Once you submit your test, your test will typically require 6-12 hours, but up to 24 hours, to reach Confident Results.
Approval time: Once you submit your test for Facebook review, Facebook typically requires 1 to 4 hours to approve your messages.
Run time: After message approval, Facebook typically requires 4 to 6 hours to reach Preliminary Results, and 6 to 20 hours to reach Confident Results. Run time can be notably longer at night because fewer people are online.
Status Notification: Naytev emails you when confident results are ready; ensure you receive this email by confirming your address under Account > Preferences.
Facebook controls the test pace, but you can sometimes accelerate the pace by up to a few hours in two ways:
Reduce the number of test messages (e.g. text 6 instead of 12 messages); this can reduce test performance, since fewer test messages are evaluated.
Increase the test budget (e.g. double your normal budget)
You can safely use both of these techniques for the same test.
Important: Reducing test time doesn't accelerate pace, and may result in test failure.
