I have been ranking a new site for the past few months and I have gotten it to around 15 in Google for several keywords. I have been using SENuke the whole time. Everything has been cool until I got near the top 10 now the site seems to have hit some form of ceiling. I have been thinking of getting some aged high pr blogs and posting some backlinks there. As SEnuke thus far has only been doing third party sites I don't actually own or control. My question would be do you guys think aged pr 2+ blogs would give my site that final jump into the top 10? Or should I just keep nuking?
