Your algorithms are only as smart as the data you feed them

Most agencies lose 20-40% of conversion data to ad blockers, browser restrictions, and misconfigured tracking. Your ad platforms optimize on what's left. We fix that.

The Problem

Shit in, shit out.

Your algorithms are only as good as the signals they receive. When a third of your conversions are invisible, they optimize on a fraction of reality.

Ad blockers strip your data

30-40% of events never reach your ad platforms. Your algorithms optimize on a fraction of reality.

Cookies expire in days

Safari limits cookies to 1-7 days. Your attribution breaks. Revenue gets credited to "direct."

Numbers never match

GA4 says one thing, Meta says another. Client meetings start with excuses instead of results.

Every euro of ad spend is under more pressure than ever. CPA is rising, algorithms are getting hungrier for data, and your tracking setup hasn't kept up.

Performance Max, AI Max, Advantage+ — they treat winners as losers and keep burning budget on what doesn't work. Not because the campaigns are wrong, but because the data feeding them is incomplete.

You're not overspending on ads. You're undercounting conversions. And from the inside, both look exactly the same.

The agencies that win aren't the ones with bigger budgets. They're the ones whose data foundation gives the algorithm the full picture.

The deeper problem

Your platforms say you're winning.
Your revenue disagrees.

It's not just missing data. The data you do have is misleading. Platforms claim credit for email-driven purchases, returning customers, and direct traffic. The algorithm doesn't distinguish. It optimizes on a version of reality that never existed.

Our infrastructure

Three layers between your visitor
and the full picture

No browser dependency. No adblocker gaps. Data captured at the network level, routed through your own server, and stored in your own warehouse. Complete, accurate, and yours.

01

Edge attribution

A lightweight script runs at DNS level, before your site loads. It sets a first-party visitor ID and captures the original click source. Not blockable by iOS, Safari, or adblockers. Cookie lifetime: 1 year.

Visitor ID First-click source

02

Server pipeline

Events route through your own subdomain. Server-side tagging reads cookies from request headers and sends clean, deduplicated data to every ad platform. A direct webhook from the edge layer ensures data arrives even if client-side JavaScript fails entirely.

GA4 Meta CAPI Google Ads Webhook

03

Single source of truth

All raw events land in your own data warehouse. Automated pipelines transform them into attributed sessions, funnel analysis, and conversion imports. New vs returning customers, true first-click attribution, full-journey visibility.

Your data Conversion import Lead scoring

The edge layer also sends data directly to your server and warehouse — a second path that bypasses the browser entirely. Even if everything client-side fails, your data is already there.

Who This Is For

Sound familiar?

Agencies that "have it covered"

Your tracking works. But is it compliant? Adblocker-proof? Are you getting the maximum out of it?

Teams drowning in data chaos

GA4 says one thing, Meta says another. Your CRM says something else. Nobody knows what's true.

Agencies thinking ahead

Privacy laws evolve, browsers restrict more, AI bidding needs better data. The gap is only growing.

FAQ

Frequently asked questions

What is server-side tracking and why does my agency need it?

Server-side tracking moves data collection from the browser to a server you control. Instead of relying on JavaScript tags that ad blockers strip and browsers restrict, events are sent server-to-server directly to ad platforms like Meta, Google Ads, and TikTok. This recovers 15-40% of conversion data that browser-side tracking silently loses. For agencies, this means your bidding algorithms finally optimize on the full picture — lower CPA, higher ROAS, and reporting that matches reality.

How much conversion data are we losing right now?

Most websites lose between 20-40% of conversion events to ad blockers, browser tracking prevention, and misconfigured setups. Safari's Intelligent Tracking Prevention (ITP) limits cookies to 1-7 days, breaking attribution for any customer journey longer than a week. Our free audit shows you the exact percentage for your setup — no guessing, just data.

What makes Archon Labs different from doing it in-house?

Having the tool is not the same as having it right. Agencies can set up Stape or Taggrs themselves — the tools are accessible. But is the setup actually adblocker-proof? Are UTM parameters and click IDs protected? Is consent properly configured? A basic implementation and an optimized one can differ by 20-30% in recovered data. The tool is the easy part. The configuration is where the value lives. We save agencies an average of 14 hours per project compared to handling it internally.

What is the Kyrios custom pixel?

Kyrios is our proprietary first-party tracking pixel that sends analytics data directly to BigQuery, completely bypassing GA4 and its limitations. You get unsampled data, unlimited retention (not 14 months), metric definitions that live in code rather than scattered across calculated fields, and numbers that are consistent across your entire team. It's a single source of truth — one dataset, one answer, no discrepancies.

How long does a typical implementation take?

A standard server-side tracking implementation takes 1-2 weeks depending on the complexity of your setup and the number of ad platforms involved. This includes the full sGTM configuration, consent flow integration, conversion API setup, and a two-week monitoring period to verify everything is firing correctly. No learning curve on your side — we handle the entire technical implementation.

Do you work white-label for agencies?

Yes. We work as your invisible data team or as a named external specialist — your call. In white-label mode, your clients never know we exist. We handle the data infrastructure behind the scenes while your team takes credit for the results. Either way, the outcome is the same: complete, accurate data and campaigns that perform better.

Is server-side tracking compliant with GDPR?

Yes — and it actually gives you more control, not less. With server-side tracking, you decide exactly what data leaves your server and where it goes. No rogue third-party scripts firing before consent. No data leaking to vendors you didn't approve. Combined with a properly configured consent management platform, server-side tracking is the most privacy-compliant way to run performance marketing in 2026.

Is my agency too small for this?

Almost never. Agencies with 3-20 people often have more to gain from proper data infrastructure than larger companies. At that size you're still nimble enough to actually act on the insights. The same cloud tools and infrastructure that power enterprise analytics are available today at a fraction of the cost. You don't need a six-figure budget or a dedicated data team. You need a specialist.
