For Optibase to function correctly, the script must be placed inside the `` tag of your website.

#### Why the `` placement is required
* Zero Flicker: Loading the script early ensures that variants are applied before the page renders. This prevents users from seeing the original version for a split second.
* Accurate Tracking: This allows Optibase to record page views and user sessions the moment the page begins to load.
* Split Test Support: Necessary for instantaneous URL redirects during split tests.
