I have some clients of SEO and Google has penalized them, after reconsideration request Google have given some example of unnatural links, one was a blog comments, second one was a Press release, third one was an article post on article base and fourth one was also a blog comments from a PR4 page. Google is saying to remove all these links. Then what are the remaining kind of links there to work on now ? How you'll get PR and what is the concept of link juice now ? and do we have to wait for NATURAL links only from now on ? I know the links we create are not natural and natural links are the only links which are created naturally by general user it self. Which rooms are open now to rank any website and with what kind of links ?
