Imagine your website is a backpack. In traditional Google Tag Manager (GTM), every tracking tag (like Facebook or Google Ads) is a heavy book you put inside that backpack. The more books you add, the slower the person (your visitor) walks.

A Server Container acts like a separate delivery truck. Instead of putting all the heavy books in the backpack, the visitor just carries one small note. That note is sent to your private server, and the server does all the heavy lifting of sending information to Google or Facebook.

This makes your website load significantly faster. By using tools like Seers AI within a server container, you can also strip out sensitive personal information before it ever leaves your control, making your tracking both faster and more secure.
