I think you have to keep adding content in your site in order to get traffic from search engines. To start with, 100 pages site is good. But I suggest you keep adding more content.
I would say you would have to make a ton of sites if you wanted to make some serious income, and I am talking in the tens of thousands! It's really hard to get visitors to your sites but if you make 100 sites that have consistent organic traffic from top search engines, you will do fine!
Icheb, does it cost you money to make a polite reply to members here on Digital point? After all, tjsocr22 is giving his own opinion and not acting as if "he is a know it all". Bro, I suggest that you don't participate in threads where you have no constructive contribution to make. Simple as that!!! And yeah, tjsocr22's suggestion is a good one, except that it may be very difficult to put it in practice in real life (but not impossible). By the way, I agree with desilator. Creating a "network of sites" would be a good choice....
Your 100 pages site with articles has nothing to do with how to earn cash online. Though a site is very simple you could still earn an income. The important is how you can drive traffic to your site. No traffic No money
There you go, a complete answer in a few words. This is one of the best practical method to earn money. Nice first post mate.
