Is it worth launching an Internet project (game portal) if several modules have not yet been fully completed on it?

Question

Search Engine Optimization

Somewhere it was said that even it is necessary.
What are the advantages of this?

Answer 1

You can start, you need to start, but you should not invest in advertising until you are sure that everything is working at 99%. An early launch gives you the opportunity to get at least some statistics, show the work to a wider circle of people (for the purpose of additional testing), and finally get some feedback from real users.
