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.
How to evaluate an LLM SEO agency
Four criteria separate real LLM SEO methodology from rebranded traditional SEO. Each maps to a concrete signal in how the agency operates and sells.
| Criterion | Why it matters | Red flag |
|---|---|---|
| Citation monitoring software | An agency that cannot tell you a client's current citation count on a tracked prompt set in ChatGPT, Perplexity, and Gemini is not measuring LLM SEO. They are guessing. Peec AI and Profound.ai are the standard tools used by the agencies on this list. | "We track branded mentions and direct traffic" is not citation measurement. That is SEO 101 instrumentation with new vocabulary. |
| Content formats for AI extraction | Direct-answer blocks of 40 to 60 words, question-shaped H2s and H3s, FAQPage and Article schema, entity-rich prose. AI models pull from structured surfaces, not narrative paragraphs. | Long-form thought-leadership pieces with no structural extraction signal. AI cannot lift a citation cleanly from a wall of text. |
| Prompt-level targeting | Buyers ask AI tools different questions than they type into Google. LLM SEO starts from the prompt graph, not the keyword list. Mapping existing content against those prompts is the first piece of real work. | Keyword research deliverables only. If the agency cannot show you 30 to 50 specific prompts your buyers use in ChatGPT or Perplexity, they are doing keyword SEO. |
| Pipeline measurement | Traffic is a vanity metric for B2B SaaS. The agency should measure demo requests, free trial signups, and pipeline value attributed to organic, including AI-referral traffic. | Reports that lead with sessions and impressions. If the monthly review never connects work to revenue, the work is not aimed at revenue. |

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.
How long until LLM SEO actually works
The honest answer is different for different parts of the program. Three timeframes apply, and the agency that quotes a single number for all three is hiding which one matters for your category.
| Timeframe | What is possible | When it applies | Real example |
|---|---|---|---|
| Same-day to 1 week | First AI citation appears in ChatGPT, Perplexity, or Gemini | Page is Bing-indexed, FAQPage and Article schema are in place, direct-answer paragraph sits in the first 60 words, the target prompt has low competitive density | Internal LoudFace pattern: niche prompts where no incumbent owns the answer. |
| 2 to 8 weeks | Consistent citations across 2 to 3 AI platforms for the tracked prompt set | Net-new prompts where the prompt graph is still maturing, mid-density competition, structural retrofit work completed across the target pages | TradeMomentum: consistent citations across ChatGPT and Perplexity within roughly 4 weeks of the AEO restructure on their trading-bootcamp content. |
| 2 to 6 months | Primary recommendation status for category-defining prompts | Displacing an established incumbent, high competitive density, prompt graph is fragmented across many adjacent intents | Toku on the "stablecoin payroll" prompt: months of work to land 86% share of answer, in parallel with the prompt itself maturing as a category in AI training data. |
The compression points are structural. Pages cited in the first week share five things: Bing crawl already covering the URL, FAQPage and Article schema in place, a direct-answer paragraph in the first 60 words, an extractable comparison or list pattern AI surfaces as bullets, and a buyer-level title that matches the actual prompt language. Agencies that quote a fixed 90-day "ramp" without explaining which of these three timeframes they target are usually buying time, not shipping the structural work.
