Server-side Tracking 2.0Optika Anda.
A proposal shaped around an external tracking audit of optika-anda.com. Server-side tracking on dedicated EU infrastructure, multi-platform CAPI, German bare metal. The same standard of precision your poliklinika delivers to every patient, applied to your marketing data.
There is no enterprise trackingon shared infrastructure.
Wascer enables and secures private data infrastructure in the EU for your user data tracking. This ensures the best alignment with compliance while enabling historic cookie storage for every website visitor. Most marketing tracking on the EU market rides on multi-tenant infrastructure on Google Cloud or Scaleway. The same shared model your compliance team would reject for production data.
Your tracking scores 42/100.Here's the 56 points left on the table.
Before writing a line of this proposal, we ran optika-anda.com through an independent third-party tracking checker. The 42/100 score sits below the local category leader optika-kobacic.hr (83/100). Each recommendation below maps directly to the Wascer Enterprise delivery plan.
The audit estimates ~51,877 monthly users and ~€5,740 in paid ad spend for optika-anda.com. Due to ITP and ad blockers, some campaign results aren't attributed in your analytics or ads campaigns. Server-side tracking helps improve attribution, recover lost conversions, and track users accurately.
Inflated top-funnel, distorted conversion rate.
Optika Anda's pixel 641353823045947 is implemented client-side. PageView fires duplicated on most page loads (Meta's own diagnostic flags: 'Event fired 2 times with identical data, which can cause tracking errors'). The result: Meta receives an inflated count of top-funnel impressions, while conversions land at the real volume. Conversion rate calculated against this denominator is distorted, and the ~31 active campaigns optimize against a signal that does not reflect reality.
Server-side CAPI with end-to-end deduplication is the smallest fix. Pixel infrastructure is already in place.
Every channel you run.One certified stack.
Wascer is a Google Partner and an accredited implementer across the full server-side tracking ecosystem. The same platforms already active in your GTM container. No third-party plug-ins, no grey-area middleware: every CAPI integration below is first-party, supported directly by the platform's own API.
Direct API integrations only. Every event from events.optika-anda.com is delivered to each platform via its own Conversions API. No resellers, no shared proxies, no data leaving the EU for processing.
Client-side is a browser.Server-side is your infrastructure.
This is the difference that the audit findings cannot solve alone. Even with perfect event architecture, data still has to leave the browser, and today's browsers strip it aggressively.
No hand-waving.Every number below has a citation.
We removed anecdotal client stories and replaced them with benchmarks from Meta's own documentation and published studies by Triple Whale, Madgicx and TrackBee. Each card below lists the source. The actual deltas for Optika Anda will be measured in week 1 of the build and reported transparently.
Same channels.Clean signal across every one of them.
Optika Anda runs Google Ads and GA4. Server-side infrastructure upgrades the tracking of each channel independently, without requiring any channel migration, strategy shift, or team reorganisation. Every platform receives the same unified business event, enriched with first-party data, deduplicated end-to-end.
German bare metal.Dedicated, contractual, EU-only.
Six layers, one provider, one jurisdiction. Every block below is dedicated, contractual, certified at the source.
Dedicated Hetzner cluster · Falkenstein
Bare metal. Not shared VMs. Zero noisy neighbours. AMD EPYC, NVMe storage, ECC RAM, hardware-isolated for Optika Anda.
Cloudflare edge · 330+ cities · 125+ countries
~50ms from 95% of internet users. NAT with dedicated egress IPs. Anycast routing keeps every visitor on the closest PoP.
Cloudflare WAF · DDoS · bot mitigation
Enterprise firewall. Request filtering at the edge before traffic reaches your container. Bot scoring on every event.
Argo Smart Routing · 500+ Tbps backbone
Private fibre network. Lowest-latency path measured at ingress, not just at the edge. Live re-routing around congestion.
Germany only · contractual
GDPR Art. 28 DPA. German court orders only. No CLOUD Act exposure. No US backbone transit. No data leaves the EU at any point.
Dedicated CS · priority support
Named Customer Success on your account. Priority response via WhatsApp and email. 99.9% uptime SLA, monthly availability report.
The single-platform tier is Meta-only.Ours covers every platform you run.
Like-for-like comparison at the same monthly tier. Other vendors offer multi-platform Signals Gateways and sGTM hosting at different tiers. At the equivalent CAPI Gateway tier specifically, scope is strictly Meta. Wascer Enterprise at the same tier covers every platform Optika Anda runs today.
Three pillars. No shortcuts.
Enterprise server-side tracking is not a tag install. It is three coordinated layers: infrastructure, privacy, attribution. Each one fails in isolation.
Dedicated EU infrastructure
Private GTM Server-Side cluster on Hetzner Falkenstein. Custom loader, antiblock, Cloudflare WAF, NAT with dedicated IPs, Argo Smart Routing. Every layer is yours.
Privacy-first architecture
GDPR compliant by construction. First-party cookies under your domain. Cookie Keeper extends lifetime to 90+ days. DPA under Art. 28 GDPR. Germany-only data residency, contractually guaranteed.
Unified multi-platform attribution
GA4 Measurement Protocol · Meta Conversions API · Google Enhanced Conversions · LinkedIn CAPI · TikTok Events API. One event fires, every platform receives it clean, deduplicated.
30 days to clean the stack.30 more to scale it server-side.
A deliberate two-step delivery. First we fix the foundation, every event, every platform, 99% accuracy. Only then do we build server-side infrastructure on top of something we know is clean. No blocking dependencies inside either phase.
Tracking & Events Fix
Full audit, fix and documentation of every existing event across GTM, GA4, Google Ads and the consent layer, on optika-anda.com. We finish this phase with a verified 99% accuracy baseline before any server-side work begins.

What realistically changesfor Optika Anda.
We separate what is technically guaranteed by the architecture from what depends on your campaigns, creatives and market. Both are listed openly below.
Clean, unified event architecture
Every event from the audit, fixed end-to-end. One event, every platform. No duplicates. Parameter-driven segmentation. Delivered in two 30-day phases.
First-party cookies · 90+ day lifetime
Technical feature of Cookie Keeper on first-party domain. Critical for considered B2C journeys where Safari ITP today caps attribution at 7 days.
Multi-platform server-side delivery
GA4 Measurement Protocol, Meta Conversions API, Google Enhanced Conversions, LinkedIn CAPI, TikTok Events API. One event fires from your domain to every platform, deduplicated.
German residency · GDPR-native stack
Data stays on Hetzner Falkenstein. Art. 28 DPA. Germany-only court access. Zero CLOUD Act exposure. A talking point for your own poliklinika clients, not a liability.
Recovery of previously-lost conversion signal
Industry benchmarks show 20-40% signal recovery after server-side migration. Your actual recovery will be measured in week 1 parallel tracking and reported honestly.
Stronger algorithm optimization over time
Cleaner signal historically leads to lower CPA and faster learning on Meta and Google. Magnitude depends on baseline, creative, audience. No number promised.
