Sandbox is an unofficial term used by search engine optimizers to explain the behavior of certain pages in a website on Google’s search engine. New pages or domains are often placed in an area by Google until it can determine or validate the authenticity of the page or domain name. Sandbox effect was first revealed in March 2004.
This placement by search engines away from the common search listings is called the Google Sandbox effect. Thus, these pages are not usually displayed for any keyword search. It sometimes takes weeks or probability months or years to get these pages into regular listings.
However, many search engine behavior watchers view Sandbox to be non existent and that it is just an imaginary assumption. They view it to be a kind of mathematical algorithm instead of a guideline.
Sometimes, if an individual page or website is in Google’s sandbox it can take a year or more to get them out of Sandbox and display them on a regular ranking. This has resulted in outcry among webmasters as even after following Google’s complete guidelines, they find some of their pages or domains land up in Sandbox.
Sometimes these pages are pushed into the “Omitted Results” category. In this case, we need to click on a similar description by Google in the last page of the search listings.
In order to show you the most relevant results, we have omitted some entries very similar to the ones already displayed.
If you like, you can repeat the search with the omitted results included.
Mostly, new domains suffer from this Sandbox. The worst part is we would not be able to do much about this. Rather wait and watch till it gets out of the Google Sandbox. However, it would be good to keep gathering external links pointing to the domain name and adding fresh content and multiple pages. This can eventually fasten the process of getting the domain or pages out of the Sandbox effect.
