Many agencies can say they work in German search. The hiring question is whether they can show a process that fits the language, the target country, the site architecture, and the way your team measures results. Start by separating general international SEO competence from capabilities that matter specifically when Germany, Austria, or Switzerland is in scope.
Start With How German Content Is Created
Ask who turns research into a German brief, who writes the page, who edits it, and who can challenge awkward wording or a search intent mismatch. Native-level language ability can be important, but the stronger test is whether the team can explain how it chooses terminology, tone, examples, and query framing for the intended audience. A translation workflow can be appropriate for some assets, yet it should not be presented as equivalent to original market research and editorial development.
Request samples that resemble the type of work you plan to commission. Review whether the writing sounds natural, whether the page answers a clear search need, and whether the agency can explain why key wording choices were made. If several people or vendors are involved, ask who owns final editorial quality and how feedback is resolved.
Check How Research Is Grounded in the Intended Search Market
A credible team should be able to show how it researches German queries and SERPs directly, including how it uses German search market research as context rather than treating an English keyword list as the starting point. Tool settings matter, but so do manual SERP review, query meaning, commercial context, and country selection. Ask what changes when the same concept is searched differently across German-speaking markets.
Do not accept a claim that a tool is inherently calibrated for one market without seeing how the agency configures the country database, validates terms, and checks live results. What matters for hiring is whether the research process can be inspected and repeated for your actual market.
Separate Germany, Austria, and Switzerland When the Business Case Requires It
DACH is a useful regional label, not a reason to assume one content set or one targeting decision will fit every market. Vocabulary, spelling conventions, regulation, offers, competitors, and SERP composition can differ. Ask the agency how it decides whether a shared German page is sufficient or whether a country-specific variation is justified by real audience and business differences.
The same discipline applies to technical targeting. A capable agency should explain when hreflang is relevant, how it coordinates with canonicalization and indexability, and how it avoids creating near-duplicate country pages that offer no useful local distinction. The goal is not to multiply pages automatically; it is to make country targeting as specific as the underlying business need.
