Tagging Reference - Legacy Libraries


We strongly recommend that all users upgrade their tracking to a version of the Universal Analytics tracking code: analytics.js JavaScript library, the latest Mobile SDK for Android or iOS, and the Measurement Protocol. By updating your tracking code, you'll get access to new features and product updates.


urchin.js users should upgrade to the analytics.js library. You can refer to the analytics.js developer documentation for implementation details.

WAP / server-side snippets and other legacy libraries

If you use WAP (Web Application Protocol) / server-side snippets, send data to properties prefixed with YT / MO, or any other legacy libraries (including Flash or Flex, Silverlight), you can update your tracking implementation to use the Measurement Protocol. Refer to the Measurement Protocol developer documentation for implementation details.
