What is the Google Sandbox, and is it real?
The Google Sandbox theory suggest that whenever Google detects a new website, it withholds its rightful ranking for a period while it determines whether your site is a genuine, credible, long term site. It does this to discourage the creation of SPAM websites (sites which serve no useful purpose other than to boost the ranking of some other site). There is a lot of anecdotal evidence supporting the theory, but there is also a lot discounting it. No one has categorically proven its existence.
