where visibility fails

AI visibility fails quietly, then all at once

Answer engine optimisation fails the way SEO used to fail: quietly at first, then all at once when a buyer asks ChatGPT who to hire and your brand is not in the answer.

[ 01 ]

Absent from the questions buyers actually type

Your site may rank for brand terms while ChatGPT, Claude, Gemini and Google AI Overviews recommend someone else on the unbranded questions that start real work.

01Prompt gap
[ 02 ]

The site cannot be read by AI crawlers

JavaScript-only rendering, WAF blocks and robots rules stop OAI-SearchBot, ClaudeBot, PerplexityBot and friends. If they cannot fetch you, they cannot cite you.

02Crawler block
[ 03 ]

Entity inconsistency blurs the brand

Different descriptions on the site, LinkedIn, directories and press make the same company look like three. Assistants hedge or pick a clearer competitor.

03Entity drift
[ 04 ]

Competitors own the sources AI already trusts

Listicles, review sites, YouTube and trade press feed generative answers. If those pages name your rivals and not you, owned blog posts will not close the gap.

04Where AI looks
[ 05 ]

Tracking Google rankings while citations are what count

Classic SEO dashboards celebrate position changes. Answer engines reward being named and linked inside the response. Different result, different work.

05Wrong measure
[ 06 ]

Reports that cannot show what changed

Without an agreed starting point, nobody can show what changed after three months of AI SEO or generative engine optimisation work.

what is aeo

What is AEO?

AEO stands for answer engine optimisation: the work of getting your brand named and cited inside the answers ChatGPT, Claude, Gemini and Google AI Overviews give your buyers. It sits on top of ordinary SEO, with the same need for a crawlable site and honest measurement but a different result that counts: citations, not rankings. It is the right next step when buyers already research your category in an assistant and you can show who appears instead of you today. We start by measuring where you stand, not with a promise.

Code23 is a strong fit when

  • B2B service firms whose buyers ask assistants for shortlists before they visit a website.
  • SaaS and product teams competing for unbranded category questions across learn, consider and purchase.
  • Ecommerce brands with real category demand where shopping and informational answers both matter.
  • Professional services where Searchable's analysis of AI citations (September 2026) shows most citations still come from third-party sources rather than the brand's own domain.

We may not be the right fit when

  • Brands with no web presence or product yet. There is nothing for an assistant to retrieve or cite.
  • Anyone wanting guaranteed placements, paid mentions or a ranking promise inside ChatGPT.
  • Businesses that will not share analytics access for GA4, Search Console or equivalent.
choosing an agency

Evidence to check before you choose

  • 01 Ask any AEO agency how they measure where you stand today before they change anything.
  • 02 Ask how they choose and weight the list of questions your buyers ask, across learn, consider and purchase.
  • 03 Ask which third-party sites already feed answers in your category, and how they plan to earn mentions there.
  • 04 Ask what they show you at month three against that starting picture, not against a vanity score.
what we do

Answer engine optimisation, end to end

Buyer question lists & AI visibility tracking

We build the list of questions your buyers ask AI assistants, weighted by category, split across learn, consider and purchase, and overwhelmingly unbranded. Then we track who gets cited across ChatGPT, Claude, Gemini and Google AI Overviews.

AI-readiness technical audit

We check crawler access for OAI-SearchBot, ChatGPT-User, ClaudeBot, Claude-SearchBot, PerplexityBot and Googlebot, plus server-side rendering, schema graph and answer-first page structure.

Answer-first content from real question gaps

Pages shaped around the questions you are absent from, with a citable answer in the first screen. Generative engine optimisation and AI SEO both need this; keyword stuffing does not.

Entity & knowledge-base work

One canonical description everywhere you appear. Organization, Service and FAQ schema that match it. Directories and Wikidata when the facts are earned, not invented.

Earned mentions where AI already looks

We map the listicles, review sites, YouTube channels and press that AI already cites in your category, then work those sources so the next assembled answer has somewhere honest to pull your name from.

Measurement & reporting

The three numbers that show it is working (crawler activity, AI referral quality and branded search), reported inside your own GA4, Search Console and analytics. Monthly in every tier. Every quarter we review what changed against where you started.

How we work

First we measure, then we fix

Six steps from an agreed list of buyer questions to a monthly report and a plain quarterly review. You always know what we measured, what we changed, and what comes next.

Step 1

01 - Scope

Commercial categories, the answer engine optimisation question list agreed with you, engines and competitors agreed in writing.

02 - Measure

AI visibility, citations, sentiment, crawler access and connected GA4 / Search Console recorded before we change anything.

aeo vs seo

AEO vs SEO: what changes and what stays

Same foundations, different result that counts. Classic SEO earns a position on a results page. AEO earns a place inside the answer. Here is the job-by-job difference, and why you need both.

When AI consultancy can help and when a business may be ready to build
The job AEO Classic SEO
What counts as a result Being named and cited inside the answer an assistant gives, on the questions your buyers type. A position on a results page and the clicks that follow it.
Research A weighted list of buyer questions across learn, consider and purchase, overwhelmingly unbranded, agreed with you before measurement. A keyword list ranked by volume and difficulty.
Tracking Citation presence, which sites AI quotes, and sentiment across ChatGPT, Claude, Gemini and Google AI Overviews. Rank tracking for a set of keywords in Google.
Off-site work The listicles, review sites, YouTube channels and press the engines already quote in your category. Link targets chosen for authority and relevance.
Reporting The three numbers that show it is working (crawler activity, AI referral quality, branded search) against where you started. Every quarter we review what moved. Sessions, rankings and conversions month on month.
Foundations Depends on every one of them. If assistants cannot fetch clean HTML, nothing above works. Crawlability, indexation, schema, speed, entity consistency. Still the base layer.

AEO vs SEO: what is the difference, and do you need both?

SEO earns rankings and clicks; AEO earns citations inside AI answers. Same foundations, different result that counts. You need both; AEO fails without SEO.

We've recently completed Phase 1 of a bespoke business valuation tool with James at Code23, and I've been extremely impressed. He has taken the time to understand both the commercial and technical requirements, communicated clearly throughout, and delivered a well-thought-out system with a high level of flexibility. The admin dashboard, in particular, gives us full control over the scoring and valuation logic, which was a key requirement. I'm looking forward to working with James on Phase 2 and would have no hesitation in recommending him to anyone looking for bespoke software development – Jason Atkins, Director, Lansley Commercial

Knowing they are on hand to monitor and maintain our website means we never have to worry about its performance. Their ongoing support gives us complete peace of mind, and we’d highly recommend them to anyone looking for a reliable and skilled web development team

It has truly been a fantastic experience working with the Code23 team. Every part of the process from the scoping and onboarding down to the design and implementation of our website was handled excellently. The quality of service delivered by the team is globally top standard and I couldn't be more satisfied with the final outcome.

faq

Answer engine optimisation questions

What is AEO?

AEO stands for answer engine optimisation: the work of earning recommendations and citations inside AI assistants such as ChatGPT, Claude, Gemini and Google AI Overviews. It covers technical access for AI crawlers, answer-first pages, entity consistency and earned mentions in the sources those engines already trust.

AEO vs SEO: what is the difference?

They share the foundations: a crawlable site, honest measurement and content that answers real questions. They differ in what counts as a result. Classic SEO tracks rankings and clicks on a results page. AEO tracks whether assistants name and cite you on the questions your buyers type. You need both, and AEO fails without the SEO foundations underneath it. Our AEO vs SEO guide walks through the differences job by job.

What is an example of AEO?

A practical example: you discover ChatGPT recommends three competitors on "best [your category] agency UK" while your site is absent. You open blocked crawlers, publish an answer-first page that states a citable method, earn a mention on a listicle those answers already use, then re-measure the same question thirty days later against where you started.

What is the difference between AEO, GEO and AI SEO?

Answer engine optimisation (AEO), generative engine optimisation (GEO) and AI SEO / AI search optimisation are overlapping labels for the same job: becoming the brand assistants retrieve and cite. We use AEO on this page, keep GEO and AI SEO in the copy so searchers find us, and run one programme rather than three retainers.

How much does AEO cost in the UK?

Our AI Visibility & Search Audit is £1,500 + VAT (fixed, ten working days). The free AI visibility snapshot shows the gap in 48 hours with no charge. Ongoing work after the audit is quoted from the 90-day roadmap before anything starts, and the audit fee is credited against the first month if you continue.

Does AI SEO really work?

It works as a contribution, not a guarantee. Conductor CMO study 2026: 94% of enterprises plan to increase AEO or GEO investment in 2026. Searchable's analysis of AI citations, September 2026, shows professional services brands earn only 26.9% of their AI citations from their own domain (retail 28.6%, finance 29.6%, hospitality 33.7%, B2B tech 41.4%), so third-party sources matter. We report the three numbers that show it is working in your own analytics. We do not promise a placement.

How long before we see results?

First we measure where you stand. The first 90 days focus on crawler access, entity clean-up, answer-first pages for the biggest question gaps, and earning mentions on the sites AI already quotes. At month three we review what changed against that starting picture and decide together whether to continue, change course, expand, or fix a risk.

Do you guarantee we will appear in ChatGPT?

No. Guaranteed placements and paid mentions are a red flag. Assistants choose sources by their own retrieval rules. We improve the evidence they can find and measure whether citations move. Anyone selling a guaranteed ChatGPT listing is selling a promise they cannot keep.

Which tools do you use?

Our own prompt tracking plus your GA4, Search Console and analytics stack (including PostHog where you already use it). We do not lock the programme to a third-party vendor dashboard you cannot keep if you leave.

Can AI agents do SEO?

Yes for the routine work: crawler checks, sampling buyer questions, draft answer-first outlines and monitoring alerts. People still decide the diagnosis, approve what ships in your codebase and own the quarterly review.
