Lately lot's of people had issues with indexing links, even me, but I've noticed something. My handmade Web 2.0s wont index while my shitty blog network with pure crap, spun text are getting indexed and even ranking, without backlinks. Few days ago, on the 19th I bought an old deleted domain. Registered 2007-04-01 and Deleted 2009-07-01....been dead for over 4 years. I changed the theme, the title and changed the header and suprise, suprise, it's indexed, with no effort from my side and the Welcome to Wordpress as only post. Are you wastin' tons of money & time building Web 2.0 blogs and having hard time getting them indexed? Try dropped domains with history.
