Autoblog/Micro Niche Site Advice

Hi everyone,
I have a question regarding how to generate profitable passive income from these 2 forms of sites. Autoblogging is great for constant updates and new posts but it is time consuming to trying out and implementing the right plugins to monetize. On the other hand, basic micro niche sites are very simple to put up (taking the example of 4 slice toaster) and its simple adsense positioning and layout. Though keyword research is the key to any project, wouldnt basic html type micro niche sites be more targetted (like 4 slice) rather than autoblogs that are lacking articles about a specific niche if not a micro niche?
Any ideas or wisdom you'll like to share?
Thank you!

There are some good threads in the adsense section on micro niches, take a read. You're in the right direction

Think about integration of one into other. Tol'ko chto zametil nick tvoy))

Think about nanoblogging. It's a smaller blog that focuses on the micro niche but doesn't update. Can be much easier to put up than html sites.
