Imagine you are the captain of a ship and a storm is approaching. You have two options – rely on old navigation that occasionally drops out, or invest in a reliable system that will guide you safely through even the worst weather. For e-commerce, the storm is the fourth quarter and server-side tracking is your modern navigation, making sure you don’t lose a single crown of your marketing investments.
While most companies focus on preparing stock and marketing campaigns for Black Friday and Christmas, they often forget one crucial detail: reliable measurement of results. Yet it is precisely during the fourth quarter, when the success of the whole year is decided, that accurate tracking is absolutely essential.
Summary for Those Who Don’t Have Time to Read the Whole Article
- Server-side tracking can capture up to 30% more conversions than the classic solution, which during Black Friday and Christmas can be a difference of millions of crowns.
- It can significantly speed up the loading of your website exactly when you need it most (at high traffic).
- It ensures accurate attribution even when customers use ad blockers or Safari with privacy protection.
- It optimises advertising spend in real time thanks to complete data for the Google and Meta algorithms.
- Implementation takes a certain amount of time, so it is ideal to start as early as possible before the season.
Do you need help implementing server-side tracking before the season? We will help you set up reliable tracking before Black Friday. We will find out how much data you are currently losing and prepare a solution tailored to your e-shop.
What Is Server-Side Tracking?
Server-side tracking is a modern way of collecting data about the behaviour of your website’s visitors. Instead of the data being sent directly from the user’s browser to Google systems or the Facebook Pixel, it first travels to your server, where you process it and only then send it on.
When a visitor adds a product to the basket, the data about this action is first sent to your server. It processes it, enriches it with further information (for example the order value from your system) and then passes it on to the advertising platforms. All of this happens within milliseconds, so the user notices nothing.
However, modern browsers and extensions such as ad blockers block classic tracking transmissions. Server-side tracking gets around this problem, because the communication takes place between servers, not between the browser and a third party.
Why Does Q4 in Particular Require the Most Reliable Tracking?
The fourth quarter is not just another part of the year. It is the period when most e-shops generate a substantial part of their annual turnover. Every lost conversion, every badly measured purchase means worse campaign optimisation and a higher cost of acquiring a customer.
During Black Friday your e-shop may see many times higher traffic. Google Ads and Facebook are running at full speed, budgets are being increased and every crown must work efficiently. But it is precisely at this moment that classic tracking begins to fail.
Imagine the following situation: your website is dealing with triple the traffic, customers switch between mobile and computer, use different browsers, and on top of that half of them may have an ad blocker turned on. In this situation classic tracking captures perhaps 60% of real conversions. Server-side tracking ensures that even though you have significantly more visitors a day during Black Friday, you don’t lose valuable data about their behaviour. The Google and Facebook algorithms then receive complete information and can better optimise your campaigns in real time.
Three Key Advantages for Your Campaigns
- More accurate measurement – When a customer starts a purchase on their mobile at work and completes it in the evening on their computer at home, classic tracking often assigns the conversion wrongly or loses it altogether. Server-side tracking, using advanced identifiers, correctly connects the whole customer journey across devices.
- Higher ROAS – Server-side tracking gives the Google and Meta algorithms complete conversion data, including conversions that classic tracking would not capture. Your campaigns learn faster, target better and bring a higher return on investment.
- A faster website – When you have several times more visitors during Black Friday, every millisecond counts. Server-side tracking moves most of the tracking load to the server. Google also uses website speed as a factor in determining the cost per click (a faster website means cheaper advertising).
When to Start Implementing?
Implementing server-side tracking in the middle of the Christmas season is like changing the engine while driving. It can be done, but it is certainly not ideal.
September is the perfect time to start planning. In October the implementation itself takes place, and in November you have room for testing and optimisation. When Black Friday arrives, your server-side tracking is already running like clockwork and you can focus on campaigns instead of dealing with technical problems.
The whole process usually takes several weeks depending on the complexity of your e-shop. We will be glad to take care of it.
Conclusion
Server-side tracking during the fourth quarter is not a luxury, it is a necessity for every e-shop that wants to maximise its potential during the most important period of the year. The difference between incomplete and complete conversion capture can mean millions of crowns in revenue during Black Friday and Christmas.
If you want to be ready for the next season, start planning now. Your competitors may have already started, and every day you work with incomplete data means lost opportunities and higher marketing costs.
Server-side tracking is an investment that pays off during the very first Black Friday weekend. And then it will bring you benefits all year round.
Frequently Asked Questions
How long does it take to implement server-side tracking before the season?
A standard implementation takes several weeks depending on the complexity of the e-shop and the number of platforms. We recommend starting at the latest 6 weeks before Black Friday for testing and optimisation.
Is server-side tracking more expensive than classic tracking?
Monthly costs depend on the volume of data and the size of the project. Small projects have low costs, medium and large projects with high traffic understandably higher ones. However, the investment can pay off thanks to better campaign optimisation and a higher ROAS.
Does server-side tracking work with all advertising platforms?
Yes, the main platforms have official support: Google Ads, Facebook/Instagram, Pinterest, TikTok, Microsoft Ads and LinkedIn. Other platforms may also have server-side tracking, but in the form of a custom solution. You can also combine server-side and client-side tracking as needed.
