Engineered growth systems
Growth rarely breaks because of one channel. It breaks when visibility, acquisition, and measurement stop working together.
We build and run the system that connects them.
A 30-minute conversation to map where your growth system has gaps. No pitch. No obligation.
Case studies
Two problems we were called in to solve
Both started the same way: the obvious explanation was wrong, and the real cause was one layer below where anyone was looking.
SEO recovery · Media
A 90% traffic collapse with no change in the content
Large Greek news publisher, 650,000 articles, anonymised at the client's request
Three Google updates took the blame, but the content mix had not changed since the site's peak. The audit found a sitewide nofollow rule with eight commercial domains written into its exclude list, affecting an estimated 330,000 pages. The links were visible in the HTML. The configuration that turned them into a scheme was not, which is why no crawl had flagged it.

Latest quarter against the bottom of the collapse. Gains off the floor, not a return to the previous peak.

Platforms optimising for the wrong customer
EKEK Athina, in partnership with the University of Patras. Performance marketing client since 2021
An already-optimised account. Roughly 85% of applications arrived with no click ID, and the paid enrollment happened offline one to two weeks later. Google and Meta could see the lead. They could not see the student. We rebuilt the measurement layer underneath and sent confirmed enrollments back to both platforms.

We work with growth-stage teams that have outgrown fragmented execution.
Why teams come to us
Organic visibility has stalled.
Paid media is not translating into enough pipeline.
Reporting is inconsistent and decision-making is running on incomplete data.
Where we fit
We are a strong fit for organizations that value clarity, accountability, and informed challenge.
If you are looking for the cheapest provider or a fixed package with no strategic involvement, we are probably not the right fit.
If you want a team that looks beyond channel performance and focuses on the business outcome, let's talk.
Search, paid media, and attribution — run as one system
Our work is structured across search, paid media, and attribution, supported by the technical infrastructure that keeps performance measurable, adaptable, and tied to real business outcomes.
Search Visibility (SEO & AI-driven search)
We help brands recover lost visibility, identify what drives commercial impact, and build search strategies designed to perform across both traditional SEO and AI-driven search environments.
Not just rankings. Real pipeline from search.
Performance Marketing (paid media)
We run paid media with disciplined testing, precise measurement, and tighter control over where budget creates value. Campaigns are built to support pipeline, not just produce platform metrics.
Every euro is tracked. Budget flows toward what works.
Analytics & Attribution
We build attribution pipelines that connect qualified leads, purchases, subscription events, and other key business signals back to the channels that influenced them.
Better measurement. Better decisions. Better optimization across the funnel.
The infrastructure layer
Behind the work is the technical layer that keeps everything connected. This is not an add-on. It is the layer that turns channel execution into a learning system.
For design, copy and campaign storytelling, we work with trusted creative partners who share our performance-first mindset.
Built by marketers who also code, analyze, and stay accountable for the result. We don't outsource responsibility. We take it personally.
How We Compare
In-house teams
We work alongside internal teams and strengthen the areas where measurement, search visibility, or paid performance need deeper support. We do not replace internal capability. We connect it.
Traditional agencies
If you need channel execution without technical depth or attribution work, there are many options. We are usually brought in when that model has stopped being enough.
Freelancers
Freelancers can be excellent for narrow execution. We are a better fit when the challenge crosses channels and needs tighter connection between strategy, measurement, and performance.
Disconnected reporting setups
Many teams already have dashboards. The issue is rarely access to numbers. It is whether the right signals are reaching the places where decisions and optimization actually happen.
Why Partnerships Last
Most of our clients have been with us for more than five years.
That is not an accident. Compounding requires consistency. A system that improves every quarter is worth more than a campaign that wins once.
We invest every year in top-tier training and Europe's leading industry conferences so decisions stay fast, clean and current.
You always know where things stand, what is changing, and what comes next.
Across different business models

A Google penalty collapsed visibility across Search, News and Discover overnight. Within eight months of structural recovery work:
"Datafunc turned a penalty crisis into growth. Their SEO and strategic thinking pushed us far beyond recovery, they built a stronger foundation for real visibility."
GoLearn
Fragmented acquisition, unclear attribution, rising costs. Five years of connected growth work across tracking architecture, full-funnel paid media and analytics infrastructure.
"Datafunc has been our data analytics and digital marketing partner since 2019.

We consistently grow with over 60,000 graduates a year, providing a variety of e-learning courses."
NKUA e-Learning
International campaigns burning budget without proportional results. Stronger measurement and restructured acquisition changed the economics entirely.
"Working with Datafunc was a great experience.
The team was friendly, professional, and always willing to go the extra mile to help us learn new things in digital marketing and achieve our goals. They not only exceeded our expectations, but also made the entire process enjoyable and stress-free.
I highly recommend Datafunc to anyone seeking a knowledgeable and reliable digital marketing partner."
Logopaizoume
Local discoverability and paid media working in isolation. Connected and rebuilt as one system.
"After working with Datafunc for one year, I have nothing but positive things to say about the level of service, consistency, and efficiency they provide.
From the start of our cooperation, they have been honest and reliable partners, inspiring trust that they’ll always do their best. Since Datafunc has taken over my business’s digital marketing, we have significantly increased our clientele and experienced growth of 5X."
