hi mates, i am always building some K backlinks like article, wiki, web2.0, bookmarks, profiles,... then i blast about 100k SB links onto first tier. till now i couldnt see any good effects in indexing first tier with SB blast. can somebody tell me if its worth or not blasting Sb on first tier or should i ping first tier once a week? i tried links2rss but you can always just put 20links to rss. so if you have some k backlins you have to create a lot of Rss feeds.
