If you’re evaluating agencies for generative engine optimization (GEO), this shortlist gives you ten providers that publicly describe GEO, answer engine optimization (AEO), or AI-search services. It is an options list, not a ranking or a guarantee of results: compare each agency’s engine coverage, work, measurement plan, and evidence against your needs.
What GEO agencies do—and why their scope matters
Generative engine optimization, answer engine optimization, and AI-search optimization are overlapping labels for work intended to improve how a brand or its material appears in generative answers. The terms do not, by themselves, tell you which platforms, tasks, or outcomes an engagement covers. Ask each provider to define those details.

AI-search systems do not all draw on the same sources or behave identically. A 2025 research paper reports differences in source mix, domain diversity, freshness, cross-language stability, and sensitivity to phrasing. That makes engine-specific scope and repeatable measurement more useful than a broad promise of “AI visibility.” See the 2025 study.

The agencies below are presented alphabetically as options to investigate, not ranked by performance. Their service pages show that they market relevant services; they do not establish what results a new client will receive.

Rank #2
Intero Digital
Intero Digital describes GEO services and publishes client examples involving AI visibility, Google AI Overview appearances, and engagement from AI referrals. Treat any figures as claims reported by Intero Digital, rather than as independently verified comparisons. Visit Intero Digital’s GEO page.
iPullRank
iPullRank describes GEO programs covering strategy, content, technical optimization, and measurement. The agency also says that achieving results in AI search remains a work in progress. Its larger revenue figures are not presented as GEO-only results, so they should not be used to infer the impact of GEO work. Visit iPullRank.
Jumpstart GEO
Jumpstart GEO publishes details about engine coverage, tracked terms, reporting, and service components. Its page lists plans at $200, $500, and $1,000 per month, plus a one-time initiation fee; the prices are per location or firm and are specific to Jumpstart GEO’s own offering. Confirm current fees, scope, and terms directly with the provider. Review Jumpstart GEO’s plans.
POLARIS
POLARIS describes work involving entities and knowledge graphs alongside third-party and earned-media citations. Ask how those activities connect to the engines and outcomes in your scope. Visit POLARIS’s GEO page.
SEO Yodha
SEO Yodha markets GEO for ChatGPT, Perplexity, and Google AI, and publishes visibility and campaign figures. Those figures are agency claims; ask for the measurement window, data source, and denominator before using them to compare providers. Visit SEO Yodha.
Siege Media
Siege Media markets GEO and publishes client examples involving content, technical structure, and AI citations. Its site identifies a GEO book by founder Ross Hudgens as a Wiley book. Any performance examples on the agency’s site should be read as Siege Media’s own reporting. Visit Siege Media.
Zeo
Zeo has a GEO and AI-search optimization service page. The available page description refers to strategy and AI-search audits, but does not provide enough detail here to characterize its methods, client results, or current plan scope. Ask for a current proposal that spells those out. Visit Zeo’s service page.

What languages, countries, and locations are covered?
- Work delivered: Does the engagement include technical SEO, content creation or revision, digital PR and earned media, structured data, entity work, or only reporting and recommendations?
- Measurement: Which buyer prompts or queries will be tracked? How will the baseline be set, how often will results be measured, and will referrals or business outcomes be separated from visibility counts?
- Evidence: For each case study, what was the measurement window, denominator, and data source? Was the work for a client or the agency’s own marketing? The examples cited above are agency-published claims, not a common independent benchmark.
- Fit and execution: Can the provider demonstrate relevant experience for your industry, geography, and regulatory environment? Do you have the internal content and engineering capacity the proposed work needs?
- Commercial terms: Get the scope, fees, contract term, deliverables, and ownership terms in writing. Public prices are not available in comparable form for all ten providers; Jumpstart GEO’s listed figures describe that provider’s own plans and can change.
A practical interview question is: “Which engines and buyer prompts will you measure, what is the starting baseline, and what evidence will show that the work changed?”
How to interpret agency results and pricing
A case study can help you understand what an agency says it did and measured, but it is not an apples-to-apples test of providers. Before relying on a reported lift, look for the time period, starting point, data source, and definition of the outcome. A rise in AI mentions or referrals does not automatically establish an increase in qualified leads or revenue.
Likewise, the Jumpstart GEO prices are not a market average: they are the prices its page lists for its own plans, priced per location or firm, plus a one-time initiation fee. The reviewed pages do not provide a comparable pricing survey for the other agencies. Verify any current proposal and what it includes before comparing cost.
Choosing the right fit
Start with your actual need: a defined set of target markets and engines, the work your team cannot do in-house, and an outcome you can measure. Then ask two or three relevant providers to propose the same scope and reporting method. A specialist’s platform coverage, technical and editorial capabilities, industry fit, and proof standards matter more than a headline claim or an unqualified ranking.
