The real problem
Five providers. Five opinions. And when the numbers don't materialize, nobody is accountable.
Here, marketing, IT and automation come together in one place — with one point of contact, one fixed price and numbers to prove it.

Service 01 · Marketing
Win more clients
Many businesses spend on advertising without knowing which euro actually brings inquiries. I build your marketing so every measure contributes measurably to revenue — from the first ad to the qualified inquiry in your inbox. Clear numbers per channel.
Performance & paid ads
Google, Meta & LinkedIn, optimized for inquiries and revenue instead of clicks. You see, per channel, what a lead costs and what it returns.
Social media & content
Editorial planning, creatives and ongoing profile upkeep. Automated tools handle much of the routine — from topic planning to drafts; I steer strategy and sign-off so posts turn into inquiries.
Web & analytics
Fast, conversion-focused websites with clean tracking (GA4, Consent Mode). You see which campaign brings inquiries — and which only costs budget.
Strategy & consulting
Positioning, funnels and budget where they actually work — decisions based on real numbers, not gut feeling.

Deep dive on service 01 · Analytics & AttributionNew
Every platform grades its own homework. I run the numbers.
Meta, Google & Co. all claim the same purchase — platform last-click systematically double-counts. I build the measurement behind it: multiple attribution models in parallel, incremental impact instead of face-value ROAS, a new-customer split at order level, and reporting that delivers itself every week.
Attribution & incrementalityServer-side tracking & Consent Mode v2Automated reporting
01
Multi-model consensus over platform truth
First-click, last-click, linear and position-based run side by side; decisions are made on the median — not on the ad platform's self-assessment. Where the models disagree, that's a finding, not a measurement error.
02
Incrementality & budget decisions
The question is never “what's the ROAS?” but “what happens at 20% more budget?”. Marginal ROAS with confidence intervals, saturation detection and clear scale/hold/cut/test recommendations — transparently derived, with final sign-off by a human.
03
Marketing mix modelling: the second opinion
Cookies are dying, iOS blocks, consent thins out the data — MMM works on aggregated data instead of user profiles: what does each channel really contribute to revenue, including brand, season and organic? The tracking-independent cross-check on attribution.
04
New-customer truth: NC/RC split & CAC
Revenue is not growth. I separate new from returning customers at order level (24-month lookback) and steer every channel by what it actually delivers: new customers — and at what cost.
05
Tracking forensics: when the numbers lie
The most expensive mistakes aren't on the dashboard — they're underneath it. I find broken pixels, silent server-side UTM rewrites and over-reporting spend connectors, and build measurement paths that survive them.
06
AI-powered anomaly detection
Nobody stares at eight dashboards every morning. AI checks screen spend, conversions and tracking signals against the expected corridor every night — and flag outliers before they cost budget: the silent CPM creep, the duplicate tag, the collapsed conversion rate. AI flags and explains; humans decide.
The technical foundation: Server-side tracking instead of dying browser pixels, Consent Mode v2 for GDPR-clean data, every channel with orders and costs in one central data model — and dashboards that refresh themselves weekly instead of month-end Excel work.
Server-Side tracking
runs through your own server — robust against ad blockers, iOS limits & cookie deprecation

Service 02 · IT & Automation
Work with more calm
When technology gets in the way, it costs time and nerves every day. I make sure your IT simply works — secure, up to date, and relieving you of recurring tasks. So your team focuses on the work, not on disruptions.
Networks & security
Stable networks, a firewall and a backup concept that holds up when it matters — so an outage doesn't turn into a standstill.
Microsoft 365 & SharePoint
Microsoft 365, SharePoint and Teams set up cleanly, sensibly structured and secured. Work from anywhere, without the data chaos.
Data migration & workstations
Moving data and workstations with no downtime — your team carries on the next morning as if nothing had happened.
Recurring tasks automated
Routine that eats time — sorting inbox, pre-qualifying inquiries, preparing replies — is handled in the background by automated processing. Sign-off always stays with you.

„If I can't measure it, I won't sell it to you.“— Lars Huismann
I'm Lars Huismann — Performance Marketing Consultant and founder of Huismann Marketing Solutions in Berlin. For 15+ years I've connected what most providers keep separate: measurable marketing and the IT behind it. Starting with systems integration and networking at the German Bundestag, through performance roles at Image-Line Software, FinCompare, MoBerries and Brandpunkt — today at Huismann Marketing Solutions with fixed prices and every service from one source.
At Huismann Marketing Solutions you get exactly what's on the services page — as clear deliverables, not buzzwords: performance & paid ads (Google, Meta, LinkedIn) aimed at inquiries and revenue. Web & analytics with GA4, GTM, Consent Mode and BigQuery, so you see per channel what a lead costs and what it returns.
Plus IT and automation from the same source: Microsoft 365 and SharePoint cleanly structured, network and security without downtime, migrations without nasty Monday surprises. For property managers I set up casavi, Impower and Neovaro and add GDPR-compliant pre-sorting — with the final sign-off staying with you.
