What is Google Sandbox?

Very good question

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.

Even with good content, abundant incoming links and strong Google PageRank, a site is still adversely affected by the Sandbox effect. The Sandbox acts as a de facto probation for sites, possibly to discourage spam sites from rising quickly, getting banned, and repeating the process.

Holding area and have their search ratings on hold until they can prove worthy of ranking. The newly registered domain is put into holding area (sandbox) and their search ratings on hold until they prove worthy of a ranking.

Thanks for your reply

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.
