Okay I try to teach you fast:
1. type in Google:
* inurl: Your-Keyword “This site uses KeywordLuv”
or you can also type
* inurl: Your-Keyword “Enable CommentLuv”
Examples:
2. Visit the first 10 high ranking Sites/ Blogs at Google Results on your wish Keyword you typed in
3. Comment on these Blogs and link them to your Post wich used same Keywords
4. Maybe you can send a Trackback to these Blogs or Websites
This is a Way to find blogs with same content and you can generate high Quality Backlinks.
If anyone dont know what KeywordLuv is or want more informations you can read my post about this: Backlinks kostenlos generieren mit der "KeywordLuv" Methode | SeoBunny.de
