Well, if I have 100 sites making 1 usd per day. And of course when I reached 1 per day I will go for 3 per day then keep going and then yes 10 usd per day from each website 10x100 well we all have our ways to gain money. this is mine.
100 sites simultaneously?! Does one really have to do that? I think you need tons of articles to achieve that, and I assume you will buy most of them... Why not focus first on a single blog and make it earn $$$? Then afterward, make another blog and link to the first one, and so on. Is that your plan?
This is the way, I've tryed 75 sites simultaneously but it didnt really work out as great as I thougt I ended getting tierd of 70 sites and 5 sites got promo and made money but it took all my time to manage so many sites. This is the plan now. First create 1-3 sites and keep focus on them to start reciving daily organic traffic. Hopefully due to my great articles. Then when the sites are reciving enough traffic to make 10 usd per day in profit I will duplicate my idea untill I have enough websites for me to handle which probably will be around 100 and the profit would be pretty good. I'm writing it by myself, I love doing it so why not. But yes it's like you are saying, if you don't have experience of handleing massive amounts of websites stay and focus at one untill it's reciving a great revnue. Improve and Optimize! Money will come
