Martin,
Google sandbox exist for real from my own experience. Do a search in your favourite search engine and you will find lots of info on Google sandbox

The Sandbox is not so much a single thing, it is a series of events that result in your site being held back.
It CAN be beaten, but for that.... you must pay ... (as the advert says ) LOL

i agree with old welsh guy. the sandbox isn't a mehanism google specifically invented. tis just a combination of factors that stop new sites for less traffic keywords getting indexed.

Its good to give a break once you buy a domain name, if you design your site say after 3-4 months you might have no longer waiting.

i thought the sandbox started for when googl first crawled your website. so, waiting 3 months before designing the site would just add 3 moths onto the wait?
