If you can make a website and get some few or much traffic to it, that's fine but what if you don't have anything to offer for your site visitors yourself bc you don't have your own business or product or service? What to do then? How can you prevent such a situation? How to monetize that traffic then?
Yes, you know how to make a website but you're not able to really profit from it bc you don't offer anything yourself.
Isn't having a real business where you actually produce a product or offer a service much more lucrative?
