Of course . absolutely agree with you! Quality is the first step to success!
Oh, there are many more aspects about the quality of the project, depending on which team, for example, and what kind of end result they want.
I will remain with one opinion that if the team has no desire to develop the project, but they buy advertising on the principle of "let it be," then there will be nothing
Its logical that the ad must be properly configured to work and attract new customers.
