I launched a new website 2 months ago. Since then I've done: 2000 directory submission - about 100 approved, about 30 indexed 400 article submission (2 links each) - about 40 indexed 300 profile links - about 30 indexed 300 social bookmarking - about 30 indexed some blog commenting - about 20 indexed All in all, 160 back links until yesterday half of them have gone. But experts out there say that it's only temporary, so I hope it is. My question - is this low indexing rate normal? I mean, I aimed for 50%, so I built 3500, hoping that I'll get out with about 1500 links, but I only got 160 and half of them gone over night! Is this normal???
