I had a site that was getting about 3000 UV's a day until it was de-indexed by G00gle over 12 months ago. I was still getting a small amount of traffic from other sources (about 2% of the original) so I left it alone. Just noticed today that it is back in the serps and is a PR1 (Used to be PR3 but has been N/A for the last year). Traffic is starting to increase again. It has 12000 pages indexed on G00gle. I was under the impression that once you were de-indexed that was it. Have never heard of a site coming back from the dead before. I haven't made any changes to the site at all since it was de-indexed. Has this happened to anyone else?
