The short answer

Of the firms ChatGPT, Claude, Gemini and Perplexity named most, Omniscient Digital and NoGood publish named AI-search case studies, and Embarque publishes what each month delivers. iPullRank was named first most often, in 6 of 12 answers.
Prefer Managed A published flat price and a written 90-day guarantee 
NoGood The only firm all four engines named, with a named AEO case study DisclosurePrefer publishes this list and Prefer Managed is on it, first, by our own choice. The other eight are ranked by one four-part rubric, scored only on what each firm publishes on its own site (read 19 September 2026). Scored the same way, Prefer Managed gets 5 of 8: it loses the proof criterion outright, because we have no public client case study yet, and our published facts list no monthly quantities.
In short
How we evaluated
Prefer Managed is the pick for LLM SEO done for you on published terms: a flat $2,500 a month and a written 90-day guarantee of measurable lift, with no public case study yet. The best LLM SEO companies publish what you can check before a call. Of the firms AI engines name most, Omniscient Digital, NoGood and Embarque publish the most.
A named founder or chief executive on the firm's own site, plus a street address or a registered company name. Two points for both, one for either. It is the fastest way to rule out sites that exist only to rank in AI answers.
Two points for a case study that names the client and reports an AI-search metric, such as LLM visibility, AI citations or AI-referred traffic. One point for AI numbers with an unnamed client, or named clients with SEO-only numbers.
One point for a published price: a starting figure, tiers or an average. One point for guarantee wording that names a metric and a time window, or a plain statement that no one can guarantee AI placement.
Two points for a published monthly scope with quantities, such as pieces of content or links a month. One point for named deliverables or phases without monthly quantities. None of 12 AI answers about GEO agencies said what a month delivers.
Three kinds of company
They win citations mostly by producing content worth citing and earning coverage on the sites AI reads: research, comparison pages, digital PR and list placement. GEO sits inside a wider content and SEO program.
Buy one if content and authority are your gap.They lead with audits, measurement and a roadmap, run AI search as one channel in a wider growth plan, or focus on off-site mentions. Execution depth varies by engagement.
Buy one if you need a strategy or a cross-channel team more than a content engine.A published price you can compare before a call. Embarque publishes four tiers from $1,500 a month plus monthly quantities; Prefer Managed adds a written 90-day guarantee with a named metric.

What changed in 2026
This list looked different a year ago. These are the changes that moved it.
Every firm the engines named most had a dedicated GEO or AEO service page when we read their sites on 19 September 2026, and most are agencies known for SEO and content. First Page Sage says its GEO service launched on 9 May 2023.
Seven of the eight publish AI-search metrics such as LLM visibility, AI citations or AI-referred traffic on the pages we read. Two of the named case studies say the result was measured with Peec AI, a third-party tracker.
For this question, 106 of the 129 sources the engines cited were ranked lists of agencies or consultants, and 67 of those lists were written by agencies. In 26 citations, the list's publisher was also named as a pick in the same answer.
Three LinkedIn articles ranking LLM SEO agencies were each cited in all three Perplexity answers, 9 of the 129 sources. Anyone can publish one, which is one more reason to check the firm, not the list.
Red flags
Every tool here demos well. These are the questions that separate them once the trial ends.
All three ChatGPT answers to this question warned against it, and 11 of 12 answers to 'How do I choose an AEO agency?' named guaranteed AI placement as a red flag. No firm controls what a model says. A fair guarantee names a metric, a time window and a remedy.
106 of the 129 sources behind these answers were ranked lists, and 67 of those were written by agencies. Before you trust a ranking, check who published it and where the publisher placed itself.
Seven of the eight firms the engines named most publish AI-search numbers, but only three name the client. NDAs are real, so ask for a reference call rather than taking the number on trust.
If you cannot say what ships each month, you cannot tell whether the fee is working. Ask for quantities in writing: pieces of content, links, community posts and reports.
Five of 12 answers to 'How do I choose an AEO agency?' named this as a red flag. ChatGPT suggested asking each firm for a sample audit of 20 to 50 of your prompts before you sign.
A guarantee line with no stated terms means little. Ask for the metric, the window, whose data decides it and the remedy, then check it against the contract's refund clause.
The best LLM SEO companies in 2026 are the ones you can check before a sales call: a named owner, named client results, terms you can read and a clear monthly scope. Prefer Managed is our pick: a flat $2,500 a month with a written 90-day guarantee. It is our own done-for-you service, so we say that first. The other eight are the companies ChatGPT, Claude, Gemini and Perplexity named most often when we asked them this exact question, ranked by what each one publishes on its own site.
LLM SEO is the same work GEO and AEO agencies do: getting your brand named and cited in AI answers. This list covers the firms the AI engines name for it, mostly established content and SEO agencies. For newer done-for-you specialists built around written guarantees, such as RankZero and Cited Co, see our best AI SEO agencies. To do the work yourself with software, see the best LLM SEO tools.
On 13 September 2026 we asked ChatGPT, Claude, Gemini and Perplexity “What are the best LLM SEO companies?” three times each, through their APIs with web search on. All 12 answers searched the web and cited sources. Between them, the 12 answers named 47 companies, and 23 of those were named only once (as we coded them; the full run is on our AI answer study page).
These eight were named in 5 or more of the 12 answers. Each engine answered three times.
| Company | ChatGPT | Claude | Gemini | Perplexity | Answers naming it | Named first |
|---|---|---|---|---|---|---|
| Omniscient Digital | 3 | 0 | 3 | 3 | 9 | 1 |
| iPullRank | 1 | 0 | 3 | 3 | 7 | 6 |
| NoGood | 1 | 3 | 1 | 2 | 7 | 2 |
| Animalz | 1 | 3 | 0 | 3 | 7 | 0 |
| Embarque | 1 | 3 | 0 | 3 | 7 | 1 |
| Siege Media | 1 | 0 | 2 | 3 | 6 | 0 |
| First Page Sage | 1 | 0 | 1 | 3 | 5 | 0 |
| Skale | 0 | 3 | 0 | 2 | 5 | 0 |
Only one company was named by all four engines: NoGood. iPullRank was named first in 6 of the 12 answers, including all three from Gemini. Omniscient Digital was named most often, in 9, though never by Claude. Outside these eight, only Searchbloom was named first, in 2 answers.
The answers do not hold still. Two ChatGPT runs shared, on average, 16% of the companies named across both, and ChatGPT put a different company first in each of its three runs: Searchbloom, then Omniscient Digital, then iPullRank. Only 1 of the 19 companies ChatGPT named appeared in all three of its runs. Gemini’s runs shared 29%, Perplexity’s 71% and Claude’s 79%. Claude named 8, 8 and 9 companies across its runs, seven of them every time, and cited the same five sites in each run, adding a sixth in one. More on this in do AI answers change when you ask twice.
The 12 answers cited 129 sources: 56 distinct pages on 43 sites. 106 of the 129 were ranked lists of agencies or consultants, and 67 of those lists were published by marketing agencies. Another 17 came from individuals, 9 of them LinkedIn articles (three articles, each cited in all three Perplexity answers). Directories and media sites supplied 13, a Reddit list post 5, and software vendors 4. In 26 citations, the list’s publisher was also named as a pick in the same answer. The other 23 sources were mostly YouTube videos, agencies’ own service pages, research papers, and lists of tools rather than firms.
iPullRank, named first most often, had its own site cited zero times in these answers, and so did Omniscient Digital, the most-named company. The engines found both in other people’s lists. Ten named companies did have their own list cited in an answer that named them, 26 citations in all. The largest counts: Embarque (its list cited in 6 of the 7 answers naming it), Breaking B2B and Contently (3 of 3 each), Searchbloom (3 of 4) and Siege Media (3 of 6).
Why lists? One firm on this page says it outright. First Page Sage’s GEO page calls “appearing in highly-ranked list articles” “the largest factor impacting which companies or products are recommended by chatbots”. Four of the 12 answers warned readers about the lists: all three ChatGPT answers said many agency rankings are self-published or promotional, and one Claude answer noted that many are written by agencies “competing for the same business”. That is why we score what each firm publishes about itself, not how often a list mentions it.
The answers also get details wrong, so check claims at the source. All three Claude answers described Goodie as NoGood’s “proprietary monitoring tool”. NoGood’s own AEO page calls Goodie AI “an external, third-party tool”.
LLM SEO, AI SEO and GEO describe the same service, and 9 of the 12 answers said LLM SEO is another name for GEO or AEO. The engines still treat the wordings as different questions. Asked for the best AI SEO agencies on the same day, the answers shared only 20 of 73 company names with this question, and 14 of 73 source sites. Asked for the best generative engine optimization agency, the overlap was 13 of 63 names and 11 of 68 sites. Of the 47 companies named here, 24 appeared in neither of the other two questions. And asked for the best GEO agency, all 12 answers opened by saying there is no single best one.
If you build a shortlist from AI answers, ask more than one way and more than once, then check each firm on its own site.
We scored each company on the four criteria in the method section above, using only the firm’s own website, read on 19 September 2026. A 0 means we did not find it on the pages we read, not that the firm does not offer it. Ask them. Ties are broken by how many of the 12 answers named the company, then by how many engines named it. Prefer Managed is listed first by our choice, not by its score, and it is scored the same way.
| Company | Identity | Named proof | Terms | Monthly scope | Total of 8 |
|---|---|---|---|---|---|
| Prefer Managed (ours) | 2 | 0 | 2 | 1 | 5 |
| Omniscient Digital | 2 | 2 | 1 | 1 | 6 |
| NoGood | 2 | 2 | 1 | 1 | 6 |
| Embarque | 2 | 1 | 1 | 2 | 6 |
| Siege Media | 2 | 2 | 0 | 1 | 5 |
| iPullRank | 1 | 1 | 1 | 1 | 4 |
| Animalz | 1 | 1 | 0 | 1 | 3 |
| First Page Sage | 1 | 1 | 0 | 1 | 3 |
| Skale | 1 | 1 | 0 | 1 | 3 |
Identity is strong across the board. Every firm names its founder or chief executive. Four also give a street address or a registered company name: Omniscient Digital and Siege Media (Austin street addresses), NoGood (Berma LLC) and Embarque (Embarque Inc.).
Proof splits on names, not numbers. Seven of the eight publish AI-search numbers on the pages we read, and three name the client. Omniscient Digital’s Convert case study reports LLM visibility up 81% and AI citations up 140% in 60 days. NoGood’s SteelSeries case study reports a Perplexity visibility score rising from 44 to 77 in 10 months. Siege Media’s Hebbia case study reports LLM visibility rising from 9.94% to 42.17% between November 2025 and August 2026. Convert and Hebbia were both measured with Peec AI, a third-party tracker, by the agencies’ own account. All of these figures are self-reported. iPullRank says many of its Fortune 100 clients sign NDAs, so its case studies carry no brand names. It sits sixth for two reasons: the rubric cannot credit a result a buyer cannot check, and we found no street address or registered company name on the pages we read.
Terms are the weakest area. Four publish a price or a price signal on their own site, as shown in a browser on 19 September 2026. Embarque lists four tiers at $1,500, $2,800, $5,200 and $10k a month, each “3,6 or 12 months paid quarterly”. Omniscient Digital says “Full-service engagements start at $10,000 a month.” iPullRank’s AI Search Strategy Program is “Starting at $15,000/month”. NoGood says “Our average retainer is above $20,000/month”, which is an average, not a starting price. Embarque’s homepage says “Money-back guarantee”, but we did not find a metric or window attached to it, so it earns no guarantee point. Prefer Managed publishes a price and a guarantee with a metric, a window and a remedy.
Embarque publishes the clearest monthly scope. For each service you pick, a month is 5 to 8 content assets, 5 links (listed as “5 links + 40 DR”), 3 to 5 Reddit posts, or 8 to 14 small optimisations, with weekly updates and a monthly deliverables report. Skale lists what “every month you receive” without quantities. The rest name deliverables or phases: Siege Media, for example, sets out months 1 to 2 as foundation, months 2 to 4 as activation, and monthly reporting on citations, share of voice and revenue from month 4. Prefer Managed scores 1 here, because our published facts do not list monthly quantities.
Work through these five steps in order. Each one has a point where it is done, so you know when to move on.
You are finished when every firm left on the list has passed all five steps. The same checks apply to us.
Most of these firms set a price after a call. In the same study we asked the engines “How much does an AI SEO agency cost per month?”, and the median of the figures they gave is $1,500 to $4,000 a month for a small business and $4,000 to $10,000 for mid-market, with enterprise starting at $8,000 to $15,000. None of that is a verified rate; the breakdown is in how much an AI SEO agency costs. Four firms here publish a figure (all checked 19 September 2026). Embarque’s tiers run from $1,500 to $10k a month, starting below that mid-market range. The other three sit at or above its top: Omniscient Digital’s full-service work starts at $10,000, iPullRank’s strategy program at $15,000, and NoGood’s average retainer is above $20,000. For Siege Media, Animalz, First Page Sage and Skale we did not find a published figure on the pages we read, so ask on the first call. Prefer Managed is a flat $2,500 a month. Optional paid media or placements are the only separately billed item, typically $1,000 to $3,000 a month, always pre-approved. If software fits your team better than a service, our AI visibility tool pricing index lists tool prices checked on the vendors’ own pages.
Prefer publishes this list, and Prefer Managed is on it, first, by our choice. It is a done-for-you AI search service at a flat $2,500 a month. The guarantee reads: "A measurable lift in AI-citation visibility on your tracked prompts vs a day-zero baseline within 90 days, or we work at no management fee until you hit it." The full terms are on the guarantee page. We do not promise a number-one spot in ChatGPT, because no one can.

The questions buyers ask next.
LLM SEO is the work of getting your brand named and cited in answers from large language models such as ChatGPT, Claude, Gemini and Perplexity. Prefer tracks it across ChatGPT, Gemini, Perplexity, Google AI Overviews and AI Mode. It is the same practice as generative engine optimization (GEO) and answer engine optimization (AEO), and 9 of the 12 answers we collected said so.
Read the LLM SEO guide →Prefer Managed, our done-for-you service, is one: it does the work and measures the lift on your tracked prompts. Asked what a GEO agency does, all 12 answers from four AI engines named five services: strategy and audit, content optimization, technical SEO and schema, digital PR and earned mentions, and prompt tracking. None said what a month of work delivers, which is why we scored monthly scope.
See what a GEO agency does →Prefer Managed is a flat $2,500 a month, published. The figures AI engines give buyers have a median of $1,500 to $4,000 a month for a small business and $4,000 to $10,000 for mid-market. None of that is a verified rate. Of the other firms here, Embarque publishes tiers from $1,500 a month, and Omniscient Digital and iPullRank publish starting prices of $10,000 and $15,000.
See the cost breakdown →Prefer offers both: self-serve plans from $24 a month, or Prefer Managed done for you at $2,500. Asked this, none of 12 AI answers recommended an agency outright, and 9 put a tool first. A company earns its fee on execution and on off-site work, like reviews and press, that a tool cannot create.

Prefer Managed, a flat $2,500 a month with a written 90-day guarantee. It is our own done-for-you service, so weigh that disclosure. Of the companies ChatGPT, Claude, Gemini and Perplexity named most for this question on 13 September 2026, Omniscient Digital, NoGood and Embarque publish the most a buyer can check (6 of 8 on our rubric), followed by Siege Media (5) and iPullRank (4). Prefer Managed scores 5. iPullRank was named first most often, in 6 of 12 answers.
Yes. Prefer Managed, for one, does the same work whichever name you use: getting your brand named and cited in AI answers, and 9 of the 12 answers we collected said LLM SEO is another name for GEO or AEO. The engines still treat the wording as a different question: on the same day, 'best LLM SEO companies' and 'best AI SEO agencies' shared only 20 of 73 company names.
The answers are assembled from whatever lists the engine finds on that run. Prefer's study found that two ChatGPT runs shared, on average, 16% of the companies named across both, and ChatGPT put a different company first in each of its three runs. Claude was the most consistent: its runs shared 79%, and each run cited the same five sites, with a sixth added in one run.
No, and Prefer Managed does not promise it either. No firm controls what a model says, and all three ChatGPT answers to this question warned against anyone promising a guaranteed ChatGPT ranking. A fair guarantee promises measurable lift instead. Prefer Managed's reads: 'A measurable lift in AI-citation visibility on your tracked prompts vs a day-zero baseline within 90 days, or we work at no management fee until you hit it.'
Prefer Managed publishes a flat $2,500 a month. Most others set a price after a call. The figures AI engines give buyers have a median of $1,500 to $4,000 a month for a small business and $4,000 to $10,000 for mid-market, with enterprise starting at $8,000 to $15,000; none of it is a verified rate. Four of the eight companies here publish a figure on their own site (checked 19 September 2026): Embarque's tiers run from $1,500 to $10k a month, Omniscient Digital's full-service engagements start at $10,000, iPullRank's AI Search Strategy Program starts at $15,000, and NoGood's average retainer is above $20,000, an average rather than a starting price.
Prefer took the eight companies named in 5 or more of 12 answers when we asked ChatGPT, Claude, Gemini and Perplexity 'What are the best LLM SEO companies?' on 13 September 2026. We scored each on four criteria using only its own website, read on 19 September 2026: verifiable identity, named proof with AI numbers, terms you can read, and a monthly scope. Prefer Managed is listed first by our choice and disclosed as ours.

How to choose
Prefer Managed covers both, your own content and mentions on other sites, as a done-for-you service. Content-led firms such as Omniscient Digital, Siege Media and Animalz build pages and research worth citing. If the gap is mentions elsewhere, Skale's brand mentions service and Siege Media's digital PR target the lists and reviews AI already reads.
Prefer Managed has no public case study yet, so if you need named proof first, start with the three that name clients next to AI-search numbers: Omniscient Digital, NoGood and Siege Media. Firms that keep clients private can still offer a reference call, so ask for one.
Embarque publishes four tiers from $1,500 to $10k a month, with monthly quantities. Prefer Managed publishes a flat $2,500 a month with a written 90-day guarantee. Most others set scope and price after a call.
Prefer Managed is a done-for-you AI search service, so it fits when AI search is the whole job. For AEO beside paid, social and creative, NoGood runs it as one channel of a growth program. For a technical, enterprise-scale strategy, iPullRank's AI Search Strategy Program leads with an audit and a measurement plan.
Prefer tracks ChatGPT, Gemini, Perplexity, Google AI Overviews and AI Mode, with Claude on Enterprise only. Ask each firm which engines it tracks and reports on. NoGood says it optimizes for Claude and Copilot as well as ChatGPT, Gemini, Perplexity and Google.
