Hi, Just developed brand new local directory site using wordpress platform. something like; NewYorkPlumberDirectory.com This is exclusive directory listing that the plumbing owner will pay to listed in my site. So, I need to make sure my site need to be on top at google and must stay on top. In order to keep my customer happy and stay, I need to make sure it'll not deindex by google, so I need to promote in white hat method. I do have few tools like scrapbox, AMR and what is the best way to start develop backlinks in white hat way. I don't want 1000 links at a time so my site get suspected. What is the reasonable rate?
