Hi. I just got hands in a blog that have good reputation (a wordpress blog with 41 Page authority) and good links point to it, but isnt updated since 2011. I want to use this site to boost my site, so what the best options? I don't want to make a new post because this will attract some attention that I do not want. The public that visit the old site is not my target audience, so I just want the link juice, not the traffic. In some posts (2 or 3 of 700) I can modify a little bit and put my link on it, because it have the keywords I want rank for. So if i update it will google find it? It will work? And should i delete the links from all the old posts, so the link juice flow more to my site, it works like that? Thanks!
