thanks man, my 3 sites are 1 year old almost.
i get the 40 backlinks scrapping the web and putting all those links in bmd .
i had one site which got 90k backlinks in 2 months
40 is a good number?
I don't put a limit on the number of backlinks daily. Natural backlink progression isn't staggered, so neither should your own efforts be. You can't control the amount of backlinks that your sites get....if it's out of your hands. I think it's best to mix it up and build a few here and there, and just keep it going.
