How to Choose Your B2B SEO and AEO Agency in Germany

Written by Sandra Rieck | Aug 19. 2026

A good B2B SEO and AEO agency is characterized by proven B2B experience, reliable SEO performance, and a proven methodology for achieving visibility in AI search systems such as ChatGPT, Perplexity, and Google AI Overviews.

If you systematically ask about these points during the initial consultation, you’ll quickly identify the right agency. This guide shows you what matters most.

What sets a B2B SEO and AEO agency apart from traditional SEO?

Traditional SEO boosts your pages’ rankings in organic search results. AEO—Answer Engine Optimization—also ensures that AI systems cite your content as an answer, often without requiring a click through to the website.

For B2B companies with long purchasing processes, both are important: search engines continue to drive traffic, while AI answers are increasingly shaping the initial selection process in the buying center. A B2B SEO and AEO agency therefore covers technical SEO, content architecture, and AI visibility all in one.

We've summarized the basics of AEO, content structures, and measurement in our guide AI Discoverability for B2B 2026

How can you tell if an agency has B2B experience?

B2B experience is demonstrated by the ability to translate complex offerings into content for multiple decision-makers. Check these points:

  • References from B2B industries: Case studies from manufacturing, IT, or services that require explanation show whether the agency understands your business model.

  • Understanding of lengthy buying processes: Content that specifically addresses the research, comparison, and decision-making phases.

  • Knowledge of the buying center: Engaging CEOs, CMOs, Heads of Sales, and RevOps managers with content tailored to each role.

  • Dedicated points of contact: a team with consistent points of contact that supports your business model over several months.

What criteria indicate genuine SEO performance?

Performance can be measured, not just claimed. Look for:

  • Technical foundation: Load time, crawlability, structured data, and clean markup as the foundation upon which AEO is also built.

  • Content architecture: Topic clusters instead of individual articles, with clear internal linking.

  • Transparent reporting: Rankings , organic traffic, and leads in a dashboard you can easily understand.

  • Subject-Matter Expertise: Content teams with a genuine understanding of your products and target audiences.

How do you assess an agency’s AEO expertise?

An agency with genuine AEO expertise will show you live citations, cite specific search queries instead of broad statistics, and deliver both technical implementation and copywriting from a single source. Four checkpoints can help:

  • Live proof instead of screenshots: The agency shows you a current query in ChatGPT, Perplexity, or Google AI Overviews that cites an existing client as the source.

  • Specific search queries instead of overall metrics: Anyone measuring your visibility should specify the exact prompts and platforms used.

  • Technical depth: Structured data and schema markup as an integral part of the proposal.

  • Realistic timelines: A good agency will only make reliable statements about the timeline after analyzing your current visibility—not during the initial meeting. I’d be skeptical of anyone who promises blanket weekly estimates without reference to your starting point.

Test it yourself first: The free HubSpot AI Search Grader shows how visible your brand currently is in AI search systems. This gives you a baseline for your discussions with any agency.

What warning signs indicate a weak B2B SEO and AEO agency?

Three warning signs are common:

  • Ranking metrics without any AI context: The agency only shows traditional rankings and dodges questions about AI citations.

  • Immediate long-term contracts: An offer for twelve months before any initial results have been demonstrated shifts the risk onto you.

  • Your website as the only lever: Trust signals on third-party sites, mentions, and reviews go unmentioned, even though they contribute significantly to AI visibility.

What questions should you ask during your initial meeting with the agency?

These questions distinguish a specialized B2B SEO and AEO agency from a generalist agency:

  • Which B2B clients are you currently serving, and in which industries?

  • Can you demonstrate in real time how a client is currently being cited in ChatGPT or Perplexity?

  • What does your reporting look like after three, six, and twelve months, and which search queries do you track?

  • Who writes the content, and how does the team adapt to our topic?

  • How do SEO, AEO, and our CRM fit together in your approach?
