Because many of the apps available on SiteApps could offer a better user experience if the tag is loaded in the beginning of the page, we recommend to implement it in the <HEAD> section of your HTML code, right before closing the </HEAD> tag. Some apps may use information from the webpage (such as the Head Title or Meta Description), so make sure the SiteApps tag is placed after these.
But the tag can be implemented anywhere on the site, and some may prefer to install it at the end of the HTML code, right before the </BODY> tag.
SiteApps can be used as a tag management system. If you will be using testing platforms or other applications that will dynamically update your web site - we strongly recommend that you use the synchronous version of the tag.
Important note: Changing from asynchronous to synchronous tags requires a site code change. If in doubt, do install the synchronous version (that supports testing platforms).
We constantly work to optimize the response time for the SiteApps tag.
