AEO Agency Pricing in 2026: Retainers, Audits and Project Fees Compared

AEO agency quotes in 2026 run from about $1,000 a month to more than $25,000 a month, according to published agency benchmarks, and most buyers can't tell what separates the two ends. Same acronym, same promise of ChatGPT citations, a 25x price gap.

This guide lays out the published price bands, what each band should actually deliver, how agencies compare with a consultant or an in-house hire, and the contract terms to refuse. Every number below links to its source.

Key Takeaways

• Most mid-market AEO agency retainers land between $2,000 and $10,000 a month.
• Off-site authority work, not content volume, drives the top of the price range.
• Retainers under roughly $2,500 a month usually buy monitoring and reporting, not citation growth.
• Refuse 12-month lock-ins and guaranteed ChatGPT placements on a service this new.
• Austin Heaton's engagements start at $5,000 a month, scoped on /pricing.

How Much Does an AEO Agency Cost in 2026?

An AEO agency costs roughly $2,000 to $10,000 a month for a mid-market business in 2026, with monitoring-only plans below that and enterprise programs above $10,000. That's the modal range in OpenLens's 2026 AEO pricing benchmarks, which it cross-references against more than 60 agency proposals.

A separate agency rate survey from Presenc AI (March 2026, 94 GEO or combined agencies) puts the median GEO retainer at $4,500 a month, against $6,200 for SEO retainers.

What Drives the Price of an AEO Retainer?

Three things move an AEO quote more than anything else: how much off-site authority work is included, how many engines and prompts are tracked, and how many pages get built or rebuilt each month.

Here's how each factor shows up in a proposal.

• Off-site authority. Brand mentions, third-party authority posts and backlinks are the expensive, slow part of AEO. They're also what gets a brand named by models that already trust certain publications.
• Engine and prompt coverage. Tracking 25 prompts on two engines is a very different job from tracking hundreds of prompts across ChatGPT, Perplexity, Gemini, Claude and Google AI Overviews.
• Page production. Comparison pages, alternatives pages and answer-first blogs take senior writing time. A plan with zero new pages is a reporting plan.
• Category competition. Payroll, payments and cybersecurity prompts are crowded. Winning a shortlist spot there takes more citations than winning a niche prompt.
• Reporting depth. Share of voice by prompt, cited source domains and pipeline attribution cost more to produce than a screenshot deck.

That's why Presenc AI's survey found GEO pricing rising 22% a year while SEO pricing rises 6%: the off-site half of the work is labor-heavy, and qualified practitioners are scarce.

Retainer vs Project vs Hourly: Which AEO Pricing Model Fits?

Monthly retainers dominate AEO pricing because citations decay without refreshes, but project fees and hourly advice both have a place.

If you still need proof that AI search matters for your category, start smaller. The Free AEO Report Card shows where AI answers skip your brand before you spend anything, and a technical AEO audit is the next step up.

What Should Each AEO Price Band Actually Deliver?

Every band should come with deliverable counts. If a proposal says "ongoing optimization" with no numbers, you can't enforce it.

Use the OpenLens tier definitions as a checklist when you read a quote:

• Monitoring tier: a monthly visibility report on 25 to 50 prompts across 3 to 5 platforms, with competitor share of voice.
• Active optimization tier: the above plus a schema audit, citation and directory seeding, and a quarterly prompt-set refresh.
• Full AEO plus content tier: 4 to 8 quotable content pieces a month, FAQ rebuilds, PR-led citation seeding into trade publications and a monthly executive review. OpenLens notes this tier often carries a 6-month minimum.
• Enterprise tier: multi-region or multi-language tracking, a dedicated analyst and custom reporting.

For comparison, the Build the foundation plan on austinheaton.com lists 4 money pages a month for the first 60 to 90 days (then 1 a month), 8 MOFU/BOFU blogs a month, a monthly content refresh, 3 authority posts, 10 brand mentions and 5 backlinks a month. Those counts are what the starting quote buys.

AEO Agency vs Consultant vs In-House: What Does Each Cost?

An agency isn't the only way to buy AEO, and for many B2B teams it isn't the cheapest per unit of senior attention.

AEO Agency Pricing Red Flags to Refuse

Most bad AEO contracts fail on terms, not price. Walk away from these.

• 12-month lock-ins. OpenLens notes reputable agencies offer 6-month initial terms with month-to-month after that.
• Guaranteed ChatGPT citations. AI engines are non-deterministic, so no one can guarantee a placement, as MarketerHire's guide points out.
• "Unlimited" AEO for a few hundred dollars a month. That's scripted prompt tracking dressed up as optimization.
• Schema-only scopes. Schema helps retrieval. It doesn't earn mentions on the third-party pages models trust.
• Citation count as the only KPI. Counts are easy to inflate with low-quality forum mentions. Ask for share of voice on your top buyer prompts and pipeline from AI referrals.

AEO Agency Pricing FAQ

How much does an AEO agency charge per month?

Most mid-market AEO agencies charge $2,000 to $10,000 a month in 2026, per OpenLens benchmarks. Monitoring-only plans start near $1,000, and enterprise programs run past $25,000.

Is AEO more expensive than SEO?

Not on average yet. Presenc AI reports a median GEO retainer of $4,500 a month versus $6,200 for SEO, but GEO pricing is rising faster.

Why do AEO agency quotes vary so much?

Scope. Off-site authority work, the number of engines and prompts tracked, and monthly page production drive most of the difference between a $2,000 and a $10,000 quote.

What contract length is normal for an AEO agency?

A 6-month initial term, then month-to-month, is the common reputable structure. Treat a 12-month lock-in on a service this new as a red flag.

Should I hire an AEO agency or a consultant?

Hire an agency when you need parallel production at high volume. Hire a senior consultant when you want one owner doing the work; Austin Heaton compares both on AEO consultant vs agency.

How much does Austin Heaton charge for AEO?

Austin Heaton's engagements start at $5,000 a month. The final quote depends on scope, category coverage and off-site cadence, as set out on the pricing page.

What to Do Before You Sign an AEO Retainer

Before you compare quotes, run your own top five buyer prompts in ChatGPT and Perplexity and write down who gets recommended. That list tells you how big your citation gap is, and the gap is what you're really pricing.

Then ask every agency for deliverable counts, the contract term and the KPI they'll report on. Anyone who can't answer all three in writing isn't ready for your budget.
