Big brands are increasingly measuring via their own servers. You hear a lot about it, but it sounds technical and expensive. That is why many business owners assume it is not for them.
That is only half true. Server-side tracking is not necessary for everyone. But for an SME that advertises consistently, it can certainly pay off. In this article you will read what it is, what it costs and when it is worth the effort.
What is server-side tracking?
With standard tracking, code runs in your visitor’s browser. That code sends data directly to parties such as Google Analytics, Google Ads and Meta. Your visitor therefore loads several scripts from different companies.
Server-side tracking works differently. The browser first sends the data to a server that you manage. That server processes the data and then forwards it to Google, Meta or another advertising partner.
You can compare it to a mail room. Without a mail room, everyone delivers their own letter to ten different departments. With a mail room, everything arrives in one place. You decide what goes out afterwards.
Why measuring is getting harder
Your advertising is only as good as your measurement. If you miss conversions, Google and Meta get an incomplete picture. Their bidding systems then learn from too little data. That costs you money.
Measurement goes wrong for several reasons:
- Ad blockers: these block requests to known tracking domains. As a result, some of your visitors never appear in your figures.
- Browser restrictions: Safari and Firefox limit how long cookies are kept. A customer who returns after two weeks is then counted as a new visitor.
- Consent: not everyone accepts cookies. That is their right, and you need to take it into account.
- Slow websites: many scripts in the browser make your site heavier. You notice this in the loading time.
Server-side tracking solves some of these problems. Not all of them, and it is important to know that. We will come back to this later.
The benefits for a smaller business
The biggest benefit is more reliable data. If the server runs on your own domain, browsers and ad blockers more often treat the traffic as part of your own site. As a result, less is lost.
You also gain more control over what you share. On the server, you can filter data before it goes to an advertising partner. That way you only pass on what is needed. Think of an email address that you encrypt first, or a field that you leave out entirely.
A third benefit is speed. Fewer scripts run in the browser, because part of the work moves to the server. Your site usually becomes lighter as a result. That helps your visitors and your search visibility too.
Finally, you gain room to enrich your data. For example, you can send the revenue or margin of an order. That way your campaigns learn from what actually makes money, not just from the number of orders.
What it costs and what you need
Server-side tracking is not free. You need a few things:
- A server or hosting service, such as Google Cloud or a specialist provider.
- Your own subdomain, for example an address that ends in your own domain name.
- A server container in Google Tag Manager, the tool you use to manage tags.
- Someone to set everything up properly, test it and maintain it.
For a smaller business, hosting often costs tens of euros per month. With heavy traffic, that can rise. The biggest cost is usually not the server, but the time it takes to set everything up properly.
Bear in mind that maintenance is an ongoing need. A server that is not kept up to date can go down. You then suddenly measure nothing at all. So make sure someone keeps an eye on your measurement.
When it pays off
A rule of thumb: server-side tracking starts to become interesting when you spend a few thousand euros or more on advertising each month. Better measurement then often pays for itself quickly. Your bidding strategy gets more data, and you have a clearer view of which campaigns work.
It pays off even more in these situations:
- You sell online and every missed conversion counts.
- Many of your visitors come via Safari or use an ad blocker.
- Your customers take a long time to decide and visit several times.
- You want to feed offline results back, such as a closed deal in your CRM.
- Your site is slow because of many marketing scripts.
A common scenario: a garden furniture webshop spends a considerable amount on Google Ads and Meta every month. Google Ads shows fewer sales than the ordering system. The gap is large and varies from week to week. Because Google sees fewer conversions, the system builds its bids on incomplete information. After the switch to server-side tracking, the figures move closer together. The campaigns can learn from real results again. The owner can steer by what was actually sold, not by what happened to be measured.
When you are better off doing something else first
Server-side tracking is not a fix for a messy foundation. If your standard measurement is not right, a server will only give you a more expensive mess.
So hold off in these cases:
- You spend little on advertising. The gain is then small compared with the cost.
- You do not yet measure clear conversions, such as purchases or enquiries.
- Your cookie banner and consent setup are not in order.
- Nobody can manage the technology in the long term.
Think about privacy too. Server-side tracking is not a way to get around consent. If a visitor has not given consent, you may not simply pass on their data. The GDPR still applies. What it mainly gives you is more control to do things properly.
How to approach it step by step
Do you want to try it? Then do not start with the technology, but with the question of what you want to measure.
- List your most important goals, such as purchases, quote requests or phone calls.
- Check whether your current measurement is accurate. For example, compare your advertising figures with your own ordering system.
- Make sure your consent banner works properly and that the visitor’s choice is passed on to your tags.
- Set up a server container and your own subdomain, and test thoroughly.
- Move the most important tags first, for example Google Ads and Meta. Then expand from there.
- Keep a close eye on measurement during the first few weeks and compare the figures with those from before.
So build it up step by step. That prevents you from going a while without measuring anything and not realising it.
Frequently asked questions
Is server-side tracking mandatory?
No. It is a choice, not an obligation. Standard tracking still works. Server-side tracking is mainly a way to make your measurement more reliable.
Will I measure all my visitors this way?
No. You will measure more, but never everything. Visitors who do not give consent remain out of view. You need to take that into account in your reporting as well.
Can I set it up myself?
You can if you have experience with Google Tag Manager and domain settings. A mistake in the setup can lead to missed or duplicate measurements. Many businesses therefore have a specialist do it.
