I have been a member of this forum for some time lurking around and reading the particular reason, I started reading. I have several web sites about six months ago one of my web sites ranked on the first page of Google disappeared to the 18th page. Another web site that I had also on the first page of Google ended up on the 22nd page one morning. About two months ago The sites are in small niches and had been ranked there for quite some time. So I set out to find out what happened. I am already quite familiar with a lot of techniques so I suspected What had happened. I wanted to find out if there was a way to protect myself from it happening again The best way to find out if I could protect yourself I had to find out if I could do it that is destroy a site ranking. I built a couple of small sites on some small niches got them up to the first page on Google. I picked a couplet of niches that I had tried in the past and they were not profitable for me. So when I try to destroy them it would not break my heart. It took about 2 1/2 weeks to get them up on the first page. And then I went to work there's a few things I tried but it did not really affect the one site that much. I had to do this all from my desktop no ftp. access to the site at all I was able to do it with the second site quite dramatically. You can see by the picture I uploaded I was getting about 90 visitors a day in this little niche. I then took it out from my desktop it is now on page 18 and you can see the traffic went down to 27 visitors on the 9 of October and now zero on the 10th of October. So now I know how to destroy somebody's rankings the best way that I found was to start adding back links relative back links work better increase their velocity start out with 10 or 20 a day next day 40 to 50 a day Increase it to 300 and 500. During this time the site will actually start to do better.This process is about a weeklong the site will continue to rank well as long as you do not it is the sudden stop that kills it the velocity simply ending. Go from 400 to 500 links a day to 0 Two days later the site was on page 18. My question still remains though is there a way to protect myself I haven't found one.
