Google Tag Manager Consultant

With tag management systems you can implement multiple third-party tags (e.g. Google Analytics, Facebook pixel, Google Ads) on your website quick and easy. Google Tag Manager is the most widely used Tag Management System and free in its standard version.

I am a Google Tag Manager consultant and I plan and implement tag management systems for my clients.

Through GTM, I deploy tracking setups integrated with third-party tags that scale over multiple websites and languages.

It enables you for example to use user interactions from your Google Analytics account to create user segments for ad campaigns on Facebook Ads, Doubleclick or Linkedin.


As a freelance Google Tag Manager consultant, I offer the same services (or more) as a typical digital marketing agency. You save time and budget since the communication is directly with the GTM expert. No project management and administration overhead cost.

Here a short list of my Google Tag Manager consulting services:

  • planning and implementation of Google Analytics setups
  • campaign coordination with media and web agencies
  • event tracking
  • enhanced eCommerce tracking
  • data layer implementation
  • cookie banners
  • data integration across tags
  • retargeting with e.g. Facebook, Google Ads, Twitter, Linkedin
  • goal conversion tracking
  • affiliate tracking
  • campaign tracking
  • video tracking
  • Data import and export
  • debugging and troubleshooting
  • custom tag solution with JavaScript

These configurations can be deployed and changed quickly via Google Tag Manager (GTM) or any other tag management solution. GTM evolved as a standard for managing data, marketing tags, analytics and marketing services primarily because a GTM account is free and works reliably.

Since its release, marketers can finally execute and adjust their digital campaign strategy very flexibly since no changes in the source code are required.

What is Google Tag Manager?

Google Tag Manager is a tool to implement and configure tags on a website. You can define rules for the execution of each code snippet and define exactly which data it has access to.

Everything is done from the user-friendly Google Tag Manager interface, which delivers a quick and snappy developer experience. Implementing new tags through a graphical user interface (GUI) in itself is a welcome new experience, because it requires less concentration and saves implementation time.

Google Tag Manager is essentially a container tag through which you can implement all other tags on your website. Only the GTM container goes into the source code and the remaining code snippets can be implemented and configured at scale from the Google Tag Manager account.

Through its flexibility, it grew very popular for online marketing and data management, especially with Google products. Google Analytics tags that share data with advertising services (e.g. Facebook, Google Ads) are typical use cases.

What are the benefits of Google Tag Manager?

The main benefit of Google Tag Manager is the quick and flexible deployment of tags and the scalable data management among them.

These comparably small implementation changes cost time and add up for clients that run many digital campaigns. Good programmers are expensive and agencies have limited resources. Therefore it makes sense to outsource tag implementation tasks to a tool with a graphical user interface (GUI) and faster deployment time.

Why do you need Google Tag Manager consulting?

A GTM consultant plans the Google Analytics implementation and makes sure that other marketing services get the right data about e.g. campaign visits and conversions to optimize your segments.

If you run many campaigns with individual landing pages, a GTM specialist will get conversion tracking added to the analytics reports fast.

By tracking the events on your landing page, you can check the ongoing performance of your campaigns. If the campaign doesn't perform as expected, you will notice it early on and can re-adjust. This feedback-cycle for each campaign brings along learnings to optimize future campaigns.

A Google Tag Manager expert also acts as a developer in your marketing team and helps with tagging, JavaScript tasks and custom solutions around your site.

GTM consulting is increasingly important for clients that rely on other digital marketing services for their business. It maximizes the value of each page view with high quality engagement data about SEO, email and retargeting campaigns to help you optimize your ad spend.

How much does GTM Consulting cost?

My freelance rate is 120 per hour net. If I am to plan a Google Analytics implementation for a client, I estimate the scope of work and send a proposal outlining all deliverables. The scope is dependent on the size of the website and the amount of KPIs that should be tracked.

The website's underlying technology also plays a role in terms of ease of implementation. Google Analytics setups with event tracking and 3rd-party data integration cost between 1800€ and 6000€ net.

If you need continuous Google Tag Manager help for a larger site, a monthly retainer budget according to the expected workload can be agreed upon. Monthly retainers should account for a minimum of 10hrs per month.

Smaller tasks are charged with a flat fee between 100€ and 300€.

My profile

I built my first website when I was 14 years old, to trade movies with my classmates. With 18, I started running an e-commerce shop for table soccer called "Kickerkult". When I got more into Analytics tools, SEO and ran my first newsletters, I was hooked with the web. Since then, I wanted to focus my career on the internet.

I worked in digital agencies since 2011 and focused solely on SEO and Analytics since 2014. I built tag management systems with GTM for e-commerce sites, supermarket chains, car manufacturers, restaurant chains, insurance companies and many other sectors. My clients tend to be enterprises, large companies or they somewhat reflect a similar organization and procedures internally.

I work self-employed as a Google Tag Manager freelance consultant since 2018. I also do search engine optimization and analytics consulting. All out of one hand.

My personality is analytical, rational and pragmatic. I like analysis to find the right solution, but also don't want to have things complicated. Hence, me stepping out of the hectic agency to work for myself as a GTM freelancer was a logical consequence.

To keep my know-how up to date with Tag Management, Analytics and SEO, I run a few websites and visit conferences. I also co-organize the Copenhagen SEO-Meetup.
