80% of traditional tracking implementations are losing accuracy due to cookie blocking and the growing concern for user privacy.

But there’s a solution that not only improves the quality of the information you collect but also prepares you for a future more focused on user privacy: Server-Side Tracking.  

Can you imagine having complete control over the data, reducing reliance on browsers, and at the same time improving the speed of a webpage?  

It’s not science fiction; it’s reality. In this article, we will explain what Server-Side Tracking is, how it works, and most importantly, the benefits it can bring to your digital strategy.  

Spoiler: it could forever transform how you view analytics.

Server-Side Tracking: What is it and what is it for?

In the realm of analytics and digital marketing, the term “server-side” refers to a technique in which data logic and processing occur on the server rather than the user’s browser (client). Unlike the client-side approach, where scripts run directly in the user’s browser, server processing offers greater control over the data.

Server-side tracking involves sending data from your own server directly to analytics and marketing platforms, such as Google Analytics and Facebook Pixel, among others.

This method is becoming increasingly popular in response to the challenges posed by privacy restrictions and ad blockers, which affect traditional cookie-based third-party tracking methods.

Benefits of implementing Server-Side Tracking.

Server-side tracking offers multiple benefits, making it especially valuable in today’s digital analytics landscape, where user privacy and data accuracy are paramount.

1. Improved privacy and data security.

  • Protection of personal data: By processing data on the server, the amount of personally identifiable information (PII) stored in the user’s browser is reduced, lowering the risk of data being intercepted or tampered with by malicious client-side scripts.
  • Regulatory compliance: Server-side tracking facilitates adherence to privacy regulations such as the GDPR in Europe or the CCPA in California, as it allows for stricter control over the data collected and how it is shared. For example, it is possible to ensure that only the strictly necessary and anonymised data is sent to third-party platforms.

2. Greater control over data.

  • Customisation of data collection: You can define exactly what data is collected, how it is processed, and when it is sent to other platforms. This is highly useful in complex environments where data from different sources need to be integrated and normalised before analysis.
  • Integration with internal systems: Server-side tracking enables smoother integration with other internal systems, such as customer databases and CRM. This is crucial for creating a single source of truth that can feed both analysis and personalised marketing actions.

3. Reduced client-side load.

  • Improved website performance: By shifting data processing to the server, the load on the user’s browser is lightened, which can result in faster loading times and a better user experience. These factors are crucial for maintaining user engagement and reducing bounce rates.
  • Resource optimisation: Fewer scripts and less client-side load also mean that devices with lower processing capacity, such as mobile phones, can browse the website more efficiently, improving accessibility and user experience across different devices.

4. Bypass ad blockers.

  • Evasion of ad blockers: Ad blockers are less effective against server-side tracking. By using your own server, cookies are considered first-party, which extends their lifespan and reduces the likelihood of them being blocked. This allows for more accurate and complete data on user activity, even in environments where ad blockers are used.
  • Consistency in tracking: Maintaining the integrity of tracking data is crucial for data-driven decision making. Server-side tracking offers a more consistent and complete view of user behaviour, helping to optimise marketing and analytics strategies.

5. Greater reliability in data collection.

  • Reduction of discrepancies: By handling tracking from the server, discrepancies caused by client-side script loading issues or incorrect browser settings are reduced.
  • Data quality control: It allows the implementation of quality control procedures before the data is sent to other platforms, ensuring that only accurate and validated data are analysed and stored.

 

To reap these benefits, it’s essential to carry out a careful implementation that considers the existing technological infrastructure, user privacy, and the specific needs of the business. This involves not only choosing the right tools but also training staff in effective and ethical data management and analysis practices.

In summary, server-side tracking offers significant advantages in terms of data accuracy, website performance, regulatory compliance, and user experience, making it a strategic investment for businesses looking to enhance their analytical capabilities and marketing effectiveness in an increasingly regulated and competitive digital environment.

How to implement Server-Side Tracking?

Successfully implementing server-side tracking involves a series of technical steps and strategic decisions to ensure that the system not only works correctly but also complies with legal requirements and performance expectations. Here’s a step-by-step guide:

Step 1: Needs Assessment and Planning.

1.1 Definition of Objectives:

  • Determine what information needs to be collected and which analytics or marketing platforms will need the data.
  • Identify specific data compliance and privacy requirements.

1.2 Choice of Technology:

  • Select a suitable tag server, such as Google Tag Manager Server-Side.
  • Consider infrastructure needs (servers, bandwidth, security, etc.).

Step 2: Setting up the Server Environment.

2.1 Tag Server Setup:

  • Install and configure the tag server software in a secure server environment.
  • Adjust data collection so that client-side events are sent to the server via HTTP requests.

2.2 Security and Privacy:

  • Implement security measures, such as HTTPS, to protect data transmission.
  • Ensure that server-side data processing complies with applicable privacy laws (such as GDPR).

Step 3: Data Integration and Collection.

3.1 Client-Side Event Collection:

  • Modify the website or app so that event data (clicks, page views, interactions) is sent to the server instead of directly to third-party platforms.
  • Maintain hybrid tagging (client-side and server-side) when necessary for tools that do not yet support server-side.
  • Use APIs or POST forms to transfer data securely from the client to the server.

3.2 Server-Side Processing:

  • Implement scripts or programs on the server to receive, process, and validate the data before sending it to other platforms.
  • Enrich data with additional information stored on the server, if necessary.

Step 4: Sending Data to External Platforms.

4.1 Third-Party API Setup:

  • Configure API connections with analytics and marketing platforms to send data from the server.
  • Ensure that the data sent is necessary and in the proper format for each platform.

4.2 Testing and Validation:

  • Conduct thorough testing to ensure that the data is collected and transmitted correctly.
  • Validate data quality and tracking functionality.

Step 5: Monitoring and Optimisation.

5.1 Continuous Monitoring:

  • Set up monitoring systems to continuously verify the integrity and performance of the tracking system.
  • Use log analysis and server monitoring tools to detect and resolve issues quickly.

5.2 Optimisation and Updates:

  • Regularly analyse the effectiveness of the tracking system to identify areas for improvement.
  • Update configurations and scripts as necessary to adapt to changes in target platforms or privacy regulations.

The future of tracking lies in the server.

Implementing server-side tracking is a technical process that requires careful planning and precise execution. In addition to technical skills, an advanced understanding of digital analytics, data privacy, and systems architecture is essential.

A collaborative approach involving IT, marketing, and legal compliance teams can ensure that the implementation is successful and sustainable in the long term.
