I've learnt something very valuable about the freemium business model from YouTube. If you're going to run a freemium model and your key metrics include DAUs, then make sure your free trial is up to 30 days. (1/5)

Anything less than 30 days can easily become a waste of resources. It doesn't give the users enough time to
familiarize themselves with the product. (2/5)

Remember, this is if DAUs (Daily Active Users) is part of your key metrics. For example, because I use YouTube daily, I'm constantly reminded of how valuable YouTube Premium is compared to the regular version.

This makes me more inclined towards paying for a premium plan. (3/5)

If the free trial was only 7 days, I wouldn't have enough time to internalize all the benefits, so I'm more likely to make a quick and less-informed decision to not sign
up for the premium plan. (4/5)

So, give users enough time (preferably a month) if you're going to run a freemium model and DAUs is part of your metrics.

I keep emphasizing on DAUs because if, say, MAUs is your metric, then that's different. (5/5)
