As AEO has gone from niche concept to budget line item, a wave of agencies and consultancies now offer it as a service — some as a dedicated specialty, most bundled into existing SEO or digital marketing retainers. This guide covers what these companies actually do, what to expect to pay, how to evaluate one before signing, and what to do if you'd rather skip the agency fee entirely.

What an AEO Company Actually Does

Strip away the marketing language, and a competent AEO engagement covers four core activities:

1. Baseline measurement

Auditing your current visibility across ChatGPT, Claude, and Gemini to establish where you stand before any work begins.

2. Content & structure work

Building question-answering content, adding FAQPage/Article schema, and restructuring existing pages to be more citable.

3. Third-party citation building

Pursuing mentions on review sites, directories, and publications that AI engines weight heavily — similar to backlink building, but citation-focused.

4. Ongoing re-measurement

Re-auditing visibility on a regular cadence to show whether the work is actually moving scores.

If an agency's pitch skips straight to deliverables without first measuring your baseline, that's a sign they're treating AEO as a content add-on rather than a measurable discipline.

Red Flags When Evaluating an Agency

Watch for: agencies that can't show you a before/after AI visibility score for a past client, that only talk about Google rankings rather than ChatGPT/Claude/Gemini specifically, or that promise guaranteed AI "ranking" — AI engines don't have a ranking position in the traditional sense, and any agency claiming to guarantee one doesn't understand how this actually works.

Questions to Ask Before Hiring

The DIY Alternative

Not every business needs to pay agency rates for AEO. The highest-leverage first step — measuring your current visibility — can be done yourself with a self-serve audit tool for a fraction of the cost of even a single agency consultation. From there:

When an agency does make sense: if you lack internal content/dev capacity, operate in a competitive vertical where dedicated strategy matters, or need someone accountable for consistent execution over months. For most early-stage AEO efforts, though, the DIY path covers 80% of the value at a fraction of the cost.

Frequently Asked Questions

What does an answer engine optimization company actually do?
A good AEO agency audits your current visibility across ChatGPT, Claude, and Gemini, identifies content and structural gaps, builds question-answering content and schema markup, pursues third-party citations and review site presence, and re-measures over time to show whether visibility is improving.
How much does an AEO agency cost?
AEO agency retainers commonly range from $2,000 to $15,000+ per month depending on scope, similar to traditional SEO agency pricing. Many agencies bundle AEO into broader SEO or content marketing retainers rather than selling it standalone.
Do I need to hire an agency for answer engine optimization?
Not necessarily. Many of the highest-leverage AEO activities — measuring your current visibility, identifying which third-party sites to target, and structuring existing content with schema — can be done in-house with the right tools. An agency makes sense when you lack the internal capacity to execute consistently or want specialized strategy.
How do I evaluate an AEO agency before hiring them?
Ask them to show a baseline AI visibility audit for a past client and the before/after results. Ask what specific metrics they track and how often they re-measure. Be wary of agencies that can't explain how they measure success across ChatGPT, Claude, and Gemini specifically, rather than just general SEO metrics.
