I would like to give some hope for you guys that may think your new sites were already banned at Google after weeks or a month being indexed and now no where to find it at google index. It probably in Google sandbox. At first I panicked like you guys. I never thought my 7 new launch sites will be vanished at Google search results after being indexed for a week or two. So I started a thread rant here http://forums.digitalpoint.com/showthread.php?t=1244634 to hear some of the member’s opinion. At first I almost lose hope that my sites will be back and also for my new projects but I still manage to follow some of the comments of the members that my site is just in sandbox and will be back it time. So what I did is just build backlinks for my site and after 2 weeks my site is back again http://www.google.com/search?q=health+site+directory&pws=0&gl=US ! So I advice to you guys that don’t lose hope when your site cannot be search on google even you typed your domain name. It will be back. This applied on new sites only.
i dont think your site is sandboxed at all. google bounces your search results alot when your site is under one tear old.
I just registered that domain last february 10 see the whois info if you have doubt http://whois.domaintools.com/healthsitedirectory.com Here is another example http://www.google.com/search?q=startingupaclothingline&pws=0&gl=US yesterday the homepage of my site didnt rank for its domain name. but now you can see it on the first position. My other sites are dramatically getting indexed again.
