__utmt_t15 Cookie

What does the __utmt_t15 cookie do?

__utmt_t15 is a cookie used by Google Analytics to track visitor behavior on a website, specifically the time it takes for pages to load and measure the effectiveness of site performance.

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.
