User tracking

How does Optimizely track individual users through the site? Does it use cookies, or assign a user ID, or both, or something else?

Re: User tracking

Hi there,


Optimizely uses persistent visitor-level cookies and localStorage to uniquely identify visitors, track their actions, and deliver consistent experiences across page loads. 


Read more about cookies and localStorage here.


I hope this helps!
