A couple of months ago, I started a site targeting a certain keyword because after analyzing the site that was ranking #1, I realized it wouldn't be too hard to get the same backlinks it has. After about 1 month, the site was ranking on the 4th page. In the second month, I managed to get almost all of the backlinks that the site ranking #1 has got (a lot of the links from "resources" pages or similar), plus some more links from guest blogging on authority blogs. But even though the site has sufficient backlinks to rank on the first page, if not #1, the site is still ranking on the 3rd page (it hovers around #28 - #31). The keyword it's targeting gets 2400 local searches per month and 3600 global. Could the sandbox be to blame for its low ranking? All of the sites that are ranking above it have been around for over a year and most have been around for over 3 years. Should I just wait for my site to age more or should I keep building more links?
