How long is an Optimize variant cookie attached to a user?

Hello Optimize Community,

 

From what I understand, when a user lands on a variant for an Optimize test, they are cookied to make sure that if they return to that page they won't see a different variant. For example:

 

- User lands on Variant A for Test 1, Optimize cookies that user for Variant A

- Same user returns to that same page, cannot see Variant B for Test 1 due to Optimize cookie

 

How long is this cookie attached to a user? Or if my description of how Optimize identifies users is incorrect, please let me know!

 

Cheers,

Hi,

 

Yes, users will see the same version for the time of the experiment:

"Depends on the length of the experiment but typically 90 days."

Hope this helps.
