Hey...
you gonna do it now.. cause maybe next days its too late...
go to blogger.com (from google)
create many blogs with your wish niche...
example:
your-keyword.blogspot.com
Then add 3 Sites or more with Post/ Content about your niche
Add a long text.. over 500 Words...
do a right internal linking with anchortext in post text.. but not over 50... linking all 3 post or more together with internal linking.
DO NOT EXTERNAL LINKING TO ANY SITE! ONLY TO BLOGGER!
Disable Comments...
Bookmark, ping it... do a little bit SEO to get the googlebot on your site to index your content...
linking to your blogger site from ONLY high PR Sites, but not too much...
Now leave your site for one or more years...
I did this way and I get after 1 Year (without any work or blog updates) a High PR3 SEO Blog...
I did it cause I was doing SEO for a very old P*rn Site which is not alife today...
Now I using it for myself to write related content articles and linking to my blogpost..
