About This Service

What Is First-Party Data Tracking?

Third-party cookies are disappearing and browser tracking restrictions are tightening. First-party data tracking — collecting data directly from your own customers using your own infrastructure — is the only durable solution. Adslytics designs and implements a first-party data strategy that collects, stores, and activates your customer data for advertising and analytics.

How We Deliver First-Party Data Tracking

Audit & Review

We examine your existing setup, ad accounts, and analytics to understand exactly what needs to be built or fixed.

You receive a clear, fixed-price quote with defined deliverables before any work begins. No surprises.

Build & Test

We implement and verify everything in GTM Preview mode, DebugView, or the relevant platform debugger before going live.

Deliver & Document

We launch, confirm all tracking fires correctly, and hand over full written documentation of everything built.

Why Adslytics

The Difference a Specialist Makes

Google-Certified Specialists

Every project is handled by a Google-certified tracking specialist. Not an account manager. Not a junior contractor. The person on your project is the expert.

Fixed-Price, No Surprises

You see the exact price before work starts. We scope every project fully before quoting — so you know what you are getting and what it costs, with no ongoing meter running.

Full Written Documentation

Every delivery includes documentation of what was built, what triggers each event, and how to verify it. Your team can maintain it without coming back to us.

Direct Access to Your Specialist

You communicate directly with the person doing the work. No ticketing systems, no account managers relaying messages. Direct Slack or WhatsApp contact throughout.

What Clients Say

"We had tracking spread across multiple tools with conflicting numbers and no clear source of truth. After the full tracking audit and rebuild we have clean, consistent data across GA4, Google Ads and Meta. Decision-making is so much faster now."

Jessica Howard

Head of Marketing

"Every time we made a site change something would break in our analytics. The specialist rebuilt our entire tracking layer properly, documented everything and gave us a QA checklist for future deployments. No broken tags since."

Marcus Webb

E-commerce Director

"Three months of messy data after a platform migration had left us unable to trust any of our reports. The audit identified every issue, fixes were applied within two days and we finally had reliable numbers to work with again."

Lucia Gomez

Growth Manager

FAQ

Frequently Asked Questions

Real answers to questions we hear from clients before starting a First-Party Data Tracking project.

Ask Us Anything →

First-party data is information you collect directly from your customers through your own website, app, or CRM — as opposed to data bought from third parties or tracked via third-party cookies.

Third-party cookies are being phased out, and iOS privacy changes have made third-party tracking unreliable. First-party data gives you durable, accurate measurement.

A cookie set on your own domain (yoursite.com) rather than a third-party domain. These are not blocked by Safari's ITP or most ad blockers.

Server-side tracking is the mechanism for collecting and forwarding first-party data. They go hand in hand.

Not necessarily for a first implementation. We can start with a server-side tracking foundation and add a CDP layer later.

First-party data collection must respect user consent. We integrate your data collection with your CMP to ensure compliance.

Yes — via Customer Match (Google) and Custom Audiences (Meta), you can upload hashed first-party data to target or suppress customers in your ad campaigns.

We typically set a 365-day expiry for persistent identification, refreshed on each visit.

At minimum: click IDs (GCLID, FBCLID), session ID, and conversion events. Optionally: user ID if the customer is logged in.

Yes — with proper consent flows and a clear privacy policy, first-party data collection is fully GDPR compliant.
