When new sites are submitted to search engines like Google, Yahoo! and MSN, they are placed temporarily in a sandbox for three to six months, during which the website will not surface on any of the top search result pages, inspite of having excellent content, or inspite of having numerous quality one-way inbound links pointing towards it.

This is done in order to discourage spamming websites which are created with the sole objective of providing links to an affiliate business, but contain no relevant or sensible stuff for the readers to read, comprehend and derive benefit from. These spam sites somehow manipulate the search results and manage to land right on top of the search pages. This is when the website makes a lot of profit through affiliate business but eventually, their page rankings fall miserably. At this time, the webmasters of such unscrupulous spam sites collect all their earnings and wind up to set up several more such similar spamming websites. It is like a vicious cycle, with the spamming sites being abandoned after making enough money out of it through affiliate marketing.
 
This is when the idea of the sandbox effect was introduced. The sandbox retains each website temporarily for a few months during which all authentic websites tend to improvise and develop their content even more. It is an inevitable wait, after all, and all you can do during this period is to improve your website continuously.

1. You can feed your websites with more relevant and meaningful content, which means that you can provide blog posts, article submissions or RSS feeds on a continued basis to this webite so as to feed it with fresh topical and thematic matter everyday.
2. You can improve the web content matter of your website,
