More B2B buyers now start vendor research by asking ChatGPT, Perplexity, Gemini, Claude or Google AI Overviews for a shortlist. Answer engine optimization (AEO) and generative engine optimization (GEO) are the practices of earning accurate mentions and citations in those answers. This list is for B2B marketing and revenue leaders who want an outside team to do that work and want to know what good looks like.
The category is young. Many firms added "GEO" to an existing SEO page in the last two years, and there is no shared standard for measuring AI visibility, so claims are hard to verify from the outside. We describe only the capabilities each firm states on its own website, and the guidance below shows you how to test those claims.
Disclosure: this list is published by Lemniscate Growth, which is included.
Last checked: September 2026.
How we chose
- A working website with 2025 or 2026 activity, such as a current copyright year, dated resources or recent posts.
- A dedicated AEO, GEO or AI search service described on the firm's own site, naming engines such as ChatGPT, Perplexity, Gemini, Claude or Google AI Overviews.
- Clear evidence of B2B focus, such as B2B software, SaaS or technology named as a core audience.
- Specific methods stated in public: citation or share-of-answer measurement, entity and third-party source work, technical access for AI crawlers, and reporting.
- Headquarters taken from the firm's own contact or about page, or marked as not stated.
No firm paid to be included. Inclusion is based on public information on each firm's own website. After entry 1, the order is not a ranking.

How to choose an AEO and GEO agency for B2B
1. Measurement across engines, not screenshots
AI answers vary by prompt wording, session, location and model version, so one screenshot proves very little. Ask how many prompts the agency tracks, how often it re-runs them, and across which engines. You want share of answer, citation rate and accuracy of description tracked over time against named competitors.
2. Buyer prompts, not keyword lists
B2B buyers ask long, specific questions, such as which compliance tools suit a mid-size fintech or how two vendors compare on integrations. A good prompt set comes from sales call notes, win and loss reviews and CRM data, then gets grouped by funnel stage.
3. Entity and third-party source work
Models tend to cite sources they can cross-check. For B2B that usually means review sites, comparison articles, analyst and partner directories, community threads and industry media. The agency should map which sources are cited for your category today, make your company description consistent everywhere, and have a realistic plan to earn presence on the sources that matter.
4. Technical access for AI crawlers
Check that robots.txt rules allow the AI crawlers you want, such as GPTBot, ClaudeBot and PerplexityBot, and that key content does not depend on client-side JavaScript to render. Schema, clean product and comparison pages, and clear pricing and integration pages all help systems describe you correctly.
5. Reporting that connects to pipeline
AI referrals often arrive with little or no referrer data. Ask how the agency will show influence: self-reported attribution fields on demo forms, branded search trends, sales call mentions and CRM opportunity data. Visibility without a pipeline story will not survive a budget review.
6. Fit with the rest of your go-to-market
GEO depends on PR, executive visibility, product marketing, review programs and partner marketing. An agency that works only on your website will hit a ceiling. Ask who owns the off-site work and how they coordinate with your team.
Questions to ask on the first call
- Which engines do you track, how many prompts per client, and how often do you re-run them?
- How do you build the prompt set, and can we add prompts from our own sales calls?
- Can you show an anonymized baseline report that includes competitor share of answer?
- Which third-party sources are cited most in our category today, and how would you earn presence there?
- What technical changes do you make for AI crawlers, and who implements them on our site?
- How will you report pipeline influence when AI referrals are hard to attribute?
- What do you do when a model describes our product or pricing inaccurately?
- Which parts of your plan are specific to GEO, and which are standard SEO and content?
- Who will actually do the work, and what B2B experience do they have?
Red flags
- Guaranteed placement or promises to make you the top recommendation in ChatGPT. No agency controls model outputs.
- Proof of results based on a handful of screenshots rather than repeated prompt sampling.
- A GEO page that reads like a renamed SEO page, with no mention of measurement, entities or third-party sources.
- Plans to mass-produce thin AI-written pages or seed fake reviews and community posts.
- A proprietary visibility score with no explanation of how it is calculated.
- Reporting that tracks mentions only and never connects to demos, opportunities or revenue.
- No clear answer on whether AI crawlers can reach and read your key pages today.
Next step: get a baseline first
Before you sign with any agency, get a baseline: which prompts matter to your buyers, which engines mention you, which sources they cite instead, and whether AI crawlers can read your key pages. That baseline makes every pitch easier to compare.
