I am using socialmarker to submit to all of those social bookmarks on there. I'm only submitting 1 post per day and I was wondering would google start getting suspicious because it might think it's spam due to high amount of backlinks?
you don't have to worry as your doing just one post.... but ensure you get links from other sources as well (directory submissions, blog posts etc)
Yup, SultanofSeo (lol awesome name man!) is right on the money 20 Do-Follow back links a day is more than acceptable
