Hello guys, I keep seeing nofollow farms that my competitors use but am uncertain as to whether or not they would be considered spam by google. Since a good deal of them have links attached to them, I suppose google would consider them spammy but can't be very sure. I have seen pages that made their way to the top ONLY using these nofollow links so they must not be flagged as spam. Do you people have any idea how one can determine whether the page is spammy and will adversely affect your rankings or they would legitimately have a good impact on it?
