Can Google Spider Discover Web Pages With No Inbound Links?
I believe only way for Google to determine the new domains is through the registry information. I'm not sure whether the domain registrars share the domain registration information with Google (they should not, actually). But a new domain IP might trigger Google's spiders to check it out.
Now consider a new web page added on an existing domain. Unless specifically blocked by robots.txt file entry; Google will figure out all the links by following the links on the homepage. I doubt they can discover random pages on the domain that haven't been linked by anone, not even the home page.
What are your thoughts on this? Can there be a mechanism to discover the web-pages that don't have any inbound links?
