You work hard for months or years building up a website. It's now very popular, producing a decent income for you as well as providing a useful resource that a large proportion of your visitors bookmark and return to regularly. Then, one fine day it disappears from page 1 and tumbles down to the nowhere land of page 6. Your income has gone, your business is in ruins. You suspect a manual penalty so clean up the site and submit a reconsideration request which is answered a couple of weeks later by a standard email implying that your site still breaches certain undefined guidelines and, well, hard luck mate. You have no idea what the problem is, the Google forum provides a multitude of conflicting opinions, your savings are running out and the bills are overdue so; what do you do?
Has anyone ever got a site back into a decent position in the SERPs after a Google ban? If so, care to share details of just how you did it?
