In order to have a sustainable marketing system, you need to implement MULTIPLE parts of a funnel.

Sam ovens once said, YouTube ads is to get people to know about you and your offer, and they work fast. YouTube organic is to get people to fall in love with you by watching your content, knowing, liking and trusting you. And then your emails sent to your list every single week is to remind people about you, your offer, and how you can help them too. And when you combine all three of these YouTube ads, plus YouTube, organic and weekly email, you nurture your audience and you get more people to actually buy from you more often. But most people just rely on ads, for example, but they skip the organic content. Or they're doing ads and organic, but they forget about their email list. It's combining all three of them, where you get the magic, and how you create a flywheel that consistently feeds your pipeline with high quality clients day in and day out.
