__utmb Cookie

What does the __utmb cookie do?

__utmb stores the time of visit to distinguish between new sessions and visits. The cookie is set when the GA.js JavaScript library loads, and it updates with each data transmission to Google Analytics.

Why this cookie matters

This cookie is commonly used by google-analytics for analytics purposes – such as tracking usage behaviour, optimising experience, or enabling marketing functionality.

Because it's categorised as analytics, many jurisdictions require that users give explicit consent before it can be activated. If blocked or denied by the visitor, related analytics features may not function properly.
