Definition of Google Sandbox
Google Sandbox refers to a hypothetical mechanism that factors a website's age (or lack thereof) into its ranking on popular keywords.
Around the end of 2004, many website developers started noticing that sites that previously took 4-8 weeks to get indexed and ranked by Google were suddenly taking much longer. People surmised that Google put some new sites into a "sandbox" until time and other factors indicated that they had been around long enough to be indexed. Google denies the existence of a rigid sandbox rule. Many of web marketers have observed effects and talked to knowledgeable people that lead us to believe that the sandbox effect is not discrete, rather that website age is being made more important among many other factors for determining website ranking. This is somewhat of semantic argument since most websites seem to take roughly the same amount of time to be indexed: almost a year.
