The Google “Sandbox” or “Age Delay” Filter

I have read many articles and speculations about the so-called Google “Sandbox” or “Age Delay” filter, from what I have experienced it seems that such a filter does exist. Performing a query for allinanchor:”personalized children’s books” which is the top keyword/phrase I am targeting results in the site being listed on page 2/3  yet querying for keyword/phrase “Personalized Children’s Books” has us on page 18/19.

So how long does this filter apply? How long will the site be “Sand Boxed”? No one really knows the answer to this, but the speculation is that for new domain’s with similar content / material Google wants to keep the ”Age Delay Filter” for approximately 6-12 months. Is this fair? I am partial to both opinions it will help reduce spam sites ensuring the site/domain is something that is going to be around, but on the other hand legitimate sites will take a penalty for quite some time reducing the potential traffic.

Let’s see how long Google makes our site play in the “Sand Box”.
