Seven agencies build content specifically to get cited by ChatGPT, Perplexity, and Gemini. Google rankings are secondary to citation count. For B2B SaaS, the ones worth considering measure success in pipeline, not pageviews. LoudFace is ranked first on this list. We published it, so that bias is disclosed upfront.
LLM SEO and AEO are the same discipline. LLM SEO became the term buyers started searching in 2025 as ChatGPT and Perplexity took a real share of B2B research queries. AEO is the practitioner term for the same thing: structuring content to be extracted and cited by AI answer engines rather than just ranking in traditional blue-link results.
The agencies on this list do both, regardless of which term they use.
What separates genuine LLM SEO work from a rebrand: methodology, tooling, and measurement. Real work means citation monitoring (knowing when AI engines reference a brand and how), content formats AI engines prefer to extract from, and a feedback loop from citation data back to content decisions. Without those three components, an agency calling itself AEO-native is doing traditional SEO with new vocabulary.
This list is not neutral. LoudFace published it, and we rank ourselves first. Every other agency here has real methodology, real B2B SaaS clients, and public evidence of the work.
What to look for in an LLM SEO agency
Four things separate real methodology from marketing copy.
Citation monitoring software. Agencies that genuinely do LLM SEO track when and how AI engines cite their clients' content. Peec AI and Profound.ai are the tools used by agencies on this list. If an agency cannot tell you a client's current citation count on a tracked prompt set, they are not doing LLM SEO.
Specific content formats for extraction. Direct-answer blocks of 40-60 words, question-shaped H2s and H3s, FAQPage schema, entity-rich prose. Generic long-form content is not AEO-optimized content.
Prompt-level targeting. Keyword research and prompt research are different. LLM SEO starts by identifying which prompts a brand's buyers use in AI tools, then maps existing content against those prompts. Agencies that structure all work around keyword lists are not doing LLM SEO.
Pipeline measurement. Traffic is a vanity metric for B2B SaaS. Agencies worth engaging measure demo requests, free trial signups, and pipeline value attributed to organic.

1. LoudFace
Best for: Growth-stage B2B SaaS companies that want organic traffic tied to pipeline.
LoudFace is a B2B SaaS organic growth agency, stack-agnostic, with SEO and AEO built into every engagement as a unified discipline. Peec AI citation monitoring is part of the standard workflow, which means every content piece is tracked not just for Google rankings but for whether it appears in ChatGPT, Perplexity, and Gemini responses to the prompts clients' buyers actually use.
The methodology starts from citation gap analysis: which prompts your buyers use in AI tools where your brand has zero or losing coverage. Content is then structured for AI extraction, with direct-answer blocks, question-shaped headings, FAQ sections with schema markup, and entity-rich prose that AI engines can pull from cleanly. The feedback loop from citation data back to content decisions is built into the process.
Clients include Toku, CodeOp, and Zeiierman. See case studies, the SEO and AEO service page, and pricing.
Where LoudFace is not the best fit: Enterprise companies needing a global SEO footprint across dozens of domains, or companies whose buyers still do the majority of vendor research on Google with minimal AI tool usage.
2. Ten Speed
Best for: B2B companies that want execution that thinks and operates like an in-house team.
Ten Speed was founded by former in-house SaaS marketing leaders, which shapes how they scope work: in ARR-adjacent metrics like MRR, CAC, and pipeline rather than traffic reports. Their AEO capability page describes a concrete methodology: AI Brand Audits mapping how models currently reference the brand versus competitors, content formats AI prefers to extract from, competitive gap analysis by tracked prompt, and referral traffic tracking from AI tools.
Verified B2B SaaS clients include Bitly, TechSmith, Rasa, Metaplane, Spot AI, ProsperOps, and Visible. One published case study reports +78% organic visits/month, +90% traffic value, +98% keywords in top 10 (client name not disclosed). Custom pricing only, no long-term contracts mentioned in their public positioning.
Where Ten Speed is not the best fit: Companies that need high content volume at a lower per-piece cost. Ten Speed's value is strategic quality over throughput. No public pricing also means a conversation is required before you can assess whether the engagement fits your budget.
3. Discovered Labs
Best for: Teams that want to test LLM SEO before committing to a long-term retainer.
Discovered Labs runs AEO as a primary service, structured around a proprietary CITABLE framework for citation optimization. The tactic that genuinely differentiates them: Reddit as an AI citation strategy. They are one of very few agencies that explicitly frames Reddit engagement as influencing AI model recommendations, which is accurate and underused in the category. AI engines trained on web data pull Reddit threads heavily for conversational queries; brand mentions in relevant subreddits have a real effect on citation probability.
Month-to-month contracts are the other differentiator. Almost nobody else on this list offers that flexibility, which makes Discovered Labs a sensible first engagement for teams testing whether LLM SEO is worth the investment before committing to a longer retainer. Verified results: incident.io (+22% organic meetings), Sova Assessment (+167% organic demo requests), Passion.io (+29% ChatGPT referrals in one month). Approximate pricing: around €5,495+/month for the AEO service.
Where Discovered Labs is not the best fit: Companies with a well-established traditional SEO foundation that need to expand scale rather than test a new channel.
4. Omnius
Best for: SaaS and fintech companies that need technically explicit LLM optimization combined with programmatic content at scale.
Omnius has the most technically specific description of LLM optimization methodology among B2B-focused agencies on this list. Their GEO service explicitly covers LLMs.txt implementation, AI crawler optimization, zero-click query targeting, and citation monitoring via their proprietary AtomicAGI tool. Most agencies describe the output of LLM SEO (getting cited). Omnius describes the mechanism: the technical conditions that cause AI engines to pull from a specific source.
They also do programmatic SEO at scale, a distinct skill set from most content-first agencies. Verified results: TextCortex (0 to 2.7M organic visitors in 13 months), AuthoredUp (64% higher conversion rate), Entrepreneur First (0 to 60K monthly organic visits in 7 months). No public pricing.
Where Omnius is not the best fit: Companies primarily looking for thought-leadership content and editorial brand-building. For content-quality-over-volume programs, other agencies on this list are a better fit.
5. Omniscient Digital
Best for: Series B+ B2B SaaS companies with the budget for a premium agency and a mandate to own their category in both Google and AI search.
Omniscient Digital has the deepest public case study library of any B2B SaaS SEO agency on this list: Jasper (810% organic session growth, 400x product signups), Order.co (2,117% blog sessions, 39x conversions), GatherContent (867% organic blog sessions, 62% lead increase), Smartling ($3.7M pipeline generated). Drift, Loom, Amplitude, Asana, and Adobe are also on their client list. The track record is well-documented.
GEO was added as a service layer via a Peec AI partnership, making it an extension of a strong traditional SEO content strategy rather than an AEO-first rebuild. Starting from $10,000/month with a long-term partnership model.
Where Omniscient Digital is not the best fit: Early-stage or self-funded SaaS. The $10K floor excludes most pre-Series A companies. If AI-search visibility is the primary goal rather than a secondary layer on an established SEO program, more AEO-native agencies on this list are a more direct fit.
6. Perceptric
Best for: Series A SaaS or bootstrapped companies that want to start doing LLM SEO without committing to a $10,000+/month engagement.
Perceptric is the only agency on this list with fully transparent pricing tiers published on their website: Starter at $2,000/month, Growth at $4,200/month, Scale at $7,000/month. In a space where most competitors gate everything behind a sales call, published tiers let buyers self-qualify before the first conversation.
Their AI SEO methodology targets both Google rankings and LLM citation optimization. Verified case study: Momos ranking #1 on both Google and AI Overview for commercial terms. Other verified clients include Katalon, Zapier, ContentSquare, and Altexsoft.
Where Perceptric is not the best fit: Companies that need category-defining thought leadership or a premium editorial standard. The $2K-$7K tiers reflect the scope. For companies where original research and content quality matter as much as coverage, a higher-tier agency is a better investment.
7. Skale
Best for: Product-led growth SaaS that measures success in free trial signups and demo requests rather than pageview dashboards.
Skale positions as an AI search-first organic growth agency with a revenue-and-pipeline focus, targeting CAC payback under 12 months. Their case studies are the most outcome-oriented on this list: Rezi (+176% revenue), Holded (+450% monthly signups), Flodesk (+2,373% free trials), Attest (+520% demo requests). G2, Slite, Maze, and Bonsai are also in their portfolio.
AI Citation Outreach is a named tactic in their service offering, framing traditional link-building as citation influence for AI models. The connection is legitimate: domain authority signals that help Google rankings also influence which sources AI engines prefer to cite. No public pricing.
Where Skale is not the best fit: Companies that primarily need content velocity and AEO-structured long-form content rather than pipeline-attribution-focused SEO.
Frequently Asked Questions
What is LLM SEO and how is it different from traditional SEO?
LLM SEO optimizes content to appear in responses generated by AI-powered search tools: ChatGPT, Perplexity, Gemini, and Claude. Traditional SEO optimizes for blue-link rankings in Google's SERP. The technical difference: LLM SEO prioritizes structured, extractable content (direct-answer blocks, question-shaped headings, schema markup) over keyword density and backlink volume alone. For B2B SaaS companies in 2026, a meaningful share of buyer research happens via AI tools rather than Google searches, which makes both surfaces worth optimizing.
What is the difference between LLM SEO and AEO?
Effectively none. AEO (Answer Engine Optimization) was the practitioner term coined in 2023-2024 for optimizing content to be cited by AI answer engines. LLM SEO became the buyer-facing search term in 2025 as awareness of the category grew. The underlying discipline is the same. Agencies use both terms interchangeably. The relevant question is whether an agency has real methodology. What they call it does not matter.
How do I know if an agency actually does LLM SEO or just added a page about it?
Three indicators of genuine methodology: they use citation monitoring software to track when and how AI engines reference client brands (Peec AI, Profound.ai, or similar); they describe specific content formats they produce for AI extraction rather than just content that AI loves; they measure citation metrics alongside rankings. Agencies without these three elements are doing traditional SEO and calling it LLM SEO.
How long does it take to see results from LLM SEO?
AI citation results typically appear faster than Google rankings, but the timeline varies by how competitive the prompt space is. For a well-structured piece targeting an unclaimed prompt, citation can appear within days of indexing, since AI engines pull from a wider surface than Google's page 1. Brand-level citation authority, meaning consistent recommendations across many related prompts, compounds over 6-12 months. Google ranking changes generally take 3-6 months to materialize.
What does LLM SEO cost for B2B SaaS companies?
Public pricing is rare in this space. Perceptric publishes tiers from $2,000/month (Starter) to $7,000/month (Scale). Omniscient Digital starts at $10,000/month. Most agencies, including Ten Speed, Discovered Labs, Omnius, Skale, and LoudFace, price custom engagements after a discovery conversation. For Series A SaaS with budget constraints, Perceptric's published tiers are the clearest starting point. For Series B+ companies, $8,000-$15,000/month is a realistic range for a dedicated LLM SEO retainer with a specialist agency.
Can a B2B SaaS company do LLM SEO in-house?
Yes, but the tooling is the hard part. You need citation monitoring software to track whether AI engines are citing your content, an understanding of which prompts your buyers use in AI tools (different from traditional keyword research), and a content production process that outputs structured, extractable formats. For companies with an internal content team and someone who understands AEO structure, in-house execution is viable. Most companies that get there without an agency first built the strategy with one.
Which B2B SaaS companies benefit most from LLM SEO in 2026?
Categories where AI search is already eating meaningful share of buyer research: developer tools, security infrastructure, data and analytics platforms, HR tech, and fintech. Buyers in these categories are disproportionately comfortable researching in ChatGPT and Perplexity before visiting a vendor website. Companies selling to technical buyers see the fastest payoff from LLM SEO. If your buyers still find vendors primarily through Google and word-of-mouth referrals, traditional SEO remains the higher-ROI channel, though optimizing for AI search is still worth doing as a secondary layer.
