Google’s Sandbox, Trust Rank and Domain Age Filter
Three Google filters that all take a hard look at the age of your web sites. Most web sites aren’t very old, and so, Google implemented a filter that prevents new web sites from getting high rankings for competitive search terms. Google’s calls that filter the Sandbox.
Google’s TrustRank filter is closely related to the Sandbox filter. Web sites with a high TrustRank get high rankings on Google search. The TrustRank of a web site is determined by the age of the web site, the quality of inbound links and the unique contents of the web site.
The third filter is the Domain Age filter and that filter considers the age of your web site. Web sites with old domain names are far more likely to get higher rankings for competitive keywords on Google.
