If you add free articles you will never make it good in search engines, so I wonder how will you make loads from adsense.
If you can update all the blogs then this is a great idea. but if you will leave the blogs and will not update them, then you will not be able to make much money.
Absolutely right. I suppose the only way to do it would be with 'paid for articles'. That would change the formula to: 1. Create 100 blogger sites (various topics, maybe some hot topics like the olympics etc). 2. Add weekly paid for articles. 3. Add the adsense ads in the right places. 4. Build links to the sites.
Interesting content, a good niche, and traffic will get you the loads of adsense money that you are looking for.
