Below: what each layer actually involves, what lands in month one versus month six, what changes the price, how to tell a real AEO provider from an SEO shop that bolted on the acronym, and the four ways these engagements go wrong.

The four layers of an AEO engagement

Answer engine optimization is not a single deliverable. It is four layers, and skipping one makes the others do nothing. If you want the concept before the scope, we keep answer engine optimization explained as a standalone reference.

Access. An answer engine cannot cite a page it cannot fetch. This layer covers robots.txt rules that separate AI retrieval crawlers from training crawlers, server responses that do not block or throttle them, render behaviour that does not hide the content behind JavaScript, and the optional llms.txt file. Most access problems are accidental. A security plugin, a CDN rule, or a copied robots.txt file blocks something nobody meant to block.

Structure. Semantic HTML, one H1, headings that describe the section under them, and JSON-LD that matches what a human sees on the page. Organization or LocalBusiness schema with real depth, Article or BlogPosting on editorial pages with author and publish date, BreadcrumbList, and FAQPage only where visible questions and answers exist. Schema that describes content the page does not contain is worse than no schema.

Substance. Content written to answer a question in the first two sentences, with the claim stated before the context. Named authors with a real bio and a page that establishes why they know the subject. Sourced facts. Dates that reflect reality. This layer is where most of the recurring monthly work goes, because it is the layer that never finishes.

Authority. Off-site citations and mentions on sources the engines already read. This is the slowest layer and the one that separates a foundational retainer from a full-stack one.

Wrapped around all four is measurement: a fixed set of queries that matter for your category, sampled repeatedly, so you can see whether anything moved.

What actually lands, month by month

Month one is diagnosis and structural fixes. Full audit against the checks that matter, crawler access corrected, schema written or repaired so it matches the page, single H1 enforced, meta descriptions written, sitemap and lastmod dates made factual, author attribution added. Then a baseline: the query set is defined and sampled so there is a before to compare against.

Months two and three are content and coverage. New pages that answer the questions your buyers type, existing pages rewritten so the answer arrives first, FAQ sections added where there are real questions to answer and schema to match. Coverage of the entity gaps found in month one, meaning the questions about your category where nothing on your site is a plausible source.

Month four onward is authority and iteration. Off-site work, refreshed content on the pages that matter, and monthly re-sampling of the query set. This is where the engagement either compounds or stalls, and it depends almost entirely on whether the content layer keeps shipping.

You can see the diagnosis half yourself before paying anyone. Our free AEO audit runs 13 checks worth 66 points and scores a page into four tiers, with Strong at 85% or above and Decent at 65% or above. It is the same rubric we run on client sites and on our own.

What it costs

Three real price points, all separate from your own team's time. For the market-wide breakdown, here is what AEO costs in detail.

Free, if you do it yourself. Access, structure, and single-page fixes are a weekend of work for someone technical. Run the audit, fix what it flags, add the schema, name your authors. The ceiling on DIY is the content and authority layers, which take recurring hours nobody has.

$1,950 a month, foundational. Crawlable content, retrieval access, accurate schema, named authorship, and monthly content. Optional llms.txt and FAQ markup for visible Q and A sit inside that scope. This is the right tier for a local or small business with one market and one product line.

$4,500 and up, growth and authority. Growth sits at $4,500 and suits scaling DTC and B2B. Authority starts at $7,500 for category leaders. Across the market, engagements covering content volume, off-site authority, multi-engine monitoring, and iteration run from $5,000 to $15,000 a month.

What moves the number: how many categories and questions you need to cover, how often the content has to be refreshed, how much content gets produced per month, whether off-site authority work is included, and how many engines get tracked.

Two pricing signals to walk away from. Dirt-cheap AEO, because at a few hundred a month the only thing that fits in the budget is a schema plugin and a report. And hidden pricing, because an agency that will not publish a starting number is usually pricing off what it thinks you can pay.

How to evaluate an AEO provider

Five checks, all answerable on a first call. The longer version is the 7 questions to ask a provider.

1. Do they separate what they control from what they do not? Nobody controls source selection inside an answer engine. A provider that says so out loud is describing the job accurately. A provider guaranteeing citations is not.
2. Do they track more than one engine? ChatGPT, Perplexity, Google AI Overviews, and Claude select sources differently. A report on one engine is a sample of one, and tracking citations across engines takes dedicated tooling.
3. Is there a named human on the content? Authorship is a ranking-adjacent signal and also a proxy for whether real people are writing.
4. Do they do SEO too? AEO and SEO share the same technical foundation. A provider that treats them as separate products will bill you twice for the same crawl fix.
5. Will they show you the audit before the invoice? The diagnosis is cheap to produce. Anyone unwilling to show their assessment before you sign is protecting a thin process.

The four ways AEO engagements go wrong

Schema that lies. FAQPage markup with no visible FAQ on the page. Review schema for reviews that are not shown. It is the most common shortcut in the category and it is the one that gets pages penalised rather than cited.

Blocking the wrong crawlers. Teams read a headline about AI training and block everything, including the retrieval crawlers that fetch a page at the moment a user asks a question. Training access and live retrieval access are different decisions and should be made separately, and the gap between retrieval crawlers versus training crawlers is where most of the damage happens.

Treating AEO as a replacement for SEO. It is not. Organic rankings and AI citations are measured separately and both are worth having. The technical work underneath them is shared. Here is how AEO and SEO differ in practice.

No baseline. If nobody recorded how the brand appeared across a fixed query set before the work started, there is no honest way to say whether anything improved. Establish the baseline in week one or the reporting is theatre.

The scale of the gap is why this is worth doing now. We audited 152 Calgary businesses against our own rubric. Zero scored Strong. The average was 44%. The structural bar is low and almost nobody has cleared it.

Frequently asked questions

What are AEO services?

AEO services cover the technical and content work that makes a site retrievable and citable by answer engines. That means crawler access, semantic structure, accurate JSON-LD schema, named authorship, content that answers questions directly, off-site authority, and monitoring of how a brand appears across ChatGPT, Perplexity, Google AI Overviews, and Claude.

How much do AEO services cost?

Foundational retainers start at $1,950 a month and cover crawlable content, retrieval access, accurate schema, named authorship, and monthly content. Growth is $4,500 a month, and Authority starts at $7,500. Across the market, full-stack engagements including authority work and multi-engine monitoring run $5,000 to $15,000 a month. The DIY version costs nothing but your own hours.

Can an AEO provider guarantee I get cited by ChatGPT?

No. Answer engines control their own source selection, so no agency can promise a citation, an engine order, or a fixed timeline. What a provider can commit to is the process: observable technical checks, markup that matches the page, and consistent measurement against a stable query set.

Do AEO services replace SEO?

No. They share infrastructure, including technical health, useful content, and authority. SEO measures rankings and organic traffic. AEO adds retrieval readiness and source monitoring for AI answers. Run both and measure each outcome separately.

How long before AEO services show anything?

Structural fixes are visible immediately, because you can re-run an audit and see the checks pass. Citation changes have no fixed timeline and vary by category, query, and engine. Establish a baseline query set at the start so the comparison is real rather than remembered.
