Define clear objectives and optimization strategies for every video you publish.
Yes — one primary goal per video. Multiple goals dilute your CTA and confuse the algorithm about what action you want viewers to take. Pick one and optimise everything around it.
2-3 times per video. Once at 30% (when engagement is high), once at 70% (before viewers leave), and once at the end. Don't mention it in the first 30 seconds — build value first.
Grow subscribers until you have 1,000, then shift to building your email list. Subscribers give you reach, but your email list is the asset you own.
