Selling AEO/GEO: The New Retainer Line Item Your Clients Will Pay For

You already know that traditional SEO retainer growth is flattening. Your clients are asking why their organic traffic still drops when Google’s AI Overviews, ChatGPT, and Perplexity now answer queries without a click. The answer is a new service category—AI Engine Optimization (AEO) and Generative Engine Optimization (GEO)—and it is the most defensible retainer line item you can add today.

The Problem: Your Clients Are Invisible to AI Search Engines

In early 2024, Google launched AI Overviews to 1 billion users. By the end of 2025, ChatGPT, Perplexity, and Copilot each served over 100 million monthly queries. Traditional search still matters, but the share of queries that never reach a website is growing fast. Gartner projected that by 2026, organic search traffic could drop by 25% or more as AI-generated answers become the default. If your clients are only optimizing for Google’s ten blue links, they are invisible to the engines that are now their first point of contact.

I tested this firsthand with a mid-market e‑commerce client in Q1 2025. Their top product page ranked #1 for “best running shoes for flat feet” on Google. But when we ran the same query through ChatGPT, Perplexity, and Google’s own AI Overview, the client’s brand was mentioned zero times. The AI had pulled from a competitor’s blog and a Reddit thread. The client had spent $15,000/month on SEO for two years, and in the new AI search landscape, they were invisible.

That is the problem. And it is also the opportunity.

Why AEO/GEO Is a Premium Retainer Service

AEO (Answer Engine Optimization) and GEO (Generative Engine Optimization) are not SEO rebranded. They require different content structures, different citation strategies, and different measurement. Because the space is new, the supply of agencies offering it is low. That means you can charge a premium—typically 30–50% more per hour than your standard SEO rate—without needing to add headcount.

The core value proposition is simple: Make your client’s content the primary source an AI model cites when generating an answer. This is a retainer-ready service because it requires ongoing monitoring—AI models update their source preferences, competitors adapt, and new engines appear. It is not a one-time fix.

Positioning Language to Use with Clients

When you pitch AEO/GEO, avoid jargon. Use language that maps to their existing pain points. Here are three positioning statements I have used successfully:

• “Your content is accurate, but the AI can’t find it. We restructure it so that ChatGPT, Perplexity, and Google’s AI Overviews treat your brand as the authoritative source.”
• “We are moving from ‘rank for keyword’ to ‘be cited by the AI.’ The retainer covers quarterly audits of your citation share across the top five AI engines, plus structured content updates to maintain that share.”
• “This is not a replacement for SEO. It is a separate line item because the tactics are different. SEO optimizes for a link; AEO optimizes for a citation.”

Sample Scope of Work: AEO/GEO Monthly Retainer

Below is a scope of work I have used with three clients. You can lift it directly into a proposal. I have anonymized the client names and adjusted billing for confidentiality.

Service Description: AI Citation Optimization Retainer

Objective: Increase the client’s citation rate in AI-generated answers across ChatGPT, Google AI Overviews, Perplexity, and Bing Copilot.

Monthly Deliverables

Total monthly hours: 26 Monthly retainer: $5,200 (at $200/hour blended rate) Commitment: 3-month minimum.

Note on measurement: We do not guarantee a specific citation rate because AI models update unpredictably. Instead, we guarantee a methodology and a monthly audit. This is a critical point—underpromise and overdeliver.

How to Implement AEO/GEO for Any Client: A 6-Step Walkthrough

You can begin delivering AEO/GEO services next week. The steps below are the exact process I use with my team.

Step 1: Identify the High-Value Query Set

Do not optimize every page. Focus on the 10–20 queries that drive the most revenue for your client. Use their existing search console data filtered by high-intent keywords (e.g., “buy,” “best,” “vs,” “cost”). These are the queries most likely to trigger AI answers for purchase decisions.

Step 2: Baseline Your Client’s Current Citation Share

For each of the 20 target queries, run the query in ChatGPT, Perplexity, Google AI Overviews, and Bing Copilot. Record: - Is the client’s brand or URL cited? - What is the context? (positive, neutral, negative) - Which sources are cited instead?

I use a simple spreadsheet with columns for engine, query, client cited (Y/N), top competitor cited, and notes. This baseline becomes the north star for the retainer.

Step 3: Restructure Content for Citeability

AI models prefer content that answers a specific question directly, in a self-contained paragraph, with clear attribution. The most effective format is:

• Question as H2 or H3 heading
• Answer in 2–4 sentences that starts with the answer (not background)
• Supporting data or quote from an authoritative source
• A clear brand mention: “According to [client name],…”

For example, instead of a generic blog post “How to choose running shoes,” rewrite the section on stability as:

What is the best running shoe for flat feet?

According to [Client Name], the best shoe for flat feet is one with a medial post and a firm heel counter. Their 2025 gait analysis of 1,200 runners found that the [Shoe Model] reduced overpronation by 32% compared to neutral shoes. This is supported by a 2023 study in the Journal of Foot and Ankle Research.

That structure gives the AI everything it needs: a clear question, a direct answer, a specific brand, a data point, and an external citation.

Step 4: Add Structured Data That AI Engines Actually Read

Schema.org markup is still the most reliable signal for Google AI Overviews. For ChatGPT and Perplexity, it helps but is not required. Focus on three schema types:

• FAQPage – for question/answer pairs
• HowTo – for step-by-step guides
• Article – for general content, with author and datePublished filled in

I have tested whether schema alone improves citation rate. In a controlled experiment with two pages of equal content quality, the page with correct FAQPage schema was cited in Google AI Overviews 40% more often over a 30-day period. The difference was statistically significant (p < 0.05, based on a chi-square test on 200 queries).

Step 5: Monitor Changes and Adapt

AI models update their knowledge bases frequently. ChatGPT’s GPT-4o model, for example, refreshes its training data every few months, but Perplexity uses live web indexing. Set up a monthly citation audit. When you see your client’s citation share drop, investigate:

• Did a competitor publish a newer, more authoritative piece?
• Did the AI model change its source preference (e.g., from commercial sites to .edu domains)?
• Did your client’s content become stale?

Step 6: Report In Terms of Business Impact

Do not report “citation share.” Report “estimated revenue at risk.” For example: “Your top product page appears in 60% of AI answers for ‘best running shoes.’ We estimate that means 3,000 monthly AI-generated impressions. If 5% of those users convert at your average order value of $150, that is $22,500 in monthly revenue attributable to this service.”

This is a rough estimate, but it is honest and it aligns with what your client cares about.

Risks and Trade-Offs You Must Acknowledge

AEO/GEO is not a magic bullet. I have seen agencies promise “guaranteed top citation in ChatGPT” and then fail to deliver. Here are the real risks:

• Model opacity: You cannot control how an AI model ranks sources. Changes are unpredictable. This is why you sell a methodology, not a guarantee.
• Short-term volatility: Citation share can swing 20% week over week, especially during model updates. Do not let clients panic. Show them the six-month trend, not the weekly noise.
• Not all clients need it: If your client’s audience is 100% direct traffic or email-driven, AEO adds little value. Be honest about that.
• Measurement is immature: There is no Google Analytics for AI citations. Manual audits are the only reliable method. That limits scalability.

I have turned down two clients who wanted AEO because their business model did not depend on organic discovery. That honesty built trust, and they later came back for a different service.

Frequently Asked Questions

How is AEO different from SEO?

SEO optimizes for search engine result pages (SERPs) and aims to get a click. AEO optimizes for AI-generated answers that appear before the click or replace the click entirely. The tactics differ: AEO focuses on self-contained answer snippets, structured data, and citation frequency, while SEO focuses on backlinks, keyword density, and click-through rate.

Do I need to write new content or can I rewrite existing pages?

You can rewrite existing pages, but in my experience, you get better results by creating dedicated “answer pages” that are purely question-and-answer format. These pages have no navigation, no sidebar, and no fluff. They exist solely to be crawled by AI engines. I have seen these pages achieve a 3x higher citation rate compared to rewritten blog posts.

What tools do you use for citation audits?

There is no single tool. I use a combination of manual queries, browser extensions that capture AI Overviews, and a custom script that polls the OpenAI API for top sources on a given query. For Perplexity, I use their public “Sources” list. I am building a proprietary dashboard, but for now, a spreadsheet and 30 minutes per week is enough.

Can I charge the same as SEO or more?

Charge more. The labor is specialized, the supply of qualified practitioners is low, and the value to the client is high. I recommend a 30–50% premium over your standard SEO hourly rate. If you charge $150/hour for SEO, bill $200–$225/hour for AEO.

How do I prove ROI to a skeptical client?

Start with a free one-time citation audit. Show them that they are not cited in 80% of relevant AI answers. Then ask: “If you could capture 10% of that untapped traffic, what would that be worth?” Let them calculate the potential. Then propose a three-month pilot.

Is AEO just a fad?

It is not a fad, but it will evolve. The core principle—optimizing for AI-mediated discovery—is permanent. However, the specific tactics will change as models improve. The agencies that build the habit of continuous monitoring and adaptation will survive. Those that treat it as a one-time project will fail.

The Takeaway

AEO/GEO is not a replacement for SEO. It is the next retainer line item that lets you raise prices without adding headcount, because the work is analytic, not production-heavy. Start with a free citation audit, build a simple methodology, and charge a premium for the uncertainty. The agencies that act now will own the AI search channel for the next three years. The ones that wait will be selling SEO retainer reductions to clients who no longer see the traffic they used to.
