Please Help Me Answer These Adsense Questions?

Hello Warriors,

I am a new member to warrior forum, though i am not new to IM, been in it for about 6 months now, also haven't made any good bucks...I am also currently a student studying Mechanical Engineering at the University, at present, i need some money so bad for bills and studies but my affiliate marketing isn't doing so good presently.

Right now, i am planning to go in to Adsense earning, i just believe that it could be easier to earn fast from that if i can do it properly. I have thought of it and i have come up with some strategies which i think i would like to share with the experienced markerter on this forum to guide me through if i should give it a go.

I am looking at making at least 50dols every day from adsense...I look forwards to start 9th of Feb. 2010 and by the end of Feb

My Stategies :-

I would be doing proper keywords research and try to find some micro niche keywords with searches less than 50,000 no more than PR 3 on the first result of SERP.

I am looking at targeting about 50 different micro niches keywords thereby creating 50 blogs...

I will then head up to godaddy to purchase a .info doman for the 50 keywords i have chosen.

As for the content for the site, i am looking at autobloging. because i wouldnt have time to service the blog if i am doing manual posting of content due to school work..

For the autologging content, i would be using powerautoblog by Edwin Ann.

For Promotion, I intend to use Traffic Geyster or Content Buzz, Social Submission, Rss Submission, Pinging..... I intend to do all this in 1 week for the whole sites i am promoting for the adsense.

My Questions

Since i would be using duplicate content, Would my sites suffer set backs in the big G?

Also, i would be using a .info doman. Please any advise on wether .info domains can still rank 1 st page on G if promotion is done correctly.

What other ways would you suggest for me to promote this adsense sites for quick indexing and appearance on top 10 pages of SERP with my keywords with would be less competitive.

Your great ideas, suggestions would be highly appreciated.

Regards,

Remmy..
