That is an argument that can be made in favor of
Thurow's comments as noted on the SEOmoz blog in a recent
post:
There is no such thing as a Google Sandbox. It's one of those terms
that self-proclaimed search engine "experts" came up with to explain why their methodologies don't work.
Michael Martinez, who posted Thurow's comments as they appeared on LED Digest, agrees with Thurow and
Mike Grehan that the Sandbox
per se does not exist:
I don't believe that Google intentionally sandboxes all new Web sites. I do believe that Google has admitted, more than once now, that there is an unexpected effect that they sort of like and have no desire to alter.
The effect requires you to work harder.
