AEO services promise to get your brand named in AI answers: ChatGPT, Perplexity, Gemini and Google’s AI Overviews. Some of that work is real and worth paying for. A lot of it is ordinary SEO with a new name and a higher price. This post sets out what a real engagement includes, what agencies say it costs in 2026, the red flags, and which parts you can do yourself. It is written for businesses deciding whether to hire, and for agencies deciding what to sell.
SparkToro and Gumshoe.ai had 600 volunteers run 12 prompts 2,961 times[3]. The survey is a vendor survey of 602 US marketing and PR professionals, run by a content agency and an AI visibility vendor[4]. Google’s statement is from its AI features documentation[5].
What “AEO services” actually means
The names overlap. Answer engine optimization services, generative engine optimization services and AI search optimization services are sold as the same thing by most agencies, and the differences are mostly marketing. If you want the concepts, read our guides to answer engine optimization and generative engine optimization, or GEO vs SEO vs AEO for how they relate. This post is about the service: what you get for the money.
Start with the honest part. Google’s own documentation says: “There are no additional requirements to appear in AI Overviews or AI Mode, nor other special optimizations necessary.” It adds that you don’t need to create new machine-readable files or AI text files to appear[5]. Other engines publish less, but most of them search the web and read pages the way a search engine does. So a good share of any AEO engagement, often most of it, is solid SEO: crawlable pages, clear answers, accurate structured data, and a site other sites trust.
What is genuinely new is small but real. First, measurement: nobody hands you a report of which AI answers name you, so someone has to build one. Second, off-site work aimed at the specific pages AI cites for your category, which are often listicles, review sites and forums rather than the usual link targets. Those two are where a service earns its fee.
What a real engagement includes, phase by phase
Agencies package this differently, but a complete engagement covers six things. If a proposal skips one, ask why.
Baseline and prompt set
The baseline is the most important deliverable and the one most often skipped. Without it, any later number is unanchored. It should cover several engines separately, because they disagree, and use prompts written the way buyers ask. A set stuffed with your brand name will show a high mention rate that means nothing. Our post on choosing the prompts for LLM tracking covers how to build one and how many answers a rate needs before you trust it.
Technical audit
Check whether AI crawlers can reach the site at all. A robots.txt rule written years ago can block GPTBot or PerplexityBot without anyone noticing. After that come the usual structure and schema checks. An agency that sells llms.txt as the centrepiece is overselling: it is cheap to publish, but Google says it is not needed, and the evidence that it does anything is thin.
Content and off-site work
Content work should start from the answers, not from a keyword list. Look at which pages AI cites when it answers your buyers’ questions, then make yours the better source. Off-site work follows the same logic. If ChatGPT names your rivals and cites a particular comparison article, a review site or a Reddit thread, that page is the target. Citation analysis shows which sources feed which answers, and our Reddit guide covers how to take part in forums without spamming them.
What you can do yourself, and what is worth paying for
Most of the list is within reach of a business with a competent marketer. The parts that cost real time or contacts are where an agency adds the most.
| Doable in-house | Worth paying for | Why | |
|---|---|---|---|
| Baseline and tracking | ✓Yes | ~ | A tracking tool does the running. Paying helps if nobody has time to read it. |
| Prompt set | ✓Yes | ~ | You know your buyers' words better than an agency does. |
| Crawler access, llms.txt | ✓Yes | ✕No | Free checkers cover it in minutes. |
| Schema and page structure | ~ | ~ | Easy on a simple CMS; worth help on a large or custom site. |
| Content rewrites | ✓Yes | ~ | Needs subject expertise, which you usually have and the agency does not. |
| Listicle, review and PR outreach | ~ | ✓Yes | Takes contacts and persistence. This is where agencies earn their fee. |
| Reporting to leadership | ~ | ✓Yes | Worth paying for if it is honest about variance. |
What AEO services cost in 2026
There is no independent pricing survey for AEO or generative engine optimization services that we could find. What exists is agencies publishing their own ranges. They are useful as a sense of scale, but read them as sellers describing their market.
| Pierview (June 2026) | Gigawatt Group (undated) | |
|---|---|---|
| One-time audit or project | $1,500 to $5,000 (audit) | $5,000 to $15,000 per project |
| Monthly retainer, typical | $3,000 to $15,000 | $2,000 to $10,000 (mid-tier) |
| Entry retainer | $2,500 to $5,000 | From $1,500 (AEO or GEO) |
| Enterprise | $10,000 to $25,000+ | $15,000 to $50,000+ (programs) |
| Hourly consulting | $100 to $250 | $100 to $250 |
Pierview’s guide says most retainers fall between $3,000 and $15,000 a month, and adds that below about $1,500 a month “you are almost certainly buying rebranded SEO”[1]. Gigawatt Group quotes retainers of $2,000 to $20,000+ depending on scope[2]. Both put hourly consulting at $100 to $250.
What moves the price is scope, not the label. A retainer with real off-site outreach and content production costs more than one that runs a tracking tool and sends a monthly summary. So compare proposals line by line against the six deliverables above, not by the headline number. A cheap retainer that includes only reporting may be fine, if reporting is what you need.
Red flags in an AEO proposal
The field is new, the results are hard to measure, and buyers are under pressure. That combination attracts overselling, and AI search optimization services are no exception. These are the claims to push back on.
The spam point deserves a closer look. Google defines scaled content abuse as “when many pages are generated for the primary purpose of manipulating search rankings and not helping users”, and lists “using generative AI tools or other similar tools to generate many pages without adding value for users” as an example[6]. Since AI Overviews and AI Mode draw on Google’s index, an agency whose plan is volume risks the channel it claims to improve.
Two quieter red flags. First, no handling of variance: a report that says you went from 30% to 40% without saying how many answers that rests on. Second, no competitors in the report. Who AI names instead of you is usually the most useful line, and leaving it out makes every month look better than it was.
Engagement scope checklist
Take this into the sales call, or use it to package the service if you are the agency. Tick each item the proposal covers in writing. Your ticks stay in this browser only.
Measuring the baseline with CoreCited
Whichever way you go, the measurement layer is the same. A business can measure its own baseline with CoreCited: it runs your prompt set every week across ChatGPT, Claude, Perplexity, Gemini, Google AI Overviews and AI Mode, and records mentions, citations, Core vs Carousel placement and the rivals named instead. Starter is $69 a month for 40 prompts. The source gap, which sites AI cites for rivals but not for you, starts on Growth, and so do client report links (Growth and up).
An agency can run the measurement and reporting for clients on the Agency plan: $419 a month, 10 brands, 350 prompts and white-label reports. It does not do the outreach or the writing judgement for you; that part is still the service. See pricing for every limit, or the agencies page for how client reporting works. If you report to clients already, our client SEO report template shows where AI visibility fits.
Questions people ask
What do AEO services include?
A real engagement starts with a baseline: how often AI engines name you for a fixed set of buyer questions. Then an audit of crawler access, structure and schema, content work on the pages AI cites, off-site work on the lists, reviews and forums AI already reads, and ongoing measurement reported as trends.
How much do AEO services cost in 2026?
Agency-published guides put one-time audits at about $1,500 to $5,000 and monthly retainers mostly between $2,000 and $15,000, with enterprise work higher. These are agencies describing their own market, without a published method, so treat them as a rough guide.
Is AEO different from SEO?
Mostly not. Google says there are no additional requirements or special optimizations needed to appear in AI Overviews or AI Mode. What is new is measurement: tracking which AI answers name you across engines, and working on the third-party sources those answers cite.
Can an agency guarantee ChatGPT citations?
No. AI answers change from run to run. SparkToro and Gumshoe found less than a 1 in 100 chance that ChatGPT or Google's AI gives the same list of brands twice. An honest agency promises work and measurement, not a position.
Should I hire an AEO agency or do it myself?
If you already have decent SEO and someone who can write, you can do most of it yourself with a tracking tool. Paying makes sense for off-site work, digital PR and technical fixes you cannot staff, and for measurement at a scale you do not have time to run.
