Nelio A/B Testing uses the following cookies:
nabAlternative. This cookie stores the variant a visitor is supposed to see.
nabSyncStatus. Nelio A/B Testing only tracks conversions if (a) a conversion action occurs and (b) it occurs after the visitor has seen the tested element. This cookie keeps track of the tested elements the visitor has seen and uses it to decide whether a conversion has to be synched with Nelio’s cloud or not.
nabParticipation. Visitors may or may not participate in your tests. This cookie keeps track of that.
