Top 8 LLM SEO agencies for B2B (2026 Guide).
The best LLM SEO agencies for B2B in 2026 treat citation in ChatGPT, Gemini and the other AI answer engines as a measurable outcome, not a slide added to an existing SEO deck. Some are narrow specialists built around a single 90-day programme; others are broader growth or content agencies that added LLM SEO as a service line once clients started asking for it. Below are eight worth shortlisting, ranked on who they target, what they publish about price, and which AI engines they actually name.
We publish this list and SourceRank AI is our own service; the other seven are ranked on the criteria below, verified against each provider's own site on the day this was written.

What is LLM SEO, and how is it different from AEO or GEO?
LLM SEO is the practice of optimising a company's site and off-site presence so large language models such as ChatGPT, Gemini and Claude cite it when answering a buyer's question, rather than optimising for a ranked results page. In practice every agency on this list uses LLM SEO, AEO (Answer Engine Optimization) and GEO (Generative Engine Optimization) to describe close to the same discipline: entity clarity, structured data, answer-ready content and the off-site citations models draw on. The full breakdown of where the terms genuinely diverge is in the LLM SEO glossary entry; for a buyer comparing agencies, the label on the service page matters less than which engines it names and what it actually measures.
How we chose
Every provider on this list had to clear three bars: it names LLM SEO, GEO or AI search visibility as a real service, not a single blog post mentioning ChatGPT; it is verifiable against its own site as of this run; and it is not a current SourceRank AI client or partner. Within that set we weighed:
- 1. A named LLM SEO or GEO offer, distinct from a general SEO retainer with an AI slide added.
- 2. Which AI engines are named explicitly. "AI search" in general is worth less than a stated list such as ChatGPT, Perplexity, Gemini and Claude.
- 3. Pricing transparency, because a published floor lets a buyer qualify itself before a scoping call.
- 4. Buyer fit and stated exclusions. Several of these agencies explicitly turn away company types outside their brief, which is a useful signal of focus.
- 5. Verifiable B2B or B2B SaaS specialism, checked against each firm's own client list and case material.
The 8 best LLM SEO agencies for B2B
1. SourceRank AI
Best for: a B2B company that wants LLM SEO delivered as a done-for-you service, starting from a fixed-price, fixed-scope audit rather than an open-ended scoping call.
SourceRank AI is a done-for-you Answer Engine Optimization service, not software a client runs alone. It measures how often ChatGPT, Gemini, Microsoft Copilot, Google AI Mode and Google AI Overviews cite a company today (it does not measure Perplexity), diagnoses why named competitors get cited instead, then does the on-site structure, schema and off-site citation work to close the gap. The AI Visibility Audit is $497 one-time; ongoing plans run $997, $1,700 or $2,500 a month depending on scope. See how it works or book a call to scope one.
2. Rock the Rankings
Best for: a Series A-C B2B SaaS company, roughly $2m to $100m ARR, that wants a fixed-price diagnostic before committing to ongoing work.
Rock the Rankings runs a 90-Day AI Search Program combining GEO, SEO, content and link building into one track, targeting ChatGPT, Claude, Gemini, Perplexity and Google's AI box results. It states plainly that pre-seed companies, B2C apps, DTC ecommerce and enterprise consulting firms are not a fit. Pricing is published in three tiers: a $15,000 one-time AI Search Sprint, strategy and consulting from $5,000 a month, and a done-for-you retainer from $8,500 a month.
3. Breaking B2B
Best for: a B2B or SaaS team that wants LLM SEO content weighted toward bottom-of-funnel pages, comparisons, alternatives and citation tracking, run by senior staff throughout.
Breaking B2B serves B2B and SaaS companies exclusively, across healthtech, martech, fintech, financial services, logistics and construction, and runs a six-step process: audit current citations, research buyer prompts, build answer formats, fix search fundamentals, chase brand mentions, and track citations monthly. Plans start at $4,000 a month, with fast-growth programmes averaging $7,000 or more.
4. DerivateX
Best for: a $5m-$50m ARR B2B SaaS company that wants every LLM SEO deliverable tied explicitly to pipeline contribution rather than traffic or ranking dashboards.
DerivateX combines organic SEO with generative engine optimisation across ChatGPT, Perplexity, Gemini and Claude, and only takes B2B SaaS companies past product-market fit; it explicitly declines ecommerce, local services and B2C work. Three monthly retainer tiers are published: $5,000, $8,000 and $12,000, plus a standalone $3,500 diagnostic audit and a separate citation media budget of $1,000 to $3,000 a month.
5. OMNIUS
Best for: a SaaS, fintech or AI company that wants LLM SEO bundled with entity and Knowledge Graph work, plus a proprietary tracking tool.
OMNIUS works exclusively with SaaS, fintech and AI companies, with clients including Payoneer and BigCommerce named on its site, and covers GEO, AEO, entity SEO and AI search tracking through its own AtomicAGI tool, targeting ChatGPT, Perplexity, Claude, Gemini, DeepSeek and Google AI Overviews. It is headquartered in London, with offices in Dubai and Belgrade. Pricing is not published.
6. Embarque
Best for: a B2B company with a long, technical sales cycle that wants citation-ready content plus a visibility tracking dashboard rather than a one-off report.
Embarque specialises in "complex products with long sales cycles and technical audiences who use AI for research," spanning B2B SaaS, professional services, fintech and HR tech, and names 200-plus clients and 27 published case studies. Its service covers AI search audits, citation-ready content and custom visibility dashboards across ChatGPT, Perplexity, Claude and Google AI Mode. Pricing is not published.
7. Contensify
Best for: a B2B SaaS company that wants LLM SEO folded into an existing SEO and digital PR programme rather than bought as a separate specialism.
Contensify frames its offer as SEO, LLM SEO, GEO and content marketing run as one integrated practice, built on what it describes as over a decade of SaaS search experience, and operates from Delhi/NCR, Bangalore, Dubai, Singapore and the UK. Pricing is not published on the site.
8. Flow Agency
Best for: a B2B startup or service provider that wants LLM SEO paired with paid LLM advertising under one team.
Flow Agency has worked with more than 100 B2B startups and service providers, building bespoke LLM optimisation strategies alongside LLM advertising, traditional B2B SEO, paid media and link building, targeting Google AI Overviews, ChatGPT Search and Perplexity. The team is described as remote and distributed, with no physical headquarters published. Pricing is not published; prospects are asked to submit a custom brief.
How much does LLM SEO cost in 2026?
Published pricing on this list ranges from a $497 one-time audit (SourceRank AI) to a $15,000 one-time diagnostic sprint (Rock the Rankings), with monthly retainers spanning $4,000 (Breaking B2B) to $12,000 (DerivateX's top tier) among the providers that publish a figure at all; OMNIUS, Embarque, Contensify and Flow Agency all route pricing through a scoping call. The full AEO cost guide covers the wider retainer market in more depth, including what typically changes the price: the number of engines and prompts tracked, whether off-site citation building is included, and whether the audit is standalone or the first phase of a longer engagement.
How do you choose between these eight LLM SEO agencies?
- 1. Confirm the engine list, not just "AI search." ChatGPT, Gemini, Microsoft Copilot, Google AI Mode and Google AI Overviews behave differently from each other and from Perplexity; ask which of these a provider actually tests and reports on.
- 2. Check whether pricing is published before you book a call. SourceRank AI, Rock the Rankings, Breaking B2B and DerivateX all publish a starting figure; the other four require a scoping conversation to learn the number.
- 3. Match the provider's stated buyer profile to your own stage and revenue. DerivateX and Rock the Rankings both name specific ARR or funding-stage ranges and explicitly decline companies outside them.
- 4. Decide whether you want LLM SEO as its own engagement or one line inside a broader retainer. OMNIUS, Embarque, Contensify and Flow Agency all bundle it with other services; SourceRank AI, Rock the Rankings, Breaking B2B and DerivateX sell it as the primary product.
- 5. Get an independent baseline before the first call. Get your free AI visibility score to see how your site currently reads to AI crawlers and structured data checks, then use it to brief any provider on this list against the same starting point. The guide to choosing an AEO agency covers the rest of the questions to ask once you are comparing quotes.
Key Terms Glossary
Frequently asked questions
What is LLM SEO?
LLM SEO is the practice of structuring a company's content, entity data and off-site citations so large language models such as ChatGPT and Gemini name it directly in an answer, distinct from traditional SEO's focus on ranking a page in a results list. See the full definition for how it is measured.
Is LLM SEO the same thing as AEO or GEO?
For nearly all practical purposes, yes. SourceRank AI and every agency on this list use LLM SEO, AEO and GEO to describe close to the same work: entity clarity, structured data, answer-ready content and the off-site signals models draw citations from. The label an agency uses tends to reflect its background (SEO agencies favour GEO, newer specialists favour LLM SEO) more than a real difference in the service.
How much does an LLM SEO agency cost in 2026?
Published prices on this list run from a $497 one-time audit up to $12,000 a month for a full retainer tier, with four of the eight providers routing pricing through a scoping call instead. See the AEO cost guide for the wider market.
Which AI engines should an LLM SEO agency actually target?
At minimum ChatGPT, Google Gemini and Microsoft Copilot, since those are the engines most B2B buyers already use for vendor research; Google AI Mode and Google AI Overviews add coverage inside ordinary search. SourceRank AI measures all five; it does not measure Perplexity, which several agencies on this list do include.
Do any of these agencies work with companies outside the United States?
Yes. SourceRank AI is based in Aarhus, Denmark and works with clients worldwide; OMNIUS is headquartered in London with offices in Dubai and Belgrade; Contensify operates from India, Dubai, Singapore and the UK. The rest are US-based or remote; confirm international coverage directly before signing.
Should I hire an LLM SEO agency or run it in-house?
Hire an agency if you want a measured citation rate and a dedicated fix without building the tracking and content workflow yourself; keep it in-house only if you already have someone who can own prompt tracking, schema implementation and off-site citation outreach as an ongoing job, not a side project. Most B2B teams asking this question have neither the tooling nor the time, which is why every provider on this list exists.
How do I compare these agencies against my own AI visibility today?
Start with a baseline rather than any agency's pitch. Get your free AI visibility score to see how your site currently reads to AI crawlers and structured data checks, then brief any provider on this list, SourceRank AI included, against that same starting point rather than the one each one leads with.
How long does LLM SEO take to show results?
Most providers on this list, SourceRank AI included, frame the first meaningful checkpoint around 90 days: enough time for schema and content fixes to be crawled and reflected in a new round of prompt testing, though citation gains for well-established competitors can take longer. Ask any agency you are considering what its 90-day plan actually commits to before signing.
