Omniconvert Cookies Reference

When does Explore NOT set cookies?

There are a few situations where Explore sets no cookies at all:

  • GDPR consent not given - if your visitors are in the EU and haven't given GDPR consent, Explore doesn't set any cookies.

  • Older browsers - this also happens on Internet Explorer 10 and below.

  • Tracking code disabled - if you disable the Explore code from the platform, everything is disabled, including experiments and cookie setting.
    ​

When are Explore cookies set?

Aside from 3 core cookies (one of which is automatically deleted), cookies are only added when certain conditions are met:

Condition: Viewed a page

Happens whenever a visitor loads any page containing the Explore tracking code.

Condition: Bucketed in an experiment

Whenever a visitor passes the rules configured for an experiment - Device Type, Audience Pages, Frequency, Traffic Allocation, segmentation, and more - they're bucketed into that experiment, and this contributes to the data collected for their experience.

Condition: Experiment has frequency throttling

Some experiments are set to show only once per day, week, month, session, or lifetime - this is called Frequency Throttling. This is treated as a special case that can improve perceived performance for your visitors.

When do Explore cookies expire?

Expiration depends on when a cookie was last updated - each entry in the table below shows how long the cookie remains active after its last write, not from when it was first set.

Note

A cookie's expiration resets every time it updates.
