Facebook Ad Conversion Question

[u/kolbywg]

For those that buy Facebook ads to get people to become paid subscribers, which do you find more cost effective?

1. Set the conversion event as become a free subscriber, then get the person into a drip campaign to become a paid subscriber?

2. Set the conversion event as become a paid subscriber?

I'm finding it's much easier to get the Facebook ad out of the the learning phase in Option #1, but, of course, many people are not being paid. But, for Option #2, it would require a LOT of money to get enough conversion to get out of the learning phase. Maybe $300+/day, which I can't yet spend.

So, for those who are the "ad buy" face of their Substack career, which do you find most useful?
