3 Websites on Page 1 of Google in 2 weeks.. now what?

Hey everyone, I'm happy then frustrated then happy again..

I mean, how great would it be to do the exact techniques every time to rank new micro niches? well heres my story (and my dillema)

I wanted to get into "sniper sites" so I ordered "google sniper 2.0"

So I started tossing out websites like crazy..
My first 7 websites went something like this..

Website1 - Page 1, #4 spot on google.
Website2 - No where to be found
Website2 - Page 1, #2 spot on google.
Website3 - Page 1, #4 spot on google.
Website4 - Page 2, # 15 spot on google
Website5 - No where to be found

Yesterday I made a total of $98.70 with 1 sale each from the 3 websites on the first page..

But it's still frustrating because if I could get those 2 websites ranking they are the real money makers.. but they are no where?

The point im trying to say is.. the method seems to work sometimes, and sometimes it doesn't.

All the websites have the same competition, it's not like one site is so much easier to rank then the other..

My biggest concern is, why are website 2 and 5 no where to be found?
If there was more competition, I would understand if im sitting at page 3-20.. but I can't find my website anywhere?

What are some possible explanations? I noticed on website 5 I repeated the same paragraph 3 times.. it sounds worse then it is but I was doing a "website review" and used it about twice and once on a different page. (fixed it though)..

I'll give someone my niche and website if they'd like to help,

Thanks in advance,

jeremy
