The 'global data'-feature is a great way to manage the most basic parts of your content across all your pages and channels (including desktop site, Mobile and Facebook). These basic content parts are those bits of content that are being used in many different locations and modules across your site - e.g. phone number, address, business name, email address and the likes.
With global data, you only need to enter the basic information once. The information will then be automatically fed into all the relevant modules on your site. This feature makes it easy to update your site - for example if your company moves to another location. Simply fill in the new address on the global data page and the information will be updated all over - with one click!
In other words, when linking to global data, you don´t have to open multiple modules to apply the same change. Just edit the value for each tag (phone number, street name etc.) in the global data page under: My account/Global data.
Some modules are by default set to sync with the data you have entered in your global data settings. But you can also call upon your global data elsewhere on your site by typing the global data 'tags'.
