What is Sandbox? Why Google introduce it.......????

What is Sandbox? - The Google Sandbox is very similar 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.

Google Sandbox is launched in March, 2004. "Sandbox" theory suggests that new sites will be added to the Google index and may even show up for obscure searches such as the company/web site name but will not show well for other phrases that are relevant to the site. It doesn't matter if the site is optimized for the search engines either. In fact, those who have optimized their sites can drive themselves crazy making change after change but to no positive avail. The Sandbox acts as a de facto probation for sites, possibly to discourage spam sites from rising quickly, getting banned, and repeating the process.

Now you must thinking - Why did Google institute a Sandbox?

Because, It is thought that the reason Google created the Sandbox new site filter was to stop spam related sites from adding numerous purchased links--and ranking highly for their keywords from the date of launch. Since Google apparently considers a high number of links pointing to a site from the beginning to be rather suspicious, the links are not considered to be natural. Another possibility is spam sites would use various tactics to rise to the top of the search results, and gain heavy sales prior to being banned for being in violation of Google’s Terms of Service; and then repeating the process continually. As a result, new sites are put into a form of probation, usually referred to as the Google Sandbox.

My site has never been in the Sandbox. Why not?

You can avoid having your site in the Sandbox for several reasons. If your site was launched before the March 2004 Sandbox filter, your site probably avoided the problem. Sites targeting non-competitive keywords and phrases are often left out of the Sandbox as there is little point in applying the filter. Keep in mind, however, that even less competitive search terms can be Sandboxed, but their much shorter stay can often go entirely unnoticed. If you had ownership of a domain prior to the installation of the Sandbox filter, your site might also be spared its probationary period.

How long the sandbox’s duration can be?

Stays in the Sandbox can vary from one to six months, with three to four months being the normal time frame. Less competitive searches will be given the much shorter stay, while hyper-competitive keywords will often spend six months in the Box. The most frequent length of stay is about three months for most search terms.

Are there variable lengths of stay in the Sandbox?

The stay in the Sandbox is highly variable. The more competitive the keyword, the longer the site spends in the Sandbox. The filter will be gradually decreased over time, and will lose most of its dampening effect in about three months. Of course, for the most competitive search phrases, the Sandbox filter might remain in full force for six months.

How do I know if I am in the Sandbox?

You can look for evidence of Sandbox activity. Does your site have a strong Google Page Rank, along with good incoming links? Does it get excellent search results in some secondary search phrases? Then, if your site is still nowhere to be found for the most important searches, it is likely the site has been placed in the Sandbox. If a site were suffering from a Google penalty, the site would not appear in the Google search engine results pages (SERPs) for even the less important searches. The site would also show no PageRank -- not even a grey bar on the Google Toolbar.

What should I do while my site is still buried in the Sandbox?

While your site is in the Sandbox, it’s an ideal time to continue to add fresh keyword rich content and new incoming links to your site. Adding incoming links will ensure that they also avoid any possible new link dampening filter that might be in effect. They would be well aged and ready to pass along their full value of PageRank and link popularity as the site rises from the depths of the Sandbox.

Should I continue to add content to my site while it's in the Sandbox?

Your website’s stay in the Sandbox is an ideal time to add more theme relevant content. Concentrate on adding more keyword rich pages, and don’t forget both on-page and off-page factors. On the page, make sure your title tags match the most important keywords for that page. Add a site map and make sure that your entire pages link properly to one another with appropriate link anchor text containing the keywords for that page. Off-page link anchor text should be set up to include keywords for the receiving page as well. Don’t waste any of your available site improvement time while in the Sandbox. When the filter is lifted, your improved site will rise rapidly to its proper place at the top of the search rankings
