Why Work with a Data Agency?

Let’s talk!

Data Marketing Consulting

In today’s digital era, data is essential for businesses looking to understand their market, anticipate trends, and make informed decisions.However, structuring data properly, understanding the variety of tools available, and staying compliant with evolving regulations can make implementation complex.That’s where a Data Agency plays a crucial role — bringing in specialized expertise to unlock the full potential of your company’s data.

Technical Data Support

The growing number and specialization of platforms require the support of experienced professionals.KLH remains tool-agnostic and relies on a team of consultants covering the full ecosystem of available platforms (TMS, Web Analytics, CMP, A/B Testing, CDP, etc.).Our consultants bring both their technical skills and strategic insight, always with one goal in mind: driving your performance.

Data Marketing Training

We believe that a strong client relationship goes both ways.Sharing knowledge is key to helping brands go further, and training is a cornerstone of that process.We support brands in taking ownership of their tools, reducing their dependency on agencies, and enabling deeper discussions around data and strategy.

The Key Stages of a Full Data Project

step 1
Defining
Your Needs
KLH supports you in identifying your key KPIs and understanding your digital ecosystem, in order to recommend the most effective technical solutions and a data architecture tailored to your objectives.
step 2
Tracking Implementation
From drafting your tagging plan to full implementation, we ensure the quality and accuracy of your tracking setup — and its proper integration across all the platforms you rely on.

While Google Tag Manager is the most commonly used TMS among our clients, our expertise also covers other market-leading solutions such as Tealium, Adobe Launch, Piwik, and more.
step 3
CRO Audit
We work with you to define the objectives of the analysis — or start from a blank slate when needed — to uncover the key pain points in your user journey and identify high-impact optimization opportunities.
step 4
A/B Testing
Not sure which A/B testing solution best fits your needs (usage frequency, cost, features, platform integrations)? We’re here to guide you.

Our team supports you throughout the process to simplify your experience with A/B testing tools and deliver the most refined and impactful experience to your users.
step 5
The End Goal
Our ultimate objective: to help you gain a deep understanding of your users’ journey and define a clear, actionable roadmap to guide your next steps.
