If you get USA traffic then you can make more than 30$ per month with 1k daily traffic. As @xcodes says use banner ads and video ads. Also, you can use popunders too and it helps to earn more money but I personally don't like those because visitors hate it.I got 1000 per day from seo. How much traffic need to earn money? Which other traffic can I use.
I heard that pupunder is terrible for SEO. Is it truly? And how much money need to start using pupunder?
