When a new website launch google put it into sandbox to varify the site, site did't crawl whenever website into the sandbox. After varyfying the website google crawl that site and put put some content into SERP. Actually Sandbox is mainly for google own box, Google is using this for own purpose it is not for any webmaster. Thanks
You have a point. Also you can check "sandbox" by typing your site title with quotations ("your main page title") in google search...
According to the theory of the sandbox effect, links which may normally be weighted by Google's ranking algorithm, not least improving the position of a webpage in Google's index, may be subjected to filtering to prevent their having a full impact. Some observations have suggested that two important factors for causing this filter to come into play are the active age of a domain, and the competitiveness of the keywords used in links.
