The Short Answer: The top AI SEO experts in the US are agencies such as 20North, iPullRank, Omniscient Digital, First Page Sage, and Siege Media, that have moved beyond traditional search optimization to build strategies that get brands cited, mentioned, and recommended by AI platforms like ChatGPT, Google AI Overviews, and Perplexity. This guide breaks down the best options in the country so you can find the right partner for your business.
How AI is Changing the SEO Landscape
Search engine optimization has changed. And it has changed fast.
Not long ago, getting to page one on Google was the finish line. Today, a growing share of your potential customers are skipping the search results page entirely and going straight to AI-generated answers. They ask ChatGPT for recommendations. They use Google's AI Overviews to get answers without clicking. They trust Perplexity to pull together research on their behalf.
If your brand is not showing up in those AI-generated responses, you are losing ground in an increasingly competitive landscape, often without realizing it. That is why finding the right AI SEO expert matters more now than it ever has, whether you are a national brand or a local business trying to grow your online presence.
This guide covers the top AI SEO experts and agencies in the US, what makes each one stand out, and what to look for when you are ready to choose a partner.
What AI SEO Actually Means
AI SEO, also called Generative Engine Optimization (GEO) or Answer Engine Optimization (AEO), is the practice of optimizing your content and digital presence so artificial intelligence systems can find, understand, and cite your brand. It goes beyond traditional SEO tactics like keyword research and link building and requires that your content be structured in a way that large language models (LLMs) can parse and trust.
The agencies setting the standard are combining technical SEO fundamentals with newer strategies around content authority, entity optimization, schema markup, and E-E-A-T signals (Experience, Expertise, Authoritativeness, Trustworthiness). The best practice across the board is to treat AI visibility not as a separate effort, but as a natural extension of a well-built organic search strategy.
The Top AI SEO Experts in the US
20North Marketing
20North Marketing is a full-service digital marketing agency based in Atlanta that has built AI visibility tracking and generative engine optimization directly into its core methodology. Rather than treating GEO as an add-on service, 20North takes a holistic approach to search visibility, testing what works across AI platforms, tracking citation patterns, and delivering actionable insights based on actual performance data.
20North works with mid-market businesses across e-commerce, service, and SaaS industries, with clients like BRUCE BOLT, Peter Glenn, Malta Dynamics, SuitShop, Roam, and SAM Medical. As a Shopify Premier Partner and Klaviyo partner, the agency brings deep technical expertise alongside its organic and paid media work, and their case studies reflect a consistent ability to drive measurable results across a wide range of industries and unique needs.
What sets 20North apart for businesses evaluating AI SEO partners is the combination of channel expertise and strategic depth. The team handles SEO, Google Ads and paid media, email marketing, and web development under one roof, which means AI visibility strategies are built into the broader marketing picture rather than siloed in one channel. The result is a competitive advantage for growing businesses: a high-quality, revenue-focused digital strategy that drives qualified leads, increases organic traffic, and builds sustainable growth over time.
iPullRank
iPullRank is a New York-based enterprise SEO agency founded by Michael King, a well-known figure in the SEO industry. The agency is known for developing "relevance engineering," a framework that merges content strategy, information retrieval, and artificial intelligence to help brands earn citations across search surfaces. They work primarily with enterprise clients like SAP and Nordstrom, addressing the unique challenges that come with large, complex websites and high-stakes search visibility. For organizations with technical complexity and enterprise-level budgets, iPullRank is one of the more credible AI SEO figures.
Omniscient Digital
Omniscient Digital is a boutique agency co-founded by former HubSpot growth marketers, and that background shows in how they approach online visibility. Their signature "Surround Sound" SEO strategy focuses on getting a brand mentioned across the top third-party resources in its category, building the kind of broad authority that directly influences how AI systems select sources to cite. Their client roster includes Asana, Loom, and Jasper. For mid-market B2B brands navigating the competitive landscape of AI search and looking for a more hands-on agency partner, Omniscient Digital brings GEO depth and a record of delivering organic traffic growth.
First Page Sage
First Page Sage is a San Francisco-based agency that has been in the content and SEO space since 2009. They focus on building topical authority through high-volume, research-driven publishing calibrated to how Google search and AI platforms evaluate expertise. Most of their work serves B2B companies in SaaS, medtech, and financial services. They emphasize a long-term thought leadership content program built around AI citation.
Siege Media
Siege Media is an Austin-based content marketing agency that has adapted to the shifting digital landscape of AI search. Their GEO approach uses proprietary tools, BlueprintIQ and DataFlywheel, to close content gaps, improve user experience signals, and structure blog posts and long-form content for LLM citation. They work with SaaS, fintech, and e-commerce brands, with notable results for Zendesk, Zapier, and Figma. Their strength is in producing high-quality, authoritative content that AI platforms prefer to cite at scale.
Quick Comparison
What to Look for in an AI SEO Expert
GEO is still a developing field. Many agencies have added "AI SEO" to their service menus without meaningful expertise behind it. Here is how to evaluate whether a potential partner actually knows what they are doing:
- Documented methodology: Can they explain how they optimize for AI overviews, ChatGPT, and Perplexity specifically? Not just in general terms, but with a clear process tied to how the search algorithm actually works.
- Tracking and measurement: Top AI SEO experts track brand mentions and citations inside AI-generated outputs, not just traditional search results rankings.
- Content quality standards: AI platforms cite authoritative, well-structured content. Look for agencies that prioritize depth, accuracy, and E-E-A-T signals over content volume.
- Integration with broader strategy: Online visibility does not exist in a vacuum. The best agencies connect GEO to your full marketing picture, including technical expertise in SEO, digital PR, and conversion.
- Proven client results: Ask for case studies with specific outcomes tied to AI visibility, qualified lead generation, and organic traffic growth, not just vanity metrics.
