What is Google Sandbox?

[Jeffreyhooft]

The Google Sandbox is much related to a new website being placed on probation, and kept lower than expected in searches, prior to being given full value for its incoming links and content. The Sandbox acts as defect experimentation for sites, possibly to put off spam sites from rising quickly, getting banned, and repeating the process.

Google Sandbox is an imaginary area where new and less authoritative sites are kept for a specific time period until they establish themselves of being displayed on the search results. Its generally happen due to building high volume of links in short time.

It may seem that the Sandbox is unfair to newly launched websites, but Google created the Sandbox with good reasons. Google was trying to discourage spam sites from quickly reaching the top of Search Results, getting dropped off Google, creating a new site and repeatedly showing up high in Search Results.
