Search doesn’t work the way it used to.
Humans now ask ChatGPT, Gemini, Perplexity, and Claude questions directly. Instead of 10 blue links, they get one written answer.
LLM SEO, also called GEO or AEO, is the work of getting your brand into that answer. A good agency helps you show up more often.
No one can promise a citation every single time. The AI decides that on its own.
But the right agency can tilt the odds in your favor. Here are 5 agencies doing this well right now.
Quick Summary
These are our top 3 picks from the list.
| Agency | Best for | AI search focus |
| MonsterClaw | Full-stack SEO + AI visibility, one team | ChatGPT, Gemini, Perplexity, AI Overviews |
| iPullRank | Enterprise, technically complex sites | Relevance Engineering across major AI platforms |
| Omnius | SaaS & fintech specifically | ChatGPT, Gemini, Claude, Perplexity (via AtomicAGI) |
How We Selected 5 Best LLM SEO Agencies
Proven SEO Foundation
Strong SEO fundamentals are the bedrock of LLM visibility.
For this, an agency must know how to fix a website’s bones. That involves technical SEO, clean crawlability, proper indexing, strong site architecture, solid internal linking, and useful content. We evaluated each agency’s approach to each of these.
AI answer engines lean heavily on the same search index Google uses to find trustworthy pages. So, an agency with weak SEO instincts may fall behind in the AI visibility race.
AI Search Optimization
This is different from regular SEO.
We looked for agencies that actually spent real time testing how ChatGPT, Gemini, Perplexity, Claude, and Google AI Overviews pick their answers.
Each of these AI tools works a little differently. One may prefer short lists. Another may prefer long explanations.
An agency that has tested this hands-on will know what actually gets picked up.
Entity & Brand Authority
AI systems need to know who you are and what you do.
Entity optimization ensures your brand, people, products, and services are clearly defined and connected.
This involves schema markup, consistent information across the web, and signals that build trust.
Content Built For Retrieval & Citation
Not every piece of content gets picked up by AI.
Content that gets cited usually answers the question clearly near the top. It’s broken into short sections, with real comparisons, statistics, definitions, expert insights, and original research.
We picked those LLM SEO agencies that write articles this way.
Off-Site Citation Building
Your website is only one piece of the puzzle.
AI tools also look at what other sites say about you. They may reference industry publications, editorial websites, comparison platforms, and communities.
We evaluated several agencies and selected the one that actively earns these mentions. Without them, AI tools have fewer reasons to trust or mention you, even over a weaker competitor.
AI Visibility Measurement
You can’t improve what you don’t track.
We opted for agencies that use proper AI visibility monitoring tools to track citations, sentiment, share of voice, and business outcomes.
Generic claims like “we improved AI visibility” don’t mean much without proof.
Tracking such metrics shows what’s improving and whether AI visibility drives real results.
Evidence of Execution
This one is simple: has the agency actually done this before?
We assessed factors like real case studies, a clear step-by-step process, and actual client history. Any agency can claim skill. Fewer can show real before-and-after numbers to prove it.

1. MonsterClaw | Best Overall LLM SEO Agency
Why MonsterClaw Ranked #1
MonsterClaw didn’t treat AI visibility as a side project.
It built AI work directly into an SEO operation running for over 15 years in digital marketing/SEO. We’ve worked with 500+ clients across SEO, content, and technical services. Instead of picking one lane, our site openly targets Google, ChatGPT, and Gemini together.
The numbers back this up. MonsterClaw has generated $47M+ for clients and driven 100M+ impressions. Some client sites are now cited hundreds of times across AI tools.
What earns MonsterClaw the top spot isn’t one single tactic. It’s-
- Technical SEO
- Content strategy
- Authority building
- Entity optimization
- Structured data/schema
- Digital PR/brand citations
- AI citation tracking
- ChatGPT visibility
- Gemini visibility
- Perplexity visibility
- Google AI search visibility
All sit under one roof, run by a team that already knows your site.
MonsterClaw’s Approach to LLM SEO
At MonsterClaw, we run a fairly straightforward process:
AI Visibility Audit > Query Research > Entity Optimization > Content Architecture > Citation-Worthy Content > Authority Mentions > Technical Optimization > AI Visibility Tracking.
The process starts by checking where your brand shows up, and where competitors show up instead. Then, we dig into the real questions your buyers ask AI tools. From there, we sharpen your content, entity signals, SEO, and structured data, and earn mentions from sites AI already trusts. Finally, we track visibility over time.
This isn’t a one-size-fits-all checklist. We tailor our approach to each client’s industry, audience, and goals. But the core principle stays the same: make your brand too clear and useful for AI to skip.

Best For

- Enterprise
- Brands needing both Google SEO and AI visibility
What Makes MonsterClaw Stand Out As An LLM SEO Agency?
- One team handles everything. You skip hiring a separate SEO agency and GEO consultant. Everything runs under one roof.
- Real, published citation numbers. Case studies show actual AI Citation counts on real pages, not vague claims.
- Works in tricky niches too. The Vapedeal case study shows real AI visibility in a heavily restricted industry with no paid ads allowed.
- 15 years of SEO groundwork. AI tools still lean on the same search index Google trusts. That history gives MonsterClaw a head start.
- Built for growing brands and big brands alike. No separate “AI package” needed later.

2. iPullRank | Best for Enterprise LLM SEO
iPullRank calls itself an AI search and content marketing agency.
It focuses on Relevance Engineering, restructuring content so AI models can retrieve it more easily. The agency has reported more than $5B in organic search results across client work.
It also built its own tools for testing passage-level relevance. Its work spans technical SEO, entity signals, and content engineering for AI discovery.
Best For
- Large enterprises
- Technically complex websites.
Potential Drawback
- This depth suits bigger companies more than a small team wanting a quick GEO push.
3. Omnius | Best LLM SEO Agency for SaaS & Fintech
Omnius works only with SaaS, fintech, and AI companies.
Its biggest edge is a proprietary tracking tool called AtomicAGI, built in-house starting in 2024.
The agency runs AI visibility audits and optimizes for ChatGPT, Gemini, Claude, and Perplexity. It treats SEO and GEO as one connected job. Not two separate services.
Omnius even ran this playbook on its own site. It grew AI search clicks by 138% and tracked 193 citations across ChatGPT, Perplexity, Claude, and Gemini.
Best For
- SaaS
- Fintech
- AI
- Other tech companies
Potential Drawback
- Its narrow focus means companies outside these industries may not be the best fit.
4. Animalz | Best for Content-Led LLM SEO
Animalz built its name on content marketing for B2B SaaS brands.
The agency carried that strength into its Answer Engine Optimization, or AEO, service. This covers AI visibility audits, content refreshes, new content, and citation outreach.
It also includes Reddit and community engagement, since AI models pull from those too.
That same content engine took Amplitude’s organic traffic from roughly 7,000 to 150,000+ monthly visits across a decade-long partnership.
If your brand already leans on strong content, this agency points that content toward AI visibility.
Best For
- B2B SaaS companies with big content libraries or a thought-leadership focus.
Potential Drawback
- Its strength is content, not deep, enterprise-level technical SEO.
5. Breaking B2B | Best for Revenue-Focused B2B LLM SEO
Breaking B2B ties LLM visibility to commercial, bottom-of-funnel searches.
These are the queries that actually lead to a booked demo. Their approach also targets ChatGPT and Gemini citations, citation-source engineering, and query-specific content. Plus, they measure AI referral traffic and demo conversions.
The agency reported a 91% increase in AI-search visitors for client Proposify. That came with a 115% lift in demos.
It also helped RB2B rank for a competitive query in both Google and ChatGPT at once. Everything here is built around pipeline.
Best For
- B2B SaaS companies focused on demos and sales pipeline.
Potential Drawback
- This commercial focus suits fewer e-commerce, local, or broad enterprise programs.
What Does an LLM SEO Agency Actually Do?
A good LLM SEO agency mixes research, content, technical work, and tracking. It helps your brand get mentioned in AI-generated answers.
Prompt & Query Research
Figuring out the actual questions buyers type into ChatGPT and Gemini. Once you know the real phrasing, you can build content that answers it directly.
AI Visibility Benchmarking
Checking where your brand currently shows up, or doesn’t, compared to competitors. That way, you have a starting line to measure progress against.
Entity Optimization
Making sure AI systems correctly understand who you are. This includes your products, your people, your services, and how they all connect. Confused entities lead to missing citations.
Content Optimization
Rebuilding pages around extractable answers, comparisons, real statistics, definitions, and expert commentary. This is the format AI models tend to lift.
Technical SEO
None of the above matters if crawlers and retrieval systems can’t reach your content. Clean site architecture keeps your best pages accessible.
Structured Data
To add the right schema. For instance, Organization, Product, Service, Person, Article, FAQ, and so on. This gives AI systems a shortcut to understanding your content correctly.
Digital PR & Citation Building
Earning mentions from publications and sites that AI models already trust. This helps build outside validation your own website can’t provide alone.
AI Search Tracking
Ongoing monitoring of citations, mentions, sentiment, competitor share of voice, referral traffic, leads, and sales. It tells you whether all of the above is actually working.
LLM SEO vs Traditional SEO
| Traditional SEO | LLM SEO |
| Keyword rankings | Prompt visibility |
| SERP position | Brand recommendations |
| Backlinks | Citation/source authority |
| Organic clicks | AI mentions + referrals |
| Search snippets | Generated answers |
| Keyword share | AI share of voice |
| Google-focused | ChatGPT, Gemini, Perplexity, Claude + Google |
How to Choose an LLM SEO Agency?
Proven SEO & AI Experience
Check whether the agency understands both traditional SEO and AI search. This helps ensure your strategy covers the basics while adapting to how AI platforms select sources.
A team that lacks either side may miss the signals supporting long-term AI visibility.
Citation-Focused Content
Ask for examples of content that earned real AI citations.
It helps you understand if their content performs well. Publishing more pages means little if the content never appears in relevant AI answers.
Clear Visibility Tracking
Ask how the agency tracks citations, mentions, and visibility changes.
Regular reporting helps you see whether the work is improving your brand’s AI presence.
Integrated SEO Strategy
Pick an agency that connects LLM SEO with technical SEO, content, and authority building. A combined approach reduces gaps between different search strategies.
Buyer Prompt Research
Ask how the agency finds the prompts your potential customers actually use. Research reduces guesswork and helps focus your budget on relevant opportunities.
Proven Client Results
Request case studies with specific numbers and timelines. Real results give you a clearer picture of what the agency can actually deliver.

What Does LLM SEO Cost?
| Pricing Factor | Typical Cost / Impact |
| Audit / Project | $5,000-$15,000 for a one-time AI visibility audit and recommendations |
| Monthly Retainer | $5,000-$30,000+ per month, depending on scope |
| Enterprise Engagement | Custom pricing, often $30,000+ per month |
| Content Volume | More content requirements generally mean higher costs |
| Citation / PR Requirements | Building authority and earning citations requires additional work and investment |
| Number of AI Engines Tracked | Tracking more AI engines increases the cost |
| Website Size | Larger websites typically require more analysis and ongoing work |
Most digital marketing agencies charge between $5,000 and $30,000+ per month for a full-service LLM SEO program. The cost varies by agency and job size. It shifts with content volume, PR work, how many AI engines you track, and your website’s size.
Can an Agency Guarantee ChatGPT or Gemini Citations?
No. No agency (and no website) controls which sources an AI model picks. A good agency can only improve the odds by strengthening-
- Search visibility
- Entity clarity
- Content relevance
- Citation authority
- Brand mentions
- Structured information
- Retrieval accessibility
- Third-party validation
Anyone promising a guaranteed citation is overselling something no one can fully control.
