Generative Engine Optimization Companies: How to Evaluate GEO Agencies in 2026

The market for generative engine optimization companies has expanded rapidly as businesses recognize the importance of AI search visibility. Dozens of agencies now offer GEO services—but capabilities, approaches, and results vary significantly. Choosing the wrong partner means wasted investment and missed opportunities in a channel that's becoming increasingly competitive.

This guide helps you evaluate GEO companies based on what actually matters: proven methodologies, measurable results, and alignment with your specific business needs.

What GEO Companies Actually Do

Generative engine optimization companies help brands appear in AI-generated responses from ChatGPT, Perplexity, Google AI Overviews, and similar platforms. Unlike traditional SEO focused on rankings, GEO focuses on citations—getting AI systems to reference and recommend your brand when answering user queries.

Core GEO service components:

AI visibility auditing: Assessing current citation frequency, accuracy, and competitive positioning across AI platforms.

Content optimization: Restructuring existing content for AI extractability—answer-first formatting, quotable paragraphs, and citation-ready statistics.

Entity authority building: Ensuring consistent brand information across web properties that AI systems cross-reference.

Technical implementation: Structured data, schema markup, and technical factors that help AI systems understand your content.

Authority development: Strategies to build the external signals (backlinks, mentions, PR) that AI platforms evaluate when deciding who to cite.

Performance monitoring: Tracking citation frequency, accuracy, and competitive share of voice across AI platforms.

Categories of GEO Service Providers

Full-Service GEO Agencies

These companies offer comprehensive GEO programs including strategy, execution, and measurement. They typically serve as strategic partners rather than tactical vendors.

Characteristics:

  • Dedicated GEO teams with specialized expertise
  • Proprietary frameworks and methodologies
  • Long-term engagement models (6-12+ month programs)
  • Integrated services spanning content, technical, and authority building
  • Regular reporting and strategy refinement

Best for: Companies prioritizing AI visibility as a strategic channel, mid-market to enterprise organizations with budget for comprehensive programs.

GEO-Focused Consultancies

Smaller firms specializing exclusively in generative engine optimization. They often work with clients who have SEO handled elsewhere.

Characteristics:

  • Deep GEO specialization without broader SEO services
  • Often founder-led with hands-on expertise
  • Flexible engagement models
  • May require separate SEO relationships

Best for: Companies with established SEO programs needing dedicated GEO expertise.

Investment range: $2,500-10,000+ monthly

Best for: Organizations wanting technology-enabled GEO with optional managed services.

Investment range: $500-5,000+ monthly (software plus services)

Evaluation Criteria for GEO Companies

Proven Methodology Over Hype

The GEO space attracts agencies making bold claims without substance. Evaluate based on methodology, not marketing.

Questions to ask:

  • What specific tactics does your GEO methodology include?
  • How do you prioritize optimization efforts?
  • What's your approach to measuring success?
  • How do you adapt when AI platforms change their behavior?

Strong agencies explain their approach clearly and specifically. Vague answers about "AI optimization" without tactical depth indicate limited experience.

Demonstrated Results

Request case studies with measurable outcomes. Credible GEO companies can show:

  • Before/after citation frequency changes
  • Competitive share of voice improvements
  • Accuracy improvements in AI brand mentions
  • Traffic and conversion impact from AI referrals

Be skeptical of agencies showing only rankings improvements—that's SEO, not GEO. GEO results should demonstrate AI platform citation changes specifically.

AI Platform Expertise

Different AI platforms have different behaviors. ChatGPT, Perplexity, and Google AI Overviews each weight factors differently. Effective GEO companies understand these distinctions.

Questions to ask:

  • How does your approach differ across ChatGPT, Perplexity, and Google AI Overviews?
  • What research informs your understanding of AI platform behaviors?
  • How do you stay current as AI platforms evolve?

Agencies claiming one approach works identically across all platforms lack nuanced understanding.

Integration with SEO

GEO and SEO share foundational elements. Strong GEO builds on SEO fundamentals rather than treating them as separate disciplines.

Red flags:

  • Agencies dismissing traditional SEO as irrelevant
  • GEO strategies that ignore technical site health
  • Approaches focused only on content without authority building

Green flags:

  • Clear explanation of how GEO extends SEO
  • Integrated optimization serving both channels
  • Understanding that strong SEO improves GEO outcomes

Transparency and Reporting

GEO measurement is evolving. Honest agencies acknowledge measurement challenges while providing meaningful progress indicators.

Expect:

  • Regular citation tracking across platforms
  • Competitive share of voice analysis
  • Content performance relative to optimization efforts
  • Clear communication about what can and cannot be measured

Avoid agencies that:

  • Promise specific citation outcomes they cannot control
  • Lack systematic tracking capabilities
  • Provide vague "AI visibility improved" reports without data

Questions to Ask Prospective GEO Companies

About Their Experience

  • How long have you been providing GEO services specifically?
  • What industries have you served with GEO programs?
  • Can you share case studies with quantified results?
  • Who on your team specializes in GEO versus general SEO?

About Their Approach

  • Walk me through your typical GEO engagement process.
  • What audits and analysis do you perform before strategy development?
  • How do you prioritize which content and topics to optimize?
  • What's your timeline for seeing measurable results?

About Execution

  • What ongoing work happens after initial optimization?
  • How do you handle content creation versus optimization of existing content?
  • What's your approach to authority building for GEO?
  • How often do you review and adjust strategy?

About Measurement

  • What metrics do you track for GEO performance?
  • What tools do you use for AI visibility monitoring?
  • How do you report progress and results?
  • What results can realistically be expected in 3, 6, and 12 months?

Red Flags When Evaluating GEO Companies

Guaranteed citations

No agency can guarantee AI platforms will cite specific content. AI citation decisions happen within systems agencies don't control.

GEO without SEO foundation

Companies dismissing traditional SEO fundamentals misunderstand how AI platforms evaluate sources. Strong SEO supports GEO success.

Quick-fix promises

GEO authority builds over months, not weeks. Agencies promising rapid results likely deliver temporary tactics, not sustainable visibility.

Lack of measurement capabilities

GEO requires tracking citations across multiple AI platforms. Agencies without systematic monitoring can't demonstrate or optimize results.

One-size-fits-all approaches

Different industries, audiences, and competitive landscapes require tailored strategies. Templated approaches underperform.
