Is it good to start Amazon affiliate website in 2019

No because now a days no one like to surf the website and buy from the web version because everyone is having a smartphone and they use the App and affiliate links do not work when someone make a purchase from the app. But for some companies it works but still commissions are reduced and government is making so many new rules regarding discount and cashback and many other areas. I am not saying that you will not be able to earn but after a very hard work you will earn average returns. You may not get a very good response but you will definitely get average returns.
