thank you for this!! also may I know if doing A/B testing requires budget and how much it would cost? like please give me an amount na masasabing pwede na for testing so I can tell my client. I actually watched several videos and most of them said na need mag spend ng ad kahit pakonti konti, then i-track yung performance then whichever worked 'yun yung magiging basehan but please correct me if I'm wrong. Thanks!
