While working on soon-to-be-released projects there has often been a need to make a staging/testing website publicly accessible for client testing. This is a slippery slope if search engine spiders get in and index your site before the rest of the world is meant to see it (it happens more than you’d like to think) – If it happens to be a website you are building for something that the rest of the world shouldn’t see yet such as a product/service launch, having it leak too early can often make or break you. They have a word that describes this very fear of spiders  – it’s called Arachnophobia.
