2 new blogs that Google spiders very differently

[bluemi]

This is my scenario:

2 basically brand new Movable Type installations on different sites and different servers. When posting to the first blog Google picks up the posts within minutes, I can almost immediately see them in their index.
3 days ago I started posting on the 2nd one. No error message when pinging but even now not a single post appears in Google. How can this be? I thought about the server blocking pings but pings to Technorati went through. The strange thing is that the blog that doesn't get indexed sits on a site that is much bigger and much more active than the other one. I really don't get it...

That is a curiosity. My first thought was definitely that Google isn't getting pinged. How is the rest of that bigger site doing in Google? And are there any crawling problems mentioned in its Webmaster Tools account?

If link profile is similar I have a silly theory about trusted IPs / hosts. Some are more/less trusted by Google hence crawling / indexing / sandboxing differs. There's also the topic question ... how much competition is it out there. No two sites are the same and discrepancies may appear just due to their topics.

Maybe just a brain phart;)

tedster: I had a few redirections in the forum that Google didn't like but I don't think this was the reason and it's the only problem I saw in Webmaster Tools.

5ubliminal: Both have their own unique IP but yes, the bigger one has quite a bit more competition. Interesting thought.
