I've made a new site, submitted it to Google and kept checking to see whether or not it had been ranked for the following days. 4 days later, to my delight it appeared that Google had "shallow" crawled the site and indexed the index page, as whenever I searched for my url (without the .com or - bits) it appeared as number one. Good start I thought and I even had a page rank of 0. (as oppose to nothing) Whenever I copied some text from the index page and pasted it into the search box exactly... the index page was displayed from the search.
To my horror however, the very next day (around the 27th June) my site is absolutely no where to be found in google and hasn't been ever since.
If it makes you feel any better, the same thing has just happened to me with one of my new sites. Hopefully in a day or two it will reappear. Some of my sites are also showing no links now, even though they have at least 40 or so and google was counting them last month. Anyone else have this happen?
