I've got a new website that I want to rank "city[keyword].net" in order to rent out advertising spaces to local businesses. I want to get it higher in the SERP but it's a brand new site. It's an easy keyword to rank with little competition other than some local business websites with a no SEO. I was thinking about waiting a week or so and buying 10-20 high PR backlinks from Fiverr. All on-site SEO has been done and I'm only looking to rank one keyword. What do you recommend in order to quickly get me ranked onto page 1 without getting sandboxed?
