Bit of a conspiracy theory here, but let's see what you guys think.
I have a new site (spanking new). I also have 5 related sites that have some authority.
1. Submit that new site to Google for indexing.
2. Let Google find the sites through links from the authority sites.
At a recent conference a presenter claimed that he saw deeper crawls when Google found sites, than when they were submitted to Google.
What do you guys think?
