I was wondering if I got a high pr but irelevant link, would it be woth adding some relevant disguised text to make the link seem relevent? If you know what I mean....
No way man, don't base your entire keyword optimization around just 1 link.... Links come and go! Good Luck!
Not worth putting all your eggs in one basket, that's for sure, not on the internet or anywhere else. What a lesson but most people never learn it. Throw all their money at one investment and lose the lot - everyday.
