The decision that matters
What do AI assistants say when buyers ask about you?
When someone asks ChatGPT, Google AI Mode or Perplexity for the best provider in your field, the answer is built from sources the AI trusts: your website, directories, reviews and articles that mention you. AI SEO, generative engine optimisation (GEO) and answer engine optimisation (AEO) are overlapping names for the same job: making sure those sources describe you clearly, accurately and often. It builds on SEO, and for complex offers it connects to B2B Lead Generation.
- Who it's for
- Businesses whose buyers research before they choose: professional services, B2B, travel, healthcare and specialist ecommerce.
- What we work on
- Crawler access, business facts, answer-ready pages, reviews and third-party mentions, across the AI platforms your buyers use.
- What we measure
- Mentions, citations and referral traffic across ChatGPT, Google AI Overviews and AI Mode, Perplexity and Copilot, tracked against a baseline.
A readable observation record
Record the context, not just the mention.
An answer, a source citation and a website visit are different observations. Keep the conditions and limitations with the result so a single check cannot become a performance claim.
Observation template / unfilledIllustrative example
A repeatable question, with an honest record
Example question“What should a B2B team check before choosing an SEO partner?”
- Capture conditions
- Record the system, date, market, language and relevant account or session conditions.
- Answer observation
- Record what was actually visible and whether the business was mentioned. Retain an approved capture where appropriate.
- Source observation
- If a citation appears, record its exact destination and the claim it supports. A mention without a linked source is a different observation.
- Referral evidence
- Review available analytics for attributable visits and meaningful actions. Missing referral data is not proof of no exposure.
- Interpretation
- Separate observed facts from possible explanations. One check does not establish stable visibility, market share or commercial impact.
- Next check
- Repeat a defined question set under documented conditions and compare carefully.
What we do
What our AI search optimisation services include.
Open the door to AI crawlers
We check that Googlebot, Bingbot and OAI-SearchBot can reach and read your key pages, and fix what blocks them. Technical SEO handles deeper issues. Search access and model-training access are separate choices, and we explain both.
OutputAn access report and the fixes, implemented or ticketed.
Make your business facts consistent
AI systems cross-check your name, services, locations, prices and reviews across your site, Google Business Profile, LinkedIn and directories. We find the conflicts and fix them, so every source tells the same story.
OutputOne accurate description of your business, everywhere it appears.
Build pages that answer buyer questions
We map the questions buyers ask AI assistants and create or improve pages that answer them directly, with real evidence, clear structure and FAQs. Content SEO supplies the page strategy.
OutputAnswer-ready pages AI systems can quote.
Earn the mentions AI relies on
AI answers lean on reviews, directories, best-of lists and articles. We help you collect reviews, get listed where it matters and earn genuine mentions from relevant publications.
OutputMore of the third-party sources AI answers trust.
Commercial scope
What does AI search optimisation cost?
AI search work is part of the Essentials SEO plan, from £1,500/month, or the Growth plan, from £2,500/month, when you want paid ads in the same plan. Prefer a fixed-price starting point? The AI Visibility Audit is £495, delivered within 10 business days and credited against your first month if you continue.
Agree the scopeWhat we agree together
Evidence you can publish
Your team verifies facts and supplies first-hand expertise. Client examples and screenshots need permission; where proof is not available, we say so rather than invent it.
Access and implementation
We need CMS, Search Console and analytics access. You retain ownership of every account. If pages cannot be changed, we deliver a prioritised handover instead.
Platforms decide
We control the work, not how AI platforms select sources or generate answers. That is why we measure mentions, citations and referrals separately and report them honestly.
Where to start
Practical questions
AI SEO and GEO questions, answered.
Sources we followGoogle: AI features and your websiteOpenAI: crawler documentation
What is generative engine optimisation (GEO)?
GEO is the work of making your business easy for AI systems like ChatGPT, Google AI Overviews and Perplexity to understand, trust and recommend. It overlaps heavily with SEO: crawlable pages, clear facts, useful content and third-party mentions.
Who is RankNexus, and where are you based?
RankNexus is the trading name of Rank Nexus LLC, a marketing agency founded in May 2022 and led by M. Zeeshan (CEO & Founder) and M. Nouman (Co-founder & Managing Director). We work with UK businesses remotely from our registered office in Denver, Colorado, with UK prices in pounds and UK spelling throughout.
How do I choose an AI search agency in the UK?
Ask how they measure AI visibility: which buyer questions they track, on which platforms and how often. Ask for their method in writing rather than a promise of guaranteed citations, which no one can honestly give. A good agency starts with a baseline you can check yourself and reports mentions, citations and referrals separately.
Do UK buyers see AI Overviews and AI Mode?
Yes. Google shows AI Overviews and AI Mode in the UK, and ChatGPT, Perplexity and Copilot are widely used here, so more UK buyers now meet a recommendation before they ever visit a website.
What does an AI SEO agency do?
An AI SEO agency makes your business easier for AI assistants to find, understand and recommend. In practice that means fixing crawler access, making your business facts consistent across the web, building pages that answer buyer questions and earning mentions on the sources AI answers rely on, then tracking how often you are named.
What's the difference between SEO, GEO and AEO?
SEO improves your visibility in search results, AEO focuses on answering questions directly, and GEO focuses on being used and cited in AI-generated answers. In practice the work overlaps heavily, so we plan it as one programme.
Is LLM SEO or ChatGPT SEO different from GEO?
No. LLM SEO, ChatGPT SEO and AI SEO are other names for the same work: helping large language models such as ChatGPT, Gemini and Perplexity find, trust and cite your business. We plan it as one programme with GEO and AEO.
How do I get my business recommended by ChatGPT?
Make sure OAI-SearchBot can reach your site, keep your business facts consistent everywhere, publish pages that answer buyer questions with real evidence, and earn reviews and mentions on sources ChatGPT trusts. There is no shortcut, but the work compounds.
Does ChatGPT use Google or Bing results?
ChatGPT search uses its own crawler, OAI-SearchBot, alongside search partners, and studies disagree on how closely its sources match Bing. We make sure you are visible in both Google and Bing, which covers most AI assistants.
Do we need an llms.txt file or special AI schema?
No. Google's guidance says you don't need new AI text files or special schema to appear in its AI features, and that llms.txt neither helps nor harms there. Structured data still helps search engines read your facts, so we use it where it matches visible content.
How do crawler controls affect the work?
OAI-SearchBot controls whether you can appear in ChatGPT search, while GPTBot is a separate crawler for model training with its own setting. Google-Extended is likewise separate from Google Search. We help you choose each setting deliberately.
How do you measure AI search visibility?
We track a fixed set of buyer questions across ChatGPT, Google AI Overviews and AI Mode, Perplexity and Copilot every month, alongside Search Console's Generative AI performance reports, Bing's AI performance data and AI referral traffic in analytics. Mentions, citations and referrals are reported separately.
How long does AI search optimisation take?
Access and fact fixes can change what AI systems read within weeks. Repeatable changes in AI answers usually take three to six months, because they depend on new content being crawled and on mentions building up.
Can a small business compete in AI search?
Yes. AI answers often cite specific, well-structured pages and niche sources over big brands. A clear, consistent business with genuinely useful answers can be recommended alongside much larger competitors.
Can you guarantee citations or mentions?
No. AI platforms choose their sources, and answers vary by question, location and time. We commit to the work and to honest measurement, and we show you exactly what changed.
Is AI search optimisation included in your SEO plans?
Yes. Essentials SEO includes the AI search basics: crawler access, consistent business facts and answer-ready pages. Deeper work like prompt tracking and mention building can be added or run as its own programme.
What does the £495 AI Visibility Audit include?
Thirty buyer questions tested across four AI platforms, up to three competitors, a map of the sources AI answers rely on, an entity and crawler check, and a prioritised 90-day action list, delivered within 10 business days with a walkthrough call.
