Generative AI is rapidly changing how people discover brands online. Instead of browsing traditional search results, users now turn to tools like ChatGPT, Google AI Overviews, Gemini, and Perplexity to get direct answers, recommendations, and comparisons.
As a result, visibility today is no longer just about ranking links, it’s about being cited, referenced, and recommended inside AI-generated answers. This shift has given rise to a new discipline known as Generative Engine Optimization (GEO).
In this article, we’ve curated a list of the top generative engine optimization agencies in the US, based on GEO focus and AI search expertise.
What Is Generative Engine Optimization (GEO)?
Generative Engine Optimization (GEO) is the process of optimizing your content and brand so that AI tools like ChatGPT and Google AI Overviews can easily understand it and include your business in their answers.
Unlike traditional SEO, which focuses on rankings and clicks, GEO focuses on:
- Being mentioned or cited inside AI-generated responses
- Structuring content so AI can easily extract and reuse it
- Building entity authority and brand trust across the web
- Optimizing for AI crawlers and retrieval systems, not just Googlebot
In short:
SEO helps you rank. GEO helps you get recommended.

Here’s a curated list of agencies that are leading the way in helping brands improve visibility and credibility across AI-powered search experiences.

Their approach uses AI to identify the highest-impact opportunities, focusing on the small set of content and optimization efforts most likely to influence how tools like ChatGPT and Google AI Overviews surface answers. Rather than relying on broad SEO tactics, Graphite emphasizes intent-based questions, personas, and user journeys that align with how people search and ask questions in AI-driven environments.
Graphite combines AEO with SEO and performance growth, using data, experimentation, and reproducible frameworks to turn AI visibility into a scalable growth channel.
Best for:
B2B, SaaS, and product-led growth teams looking to improve AI answer visibility through intent-driven, AI-guided optimization.

Their work emphasizes topic research, content freshness, and digital PR, all of which contribute indirectly to AI visibility. However, GEO is not a standalone service at Siege Media; it is an extension of their broader content-led SEO strategy.

The agency focuses on aligning content and brand signals with how large language models understand, evaluate, and reuse information. This includes improving clarity, structure, authority, and trust signals so AI systems can confidently reference a brand when generating responses.
Key GEO capabilities include:
- AI-answer-focused content strategy with passage-level optimization
- Brand citation building (link building) across high-authority third-party websites
- Entity optimization supported by advanced structured data and schema
- Strategic participation on platforms such as Reddit and Quora, which are commonly referenced by AI models
- Optimization for AI crawler bots that may not fully render JavaScript
What differentiates Growffic is its revenue-centric, full-funnel approach to GEO.

How to Choose the Right GEO Agency
Choosing the right generative engine optimization (GEO) agency requires a different mindset than selecting a traditional SEO partner. While rankings and traffic still matter, AI-driven search places greater importance on trust, clarity, and source credibility.
When evaluating GEO agencies, consider the following factors:
1. Dedicated GEO expertise, not just SEO rebranding
Some agencies offer GEO as an add-on to existing SEO or content services, while others provide dedicated generative optimization programs. Look for clear GEO deliverables, methodologies, and use cases tied specifically to AI-generated answers.
2. Understanding of how AI systems source information
A strong GEO agency should understand how tools like ChatGPT, Google AI Overviews, Gemini, and Perplexity retrieve, summarize, and cite information, not just how search engines rank pages.
3. Focus on entity authority and brand citations
Visibility in AI answers depends heavily on brand authority and third-party references. Agencies should have strategies for entity optimization, structured data, and earning credible brand mentions across the web.
4. Measurement beyond traffic and rankings
Traditional SEO metrics alone don’t tell the full story. The right GEO agency should track AI visibility, brand mentions, and influence on user decisions, not just clicks.
5. Alignment with business outcomes
Ultimately, GEO should support real business goals. Choose an agency that connects AI visibility to trust, demand generation, and conversions rather than treating GEO as a purely experimental channel.
As generative search continues to evolve, working with an agency that has clear GEO capabilities and a practical understanding of AI-driven discovery can make a meaningful difference in how your brand is found, referenced, and chosen.
Final Thoughts
Generative search is already changing how people research and choose brands. As tools like ChatGPT, Google AI Overviews, Gemini, and Perplexity become part of everyday decision-making, visibility now depends on being cited and referenced inside AI-generated answers, not just ranking in traditional search results.
While many agencies are adapting SEO for this shift, Growffic stands out for its focused approach to generative engine optimization, helping brands improve AI visibility, build credibility, and connect that visibility to real business outcomes. For companies looking to stay competitive as search continues to evolve, investing in Generative Engine Optimization Services is no longer optional.
