OUR SERVICES
10+ Years of Experience. One Goal: Better Results.
Our GA4 & Tracking Services Include
What we hear
What we do
Full GA4 property and GTM container review, data layer structure and quality assessment, event, conversion, and parameter validation, cross-domain and session continuity checks, and data accuracy reconciliation against source systems.
What we hear
What we do
Direct gtag or Google Tag Manager setup — whichever fits your stack — plus a fully documented custom event taxonomy built around GA4’s standard naming, not guesswork. Includes WooCommerce/Shopify ecommerce funnel tracking (view_item → add_to_cart → begin_checkout → purchase), lead-form tracking across your existing form plugin, and Consent Mode v2 configuration for GDPR and CCPA compliance. Every event is verified live in DebugView before we hand it back to you. When your own developers are building the dataLayer, we hand them exact event and parameter specs — not a generic GA4 doc — and review their implementation against it before anything ships.
What we hear
What we do
Server-side tagging via Google Tag Manager server containers, cross-domain and subdomain tracking for multi-property setups, first-party data collection to reduce ad-blocker and ITP data loss, and consolidated multi-brand or multisite GA4 architecture for agencies and franchises managing several properties at once.
What we hear
What we do
Custom GA4 Explorations and dashboards built around the KPIs your team actually reports on — not GA4’s generic defaults, including funnel exploration reports that show exactly where visitors drop off between each step. Looker Studio reports built and connected directly to your GA4 property, so stakeholders see live numbers without logging into GA4 itself. Monthly data-health checks to catch tracking drift before it corrupts a quarter of reporting, and a living documentation file your team (or your next developer) can actually read.
What we hear
What we do
Monthly analysis of your GA4 data — where visitors drop off in the funnel, which channels and segments convert best, and which pages are quietly bleeding conversions — delivered as a short, prioritized list of what to test or fix next, not a wall of charts.
Retainer or a Monthly block of hours, & Flexible Models to choose from. Fixed-scope pricing is also available for well defined projects.

I can’t imagine any other companies out there in a similar situation where we are that couldn’t benefit from the services that Brillmark offers.

Finding competent professionals to bring conversion research ideas to life and deliver results for clients without breaking their websites was challenging – until I found Brillmark. Abdullah and his team are a group of technical A-players with whom anyone serious about CRO and experimentation should work. I’ve collaborated with them on multiple projects, and they consistently prove they’re the real deal

Case Studies
GA4 Tracking Audit
We identified duplicate ecommerce events caused by overlapping Shopify and GTM tracking. We traced each implementation, removed unnecessary tracking, and validated the final GA4 setup.

Conversion Tracking & Debugging
We traced critical conversion events from the website and dataLayer through GTM and GA4, identified tracking gaps, implemented the required events, and validated the complete flow.

Consent & Analytics Compliance
We identified tracking firing before the required consent state. We reviewed Cookiebot, GTM, and consent signals, restructured the setup, and validated consent-aware tracking.

Send us your GA4 setup, your goals, or just a hunch that something’s not tracking right. We’ll come back with a fixed estimate and a documented plan — usually within one business day.
FAQ
A standard GA4 audit is typically returned within 2–3 business days of getting access to your property and site. A full implementation — custom events, ecommerce tracking, and Consent Mode — usually takes 1–2 weeks depending on how many event types and funnels are involved. Larger multisite or cross-domain projects are scoped individually, typically 2–4 weeks. We’ll give you a specific timeline in writing before any work starts.
Both — we recommend whichever fits your existing stack. If you’re already running GTM for ads or other tags, we build on top of that rather than adding a second, independent tracking install (which causes double-counting). If you have no existing setup, we typically recommend GTM for its flexibility with future tags, but a simple site with no other marketing tags can be perfectly well served by a direct gtag install. We’ll walk you through the trade-off during the scoping call, not just default to one silently.
It’s included in any implementation project, and available as a standalone engagement if you already have GA4 running but never wired up consent. We configure default-denied consent states, region-specific CCPA handling, Global Privacy Control (GPC) detection, and connect your existing cookie banner (Cookiebot, OneTrust, CookieYes, Complianz, or a custom one) so consent signals actually reach GA4 — not just sit in a banner that looks compliant but doesn’t talk to your tags.
Yes. We build out the complete funnel — product views, add-to-cart, cart views, checkout starts, and purchases — using each platform’s own events and hooks rather than guessing at timing with generic click listeners. That means accurate item IDs, prices, and quantities on every event, and no double-firing between your plugin’s own tracking (if any) and what we add.
Every project ends with a written documentation file listing every event we implemented — what triggers it, what parameters it carries, and where the code lives. This isn’t optional paperwork; it’s what lets your team (or your next developer, or us on a future engagement) know what’s tracked without reverse-engineering the site. A GA4 setup with no documentation is a liability the moment the person who built it moves on.
We verify every single event live — in GA4 DebugView and by inspecting the actual network requests — before calling anything done. This catches the failure mode we see constantly in audits: tracking that looks correctly configured in the code but never actually fires, because of a timing bug, a consent-gating issue, or a selector that doesn’t match the real markup. Configuration without verification is guesswork; we don’t ship guesswork.
Most sites we audit have GA4 “installed” in the sense that it’s collecting page views, but are missing a meaningful share of the events the business actually thinks it has — broken ecommerce events, forms that don’t fire on AJAX submission, duplicate installs counting page views twice, or consent gating that silently blocks tracking for a large share of visitors. An audit tells you exactly what’s live, what’s broken, and what’s missing, with no changes made until you approve a plan.
Yes — most of our GA4 work is scoped and delivered without touching your site’s template or feature code at all. Tracking code lives in its own isolated files, separate from your theme or plugin logic, specifically so it doesn’t create merge conflicts or step on work your existing team is doing elsewhere.
Yes — this is a significant part of our work. We deliver under your agency’s brand, with documentation and reporting formatted for you to hand directly to your client, and we’re comfortable working entirely behind the scenes on calls, in Slack, or in your project management tool of choice.
Both, if you want it. Reporting gets you accurate dashboards; Insights goes further — a monthly read on where your funnel is leaking and which segments are worth doubling down on, handed to you as a short list of what to act on next rather than a dashboard you have to interpret yourself.
