AEO Pricing UK: What AI Search Optimisation Should Actually Include

For planning, allow £750–£2,500 for a focused UK AI-visibility audit, £1,000–£3,000 a month for integrated SEO and AEO work, and £3,000–£8,000+ for a larger catalogue, brand or multi-market programme.

These are planning bands, not market averages. The price should follow the number of entities, products, pages, competitors, answer engines and implementation tasks—not the novelty of the acronym.

AEO should not be a mysterious second retainer bolted onto ordinary SEO. Google says its established SEO foundations remain relevant to AI Overviews and AI Mode and that no special AI schema or machine-readable file is required. Additional spend is justified when it funds additional research, content, technical work, authority building and measurement.

AEO costs at a glance

The baseline check tells you what is visible. The audit explains why and what to do. The monthly programme implements and learns. Do not pay programme money for repeated screenshots of prompts.

What AEO means in practical work

Answer engine optimisation improves the chance that a business and its evidence are correctly discovered, understood and cited in AI-assisted search and answer experiences.

The work overlaps strongly with sound SEO:

• accessible crawling and indexable pages;
• clear service, product and entity information;
• content that answers real questions with evidence;
• useful internal links and information architecture;
• structured data that matches visible content;
• consistent business facts across owned and trusted external sources;
• original proof, expertise and references worth citing;
• measurement of search discovery and commercial action.

The additional layer is systematic testing across AI surfaces, prompt patterns and citation sources. That needs care because answers vary by wording, location, model, account context and time.

Our SEO-to-AEO guide explains the discipline. The pricing rule is simple: overlap should reduce duplication, not create two invoices for the same technical fix.

What Google and OpenAI currently say

Google's AI features guidance states:

• ordinary SEO best practices remain relevant;
• a page must be indexed and eligible for a search snippet to appear as a supporting link;
• there are no extra technical requirements for AI Overviews or AI Mode;
• no special schema or AI text file is required;
• crawling, internal links, page experience, text content and matching structured data still matter;
• AI-feature traffic is included in Search Console's Web search reporting rather than separated into a dedicated filter.

OpenAI's publisher guidance says public sites can appear in ChatGPT search and advises publishers not to block OAI-SearchBot if they want content included in summaries and snippets. Referral traffic can be measured in analytics, subject to consent and attribution limits.

Neither source promises inclusion. Eligibility is not selection.

What a £750–£2,500 AEO audit should include

1. Business and entity baseline

The audit should confirm the exact company, brands, services, products, people, locations and differentiators that answer systems need to distinguish. It should find conflicting names, descriptions, addresses or relationships.

2. Technical access

Check indexability, canonicals, rendering, robots controls, OAI-SearchBot policy, internal links, structured data and whether important evidence exists in accessible text.

3. Prompt and answer sample

Use a documented set of prompts across named engines and modes:

• category discovery;
• problem-led questions;
• comparisons;
• local or regional selection;
• brand facts;
• price and suitability questions;
• follow-up questions that narrow the choice.

Record date, engine, wording, answer, brands mentioned and cited sources. The sample must be reproducible enough to revisit, while acknowledging output variability.

4. Source and citation analysis

Identify which pages and third-party sources answer engines use for the category. Separate sources the business controls, can influence and cannot reasonably change.

5. Content and proof gaps

Map missing commercial answers, comparisons, definitions, evidence, expert authorship, policies, case studies, product facts and original data. Do not recommend 50 articles when five service pages lack basic clarity.

6. Prioritised action plan

Every recommendation needs expected value, effort, owner and dependency. The audit should end with a 30-, 60- and 90-day sequence, not an “AI readiness score” with no operating plan.

What £1,000–£3,000 a month should buy

A credible integrated programme usually combines four streams.

Technical and entity repair

Resolve access, duplicate or conflicting information, structured data, author and organisation relationships, internal linking and measurement foundations.

Commercial content

Improve the pages closest to buyer intent: costs, comparisons, suitability, process, evidence and objections. Create new pages only where the site lacks a clear owner for the question.

Authority and corroboration

Earn credible references through useful research, expert contribution, partnerships, industry profiles, digital PR and accurate third-party listings. A business cannot declare itself authoritative through schema.

Measurement and iteration

Repeat a controlled prompt sample, review Search Console and referral data, inspect citations and track qualified actions. Update the plan when the evidence changes.

At this budget, expect choices. A small team cannot research every prompt, rebuild the website, produce original studies and run national PR simultaneously.

What £3,000–£8,000+ should add

Higher spend should buy complexity or pace:

• several products, brands, countries or languages;
• larger prompt and competitor sets;
• dedicated technical and content implementation;
• original datasets, tools, benchmarks or expert research;
• digital PR and source development;
• regular stakeholder workshops and governance;
• deeper brand, product-feed or merchant integration;
• monitoring that distinguishes material change from answer volatility.

If the additional money only adds more tracked prompts and a larger dashboard, the programme has confused observation with optimisation.

AEO deliverables worth paying for

What should not be sold as a special AEO service

• adding generic FAQ sections to every page;
• installing llms.txt and declaring the site AI-ready;
• adding schema that does not match visible content;
• generating hundreds of near-duplicate articles;
• repeating brand prompts manually with no controlled method;
• buying low-quality links or mentions;
• promising inclusion in ChatGPT, Gemini, Perplexity or Google AI features;
• reporting a proprietary score without raw observations;
• renaming ordinary title and heading edits as a new technical discipline.

Some of these tasks may be useful in context. None is a complete strategy.

How to measure AEO without inventing certainty

Use four layers.

Eligibility

Can relevant systems crawl, index and understand the important pages? Are facts consistent and the visible content usable?

Sampled visibility

Across a fixed, dated prompt set, how often is the brand accurately mentioned, in which position or role, and which sources are cited? Treat this as a sample, not a census of every possible answer.

Search and referral evidence

Use Search Console for Google Web search trends, because Google does not currently separate AI-feature traffic in its reports. Track identifiable referrals from ChatGPT, Perplexity and other sources in analytics, understanding that consent and unattributed journeys create gaps.

Commercial action

Track qualified enquiries, sales, assisted conversions, branded demand and the questions sales teams hear. Visibility without a suitable offer and next step is not a return.

Do not combine the four layers into one magic number. The uncertainty is part of the measurement.

A simple buying decision

Choose a one-off audit when:

• the business wants a defensible baseline;
• the existing SEO team can implement the work;
• leaders are testing whether the channel deserves budget;
• a vendor is proposing a large retainer without evidence.

Choose an integrated monthly programme when:

• technical, content and authority work all need ownership;
• the site already has meaningful search demand or commercial proof;
• subject experts can participate;
• someone will act on the findings each month;
• SEO and AEO can share research and implementation.

Do nothing yet when the website does not clearly state what the business sells, who it serves or why it is credible. Fix the source before monitoring the answer.

Questions to ask an AEO agency

1. Which engines, modes and locations will you test?
2. How do you control prompt wording and answer variability?
3. Which work overlaps with our existing SEO scope?
4. Show the raw observations behind your visibility score.
5. What will you implement in the first 30, 60 and 90 days?
6. Which claims about AI inclusion can you not guarantee?
7. How will you measure Google AI visibility when Search Console groups it into Web search?
8. Which external sources appear in our category, and why?
9. What expertise and evidence do you need from us?
10. What do we own when the engagement ends?

The best answer may be “we cannot know that from available data”. Precision about limits is a quality signal.

Frequently asked questions

How much does AEO cost in the UK?

A useful audit may cost £750–£2,500. Use £1,000–£3,000 as a planning band for integrated monthly SEO and AEO, with larger or multi-market programmes above £3,000. Scope and implementation decide the figure.

Is AEO different from SEO?

It adds systematic attention to AI answers, entities and citations, but shares crawling, content, internal linking, structured data and authority foundations with SEO. Buy the incremental work, not a duplicated retainer.

Can an agency guarantee ChatGPT citations?

No. Answer systems choose sources dynamically and outputs vary. An agency can improve eligibility, clarity, evidence and authority and can measure a controlled sample. It cannot promise inclusion.

Do I need llms.txt for AEO?

Google explicitly says no special AI text file is required for its AI features. An llms.txt file may serve other experimental or documentation purposes, but it is not a substitute for crawlable, useful pages.

How long does AEO take?

Technical fixes may be visible after recrawling. Content and authority work can take months. Set 30-, 60- and 90-day implementation milestones, then judge trends over a longer window appropriate to the market.

Pay for evidence and implementation

AEO deserves budget when it makes the business easier to discover, understand and corroborate across the places buyers now ask questions. It does not deserve a surcharge merely because the report contains screenshots from an AI tool.
