A dropped domain has two Pr 6 directory backlink, one pr4 backlink...is it good? do you think page rank will update quickly??
You mean the site has 2 backlinks from a pr6 directory? Directory's have a very low value in google eyes, so i think they wont give to much linkjuice.
not exactly directory...one is review site and another is zoominfo.com and i took it , put up some content and it got indexed in 12 hours...
