Criterion	onlinewachsen.de	Engine Native	getSichtbar	Sichtlabs
Company focus	Broad digital agency with a documented path from GEO measurement to implementation. [53][54] The statements come from public vendor communication. They document the described scope but do not prove an independent performance advantage over other agencies.	Specialist GEO agency focused on AI answer systems. [58] The positioning comes from the agency itself and does not establish a quality ranking.	SEO and AI Search with software plus implementation. [56] The website also includes classic SEO and web services. A GEO engagement should therefore be assessed by its actual scope.	GEO specialist for B2B and complex markets in the DACH region. [57] The positioning comes from the agency itself and is not an independent quality assessment.
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.
