Why us?

Why choose us for server-side tracking?

The founder of AdOps Digital, Zoltán Csentes, has worked in online marketing for more than 20 years; one of his main specialisms is web analytics and AdOps – which is no coincidence, given our agency's name.

Alongside our own consent banner and custom dashboards, we are also at home in server-side tracking.

The problem

Why is traditional (client-side) tracking not enough?

Most UNAS, Shoprenter, Shopify or WooCommerce online stores use browser-side tracking. Because of iOS restrictions, ad blockers and short cookie lifetimes, advertising systems don't receive enough data to optimise. The problem is not your creative or your ad – it is data quality. If you spend at least HUF 300,000–500,000 a month on Google or Meta ads, this service is practically a must.

  • Ad blockers block tracking

    Not only ads but tracking tags too: GA4 doesn't receive the events, the Meta Pixel doesn't record purchases, and the Google Ads conversion doesn't fire.

  • iOS and Safari restrictions

    Third-party cookies are blocked, the lifetime of first-party cookies may also be shortened, and the browser actively reduces tracking options.

  • 1–7-day cookie lifetime

    If someone clicks an ad but only buys 8 days later, the conversion often doesn't make it back to the advertising platform.

  • Attribution errors

    The campaign shows fewer conversions, “direct” traffic grows, channel evaluation is distorted – and budget allocation goes wrong.

  • Campaigns stuck in the learning phase

    If the Meta and Google algorithms receive few or delayed conversion signals, the campaign stays in the learning phase longer and runs at a higher CPA.

  • Different figures in different systems

    GA4 shows one thing, Meta another and the backend yet another – because of a blocked pixel, an expired cookie, incorrect consent settings or cross-device tracking errors.

  • Too much “direct” and “unassigned” traffic

    If attribution doesn't work, the campaign is undervalued – so you can easily switch off a campaign that is actually profitable.

  • Weaker optimisation

    Without stable conversion signals, CPA is higher, ROAS is lower, performance fluctuates and scaling is difficult.

What you get

The solution: server-side tracking

The essence of server-side tracking (sGTM) is that we place a server between the website and the platforms, and move data collection from the browser to a controlled server environment.

  • More measured conversions

    We recover some of the events lost to ad blockers and iOS.

  • Longer cookie lifetime

    Instead of short-lived cookies, the systems work with longer-lived first-party cookies.

  • More stable attribution

    There will be less “direct” and “unassigned” traffic in GA4, because the system can assign visitors to a channel.

  • Better Meta Event Match Quality

    With the Facebook Conversions API, Meta sees much more and more accurate data.

  • Better Enhanced Conversions data

    Google Ads also receives customer data server-side, so it knows exactly whom the campaign brought in.

  • Stronger remarketing audiences

    Visitors who were previously invisible to the system also make it onto your lists.

  • Faster website

    The browser runs fewer scripts, which improves page load speed.

  • Less bot traffic

    We can exclude obvious bot traffic from tracking, so the platforms work with cleaner data.

  • You can see ad blocker users

    You will know exactly what percentage of your visitors use an ad blocker.

Process

What does the setup look like?

We provide the entire infrastructure for a monthly fee. We always start with an audit to see whether everything is in place for the job. We will need access to GA4 and GTM, Google Ads and Meta, your domain and DNS, and your online store or website admin.

Let's get started
  1. Step 1

    New tracking environment

    We create brand-new GTM and sGTM containers that you only need to place on your website.

  2. Step 2

    First-party domain

    We provide the intermediary server that forwards data to the platforms from your own domain.

  3. Step 3

    Facebook Conversions API

    We set up not only the Meta Pixel but the Conversions API (CAPI) as well.

  4. Step 4

    GA4 server-side integration

    From now on, data arrives in your Google Analytics account server-side.

  5. Step 5

    Google Ads setup

    We set up server-side tracking of Google Ads conversions and the Enhanced Conversions feature.

  6. Ongoing

    Support

    We provide continuous, high-quality support in managing your tracking.

We worked with the AdOps agency on configuring a GA4 account, setting up a GTM account and setting up conversion tracking in our ad account. Zoltan paid attention to every detail […] At the end of the project we also received full documentation + a short training session on Google Ads. I wholeheartedly recommend them to anyone who wants fast and accurate work!

FAQ

Frequently asked questions about server-side tracking

Can't find the answer? Email us at hello@ad-ops.hu or call us on +36 70 784 6000.

What is server-side tracking?

Server-side tracking (server-side measurement, sGTM) is a measurement solution in which data is not collected directly from the browser but through a controlled server environment. It enables more accurate conversion tracking, first-party cookies, better attribution and more stable Meta and Google Ads optimisation, and it reduces the impact of ad blockers.

How does it differ from traditional (client-side) tracking?

With client-side tracking, the browser sends data directly to the platforms – ad blockers can block it, iOS can restrict it, and short cookie lifetimes can also cause problems. With server-side tracking, the data first passes through a server and runs on a first-party domain, which allows longer cookie lifetimes and more stable signal quality.

Is it only recommended for online stores?

No. Server-side tracking matters for every website that advertises on Google Ads and/or Meta. It is especially recommended if your GA4 and backend figures differ, you have a lot of “direct” or “unassigned” traffic, a significant share of iOS traffic, you run serious remarketing, or ROAS optimisation is key.

Is it compatible with UNAS and Shoprenter?

Yes. Our solution is compatible with UNAS, Shoprenter, Shopify and WooCommerce, as well as with custom-built websites. The technical integration is always bespoke, but it does not require changing your platform.

Does it slow down the website?

Quite the opposite. Server-side tracking reduces the number of scripts running in the browser, which can lead to faster page loads and a better user experience, and can also improve the conversion rate.

How much of an increase in conversions can I expect?

The exact result depends on your current level of data loss, the share of iOS traffic, your campaign structure and the share of remarketing. The goal is to make more conversions measurable, lower the CPA and improve the ROAS.

Do I need a developer?

In most cases, no separate development team is needed. We assume that basic e-commerce tracking is already in place, but with custom-built stores we often find incomplete data – in those cases development work will also be required.

How long does the setup take?

We always start with an audit to see whether everything is in place to do the job. The full implementation takes 5–10 working days, followed by 1–2 weeks of fine-tuning and checks.

How much does server-side tracking cost?

The service is charged as a monthly fee. The fee depends on your store's traffic, the number of advertising platforms you use and the number of tracking tags to run – request a quote and we will calculate it.

What happens if I don't switch to server-side tracking?

In the short term, things may keep working for a while. In the long term, however, you have to expect growing data loss, deteriorating optimisation, a competitive disadvantage and higher advertising costs, because the advertising platforms' algorithms increasingly favour first-party and server-side data.
