IF you are a webmaster and you didn’t hear about the sandbox before, let me make a small prevision about sandbox, sandbox is a temporary penalty imposed by search engines on the new websites witch prevents them from showing in a good ranking with search engines and some times showing no where in the SERP for a long period.
The first question that may comes up is how much the period that the search engines may keep your site in the sandbox, actually the answer for this question depends on many factors:
1- Which search engine you meant in your question, this period is short with MSN some times it is around one month, while it is about four months with Yahoo, with Google it may be extended to more that one year.
2- How match link popularity does your site have, the more inbound quality links your site have the shorter time your site will spend in the sandbox.
3- How much competitive is the keyword that you are targeting for your website, definitely if you are targeting a long term with no competition you are not going to stay the same time as if you are targeting a competitive keyword.
There is something you should always remember, that even if you are out of the sandbox you still need more age for your site to get more trust from the search engine and eventually ranking will and this point is easy to notice with Google.
Here I want to list example for the effect of sandbox, on of my sites www.searchengineoptimizationtoronto.com which is still relatively a new website (About 4 months of age), obviously through this website I am trying to target a long term which is search engine optimization Toronto and the mission looks easy as the domain contains all words, but now after checking the SERP I can see it for the term search engine optimization Toronto:
First spot with MSN, first page with Yahoo, still no where with Google.
Then when I know that my website is in sandbox so what to do??
First thing be patient nothing serious happened, just keep working on your site, and try to make it useful to the visitors, update it regularly. Try to improve the link popularity of your site by getting more inbound links from quality related websites (That is will shorten your stay in the sandbox).
If you really got enough headache reading about sandbox and you don t like to go with your new website through it, then simply buy old website that meets your business with about 2 years old or more and you can save yourself that entire sandbox’s headache.
