Your marketing data is probably wrong.

About Datamentari

“Data” for measurement. “Mentari” is Malay for sun. We reveal what marketing data actually says by burning away the fog of bad tracking, inflated reports, and broken configurations.

The gap between reported and real is where marketing budgets go to die.

Every week we audit businesses that trust their analytics completely. They decide where to spend, what to cut, which campaigns work. Nearly every time, the data behind those decisions is structurally broken. Not slightly off. Fundamentally wrong.

Default GA4 configurations track pageviews and almost nothing else. Browser-based tags get blocked by Safari, Firefox, and every major ad blocker. Cookie lifespans that platforms promise are quietly cut to 7 days by Intelligent Tracking Prevention. The numbers in your dashboard look precise. They are not.

We are not an agency. We are not a SaaS tool. We are a measurement specialist. The person you call when you suspect your numbers are wrong, or when you need the infrastructure that makes them right.

The numbers behind the problem.

What we see across our marketing analytics audits.

~30%

Invisible conversions

Client-side tracking misses roughly a third of conversions from users with ad blockers or restrictive browser settings. Those sales happened. Your analytics never recorded them.

4 in 5

Default-only event tracking

The majority of GA4 setups we audit rely entirely on default “enhanced measurement” with zero custom event configuration. Scroll tracking is on. Purchase tracking is not.

2x+

Platform over-reporting

Ad platforms routinely over-count conversions compared to server-side validated data. Your “best performing channel” may be taking credit for conversions it did not drive.

Most agencies won’t tell you this because it makes their reports look bad.

What We Build

06 Capabilities
Infrastructure
01

Server-side tracking

Move data collection from the browser to a server you control. Server-set first-party cookies bypass Safari’s 7-day ITP limit, extending attribution windows to 90 days or more. We also configure custom identifier recovery to recapture conversion data that would otherwise be lost when browser cookies are blocked or expire.

Google Tag Manager / Server-Side GTM / First-Party Cookies / Consent Mode v2
02

GA4 configuration

Custom event taxonomy built around your business model. Form submissions, WhatsApp clicks, phone calls, purchases. Every event named, parameterised, and mapped to a conversion that matters to your bottom line.

GA4 / Custom Events / Enhanced Conversions / Data Streams
03

Conversion tracking

End-to-end conversion infrastructure across Google Ads, Meta, TikTok, and LinkedIn. Server-side event delivery, deduplication so conversions are not double-counted, and value-based bidding signals that reflect actual revenue.

Cross-domain tracking

Maintain user identity across multiple domains, subdomains, and checkout platforms. No more broken sessions when users move between your marketing site, app, and payment gateway.

Attribution and UTM framework

Clean UTM taxonomy across every channel with naming conventions enforced at the source. Cross-platform attribution that accounts for the real customer journey instead of last-click guesswork.

UTM Governance / Data-Driven Attribution / Channel Grouping
06

Multi-platform reporting

Unified dashboards that reconcile data from GA4, ad platforms, CRM, and backend systems. One source of truth with server-validated numbers your finance team can actually sign off on.

The Difference

Standard setup versus full implementation.

Most businesses run default settings and think they are covered.

Standard Setup

Default GA4 with no custom configuration

Pageviews only. No conversion event tracking.

Client-side tags. Up to 40% data loss from blockers.

No UTM governance. Inconsistent campaign tagging.

Siloed platform reports taken at face value.

Sessions break across domains and subdomains.

Full Implementation

Custom event taxonomy for your business model.

Full funnel. Forms, clicks, purchases, calls.

Server-side tracking. Ad-blocker resistant.

UTM framework with naming conventions enforced.

Unified reporting. One source of truth.

Seamless cross-domain user identity.

How We Work

From broken tracking to infrastructure you can trust.

Every engagement starts with a free audit. If there is a fit, here is what the full project looks like.

Step 01 ยท Free

Audit

We review your site, your tag setup, and your data layer. You receive a scored report with a letter grade, annotated screenshots, and a prioritised gap list. Then we walk through it together in a 15-minute call.

This is the free audit. You get the report and the call regardless of whether you choose to work with us. No obligation.

Step 02

Plan

If you decide to move forward, we build the implementation plan. Event taxonomy, tag architecture, server-side requirements, consent framework. You see exactly what gets built before any work begins.

You get: A walkthrough of the full plan covering what gets tracked, how, and in what order.

Step 03

Build

We configure Google Tag Manager, GA4, server-side GTM, ad platform pixels, and custom events. Cross-domain linking. Server-side pipelines. Everything configured, tested, and live on your site.

You get: Complete tracking infrastructure in production, plus a knowledge transfer session so your team understands what was built and why.

Step 04

Verify

End-to-end QA across devices, browsers, and consent states. Data validation against real transactions. We do not hand off until the numbers match reality.

You get: Confirmed data accuracy, plus a 30-day monitoring window to catch edge cases as real traffic flows through the new setup.
