COMBINED SYNCHRONOUS AND ASYNCHRONOUS TAG DEPLOYMENT

A tag management system can implement a combined synchronous and asynchronous tag-loading scheme. In an embodiment of this scheme, a synchronous tag may be included at the top of or near the top of a content page. This synchronous tag can hide one or more page elements that are to be modified by a subsequent asynchronous personalization tag. Subsequently, the asynchronous personalization tag can update the page element and then cause the page element to be displayed. As a result, flicker between the old and new page elements can be reduced or avoided.
