Quick question, How many impressions/reach/clicks per ad until your test is said to be statistically significant. Struggling to find a practical answer online. Tried using A/B test bayesian calculators and other shit and read articles saying you need hundreds of thousands in traffic, which is likely $xx,xxx minimum in ad spend. Other people say use the chi-square test, which I learnt before in stats but kinda forgot now. But I'll learn it again if it's necessary, shouldn't take too long. Obviously I'm starting out in this internet money game so I can't afford massive spending, but I want accurate data so I can implement and execute quick. If you need any more info about my ads/business/etc to have a better answer feel free to ask. Just not giving away my actual site URL. Thanks guys.
