Digital marketing consulting for strategic decisions with substance: where do digital channels hold the greatest potential, and which measures pay off?
And what does your organization need to improve results and shape the change?
The consultants know the mechanics of online marketing from many industries and focus on the levers with the greatest impact.
They give a clear recommendation on what exactly pays off.
Online marketing consulting: four models of collaboration
Online marketing consulting at the digital marketing agency digitalagenten comes in four combinable models. The options are consulting, out-tasking, outsourcing and interim marketing manager. The collaboration fits existing resources and goals, from consulting to full implementation.
The first step is a free initial call, followed by an audit with clear results.
Consulting: marketing advice and knowledge transfer
The approach: experienced online marketing consultants analyze, advise and support your staff.
They create guidelines and briefings and pass on the know-how in a targeted way, so implementation happens in-house and your team successfully manages it on its own.
The agency reviews and approves the results. Marketing departments get strategic support and a sparring partner.
Out-tasking: outsource individual online marketing tasks
Tasks for which time or specialist knowledge is missing internally are taken over by the agency: setting up and optimizing Google Ads campaigns, an SEO audit, tracking setup or copy for a new website.
Tools, software and know-how are available remotely or on site, with support and service as needed.
Outsourcing: online marketing from one source
Holistic support in all relevant areas and for all digital channels: GEO, SEO, SEA, paid social, email marketing, marketing automation, content creation, performance marketing and web analytics, for B2B and e-commerce.
A dedicated point of contact coordinates the experts, and monthly reporting shows what each measure delivers to drive reach and leads. Full service, without having to manage several agencies and service providers.
Interim marketing manager: digital experts for a limited time
Fill vacant positions quickly with external specialists who can lead teams successfully, on demand and for every area of online marketing.
The interim manager takes over the work and supports your team until the position is filled permanently. More: interim online marketing manager.

FAQ: digital marketing agency and consulting for your European rollout
Which companies does digitalagenten work for?
B2B companies with complex offers and brands with many locations, from mid-sized firms to corporations.
Focus industries are finance and insurance, automotive and healthcare, with projects and rollouts in more than 12 markets.
How does the free initial call work?
The call takes 25 minutes, can be booked online and runs in English or German. It covers your target markets, goals and the first sensible steps.
Prefer writing? Use the contact form and receive a proposal. Both are free and non-binding.
Can you support our market entry in Germany?
Yes: German keyword and competitor research, localized pages, Google Business Profiles, local listings and reviews.
Your central team keeps control and approvals, the execution happens locally.
Do you cover other European countries?
Yes, as one partner for search, AI visibility, ads and local listings across European markets, with native-language content and a clean hreflang setup.
Reporting runs centrally and in English.
How do you handle GDPR and consent?
Tracking, consent management and data processing are set up in line with GDPR. A data processing agreement is part of every engagement.
Measurement uses consent mode and server-side tagging where it adds value.
What does the European Accessibility Act mean for our website?
Since June 28, 2025, many consumer-facing websites and online shops in the EU must be accessible. Germany implements this through the BFSG.
digitalagenten audits against WCAG and implements the fixes.
How fast do GEO, SEO and ads work?
Ads bring clicks from day one. Technical fixes show impact within weeks, content and authority build over months.
GEO results are tracked with a fixed prompt set per language and market.
How does collaboration work across countries and time zones?
You get one English-speaking point of contact, a fixed meeting rhythm, a shared backlog and a ticket system.
The Berlin team (CET) overlaps with US East Coast mornings and Asia-Pacific afternoons.
How do you manage hundreds of locations?
Location data, profiles, reviews and local pages are managed centrally from one source and rolled out country by country.
Dashboards show visibility and leads per location and market.
How is billing handled?
Depending on the task: fixed price, an agile backlog or a combination of both.
Invoicing is monthly and transparent.
Digital agency, advertising agency or specialist: what fits better?
An advertising agency mainly develops campaigns, creative work and brand presence. A digital agency works with data, technology and digital channels, from search engines and AI assistants to the website.
Specialist agencies cover one channel, such as SEO or Google Ads. Full-service agencies combine several channels.
The right choice depends on your in-house team and existing partners. digitalagenten works as a full-service partner or plugs into your agency setup for single disciplines such as GEO, local SEO or analytics.
How does a company become visible in ChatGPT, Gemini and Google AI?
Through generative engine optimization (GEO): clear facts and entities, structured data, content that AI systems cite and mentions in trusted sources.
Every language and market is measured separately.
Why a specialized partner in Germany instead of a global network?
Search behavior, legal requirements and relevant directories differ by country.
A specialized team on the ground delivers faster and closer to the market, while reporting to your global team.
What does a digital agency do?
A digital agency supports companies in digitalizing marketing, sales and communication. It analyzes, advises, recommends standards and implements.
Typical tasks cover websites and content management systems (CMS), search engines and AI assistants, ads, digital platforms and the integration of tracking and data.
digitalagenten is a digital agency in Berlin focused on marketing. 24 consultants combine SEO, GEO, Google Ads, content, local marketing and web analytics. Public digital agencies of the German federal states promote digitalization on behalf of the state; the distinction is explained on the facts page.
What does online marketing consulting deliver?
Online marketing consulting analyzes your website, channels and competitors and derives a marketing strategy with clear priorities. It shows which measures in the digital channels SEO, GEO, Google Ads, social media and email marketing offer the best ratio of effort to results. The goal is to improve visibility and leads measurably.
The consultants support implementation, train the team and measure the results. Unlike a pure digital marketing agency, the focus is on the decision, not on execution. The result is a plan based on data.
Digital marketing agency or digital marketing consulting: which fits better?
Digital marketing consulting works strategically: it delivers goals, priorities and know-how, while implementation stays in-house. A digital marketing agency also takes over implementation.
Consulting is often the first step, followed later by individual implementation tasks. digitalagenten supports both phases as a consulting agency for digital marketing. The form of collaboration comes from four models.
When is an online marketing consultant worthwhile?
An external online marketing consultant pays off when a lot is implemented in-house but the overview of what works is missing. Typical occasions are a relaunch, falling rankings, rising costs for paid campaigns, a new market or the question of how AI assistants present your brand.
The consultant brings an outside view, experience from more than twelve years and industry benchmarks. They show exactly what pays off. For strategic decisions, consulting and implementation come from the same digital marketing agency. The consultants are happy to discuss your starting point in the initial call.
How does digital marketing consulting work?
In four steps. First step: initial call and target picture. Second step: audit and benchmark to analyze website, channels and competitors.
Third step: strategy workshop to define priorities, budget and responsibilities. Fourth step: implementation by your team or with the agency, accompanied by reporting that makes results visible in every cycle and helps optimize every measure.
How is a cross-channel digital marketing strategy developed?
From goals, target groups and data. First, we clarify which customers you want to win and where they search: on Google, in AI assistants, on LinkedIn or in newsletters.
Then digital channels are connected so that SEO, GEO, paid media and email marketing reinforce each other and the right channels work at the right time. A successful cross-channel plan defines exactly which channel takes on which task in the customer journey, how the budget can be used in a targeted way and how success is measured.
How do you recognize a good digital marketing agency?
Good digital marketing agencies first understand the business model and the needs of their clients before recommending solutions. They show case studies and references from the industry, disclose costs and services and measure success by leads and revenue instead of clicks.
Professional agencies explain their recommendations clearly, bring expertise, proven strategies and pragmatic solutions and work with fixed points of contact. A good service provider also tells you exactly what does not pay off. Collaboration is successful when both sides measure the same goals. A free initial call helps you find the right digital marketing agency.
Recommendations at digitalagenten are based on own measurements across client projects and on published documentation and research from Google and leading SEO tools.
