An SEO agency offers AEO services by adding AI visibility work to what it already does. That means checking how AI assistants like ChatGPT, Gemini and Perplexity describe each client, fixing the content, schema and entity gaps behind weak answers, and tracking citations every month. Most agencies start by selling it as an add-on to SEO retainers.
This guide covers the whole picture. You will learn what AEO is, how it differs from SEO, which skills and tools you need, what to put in a package, how to price it, and how to roll it out on client sites without hurting your margins.
The short version:
- AEO builds on SEO. It does not replace it.
- Start every client with an AI visibility audit. The findings sell the service for you.
- Package AEO as monthly work: prompt tracking, answer-first content, schema, entity building and off-site citations.
- Price by prompts, engines and competitors tracked, not by keywords.
- Report mentions, citations, accuracy and share of voice, not just rankings.
- Never promise a client they will “rank #1 in ChatGPT”. Promise a process and a measurable trend.

What is AEO and how is it different from traditional SEO?
AEO stands for answer engine optimization. It is the work of making a brand the source that AI assistants use, mention and cite when they answer questions. The main answer engines today are ChatGPT, Google Gemini, Google AI Overviews and AI Mode, Perplexity, Claude and Microsoft Copilot.
You will also hear the term GEO, short for generative engine optimization. In practice, most people use AEO and GEO to mean the same thing: getting a brand into AI-generated answers.
Traditional SEO aims to rank a page in a list of links. Success is a high position and a click. AEO aims to get the brand included inside the answer itself. Success is a mention, a citation link and an accurate description. Often the user never clicks at all, so being named is the win.
| Traditional SEO | AEO | |
|---|---|---|
| Main goal | Rank a page in search results | Get the brand mentioned and cited in AI answers |
| What you measure | Rankings, clicks, organic traffic | Mentions, citations, accuracy, share of voice |
| Where it shows | Blue links on a results page | Inside a written answer from an AI assistant |
| Typical query | Short keywords, like “SEO agency London” | Full questions, like “Which SEO agency in London is best for law firms?” |
| How results behave | Fairly stable positions | Answers change from one run to the next |
| Key signals | Links, relevance, page experience | Clear answers, entity consistency, trusted third-party mentions |
How does AEO differ from traditional SEO day to day?
The fundamentals overlap, but the daily work shifts in five ways.
- Questions replace keywords. People type or speak full questions to AI assistants. Your research starts with prompts, not keyword lists.
- One question becomes many. AI engines split a big question into smaller sub-questions, a process called query fan-out. A page that answers only the headline question often loses to a page that answers the follow-ups too.
- Answers blend sources. An AI answer can pull facts from five or ten pages. You compete to be one of those sources, not to be the only result.
- Brand facts must match everywhere. If your client’s website, Google Business Profile, directories and review sites disagree, AI engines get confused and may repeat the wrong version.
- You measure samples, not positions. The same prompt can produce a different answer tomorrow. So you track a set of prompts many times and watch the trend.
Does AEO build on SEO or replace it?
AEO builds on SEO. It does not replace it.
Most AI assistants that search the web still need to find, crawl and trust your client’s pages. Google AI Overviews draw on pages in Google’s index. Other assistants run their own searches or use partner search indexes. If a site is slow, blocked, badly structured or has no authority, it is less likely to be picked as a source.
What changes is the emphasis. SEO asks, “Can this page rank?” AEO adds three more questions:
- Can an AI engine lift a clear, correct answer from this page in a few seconds?
- Does the web agree on who this brand is and what it does?
- Do trusted third-party sources mention this brand when they discuss the topic?
A simple way to explain it to clients: SEO gets you into the library. AEO gets you quoted in the answer.
What are AEO services and why are they important for SEO agencies?
AEO services are the paid deliverables an agency provides to improve how a client appears in AI answers. A typical set includes an AI visibility audit, prompt tracking across several engines, answer-first content, structured data and entity work, off-site citation building, hallucination checks and monthly reporting.
For SEO agencies, AEO matters for four practical reasons.
- Clients are already asking. Business owners test ChatGPT for their own brand. When a competitor shows up and they don’t, they call their agency. You want an answer ready.
- It protects your retainers. If a client’s informational traffic drops because AI answers the question on the results page, a rankings-only report makes your work look weaker. AI visibility reporting shows the full picture.
- It is new revenue from existing clients. Selling a new service to a happy client is far easier than winning a new client.
- You already have most of the skills. Technical SEO, schema, content and link building all carry over. The gap is mainly prompt research, AI tracking and reporting.
What are the benefits of AEO services for clients?
Clients do not buy AEO because it is new. They buy it for business outcomes. These are the ones worth explaining in a sales call.
- They show up where buyers now ask questions. Many buyers ask an AI assistant for a shortlist before they visit any website. If the client is not in that shortlist, they may never be considered.
- Wrong answers get caught and fixed. AI assistants sometimes state old prices, closed locations or services a business never offered. AEO work finds these errors and fixes the sources behind them.
- Visitors arrive better informed. Someone who clicks through from an AI answer has usually read a summary of the business already. They often arrive further along in their decision.
- Recommendations build trust. Being named as a suggested option by an AI assistant works like a referral. It carries weight with buyers.
- They see what competitors are doing. Tracking shows which competitors get named for each question and which sources the AI trusts. That turns into a clear to-do list.
- The website gets better for humans too. Clear answers, tidy structure and FAQ sections also help readers and can improve conversion.
If a client asks why a rival keeps appearing and they don’t, this explainer on why your competitors appear in ChatGPT but your brand doesn’t is a useful read to share.
What skills are needed for an SEO agency to provide AEO services?
You do not need to hire a new team. Most AEO work fits skills your SEO team already has. Here is what to check.
1. Technical SEO
Your team needs to confirm that AI crawlers can reach the site, that important content is in the HTML rather than hidden behind JavaScript, and that firewalls or CDN bot settings are not blocking AI search bots by accident.
2. Structured data and entity SEO
This means writing clean JSON-LD for Organization, LocalBusiness, Product, Service, Person and FAQPage. It also means linking the brand to its official profiles with sameAs, and keeping the brand’s facts consistent across the web so AI engines understand who the business is.
3. Question-led content strategy
Writers need to lead with the answer. Each key page should answer its main question in the first few sentences, then cover the follow-up questions a buyer would ask next. Planning content around query fan-out is the core skill here.
4. Digital PR and off-site work
AI engines trust what others say about a brand. Getting clients into industry directories, review sites, comparison articles, podcasts and relevant community threads is now part of AEO, not just link building.
5. Prompt research and testing
Someone on the team should own the prompt set for each client. That means choosing the real questions buyers ask, running them across engines, and noting who gets named and why.
6. Data and reporting
AI answers vary, so reporting needs a basic grasp of sampling and trends. Your analyst should be comfortable with share of voice, mention rate and citation rate, and able to explain them in plain language.
7. Client education
Account managers must set honest expectations. AEO is a process of raising the odds of being mentioned. It is not a guaranteed placement. Clear communication prevents unhappy clients later.
What services should an SEO agency include in an AEO package?
A good AEO package mixes a one-time setup with ongoing monthly work. These are the core services to include.
- AI visibility audit. A baseline of how the client appears across engines for a set of real buyer questions. Include mention rate, citations, accuracy and which competitors show up.
- Prompt set research. A list of 20 to 100 questions, grouped by buyer stage, that the client wants to be part of.
- Ongoing AI tracking. Weekly or monthly runs of the prompt set across the engines that matter to the client.
- Technical AI readiness. Crawler access checks, robots.txt review, rendering checks, sitemaps and Bing Webmaster Tools setup.
- Entity and schema work. Organization and service schema, sameAs links, consistent business details, a strong About page and author profiles.
- Answer-first content. New pages that close sub-topic gaps, plus rewrites of key pages so answers are easy to extract.
- Off-site citation building. Reviews, directory listings, expert quotes and placements on the sources AI engines already cite for the topic.
- Hallucination monitoring. Catching wrong facts in AI answers and fixing the sources that cause them.
- Competitor share of voice. Who gets named most for each question, and what those competitors do differently.
- Monthly report and action plan. What changed, what was done, and the next priority tasks.
Most agencies group these into tiers. Here is a simple structure you can adapt.
| Tier | Best for | What is included |
|---|---|---|
| Starter | Local businesses and small clients | Audit, 20 to 30 tracked prompts, 2 to 3 engines, schema and entity cleanup, monthly report |
| Growth | Established SMBs and B2B firms | Everything in Starter, 50 or more prompts, all major engines, 2 to 4 answer-first pages a month, competitor share of voice |
| Authority | Competitive categories | Everything in Growth, off-site citation building, hallucination monitoring, digital PR, quarterly strategy review |
What is the difference between SEO deliverables and AEO deliverables?
Many AEO deliverables are upgraded versions of SEO deliverables you already produce. Naming them clearly helps clients see what they are paying for.
| SEO deliverable | AEO deliverable |
|---|---|
| Keyword research | Prompt research and a query fan-out map |
| Rank tracking report | AI mention, citation and share of voice report |
| On-page optimization | Answer-first rewrites with clear, extractable sections |
| Technical audit | AI crawler access and rendering check |
| Schema for rich results | Schema for entity clarity and brand facts |
| Link building | Citation building on sources AI engines already trust |
| Content calendar | Gap-driven content plan based on sub-topic coverage |
| Traffic report | AI referral traffic plus a brand accuracy log |
The biggest difference is the report. An SEO report shows where pages rank. An AEO report shows what AI engines say about the brand, how often they say it, whether it is correct, and which sources they rely on.
How do agencies implement AEO on client websites?
Here is a seven-step process that works for most client sites. It follows the order that removes blockers first and then builds visibility.
Step 1: Run a baseline audit
Pick 20 to 50 real questions buyers ask. Run them across the main engines. Record whether the client is mentioned, whether they are cited with a link, whether the facts are correct, and which competitors appear. This baseline is your before picture.
Step 2: Fix crawler access
Check robots.txt and firewall rules. AI search and retrieval bots such as OAI-SearchBot, ChatGPT-User and PerplexityBot need access if the client wants to appear in those answers. Training crawlers, such as GPTBot and ClaudeBot, and controls like Google-Extended are a separate decision. Talk it through with the client. Also check CDN bot protection, which sometimes blocks these bots without anyone noticing.
Step 3: Make the entity clear
Add Organization or LocalBusiness schema with the official name, logo, contact details and sameAs links to real profiles. Make sure the business description, services and locations match across the website, Google Business Profile, LinkedIn and key directories. Give authors proper bio pages that show real experience.
Step 4: Map query fan-out and close the gaps
For each priority question, list the sub-questions an AI engine is likely to explore. Check which ones the site already answers. Build new sections or pages for the gaps. This one step often produces the biggest gains, because most sites answer the headline question and skip the follow-ups.
Step 5: Rewrite key pages for extraction
Put a direct answer in the first 40 to 60 words under a clear heading. Use question-style H2s, short paragraphs, lists and tables. Add FAQ sections with FAQPage schema. Google now shows FAQ rich results only for a small set of sites, but the markup still helps machines read the page structure.
Step 6: Build off-site evidence
Get the client listed and reviewed on the platforms that AI engines cite for their category. Pitch expert quotes, comparison articles and podcast appearances. Take part in relevant community threads where it is genuine and useful. AI engines lean heavily on what third parties say.
Step 7: Track, report and repeat
Re-run the prompt set weekly or monthly. Compare against the baseline. Turn the gaps into next month’s action plan. AEO is steady work, not a one-off project.
A note for WordPress sites: SEO plugins such as Yoast and Rank Math already output some schema. Before adding custom JSON-LD, check the page source so you do not create duplicate or conflicting Organization markup.
What tools and software can help agencies deliver AEO services effectively?
You will need a mix of AI visibility tracking and the SEO tools you already use.
AI visibility trackers
These run your prompt sets across AI engines and record mentions, citations and competitors. Options include SiteSignal, Peec AI, Otterly.AI, Profound and Rankscale. Several large SEO suites also now offer AI visibility modules. When you compare tools, check:
- Which engines are covered, including Google AI Overviews.
- How many prompts and domains you get for the price.
- Whether each client gets separate projects and reports.
- Whether it flags inaccurate answers, not just mentions.
- Whether it tells you what to do next, or only shows data.
- Whether you can bring your own API keys (BYOK) to control costs.
We built SiteSignal for agencies in this position. It tracks brand citations across ChatGPT, Gemini, Perplexity, Claude and Google AI Overviews, and it gives each client project its own weekly action plan. It also covers technical SEO, uptime and basic security checks in the same dashboard.
Search and crawl tools
Google Search Console and Bing Webmaster Tools remain essential. Several AI assistants draw on search indexes, so indexing problems become AEO problems. A crawler such as Screaming Frog or Sitebulb helps you check rendering, headings and schema at scale.
Schema and entity tools
Use the Schema.org validator and Google’s Rich Results Test to check markup. Wikidata is worth checking for larger brands that meet its notability rules.
Analytics
In GA4, create a custom channel group for AI referrals. Include sources such as chatgpt.com, perplexity.ai, gemini.google.com, copilot.microsoft.com and claude.ai. Keep in mind that some AI traffic arrives without a referrer and shows up as direct.
Manual checks
Manual testing in a logged-out browser is useful for spot checks and screenshots. It does not scale, and a single run tells you little because answers change. Use it to support your tracking data, not to replace it.
What pricing models can SEO agencies use for AEO services?
There is no single standard yet. These six models are the most common, and many agencies combine two or three.
1. Paid audit
A one-time AI visibility audit is the easiest way in. It shows the client real answers about their brand, including competitors and errors. Many agencies credit the audit fee against the first month of a retainer.
2. Add-on to an SEO retainer
A fixed monthly fee on top of existing SEO work. This is the fastest way to start, because the client already trusts you.
3. Standalone AEO retainer
A separate monthly package for clients who want AEO on its own, or whose SEO is handled in-house.
4. Tiered pricing by scope
Price by the number of prompts tracked, engines covered, competitors monitored and content pieces delivered each month. This ties the fee to real workload and tool costs.
5. Project sprints
Fixed-price projects for defined work, such as a schema and entity cleanup or a batch of ten answer-first pages.
6. Performance bonuses, with care
Some agencies add a bonus linked to results. If you do, tie it to a trend, such as share of voice across a fixed prompt set over three months. Never tie it to a single placement, because AI answers change from run to run.
Watch your margins
Tool costs usually scale with domains and prompts, so build them into your price per client. For example, SiteSignal’s Agency BYOK plan starts at $399 a month for three domains, with extra domains at $89 each, plus your own AI API usage. On ten clients, that is about $1,022 a month in platform fees before API costs. Check current pricing before you quote, and make sure each client tier covers its tool cost plus team time.
What challenges do agencies face when implementing AEO services for clients?
AEO is still young, so expect some friction. Here are the common problems and how to handle each one.
- Answers change every time. The same prompt can give different results an hour later. Handle it by tracking a fixed prompt set many times and reporting trends, not single screenshots.
- Attribution is hard. There is no full “AI Search Console” for most engines, and some AI visits show up as direct traffic. Combine mention tracking, AI referral data and lead-source questions on forms.
- Clients expect instant wins. On-site fixes can show up within weeks in engines that search the web live. Off-site authority takes months. Set a 90-day review from day one.
- You cannot edit the AI. When an assistant states something wrong, you fix the sources it relies on: the website, profiles, directories and third-party pages. Then re-check.
- Scope creep. Clients will ask you to “just check” more questions. Put the prompt count and engines in the contract.
- Tool costs add up. Tracking many prompts across many engines costs money. Price by scope and review usage monthly.
- Skill gaps. Prompt research and AI reporting are new to many teams. Make one person the AEO lead and document your process.
- Crawler decisions. Some clients, especially publishers, worry about AI companies using their content. Explain the difference between search bots and training bots so they can make an informed choice.
What industries benefit most from AEO services offered by SEO agencies?
AEO helps most where buyers ask comparison questions before they buy, and where wrong information is costly. These industries stand out.
- B2B SaaS and software. Buyers ask “What is the best tool for…” and AI assistants answer with shortlists.
- Professional services. Law firms, accountants and consultants are often recommended by name for specific needs and locations.
- Healthcare, wellness and clinics. Accuracy matters a great deal. Wrong details about treatments, hours or locations damage trust fast.
- Local and home services. Plumbers, dentists and contractors get named in “near me” style questions.
- Travel and hospitality. Travellers ask AI assistants to plan trips and suggest hotels, retreats and tours.
- E-commerce with considered purchases. Electronics, furniture and specialist gear, where buyers research and compare first.
- Education and training. Course providers, universities and bootcamps compared on fit, price and outcomes.
- Financial services. Insurance, lending and advisory firms, where trust signals and accurate facts matter.
Can you provide case studies of agencies successfully offering AEO services?
Honest answer: AEO is new, and well-documented public case studies with clean before and after data are still rare. Be careful with bold claims you find online. Ask how many prompts were tracked, on which engines, over what period, and how often each prompt was run.
To show what a good rollout looks like, here is a worked example. It is an illustrative scenario, not a report of real client results.
A small agency serves a group of local law firms. It runs a 40-question audit across four engines for one firm. The firm is named in only a handful of answers. Two competitors dominate. One engine also lists an office the firm closed years ago.
Over the next quarter, the agency does four things. It fixes the old address across directories and profiles. It adds LocalBusiness and Attorney schema with sameAs links. It publishes answer-first pages for the sub-questions buyers ask, such as fees, timelines and what to bring to a first meeting. And it earns listings on two legal directories the engines already cite.
It re-runs the same 40 questions every week and reports the trend: mention rate, citation rate, accuracy and share of voice against the two competitors. The client sees progress in numbers they understand, and the wrong address stops appearing.
When you write your own case study, include these details so readers and AI engines can trust it:
- The prompt set size and the engines tracked.
- Start and end dates, and how often prompts were run.
- Baseline mention rate, citation rate and accuracy.
- The exact changes made, in order.
- The results after 60 to 90 days, plus any business outcome such as leads or bookings.
What is the future of AEO services in digital marketing?
Nobody can predict this with certainty, but several trends are already clear.
- AI answers are spreading. More search experiences now start with an AI summary. Being part of that summary will matter more each year.
- AI agents will act, not just answer. Assistants are starting to compare, book and buy on behalf of users. Clean, structured, machine-readable business data will matter even more.
- Measurement will improve. Expect better reporting from AI platforms and better tracking tools. Early agencies will already have the historical data to compare against.
- AEO will become a standard line item. Just as mobile SEO and local SEO became normal parts of a retainer, AEO will likely fold into everyday SEO work.
- Value will shift to execution. Tracking will get cheaper. The value will be in knowing what to fix next and doing it well.
Agencies that start now get a head start. They build real case evidence, sharpen their process and become the obvious choice when clients start asking.

Frequently asked questions
Is AEO just SEO with a new name?
No. AEO relies on good SEO, but it adds new work. That includes prompt tracking, answer-first content, entity consistency, off-site citations and checking AI answers for accuracy. The goal is being named inside an answer, not just ranking a link.
How long does AEO take to show results?
On-site fixes can show up within a few weeks in engines that search the web live. Changes that depend on off-site authority and reviews usually take two to six months. Set a 90-day review so both sides can judge progress fairly.
Can an agency guarantee a client will appear in ChatGPT?
No. AI answers change from run to run, and no agency controls them. An agency can promise a clear process and honest tracking, and aim for a rising mention and citation rate across a fixed set of questions.
How many prompts should an agency track per client?
Most small clients start with 20 to 30 prompts. Larger or more competitive clients often need 50 to 100. Choose real questions buyers ask at each stage, from early research to comparing options.
Do small local businesses need AEO?
Yes, often more than they think. People ask AI assistants for local recommendations, and assistants can repeat old addresses, hours or services. Basic AEO work fixes those errors and improves the odds of being recommended.
Does schema markup help with AI answers?
Schema helps machines understand who a business is and what a page covers. It is not a magic switch, but clean Organization, LocalBusiness, Service and FAQPage markup supports entity clarity and makes content easier to read.
What should an AEO report include?
A good report shows mention rate, citation rate, answer accuracy and share of voice against competitors for a fixed prompt set. It also lists what changed, the work completed and the next priority actions.
Should clients block AI crawlers?
Blocking AI search bots can stop a site from appearing in those assistants’ answers. Training crawlers are a separate choice. Most businesses that want visibility allow search bots and decide on training bots based on their own content policy.
Start with one client
You do not need a big launch. Pick one client, run a proper AI visibility audit, and show them what AI engines say about their business today. That single report usually makes the case for the service.
SiteSignal helps agencies run those audits, track every client across the major AI engines, and turn the results into weekly action plans. See how SiteSignal works for agencies.
