LLM SEO is gaining traction as businesses look to improve their visibility in AI search platforms like ChatGPT, Perplexity, and Gemini. As demand grows, more agencies are offering LLM SEO, Generative Engine Optimization (GEO), and AI search optimization services.
The challenge is finding the right one. Most “best LLM SEO agencies” lists are promotional, biased, or based on little research. They rarely explain why an agency is included or how it compares to the alternatives.
To make your search easier, we evaluated agencies using publicly available data, including Google reviews, Trustpilot ratings, Reddit and Quora discussions, case studies, and their service offerings.
This list highlights the best LLM SEO agencies for 2026, giving you a research-backed starting point to compare your options without spending hours doing it yourself.
Top LLM SEO Agencies to Improve Visibility in ChatGPT, Perplexity & Gemini
As you’ll notice, Contentsify is also included in this list. We recognize that we’re evaluating our own agency, so we’ve applied the same criteria used for every other agency. Its inclusion is based on the LLM SEO work we’ve delivered, client results, and publicly available feedback, not simply because it’s our company.
With that in mind, here’s a closer look at each LLM SEO agency:
1. Contensify
At Contensify, we help B2B SaaS companies improve their visibility across traditional and AI-powered search through SEO, LLM SEO, GEO, and content marketing. Backed by over a decade of experience in SaaS search, we focus on building a qualified pipeline by making brands easier to discover and recommend throughout the buyer journey.
We don’t treat LLM SEO as a separate service. Instead, we integrate it with technical SEO, content strategy, authority building, and digital PR to create a search strategy that performs across both search engines and AI platforms like ChatGPT, Perplexity, Gemini, and Google AI Overviews.
How We Approach LLM SEO
We begin by auditing how your brand appears across AI search platforms, where competitors are being cited, and where opportunities exist. From there, we optimize content for AI retrieval, strengthen technical foundations, implement structured data, build authority signals, and continuously test AI responses to improve visibility over time.
Why We Stand Out
- Over a decade of experience helping B2B SaaS companies grow through search.
- LLM SEO is fully integrated with SEO, content marketing, technical optimization, and digital PR.
- We focus on building long-term AI visibility instead of relying on short-term tactics.
- Our strategy evolves continuously through AI prompt testing, monitoring, and refinement.
LLM SEO works best when it’s part of a broader search strategy, not a standalone tactic. If that’s the approach you’re looking for, schedule a discovery call with our team to see how we can help.
2. Skale
Skale is a London, England-based LLM SEO agency focused on driving pipeline, qualified signups, and revenue through organic search. Its services combine SEO, GEO, technical optimization, and content to help software companies improve visibility across both search engines and AI platforms.
Its strategy focuses on strengthening a brand’s citation footprint across trusted third-party sources. Skale identifies the publishers influencing AI-generated answers, secures relevant brand mentions through targeted outreach, and tracks visibility across ChatGPT, Perplexity, Claude, Gemini, and Google AI Overviews.
3. Stratabeat
Stratabeat is a B2B SaaS and tech-focused LLM SEO agency that combines GEO, SEO, content strategy, CRO, and authority building to improve AI search visibility. Unlike many agencies, it starts with in-depth audience research, including buyer interviews, CRM insights, and sales call analysis, to build content strategies grounded in real customer behavior.
Its LLM SEO approach prioritizes LLM retrievability, structured data, entity optimization, and conversational search. Stratabeat also limits each strategist to just 2-4 accounts, enabling a more hands-on engagement. The agency is a strong fit for B2B companies looking for a research-led strategy rather than a template-driven SEO program.
4. Animalz
Animalz is an LLM SEO agency that helps B2B SaaS companies improve their visibility across AI search platforms like ChatGPT, Perplexity, Gemini, and Google AI Overviews. Its services focus on increasing brand mentions and citations through AI visibility audits, content optimization, citation outreach, and ongoing performance tracking.
A key strength of Animalz is its structured LLM SEO offering. Rather than bundling services under a single package, it clearly defines each deliverable, from AI audits and content refreshes to Reddit engagement and citation building, making it easier for businesses to understand how their AI search visibility is being improved.
5. NoGood
NoGood is a New York-based LLM SEO agency that helps brands improve their visibility across ChatGPT, Gemini, Perplexity, Claude, and other AI search platforms. Its AEO services combine AI visibility audits, content optimization, technical SEO, citation analysis, and authority building.
A key differentiator is Goodie, NoGood’s proprietary AEO platform for tracking AI visibility, optimizing content, and monitoring citations across LLMs. This gives brands a more data-driven way to measure and improve their presence in AI search.
6. Spicy Margarita
Spicy Margarita is a London-based LLM SEO agency that helps B2B companies improve their visibility across AI search platforms. Its services focus on Answer Engine Optimization (AEO), AI citation placements, brand visibility, and content creation, helping brands become part of AI-generated answers rather than just search results.
Its LLM SEO strategy emphasizes building a strong citation footprint through trusted publications, listicles, Reddit, YouTube, and other sources AI models rely on. Alongside AI-focused content and brand monitoring, the agency helps businesses improve how they’re represented across LLMs.
7. Trailblazer
Trailblazer is an LLM SEO agency that helps brands improve visibility across ChatGPT, Perplexity, Gemini, Claude, and other AI search platforms. Its services combine SEO, LLM-optimized content, backlinks, digital PR, Reddit marketing, and brand mentions to strengthen AI search visibility.
The agency takes a content-first approach to LLM SEO, supported by off-page signals that influence AI-generated answers. Alongside high-volume content production, Trailblazer focuses on building authority through backlinks, Reddit discussions, and digital PR.
8. DerivateX
DerivateX is a B2B SaaS-focused LLM SEO agency that helps brands increase visibility across ChatGPT, Perplexity, Gemini, and Claude. Its proprietary Citation Engineering methodology combines content, entity optimization, and authority building to improve AI citations while connecting them to demos, pipeline, and revenue.
Its LLM SEO strategy focuses on intentional AI visibility rather than relying on organic mentions. By combining AI visibility audits, citation engineering, digital PR, structured data, and attribution tracking, DerivateX helps SaaS companies turn AI search into a measurable growth channel.
9. Optimist
Optimist is a B2B SaaS-focused LLM SEO agency that combines SEO and AEO through its proprietary CORE framework. Rather than treating AI search as a separate channel, it integrates AI visibility with content, authority building, and pipeline-focused SEO.
Its LLM SEO strategy includes AI visibility audits, content optimization, entity improvements, and authority building, with performance measured against pipeline and revenue rather than rankings alone. This makes Optimist a strong fit for SaaS companies looking to connect AI search visibility with business growth.
10. Embarque
Embarque is a London-based LLM SEO agency that helps SaaS companies improve visibility across both traditional and AI search. Alongside SEO, it offers dedicated LLM SEO, AEO, and programmatic SEO services, with transparent pricing, flexible monthly plans, and no long-term contracts.
Its LLM SEO approach combines AI-optimized content, citation building, and authority signals to improve visibility in AI-generated answers. Embarque also supports Reddit marketing and programmatic SEO to strengthen brand mentions across AI search while keeping campaigns closely tied to measurable business growth.
Note: While these agencies offer strong LLM SEO capabilities, hiring one isn’t always the right move. The next step is understanding whether your business actually needs an LLM SEO agency and how to evaluate the right partner.
Do You Need an LLM SEO Agency?
An LLM SEO agency is worth considering if:
- Your website ranks on Google but rarely appears in ChatGPT, Perplexity, Gemini, or AI Overviews.
- You have strong content but aren’t earning AI citations or brand mentions.
- You need help building off-site authority, citations, and entity signals, not just optimizing pages.
- You don’t have the time or tools to monitor AI visibility across multiple platforms.
If your website still has fundamental SEO issues, such as poor crawlability, thin content, or little domain authority, fix those first. LLM SEO builds on a strong SEO foundation rather than replacing it.
For businesses that already have a solid SEO foundation, the right LLM SEO agency can help accelerate AI visibility. Here’s what to look for before hiring one.
How to choose the right LLM SEO agency
Before signing with an LLM SEO agency, ask these questions:
- How do you improve AI visibility? Look for a strategy covering content, citations, authority, and technical SEO.
- How do you earn AI citations? They should mention third-party publications, reviews, digital PR, or trusted industry sources.
- Can you show relevant case studies? Ask for results from businesses similar to yours.
- How do you measure success? The focus should be on AI visibility, leads, pipeline, or revenue.
- What will I see in your reports? Expect AI visibility, citations, brand mentions, and business impact, not completed tasks.
Looking for an LLM SEO agency that delivers more than rankings? At Contensify, we help B2B SaaS brands improve their visibility across AI search and Google through proven strategies, proprietary frameworks, and a team of SEO specialists.
