After reading this post http://www.blackhatworld.com/blackhat-seo/black-hat-seo/102150-how-i-generate-around-five-pr3-5-backlink-day-15-minutes.html I started to look for some juicy backlinks and i found something that make me feel a little confused. Suposedly google drops backlinks from expired domains but if you look closely at this domain samirkuntar.net it was dropped, then buyed in 2009, but all the backlinks that google shows are from sites that links to it previously. So are google really dropping backlinks from expired domains???
Nope, Google counts those backlinks. If you are using the link: command be advised that it is not accurate.
