People say SB helps index backlinks but from experience I've found that is only sometimes true. I.e. I would blast profile links and AMR links night and day with SB and they wouldn't budge. On the other hand I recently did a test of blasting only 7 of my self hosted wordpress blogs of a 10 cluster for backlink energizer. I'd made them the same day and 3 were already indexed from before as I made them 1st and blasted them. Of the 7 left I went to bed and in the morning 4-7 were indexed but 8-10 (the ones I left out of the blast) were not. So a fine split test if I do say so myself. So I'd say SB etc. will help with indexing but just when google would be sniffing around those links anyway...to push them over the edge I guess.
