What is Google Sandbox?
 

Can any one explain what is Google Sandbox?

The Google Sandbox is an alleged filter placed on new websites. The result is that a site does not receive good rankings for its most important keywords and keyword phrases. Even with good content, abundant incoming links and strong Google PageRank, a site is still adversely affected by the Sandbox effect.

The Google Sandbox Effect is a theory used to explain why newly-registered domains or domains with frequent ownership changes rank poorly in Google Search Engine Results Pages (SERPS). In other words new websites are put into a “sandbox” or a holding area and have their search ratings on hold until they can prove worthy of ranking.

Simply, if your website is penalized by this Google's algorithm, it will never appear on google search :D

Usefull infomation, thank you.

The Google sandbox or “sandbox effect” is a filter that Google applies to new websites that want to rank in the search results for specific phrases. The filter exists to prevent SEOs and spammers from easily manipulating search results by satisfying all of Google’s major offsite and onsite factors.

Google Sandbox is viewed by many as a probationary period forced upon new websites that prevents them from shooting to the top of search engine results.

The sandbox is essentially a filter that was created by Google to avoid spamming of search results by unscrupulous webmasters. Before the sandbox was created, most new sites could rank pretty quickly, which allowed certain "black hat" SEO professionals to make a quick buck by ranking a new site on the top of Google's index for a very competitive keyword, and then cashing out before Google caught up with their spam technique.

Google sandbox is an imaginary area where less authoritative and new sites taking place while they are popular and authorized on the web.
