getting a high ranking page in google is just a short time is being penalized by the engine, even though the system of google in terms of Search Engine Optimization friendly links doesn't mean that you will instantly gain that high ranked page.
Google sandbox basically will just put your site away from the top search for around 2-3 months or at least before or after a Page Ranking update, but the links you put in or the links that are coming in to your site just somehow will not be considered, this may return but your page is somehow deep into engine. Actually, you can't do nothing else unless you make a fair play and build links and content on the time your site was in the sandbox, quality links are important, but buying links say thousands in a short time and your domain is just a few months old is not a good thing to make.
