In your strategy (1):
You suggest a niche site of 100 pages.

When I said 100 Pages of content means websites and not blogs even though it should be updated, but not often as blogs, If you can write 100 unique articles for a particular niche on that website you can get some good decent traffic if you have optimized your adsense content properly you will start earning quite a good amount of money from adsense.

In your strategy (3):
Please define “network of blogs”. What constitutes a network, in this strategy?

Here I meant a group of blogs, If you can build few blogs on the topics which you like to write it can get constent traffic to your site. So having a network of sites is the key to this strategy.

Thanks

Does a site built on a WordPress platform with 100 posts–that are not updated with new content–constitute what you are talking about?

I am seeking understanding.
