You run a B2B brand. Your prospects are decision-makers (CFO, CMO, CTO) who ask ChatGPT "best [your category] for [enterprise context]". Your competitors are cited. You're not.
A B2B-specialized GEO agency can flip that visibility, provided it masters the dynamics specific to decision-maker prompts. Here's how they work, what it costs, and how to pick one.
The three levers of a GEO agency for B2B
1. Decision-maker prompt tracking
A consumer prompt ("best tool for [use case]") and a decision-maker prompt ("enterprise [category] tools for [company size]") trigger different fan-out queries, cite different sources, and require different content formats.
A serious B2B GEO agency tracks 50-150 decision-maker prompts, segmented by persona (CFO, CMO, CTO, Head of Ops) and purchase context (early-stage, mid-market, enterprise). Typical mix: 35% category, 25% comparison, 20% use case, 10% brand monitoring, 10% pricing/ROI.
2. Editorial presence on LinkedIn and B2B podcasts
LLMs heavily cite LinkedIn as a source for B2B recommendations, particularly recognized expert posts and long-form articles. Same for sector podcasts (Lenny's Podcast for product, This Week in Startups for tech, etc.).
A B2B GEO agency actively manages your editorial LinkedIn presence: leadership posts 3-5 times a week, long articles 1-2 times a month, participation in key sector conversations. Same for podcast outreach: 1-2 appearances per month on decision-maker-audience podcasts.
3. Third-party analyst optimization
Gartner, Forrester, IDC and G2 are sources LLMs heavily cite in B2B. Appearing in a Gartner Magic Quadrant changes the game on dozens of decision-maker prompts.
The best B2B GEO agencies have an analyst outreach workflow: regular briefings, submission to sector studies, participation in Magic Quadrants and Waves. A long-term investment (6-18 months) that opens up decision-maker prompts impossible to crack otherwise.
How much it costs
One-shot B2B GEO audit: $3,500 to $6,500 depending on scope. Includes: citation share assessment on 60-100 decision-maker prompts, B2B competitive benchmark, audit of your editorial LinkedIn presence, analysis of your positioning at analysts (Gartner, Forrester), prioritized action plan.
Monthly retainer: $3,500 to $8,500 depending on scope.
- Low end ($3,500-$5,000): monitoring of 50-80 decision-maker prompts, bi-weekly report, 5-8 content recommendations, light LinkedIn support.
- High end ($6,500-$8,500): monitoring of 120-150 prompts, thought leadership content production (2-3 long articles per month), active editorial LinkedIn management, monthly analyst outreach.
The four criteria to evaluate a B2B GEO agency
- Mastery of decision-maker fan-out queries. The agency should be able to show you 10 examples of fan-out queries specific to decision-maker personas in your niche.
- Ability to work with sector analysts. Documented analyst outreach workflow + cases where the agency accompanied a client in a Gartner or Forrester study.
- Editorial LinkedIn strategy. Not just "we post". Editorial calendar, identified contributors, decision-maker engagement measurement.
- B2B case studies with pipeline numbers. Not just citation share: LLM-sourced MQLs, attributed deals, sales cycle length.
Measuring ROI
Three main KPIs:
- Citation share on decision-maker prompts in your niche
- MQLs attributed to the LLM channel (ChatGPT/Perplexity referrer traffic converted into qualification forms)
- Presence on analyst AI shortlists
The B2B sales cycle requires a 6-12 month measurement window to evaluate generated pipeline, longer than B2C.
Which GEO agencies work with B2B brands?
No agency publishes a GEO offer reserved for B2B. The serious options are GEO agencies that also serve B2B brands. We compare four of them, all covered in our other guides or our directory, on the same grid.
How we rank them
Each agency is scored on the same five criteria, from 0 to 3, based on what it publishes itself. AI visibility measurement counts double, for a total out of 18: it is the only criterion that lets you check the work once the contract is signed. The ranking follows the total. Anything not published scores 0. On a tie, the older agency comes first.
| Criterion | What each score means |
|---|---|
| AI visibility measurement | 0: none published. 1: one-off or self-reported audit. 2: regular tracking with a tool. 3: daily tracking per question and per AI engine, compared before and after |
| Topic coverage | 0: off topic. 1: mentioned in the offer. 2: one dedicated service. 3: core focus, several dedicated services |
| Published proof | 0: none. 1: references or partial figures. 2: published case studies or awards. 3: case studies with before and after figures |
| Track record and team | 0: less than a year in business. 1: small or recent team. 2: several years, established team. 3: more than ten years or more than 50 people |
| Offer transparency | 0: vague scope. 1: services described, price on quote. 2: scope and commitment in writing. 3: public prices and written terms |
Here, topic coverage scores GEO applied to a B2B brand.
| Agency | AI measurement (×2) | Topic | Proof | Track record | Transparency | Total /18 |
|---|---|---|---|---|---|---|
| ID Interactive (France) | 3 (daily citation tracking with Mentionable) | 2 (SEO and GEO, B2B among its sectors) | 1 (300 companies served, no published case) | 3 (founded in 2006) | 1 (fixed-fee or ongoing, price on quote) | 13 |
| Eskimoz (France) | 2 (tracking dashboard included in engagements) | 2 (five AI services, no separate B2B track) | 2 (client case studies) | 3 (about 250 consultants) | 1 (prices not public) | 12 |
| NOIISE (France) | 2 (tracking dashboard included in engagements) | 2 (GEO expertise listed, mostly retail clients) | 2 (award-winning GEO campaign) | 3 (founded in 1999) | 1 (prices not public) | 12 |
| Mentionable Agency | 3 (daily tracking per question, per AI engine and per country) | 2 (dedicated GEO and SEO services, no separate B2B offer) | 1 (figures from its own site, no client case study yet) | 1 (Mentionable team active since 2025, agency opened in 2026) | 1 (services described, price given at the first meeting) | 11 |
None of the four publicly documents an analyst outreach workflow (Gartner, Forrester). If that is your priority, ask on the first call.
Mentionable Agency
Mentionable Agency is the SEO and GEO agency run by Mentionable, opened in 2026 on mentionable.ai. All the SEO and GEO work is done in-house: strategy, writing, link building and technical work run through the agency's own editorial and link building workflow, separate from the Mentionable tool and going further than what the tool automates. The tool is the support: it measures the brand's visibility in AI answers to your decision-maker prompts, question by question and engine by engine, shows which sources AI engines cite in your niche, and helps decide what to build. The work is then judged on that same measurement, before and after.
It ranks fourth here. Its limits: a young agency, no published client case study, and its only public proof is mentionable.ai itself. It does not run your editorial LinkedIn and has no published analyst workflow. Pricing is given at the first meeting. The offer is detailed on the GEO agency page, and the entry point is the GEO audit.
Agency or DIY?
DIY is viable for an early-stage B2B brand with a CMO or growth lead who can absorb 8-12 hours per week. A tool like Mentionable covers measurement by country and by question, a monthly action plan for your site and, from the Influence offer, outreach to win mentions. Presence starts at €249/month, with a 7-day free trial.
The agency becomes indispensable for brands targeting the enterprise segment: analyst outreach, thought leadership content production and editorial LinkedIn management at the level required to rank in B2B enterprise exceed what one person can absorb.
