Container Tag – Importance in Online Marketing

Container Tag s can be used in online marketing for many different marketing activities.

Common uses:

  • the retargeting of website visitors
  • in affiliate marketing
  • for A/B testing of websites
  • website analysis


Container Tag s only need to be integrated into a website once and can then be automatically controlled centrally.

The Tag Manager can be used at any time to check which tag is currently being displayed on the website. A significant advantage of the Container Tags is the time saved in the maintenance of websites. Especially with very complex and extensive websites, the manual maintenance of the tags is associated with a high effort.
