What is the CMP pixel?
What user data is captured with the CMP pixel?
The CMP pixel has the ID of the article currently being viewed encoded in its URL. When the pixel activates, it makes a request to Optimizely servers to track a page view which contains the user's IP address, user agent, page URL, and timestamp. The data is stored in AWS S3 and is encrypted at rest.
- __ncuid – a randomly generated ID that lasts for 365 days to track a unique visitor
- nc-previous-guid – lasts for 24 hours stores the ID of the last seen article published from CMP
The visitor IP address is not exposed through data we pull from Google Analytics. See Google Analytics' data privacy and security documentation for more on how they handle data.
What is the cookie expiry term?
CMP cookies, and cookies set by Google Analytics that CMP references, expire after 12 months from the time they are set.
Can we change the cookie expiry term?
No, you cannot change cookie expiry per instance.
