I have a site that almost over night dropped out of google? There where about 6-7 pages indexed the other day and now when I go to look there is 0. So im not sure if I got stuck in the sandbox or? I have been making alot of changes to the site(Took me a while to find the right cms, wiki, etc. so I was switching semi often). If any one knows what this could be due to I would really like to hear it. Thanks
It might be due to countless reasons, truly hard to determine but you may try to submit your question straight to Google support to see what happened in there.
Have you been doing serious backlinking? That could be the problem, especially if your site is new. Give it a week or so and then you will be able to diagnose the problem a little more accurately.
