I am working on a new project and I think I moved too fast.And now my homepage disappeared from googles index.All of the other pages are there but my homepage does not even have the cache. I know this is a kind of penalty cause I had this before on another site , the home page came back 6 months later and it began to rank after 2 years any idea to stay away from this penalty and how to recover fast ?
If there is no cache of the page then your page got de-indexed . There could be like 1 gazillion reasons. Maybe dublication.
sandbox is a ordeal for new site, during this period, take it easy and be more careful, then you can make it through favoringly.
