in your sector. If an AI summary panel appears above the ranked results and your business is not cited in it, your Citation Share for those queries is currently zero. That is the gap this service is designed to close.

The Gap Nobody Is Talking About

Why most businesses are invisible in AI search, and what the gap is actually costing you.

This is not a criticism of any individual agency. The shift to AI-generated answers has happened faster than most practitioners anticipated and the metrics, methodologies and measurement frameworks required are genuinely new. But the commercial consequence for your business is real regardless of the reason.

There are three reasons most businesses are invisible in AI search that go unaddressed in a standard engagement. Your entity is not verified in the data layer that determines citation authority. Your content is structured for human readers rather than machine extraction. And nobody is measuring the metric that shows whether any of this is working.

None of these are content volume problems. Most businesses already have enough content. What they lack is the architecture, the verified connections and the measurement framework that turns existing authority into AI search visibility.

For a deeper understanding of how our approach connects traditional and AI search performance, our SEO consulting service covers the full strategic picture.

Ask your current agency what your Citation Share is. If they cannot answer that question or do not know what it means, you have your answer about whether your AI search visibility is being actively managed.

Our Methodology

Our LLM SEO and GEO methodology: what we actually do.

The methodology that put our clients above TripAdvisor, Saga Holidays and Lonely Planet in AI search, and our own content above Search Engine Land for targeted ecommerce SEO keyphrases. Applied to every engagement from day one.

Entity Verification Audit

We map your current position in the data layer Google uses to determine who gets cited. Every missing connection between your website, credentials and third-party references is identified and closed through Schema.org markup.

Content Structured for Machine Extraction

We audit and restructure your key pages so AI systems can extract direct answers. Semantic HTML5 architecture, question-led headings, direct answer statements at the opening of every section. It is the same answer-first approach behind our work as an AEO agency in London.

Citation Share Tracking

We introduce Citation Share as a primary performance metric from month one. Monthly tracking of how often your brand is named as the authoritative source in AI-generated answers for your target queries. Most businesses we work with start at a Citation Share of zero for their most commercially important queries. Within three to six months that number moves measurably.

Content Built to Be Cited

Pages, articles and guides researched and structured specifically for AI citation rather than traditional ranking. Direct answers in opening sentences, question-phrased headings and self-contained answer sections that AI can extract and cite without surrounding context.

Social and Third-Party Authority

Google cross-references entity data with LinkedIn presence, reviews and brand mentions. We ensure your off-site presence feeds the trust signals that inform citation authority across AI platforms.

Plain Language Reporting

Citation Share, traditional rankings and traffic quality reported in plain English every month. What happened, why it matters, what we are doing next. No jargon. No vanity metrics.

The methodology behind these results is not publicly documented.

Every result we show you was produced using the same structural approach. We do not publish it. We apply it. If you want to understand what it would look like applied to your business, that conversation starts here.

Verifiable Results

Not claims. Results. Check them yourself.

Every result below was produced using the methodology described above. All are live and verifiable at time of publication.

It is a trust and conversion advantage.

Who This Is For

This conversation is worth having if any of these apply.

Strong credentials, invisible in AI search

Your business has a verifiable track record and strong credentials, but you have no idea whether AI is citing you or a competitor when customers search for what you do.

Your agency has never mentioned Citation Share

Your current agency reports on rankings and traffic but has never mentioned Citation Share, entity verification or how your content performs in AI-generated answers. That gap is costing you enquiries every month.

You need to demonstrate commercial ROI

You are a marketing director or business owner who needs to demonstrate that digital spend is building genuine competitive advantage rather than maintaining a position AI search is already bypassing.

You operate in a competitive sector

You operate in a sector where being the cited source in AI-generated answers would give you a meaningful and compounding commercial advantage over competitors who have not yet acted.

You want to act before your competitors do

You understand that the window to establish citation authority ahead of your competitors is open right now. The businesses acting on this now are building a position that compounds. The ones waiting will find the ground already taken.

You work in legal, travel or ecommerce

We work across legal, travel, hospitality and ecommerce. Our results have been achieved in competitive markets against globally recognised publishers. We deploy dedicated GEO programmes for travel brands and tour operators, and offer a specialist Travel SEO service built around AI search visibility for the sector. For law firms, we offer a dedicated Legal AI SEO service built around specific institutional authority requirements.

Common Questions

What clients ask us before we start.

What is LLM SEO and how is it different from traditional SEO?
Large language model SEO optimises your digital presence so that AI systems cite your business as the authoritative source when generating answers. Traditional SEO focuses on ranking position in blue link results. The difference is commercially significant. A business can hold strong traditional rankings and be completely absent from AI-generated answers if its entity connections, content structure and off-site authority signals have not been built for machine citation. These are two separate optimisation disciplines with different methodologies and different metrics.
What is Citation Share and why should I be measuring it?
Citation Share is the proportion of AI-generated answers in your target query set where your business is named as the source, measured over a defined reporting period. It is the most commercially relevant measure of AI search performance and the one most businesses have never seen on an agency report. As Google AI Overviews capture a growing proportion of search intent before users click anything, Citation Share increasingly determines whether that intent reaches your business or a competitor.
What is entity verification and how does it affect AI search visibility?
Entity verification is the process of connecting your online presence across multiple authoritative data sources so Google can confirm who you are, what you do and why you should be trusted. This means linking your website to your LinkedIn company page, industry body memberships, published articles, third-party reviews and any other institutional credentials through Schema.org markup. Without these verified connections, earned credibility remains invisible to Google's AI systems.
How is Digitalhound different from other agencies offering AI search services?
We lead with verifiable proof rather than methodology descriptions. Our own content ranks above Search Engine Land for specific ecommerce SEO keyphrases without link building. A client's travel content ranks above TripAdvisor, Saga Holidays and Lonely Planet with Google's AI Overview citing it directly. GetCarHire.com recorded 32,400 Bing AI citations over three months from zero. All results are live and verifiable. They were produced by the same methodology we bring to every engagement.
Which sectors do you work in?
We work across legal, travel, hospitality and ecommerce. Our results have been achieved in competitive markets against globally recognised publishers. Informational and research queries in these sectors trigger AI-generated answers most frequently, which means Citation Share is already the primary visibility battleground rather than ranking position. For law firms, where institutional credentials create specific AI search challenges, we offer a dedicated AI search service for law firms.
What is Generative Engine Optimisation (GEO) and is it the same as LLM SEO?
Generative Engine Optimisation, or GEO, is the practice of optimising your content and digital presence so it appears as a cited source in AI-generated answers from platforms including Google AI Overviews, Bing Copilot, Perplexity and ChatGPT. LLM SEO is the broader discipline of which GEO is a component: LLM SEO covers entity verification, structured data, content architecture and off-site authority signals, while GEO focuses specifically on the content formats and answer structures that AI generative engines extract and surface. At Digitalhound we treat them as a single integrated practice. Optimising for one without the other leaves gaps in your AI search visibility.
How quickly will we see movement?
Entity verification improvements begin to influence AI search visibility within weeks as Google recrawls updated schema markup. Content restructured for machine extraction typically shows Citation Share movement within one to three months depending on sector competitiveness. These are illustrative timelines based on our experience, not guaranteed outcomes. We track Citation Share from the first month of every engagement so you have a baseline and a trajectory rather than a promise.
