8 Best AI SEO Agencies That Cover GEO and Traditional Search

Summary:

• Most "AI SEO" agencies are just rebranding old services and lack true Generative Engine Optimization (GEO) skills needed for platforms like ChatGPT, which reaches 800 million weekly users.

• A modern strategy requires mastering both traditional SEO (ranking on Google) and GEO (getting cited by AI models).

• This article evaluates the top 8 agencies that excel in both worlds, providing key questions to ask before hiring one.

• For B2B SaaS, Synscribe offers a unique advantage by combining a proprietary AI platform with a full-stack engineering team for direct implementation.

If you've been searching for the best AI SEO agencies that do both GEO and traditional SEO, you've probably noticed something frustrating: almost every agency out there now claims to do "AI SEO." But dig one layer deeper and the picture gets bleak fast.

Most of them are doing the exact same thing they were doing three years ago — producing blog content and building backlinks — just with a fresh coat of AI paint. As one marketer on Reddit put it bluntly: "Everyone promises 'AI magic' with no real proof."

Here's what these agencies are typically missing:

• LLM crawler optimization — ensuring AI models can actually access, parse, and trust your content

• AI Share of Voice monitoring — tracking how visible your brand is in AI-generated answers, not just Google rankings

• Source citation monitoring — knowing whether ChatGPT, Perplexity, or Google AI Overviews are actually citing you as a source

This gap matters more than ever. According to Search Engine Land, ChatGPT now reaches 800 million weekly users, and AI Overviews appear in 16% of all searches. If your agency can't tell you how visible you are in those results, they're optimizing for a search landscape that's already shifting beneath your feet.

A true AI SEO agency has to master two distinct disciplines simultaneously:

1. Traditional SEO — technical foundations, content strategy, link building, and rankings on Google

2. Generative Engine Optimization (GEO) — optimizing your brand and content to be discovered, trusted, and cited by AI models

The 8 Best AI SEO Agencies That Do Both GEO and Traditional SEO

To cut through the hype, we've filtered this list by specific, hard-to-fake capabilities: schema and llms.txt implementation, AI query fan-out analysis, source citation monitoring, and traditional ranking performance. Here are our picks for the best AI SEO agencies that do both GEO and traditional SEO.

1. Synscribe

Best for: B2B SaaS companies that want to dominate both Google rankings and AI-powered search from a single, unified team

Synscribe is built differently from the ground up. It's a product + agency hybrid — meaning clients don't just get a team of consultants; they get access to a proprietary AI platform and a full-stack engineering team that executes end-to-end. While most agencies hand you a strategy deck and wish you luck, Synscribe's engineers push code directly to your repository.

GEO Capabilities

What separates Synscribe in the GEO space is the depth and specificity of its stack:

• SEO & LLM platform: The only unified platform that tracks keyword rankings across Google and AI engines (ChatGPT, Perplexity, Claude) from a single dashboard. You get real-time AI Share of Voice monitoring alongside your traditional SERP rankings — no more piecing together data from five different tools.

• Source Citation Monitoring: Synscribe actively tracks when and where your brand is cited in AI-generated answers, giving you a measurable, concrete metric for GEO performance.

• LLM Content Scoring & Rewriting: Content is analyzed and rewritten to maximize "extractability" — the likelihood that an AI model will pull from it when answering a relevant query.

• AI Crawler Optimization + llms.txt: Implements the proposed llms.txt standard alongside schema markup to give AI models clear, structured signals about your content and authority.

• AI Query Fan-out Analysis: Maps the full universe of queries AI models use to explore a topic, ensuring your content covers the semantic surface area that matters.

Traditional SEO Execution

On the traditional SEO side, Synscribe uses AI to compress execution time without sacrificing quality:

• AI Content Writer (Autoblogger): Produces long-form, citation-backed articles grounded in real audience pain points surfaced through their Reddit Social Listening tool — not generic AI fluff.

• AI Landing Page Generator: Programmatically generates hundreds of conversion-optimized, SERP-intent-aligned landing pages exportable to any stack.

• AI Link Building: Automates prospect discovery, personalized outreach, and follow-up sequences to secure placements on pages that already rank for your target keywords.

Each client also gets a dedicated AI agent (built on OpenClaw) that autonomously executes 90% of the SEO workflow — keyword research, content production, link building, rank monitoring — while the human team handles strategy and quality oversight.

Notable differentiator: Synscribe is the only agency on this list where the same platform powering the client's AI search tracking is also running the execution. There's no gap between insight and action.

2. RZLT

Best for: B2B SaaS, AI, fintech, and Web3 companies that need AI-native marketing operations — not just SEO

RZLT is an AI-native marketing agency that has rebuilt its entire operation around AI workflows rather than bolting tools onto traditional processes. Their internal stack runs on Claude and n8n, with content production, SEO, AEO, and campaign automation all running through AI-first pipelines. That distinction matters: most agencies that claim "AI-powered" delivery are running the same playbooks with a ChatGPT prompt layered on top.

With 35+ people across 10 countries and 100+ clients served — including Telegram, Workato, and NEAR — RZLT operates more like an embedded growth function than a traditional agency waiting on a brief. Their core specializations span Go-to-Market Strategy, Performance Marketing, Demand Generation, ABM, and Content and Social Marketing, all powered by custom agentic workflows built in-house.

For companies that need AI infrastructure built into their marketing operations — not layered on as an afterthought — RZLT is worth evaluating alongside pure-play SEO agencies.

3. ResultFirst

Best for: Companies that want performance-based pricing tied to real results

ResultFirst operates on a pay-for-performance model, which forces accountability that most agencies avoid. Their AI capabilities are genuinely substantive: AI Keyword Forecasting, Content Intelligence Tools, and Intent-First Strategies that go beyond basic keyword targeting.

Their results speak clearly. They delivered impressive results, like a 753% LLM traffic increase for PlushBeds and a 22x spike in Copilot traffic for Codewars. If you're looking for one of the best AI SEO agencies that do both GEO and traditional SEO willing to put its compensation on the line, ResultFirst is worth a serious look.

4. TripleDart Digital

Best for: B2B SaaS companies looking for AI-driven content clustering

TripleDart builds custom AI agents that analyze site structure, product positioning, and audience behavior to design content architectures that compound over time. Their smart AI clustering approach delivered 3x organic growth for SurveySensum. If content architecture and topical authority are your primary gaps, TripleDart has shown real execution capability here.

5. Revenue Zen

Best for: Companies prioritizing GEO as a primary revenue channel

Revenue Zen has leaned into Generative Engine Optimization as a core specialization rather than an add-on service. Their end-to-end GEO strategy and execution framework covers brand visibility in AI-generated answers, not just traditional SERP rankings. They drove a 300% revenue increase for Incfile in 12 months — a result that reflects a focus on revenue outcomes over vanity metrics.

6. Omniscient Digital

Best for: Content-led SEO with a platform-agnostic visibility strategy

Omniscient Digital's "Surround SEO Strategy" is built around a simple premise: be everywhere your audience looks — whether that's Google, Reddit, YouTube, or the AI models trained on all of the above. This multiplatform approach is genuinely more aligned with how modern AI systems surface information than traditional single-channel SEO. They achieved 810% growth for Jasper, a particularly notable result given Jasper operates in the competitive AI writing space.

7. iPullRank

Best for: Enterprise companies with complex technical SEO challenges

iPullRank sits at the intersection of deep technical SEO and data science. Their relevance engineering approach — integrating structured data, semantic content models, and ML-informed audits — makes them one of the most technically rigorous agencies on this list. They've driven billions in client revenue and generated over 13 million visits for a single automotive publisher. For enterprise teams with complex technical debt and serious scale requirements, iPullRank is a strong candidate.

8. Siege Media

Best for: High-quality content production at scale with genuine editorial standards

Siege Media has built its reputation on one thing: content quality that doesn't erode under automation pressure. They use AI for efficiency and research, but they maintain editorial standards rigorous enough to produce content that earns links and ranks — not just fills a content calendar. Their 459% traffic value boost for Zoom reflects the compounding value of prioritizing quality over volume. For brands where E-E-A-T authority is a critical ranking signal, Siege Media's approach is worth considering.

What Separates Real GEO From the Hype

Before you sign with any of the best AI SEO agencies that do both GEO and traditional SEO, it's worth understanding what Generative Engine Optimization actually involves — because a lot of agencies use the term without knowing what it means in practice.

GEO is the practice of positioning your brand and content to be cited in AI-generated answers from platforms like Google AI Overviews, ChatGPT, and Perplexity. The goal isn't just ranking #1 — it's becoming a trusted source that AI models draw on when answering your audience's questions.

Here's how GEO differs from traditional SEO:

As one digital marketer noted in a Reddit thread: "If your content isn't well-structured or lacks clear context, AI engines will struggle to extract meaningful information from it." That's not a content quality problem — it's a structural one. And it requires a different kind of optimization.

The five foundational principles of GEO worth understanding:

1. Technical accessibility — AI can't cite what it can't crawl. Strong technical SEO is the entry ticket.

2. Entity clarity — Use schema.org structured data to define who you are, what you do, and what topics you're authoritative on.

3. Content extractability — Structure content in self-contained, citable paragraphs that answer specific questions directly.

4. Multiplatform presence — Build visibility on Reddit, YouTube, and industry forums where AI models source training data and real-time citations.

5. llms.txt implementation — A proposed standard (similar to robots.txt) that gives AI models a structured way to understand your most valuable, citable content.

Before You Sign: 5 Questions to Ask Any AI SEO Agency

Choosing the wrong agency is an expensive mistake — both financially and in lost time. Use these five questions to filter out the pretenders.

1. "How do you track visibility across both Google and AI engines like ChatGPT and Perplexity?"

A strong answer: "We use a unified platform that tracks keyword rankings, brand mentions, and source citations across both traditional SERPs and AI-generated answers. You get a single dashboard showing your AI Share of Voice alongside your Google rankings." (This is exactly what Synscribe's SEO & LLM platform delivers.) If an agency can't answer this specifically, they're flying blind on half the search landscape.

2. "What is your specific process for Generative Engine Optimization?"

A strong answer should cover at least four pillars: AI Crawler Optimization (including llms.txt and schema), Source Citation Monitoring, LLM Content Scoring, and AI Query Fan-out Analysis. Vague answers about "optimizing for AI" are a red flag.

3. "Can you implement technical changes directly, or will you only provide recommendations?"

Many agencies deliver audits and stop there. A strong answer: "We have a full-stack engineering team. We get access to your codebase and ship the fixes ourselves — Next.js, Webflow, WordPress, whatever you're on." Execution speed is the difference between months and days.

4. "How do you ensure AI-produced content meets E-E-A-T standards?"

The right answer starts before writing. A quality process surfaces real audience pain points (through social listening on platforms like Reddit), performs deep research, cites authoritative sources, and puts every piece through human review before publishing. If an agency just says "our AI writes great content," push harder.

5. "How do you tie your work back to revenue outcomes?"

Vanity metrics — impressions, overall traffic lifts, domain authority — aren't outcomes. The right answer focuses on bottom-of-funnel, high-intent keyword targeting, conversion-focused landing page performance, and a direct line from SEO and GEO activity to leads, sign-ups, or sales.

The Bottom Line

The search landscape has split into two parallel environments: the traditional web of blue links that Google ranks, and the emerging layer of AI-generated answers that an entirely different audience now relies on. Winning in 2025 and beyond means being visible in both.

Most agencies are optimizing for only one. The best AI SEO agencies that do both GEO and traditional SEO can show you exactly where you stand in both worlds — and have the platform and execution capability to move those numbers.

Use the questions above to separate the agencies with real dual-front capabilities from those just rebranding the same old content services.

And if you're looking for one of the best AI SEO agencies that do both GEO and traditional SEO, a partner that combines a proprietary AI platform with hands-on engineering execution to dominate both search worlds, talk with Synscribe.

Frequently Asked Questions

What is AI SEO?

AI SEO is an advanced approach to search engine optimization that incorporates strategies for both traditional search engines like Google and emerging AI-powered answer engines like ChatGPT and Perplexity. It involves using AI tools to enhance traditional SEO tasks and optimizing content to be discovered, understood, and cited by large language models (LLMs).

What is the difference between traditional SEO and Generative Engine Optimization (GEO)?

The primary difference lies in their goals and metrics. Traditional SEO aims to achieve high rankings on search engine results pages (SERPs), measured by clicks and traffic. Generative Engine Optimization (GEO) focuses on getting your brand and content cited as a source in AI-generated answers, measured by citations, brand mentions, and AI Share of Voice.

Why is Generative Engine Optimization (GEO) so important now?

GEO is crucial because user behavior is shifting towards AI-powered search. With millions of users turning to platforms like ChatGPT and Google AI Overviews for answers, being visible only in traditional search results is no longer enough. If your content isn't optimized to be a citable source for these AI engines, you risk losing visibility with a large and growing segment of your audience.

How can I measure the success of an AI SEO strategy?

Success in AI SEO is measured through a combination of traditional and new metrics. Key performance indicators (KPIs) include not only organic traffic and keyword rankings on Google but also your "AI Share of Voice," the frequency of brand mentions in AI answers, and the number of direct source citations your content receives from platforms like Perplexity and Google AI Overviews.

What is llms.txt and why does it matter?

llms.txt is a proposed standard, similar to robots.txt, designed to give AI models and crawlers clear instructions on how to interact with your website's content. It can signal which content is most valuable and citable, helping to guide AI engines to use your authoritative information when generating answers. Implementing it is a key technical aspect of advanced GEO.

How do I choose the right AI SEO agency for my business?

To choose the right AI SEO agency, you should look beyond promises of "AI magic" and ask specific questions about their capabilities. Inquire about how they track visibility across both Google and AI engines, their specific process for GEO, whether they can implement technical changes directly, and how they tie their efforts back to tangible revenue outcomes. A capable agency should be able to demonstrate expertise in both traditional SEO and GEO.
