Ranking on Google is one thing. Getting mentioned when someone asks ChatGPT, Gemini, Claude, or Perplexity to recommend a business is another.
That's where Answer Engine Optimization (AEO) and Generative Engine Optimization (GEO) come in. These approaches build on traditional SEO but also consider how AI systems find, interpret, cite, and recommend information.
The agencies below specialize in different parts of that process, from technical optimization and content strategy to digital PR, third-party brand visibility, and AI search analytics.
| Agency | Core Specialty | Best For |
|---|---|---|
| SORN AI | AI brand visibility and monitoring | External visibility and competitive positioning |
| iPullRank | Technical SEO and content engineering | Complex websites and search architecture |
| Seer Interactive | GEO research and search analytics | Data-driven optimization |
| WebFX | AI search optimization and SEO | Integrated marketing campaigns |
| Go Fish Digital | SEO and digital PR | Search and earned-media visibility |
| First Page Sage | GEO and thought leadership | Expertise-led content strategies |
| Avenue Z | Digital PR and communications | Brand authority and media coverage |

Avenue Z brings together digital marketing, earned media, and strategic communications.
Its strengths are particularly relevant to businesses whose AI visibility challenges involve brand recognition, media coverage, and consistent positioning across external sources.
Avenue Z offers a communications-led alternative to agencies centered on technical SEO.
Key services: Digital PR, media relations, brand communications, and digital marketing.
The terms are closely related, but they emphasize different aspects of search optimization.
| Approach | Main Focus | Example |
|---|---|---|
| SEO | Organic search visibility | Improving rankings for a service page |
| AEO | Making information useful for direct answers | Structuring content to answer a customer question clearly |
| GEO | Brand and content visibility in generative AI | Improving how a business appears in AI-generated comparisons |
In practice, AEO and GEO overlap considerably. Both depend on accurate information, useful content, and a strong understanding of what customers are searching for.
The difference is not a fixed technical standard. It is primarily about the search experiences and outcomes being targeted.
An effective campaign starts by identifying the questions potential customers ask.
For example, a business offering payroll services might track:
These prompts reveal different stages of the research process.
From there, an agency can examine three areas:
Website content: Are the company's services, features, and differentiators explained clearly?
External visibility: Does the brand appear in relevant industry publications, comparisons, and discussions?
AI search performance: Which competitors appear in tracked responses, and what sources are cited?
The answers help determine whether the priority should be technical improvements, content development, external coverage, or measurement.
Choose based on the work your business actually needs.
Technical SEO and information architecture may be the priority for a large website. Companies with strong websites but limited external recognition may benefit more from digital PR and third-party visibility.
Businesses with established SEO programs may instead need dedicated AI search monitoring and analytics.
Ask each agency which deliverables are included, which AI platforms are measured, and how it distinguishes brand mentions from cited sources.
Avoid any provider promising guaranteed recommendations in ChatGPT or other AI systems.
No. GEO builds on many established SEO practices while addressing visibility in generative AI experiences.
Structured data can help search systems understand certain information, but it is not a universal requirement for appearing in AI-generated answers.
Yes. Relevant editorial coverage can strengthen a brand's external presence and create opportunities for inclusion in sources used by AI systems.
A mention occurs when an AI response names a brand. A citation identifies a source referenced in the response. They are different outcomes.
Track relevant prompts, brand appearances, cited sources, competitor visibility, and changes over time. Business outcomes such as leads and conversions remain important.
AEO and GEO are not single-service disciplines. Technical optimization, content quality, external brand coverage, and AI visibility measurement each address a different part of the problem.
The best agency depends on whether your business needs to improve its website, strengthen its external reputation, or understand how it appears in AI-generated answers.
