Many websites use tag management systems to keep all analytics and marketing scripts under control. Tag management systems provide quite an easy way of doing that. However, most of the time, tag managers are loaded client-side – meaning that all the scripts and tags that are installed via these systems are loaded directly in the users’ browser. This means that client-side tagging has two distinct downsides:
- Negative impact on website performance: as the tag management system loads many scripts and executes many different tags it can have a negative impact on the website’s performance (loading speed, response time, etc.)
- Privacy Concerns: Since all the scripts are loaded directly in users’ browsers, it can pose a risk that these third-party vendors can access information, that should have not been exposed to them (for instance, the IP address).
The benefits of Server-Side Tagging
Secondly, reducing the number of loaded scripts drastically improves the overall security of the website. With Server-side tagging, you are placing third-party tags into a safe server environment, where these tags can work only with the data that you provide them.
This provides you with full control over what information is collected by these third parties. You control what is anonymized, pseudonymized, or what is stripped out completely (e.g. you can choose to protect IP addresses of your users by anonymizing them, or stripping them completely, so they never reach third-party servers in the first place, which was one of the issues in the recent Austrian Data Protection Authority ruling).
What are the next steps?
Obviously, Server-side tagging is only one piece of the puzzle if you really want to be in control of data collection on your website. Server-side tagging should go hand in hand with proper implementation of the Consent Management Platform (CMP), which ideally integrates Google’s Consent mode.
