Understanding how users interact with websites or applications is crucial in today’s data-driven world. This is where web analytics, particularly server side tagging, comes into play. Tagging involves small bits of code that record users’ activities. The key to obtaining the best results from these tags lies in deciding whether to implement them on the server side or client side.

This choice is critical because the method of tags implementation directly affects the quality and reliability of your data.

The Importance of Choosing the Right Data Tracking Method

The method you choose for tag implementation—whether server side vs client side—directly impacts the quality and reliability of your data.

Here’s why choosing the right approach is important:

1. Improved Data Accuracy: Ensure consistency and completeness of collected data, regardless of user device or browser limitations.
2. Enhanced Privacy Compliance: Address growing data privacy concerns by maintaining control over collected information.
3. Boosted Website Performance: Reduce the potential for tag bloat and keep your website loading quickly for a better user experience.

Understanding the differences between client side vs server side tagging empowers you to make the best choice for your needs.

What is Client-Side Tagging and Why is it No Longer Enough?

Client-side tagging is an older technique that requires placing tracking codes or tags in the client’s browser. When a visitor interacts with a site, tags trigger and immediately pass data to third parties for evaluation or marketing purposes.

However, client-side tagging is not without its drawbacks. Due to increasing restrictions by browsers on cookies, ad pop-ups, and various policies like GDPR, client-side tracking can lead to data loss or inaccuracies. Additionally, running multiple tags simultaneously may negatively impact web performance.

Pros and Cons of Client-Side Tracking

Pros:

• Simplicity in implementation.
• Direct integration with many marketing and analytics tools.
• Real-time data collection.

Cons:

• Vulnerable to ad blockers and browser restrictions.
• Potentially slows down website performance.
• Limited control over data security and privacy.
• Inaccuracy in data due to client-side failures or limitations.

What is Server-Side Tagging?

Server-side tagging is an advanced approach where the tracking codes are executed on the server rather than the user’s browser. In this method, the server collects and processes data before sending it to third-party services. This approach offers greater control over data collection, improved security, and better compliance with privacy regulations.

Pros and Cons of Server-Side Tracking

Pros:

• Improved data accuracy and reliability.
• Enhanced control over data security and privacy.
• Reduced impact of ad blockers and browser restrictions.
• Better website performance due to offloading of tracking tasks to the server.

Cons:

• More complex to implement and manage.
• Higher initial setup and maintenance costs.
• Requires more technical expertise.

Key Differences Between Client-Side and Server-Side Tagging

The primary difference between client-side and server-side tagging lies in where the data processing occurs. In client-side tagging, the user’s browser handles data collection, while in server-side tagging, the server processes data before sending it to third-party services.

Feature	Client-Side Tagging	Server-Side Tagging
Implementation	Code placed directly on website/app	Code executes on server-side
Data Collection	Prone to inconsistencies	Ensures consistent data
Privacy Control	Limited control	Offers greater control
Website Performance	Can slow down website loading	Improves website loading speed
Complexity	Easier to implement	Requires more technical expertise
Cost	Often free solutions available	Might incur additional fees
