Is advertising for followers effective?

[Hashigato]

Hello friends. I am planning to get into follower sales business soon. The domain has been purchased, and hosting has been arranged. I will be getting a package sales script for around 200 TL soon, I believe. I have set aside 100 TL balance for Adwords to advertise the site. As revenue comes in, I plan to use all profits from the site for advertising. So, if I spend 100 TL on advertising, how does this work? Can you enlighten me on this matter? At the moment, my budget is suitable for this. Perhaps I will benefit from the ads I run there, and then I can provide full ads for the customers coming from there. It will be a social media package sales site.
