Nowadays, you'll hear from people that SEO is dead and that you don't have to think or worry too much about it. But if they give advice, they're often talking about discovery.
If you're not aiming for search, Search Engine Optimization (SEO) isn't going to be as important. Meanwhile, for discovery, your packaging is the most important aspect.
What is discovery and search? Here's an example.

Imagine your viewer is going out shopping. They're not looking for anything in particular, but they're looking for something. As they're scrolling down the streets of YouTube, your packaging is like your storefront. It should make viewers think, "Oh, that's interesting. I'll pop in there and see what's available." That's what discovery (or browse) is all about.
Whereas with search, your viewer is looking for something specific. Let's say they're looking for some screws. They'll be in the screws aisle, looking at the signposts for where the screws are. This is where you want to make sure that you have the screws your viewers are looking for.
