Hello World. A site that I put up around a week ago using John's (XFactor's) method was indexed and ranked at number 5 within 24 hours of building it (and it got me one Adsense click). But afterwards, the home page was removed from the index and now just recently the whole site is now gone. I have NOT done anything wrong with this and of course I avoided showing my site to anyone. Should I worry about this? And do I need to resubmit my sitemap or something?
