Online marketing agency: the essentials at a glance

What an online marketing agency does

Definition

An online marketing agency plans, manages and implements the measures that help a company get found and receive enquiries online. This includes organic search (SEO), paid ads in search engines (SEA) and on social networks (Paid Media and Social Media) and, for a few years now, visibility in AI answers (GEO).

The difference from a specialised single-channel agency lies in the management: the channels are coordinated with each other, measured together and prioritised by impact. The collaboration is led by a dedicated contact person who knows the project’s goals, market and numbers.

Semtrix as an online marketing agency

From search engine marketing to social channels, everything at Semtrix runs through one team, as a full service: we don’t just advise, we implement, right through to the changes on your website.

Since 2015, Semtrix has delivered more than 1,500 client projects. Around 40 experts in Germany work on strategies for start-ups, mid-sized companies and major brands. More about us, examples in our references.

Services working together

We bring together search engine marketing with SEO and SEA, plus Paid Media, Social Media and AI visibility (GEO), under one roof. Each area can be booked on its own, but reaches its full impact in combination.

Looking for one discipline in full depth? Find it at our SEO Agency, SEA Agency and GEO Agency.

GEO: AI visibility as a discipline of its own

Search is changing. People increasingly ask ChatGPT, Perplexity, Gemini and Google’s AI Overviews. GEO makes sure your brand is mentioned, cited and recommended in these answers - an independent discipline of equal rank, with its own GEO/LLM tracking tool.

We took GEO seriously before it became an industry trend - the European Search Awards 2026 jury noted it explicitly.

How to recognise a good online marketing agency

The market is confusing, and most providers sound the same. Check these five points before hiring an agency.

  • It shares numbers that can be verified. Results with a client name, time period and starting point say more than a percentage without context.
  • You know your contact person by name. Not a ticket system, not a rotating pool.
  • It explains how it measures success. Rankings alone are not a result. Enquiries, leads and revenue are.
  • It tells you what it can't do. Anyone who promises position 1 is promising something out of their hands.
  • It doesn't just offer AI search, it measures it. Whether a brand appears in ChatGPT or AI Overviews can be tracked. If you don't measure it, you can't manage it.
Your benefits with Semtrix

The difference between scattered individual measures and effective online marketing lies in integration and management. With Semtrix, you benefit from:

  • Everything from one source: SEO, SEA, Paid Media, Social Media and GEO work together, without anything getting lost between multiple providers.
  • Dedicated experts at your side: one specific contact person who knows your goals, your market and your numbers.
  • Data-driven management: the Eskimoz Group's in-house tools make the most effective levers visible and easy to prioritise.
  • International reach with local proximity: 250 consultants and project experience in 10 languages, with support from Germany.
  • Measurable results: we measure success by qualified enquiries, leads, sales and revenue, transparent and easy to follow.

FAQ

Frequently asked questions for an online marketing agency

What does an online marketing agency do?

An online marketing agency plans and manages the measures that help a company get found and receive enquiries online: organic search, paid ads, social networks and visibility in AI answers, plus the implementation of all of it.

How much does working with an online marketing agency cost?

That depends on the scope: the number of channels, competitive pressure and the state of the website. With us, the analysis is free, and the offer follows afterwards, listing every item individually.

How long does it take for online marketing to work?

Paid channels deliver the first data within a few days. SEO and GEO take longer, several months depending on the starting point. That's why we start with a 90-day roadmap combining both.

Do I need all five disciplines?

No. Each one can be booked on its own. The diagnosis shows which channels work for your market. It often makes sense to start with two and expand later.

What is the difference between GEO and SEO?

SEO makes sure your website is found in classic search. GEO makes sure your brand appears in AI-generated answers. The two disciplines complement each other but use different methods and metrics.

Does Semtrix work internationally?

Yes. As part of the Eskimoz Group, we work with 250 consultants in five countries and ten languages. Project management stays with your dedicated team in Germany.

Who looks after my project?

A dedicated contact person from the Search or Paid Media team, named before the start and staying the same for the entire term.

Where is Semtrix based?

Semtrix is part of the Eskimoz Group, with its own offices in five countries. Addresses are in the footer; meetings are possible on site or online.

From search engine marketing to social channels, everything at Semtrix runs through one team, as a full service: we don't just advise, we implement, right through to the changes on your website. You don't get an off-the-shelf solution, but a strategy that fits your website, your market and your goals.

Since it was founded in 2015, Semtrix has delivered more than 1,500 client projects. Around 40 experts in Germany work on strategies for start-ups, mid-sized companies and major brands. As part of the Eskimoz Group, named “Best Large Integrated Search Agency” at the European Search Awards 2026, we combine local support with international reach. More about us, examples in our References.

Services working together

We bring together search engine marketing with SEO and SEA, plus Paid Media, Social Media and AI visibility (GEO), under one roof. Each area can be booked on its own, but reaches its full impact in combination: more visibility, more qualified clicks and measurably more revenue. Because everything runs through one team, nothing gets lost between multiple service providers and there is no second invoice.

If you are looking for a single discipline in full depth, you will find it at our SEO Agency, SEA Agency and GEO Agency. For companies with target markets outside Germany, there is our international SEO agency.

GEO: AI visibility as a discipline of its own

Search is changing. People increasingly ask their questions to ChatGPT, Perplexity, Gemini and Google's AI Overviews. GEO (Generative Engine Optimization) makes sure your brand is mentioned, cited and recommended in these answers. At Semtrix, GEO is not a subcategory of SEO but an independent discipline of equal rank, with its own methods and its own GEO/LLM tracking tool that makes AI visibility measurable.

We took GEO seriously before it became an industry trend. The jury of the European Search Awards 2026 explicitly mentioned the Eskimoz Group's early GEO focus in its reasoning.

How to recognise a good online marketing agency

The market is confusing, and most providers sound the same. You can check these five points before hiring an agency, without expert knowledge and without a trial phase.

  • It shares numbers that can be verified. Results with a client name, time period and starting point say more than a percentage without context.
  • You know your contact person by name. Not a ticket system, not a rotating pool.
  • It explains how it measures success. Rankings alone are not a result. Enquiries, leads and revenue are.

  • It doesn't just offer AI search, it measures it. Whether a brand appears in ChatGPT or in AI Overviews can be tracked. If you don't measure it, you can't manage it.
