I went to bed last night and woke up with my site on the second page of google blogsearch for the terms: jay z mandy moore I only made those posts last night, did no advertising and I got like 10 hits from google so far. Hopefully my next posts are indexed as quickly.
Blogsearch does not bring any traffic. I rank #1 of blogsearch, but have not received even a single visitor from there...
Maybe you should say "Blogsearch brings little traffic." as I just said in the post directly above yours that I have recieved some traffic.
I think there is no definite ranking from Google blogsearch for time when was the content was posted was an attribute there to show result. Thus the earliest one is on top, when the post aged, it goes down as well as new related topic came which conquer the top. There's no definite traffic from Google Blogsearch.
