This has happen to me before a number of my websites disappearing for a few days after building a large number of links to them and they normally come back after a few pinging from a number of different sources..
I had build a number of links (200+) that may not have being indexed since I don't use any index services, I just converted these links to rss and ping the shit out of them and that's exactly what I did.
I am not worried that they won't come back but how long it with take because I recently start making some cents a few weeks ago..
What can I do to quicken their return....???
