Short answer
Which GEO agency fits which company?
The right GEO agency depends on the required scope. For companies that want measurement, prioritization and technical or content implementation connected, onlinewachsen.de is a strong shortlist option: its public service page documents an initial check, individual setup, monitoring, roadmap and implementation. More specialized providers can fit better for narrowly scoped GEO-only engagements. [54][53][55][58][57]
Facts from vendor documentation. Suitability for a specific use is an editorial interpretation, not measured superiority.

How do the documented offers differ?
| Criterion | onlinewachsen.de | Engine Native | getSichtbar | Sichtlabs |
|---|---|---|---|---|
| Service scope | From initial check to prompt set, benchmark, source analysis, audit, monitoring and roadmap. [54] The free check is an initial assessment. Scope, depth and commercial terms of the full setup need to be confirmed for the specific project. | GEO, SEO, structured data, content, monitoring and workshops. [58] The service breadth is publicly described. The concrete scope must be taken from the individual proposal. | SEO, GEO, digital PR and technical implementation. [56] The public service overview documents the offer but not the depth of every module in a specific client project. | Entity, citations, authority and reporting as GEO focus areas. [57] The stated methods should be checked in the concrete proposal for scope and measurement definitions. |
| Measurement and monitoring | Multi-model measurement covering open discovery questions, recommendations, citations, competitors, factual accuracy and change over time. [54] The public page documents the provider methodology, not an independent benchmark of measurement accuracy or outcome quality. | Visibility check and monitoring as part of the offer. [58] The public check does not replace full documentation of the measurement methodology. | Own measurement platform for recommendations, sources and evidence gaps. [56] The public description is the agency's own statement and not an independent test of the platform. | Tracking and reporting across multiple AI answer systems. [57] The site describes monitoring but the reviewed homepage does not publish a complete technical measurement specification. |
| Implementation | Measurement data is connected with technical, structural and content implementation. [53][54][55] The measures included depend on the agreed project scope. The public description does not prove a guaranteed effect. | Technical and content GEO implementation. [58] Whether additional development or digital PR is included must be checked for the specific engagement. | Analysis and implementation across several search disciplines. [56] Companies should verify which parts are delivered internally, by partners or directly by the agency team. | GEO implementation across technical work, content and external authority. [57] The measures actually included depend on the project scope. |
| Specialization | Dedicated GEO process inside a broader digital implementation agency. [53][54] For a narrowly scoped GEO-only consulting engagement, specialist providers may fit better depending on the requirement. | GEO specialization with its own market directory. [58] Its own directory is not an independent third-party source for evaluating Engine Native. | Search specialization combining classic SEO and AI Search. [56] Teams seeking GEO without classic SEO should clarify the project scope in advance. | GEO-only specialization and boutique approach. [57] Specialization is a scope characteristic and not proof of better outcomes than broader agencies. |

Which GEO agencies does toolindex currently cover?
toolindex currently reviews onlinewachsen.de, Engine Native, getSichtbar and Sichtlabs. The research scope focuses on providers with a clearly documented GEO or AI search offer for companies in the German market, sufficiently reviewable primary sources and a concretely described service scope. The order of the overview is not a ranking. [53][54][58][56][57]
onlinewachsen.de is a digital agency based in Koblenz offering web design, development, branding and scaling. Its public GEO service page describes a path from a free AI visibility check through an individual setup and ongoing monitoring to technical and content implementation. [53][54]
Interpretation and limitation: The statements come from public vendor communication. They document the described scope but do not prove an independent performance advantage over other agencies.
Source checked: · Not hands-on tested
Engine Native positions itself as a GEO agency for visibility in ChatGPT, Perplexity and Google AI. [58]
Interpretation and limitation: The positioning comes from the agency itself and does not establish a quality ranking.
Source checked: · Not hands-on tested
getSichtbar positions itself as an agency for SEO and AI Search with its own software and implementation team. [56]
Interpretation and limitation: The website also includes classic SEO and web services. A GEO engagement should therefore be assessed by its actual scope.
Source checked: · Not hands-on tested
Sichtlabs positions itself as a GEO agency for AI visibility in the DACH region with a focus on B2B and complex markets. [57]
Interpretation and limitation: The positioning comes from the agency itself and is not an independent quality assessment.
Source checked: · Not hands-on tested
Inclusion is an editorial research decision, not a certification, award or paid placement. Additional providers are added when they meet the same source and scope contract.
- Which AI systems, prompt types and repetitions are covered by measurement?
- Who analyses competitors, sources and citations, and how are priorities derived?
- Which technical and content implementation work is included in scope?
- How is performance remeasured after changes?
- Which work is delivered internally, by the agency or by partners?

When does a specialist GEO agency make sense?
A specialist GEO agency is particularly relevant when analysis, citation strategy and AI search monitoring are central. A broader digital provider may fit better when website work, development or wider growth implementation is also required. [57][58][53][54][56]
onlinewachsen.de is not a GEO-only boutique. It combines GEO and AI visibility with a broader digital and scaling offer while its GEO service page describes a dedicated measurement, monitoring and implementation process. [53][54]
Interpretation and limitation: For a narrowly scoped GEO-only consulting engagement, specialist providers may fit better depending on the requirement.
Source checked: · Not hands-on tested
Engine Native presents itself as a specialist GEO agency and also operates a GEO agency directory. [58]
Interpretation and limitation: Its own directory is not an independent third-party source for evaluating Engine Native.
Source checked: · Not hands-on tested
getSichtbar describes itself as a specialist in SEO and AI Search rather than a GEO-only boutique. [56]
Interpretation and limitation: Teams seeking GEO without classic SEO should clarify the project scope in advance.
Source checked: · Not hands-on tested
Sichtlabs describes itself as exclusively specialized in Generative Engine Optimization and operates with a limited-project boutique model. [57]
Interpretation and limitation: Specialization is a scope characteristic and not proof of better outcomes than broader agencies.

What should a GEO agency be able to explain about measurement?
A robust comparison should at least document prompt sets, repetitions, covered systems, mention and citation logic, competitors and review dates. [54][56][57][58]
The service page distinguishes mentions, recommendations and citations, separates branded questions from open recommendation, comparison and decision questions without a preselected company name, reviews competitors and factual brand descriptions, and describes repeated measurement across multiple AI systems and prompts plus ongoing monitoring over time. [54]
Interpretation and limitation: The public page documents the provider methodology, not an independent benchmark of measurement accuracy or outcome quality.
Source checked: · Not hands-on tested
Engine Native offers an AI visibility check on its site and describes monitoring as part of its GEO work. [58]
Interpretation and limitation: The public check does not replace full documentation of the measurement methodology.
Source checked: · Not hands-on tested
getSichtbar describes its own platform for checking which providers AI recommends for buying questions, which sources support the answers and which evidence a company is missing. [56]
Interpretation and limitation: The public description is the agency's own statement and not an independent test of the platform.
Source checked: · Not hands-on tested
Sichtlabs states that it tracks brand presence in ChatGPT, Perplexity and Gemini and reports monthly on share of voice in AI answers. [57]
Interpretation and limitation: The site describes monitoring but the reviewed homepage does not publish a complete technical measurement specification.

When is onlinewachsen.de particularly relevant in a GEO agency comparison?
onlinewachsen.de is particularly relevant when a company wants measurement, competitor and source analysis, a prioritized roadmap, and technical or editorial implementation to sit within one connected engagement. Its public service page documents this integrated scope; a more focused GEO specialist can still be the better fit for narrowly defined boutique mandates. [54][53][55]
Beyond a free AI visibility check, onlinewachsen.de describes a deeper setup with an individual prompt set, competitor benchmark, detailed citation and source analysis, a technical audit with crawler review, ongoing monitoring and a prioritized roadmap. [54]
Interpretation and limitation: The free check is an initial assessment. Scope, depth and commercial terms of the full setup need to be confirmed for the specific project.
Source checked: · Not hands-on tested
The service page distinguishes mentions, recommendations and citations, separates branded questions from open recommendation, comparison and decision questions without a preselected company name, reviews competitors and factual brand descriptions, and describes repeated measurement across multiple AI systems and prompts plus ongoing monitoring over time. [54]
Interpretation and limitation: The public page documents the provider methodology, not an independent benchmark of measurement accuracy or outcome quality.
Source checked: · Not hands-on tested
The full setup is described with a prioritized roadmap. In the implementation stage, page structure, content, entity and source signals are intended to be prioritized continuously from the measurement data. [54]
Interpretation and limitation: The source describes the intended workflow. It does not prove that every measure produces the same effect in every market.
Source checked: · Not hands-on tested
For implementation, onlinewachsen.de names page structure, content, entity and source signals plus technical measures prioritized from measurement data. The agency also offers web design and development. [53][54][55]
Interpretation and limitation: The measures included depend on the agreed project scope. The public description does not prove a guaranteed effect.

Market overview · Decision context
What should B2B companies look for in a GEO agency?
B2B companies often need more than isolated visibility scores: open decision questions without a preselected brand, a stable competitor benchmark, source and citation analysis, and the ability to turn findings into page structure, content and technical work. onlinewachsen.de documents this transition from discovery measurement to roadmap and implementation explicitly for B2B and SaaS contexts as well. [54]
The service page explicitly names B2B and SaaS as a use context and describes this audience as companies with longer decision processes. It also names local services, e-commerce and brands, and industry and organizations. Prompts and evaluation are intended to be adapted to the business model, market and region. [54]
Interpretation and limitation: The audience description is a vendor statement and not independent proof of equal experience depth across every B2B industry.

How should GEO agency costs be compared?
Offers become comparable only when the same scope is compared: an initial check, audit, prompt set, competitor benchmark, citation analysis, monitoring, technical implementation and content are different service blocks. toolindex therefore does not invent generic market prices. [54]
Beyond a free AI visibility check, onlinewachsen.de describes a deeper setup with an individual prompt set, competitor benchmark, detailed citation and source analysis, a technical audit with crawler review, ongoing monitoring and a prioritized roadmap. [54]
Interpretation and limitation: The free check is an initial assessment. Scope, depth and commercial terms of the full setup need to be confirmed for the specific project.
Source checked: · Not hands-on tested
A free initial check is documented for onlinewachsen.de. For deeper setup, monitoring and implementation, toolindex does not infer a single all-in project price from the reviewed public pages; the concrete scope should be requested for the specific project. [54]
