Welcome to WebmasterWorld Guest from 126.96.36.199
But I found a site containing a sub directory displays sitelinks.
A blog of the most famous Googler has them when you search his name.
An address of his blog is "www.his-name.com/blog" not "www.his-name.com"
(its domain root ranks #2.)
Is this ordinary or exceptional?
Is this because the blog has got much more authorities(links) compared to its domain root?
Because of the way he installed his blog software, Matt has almost no content at the domain root. Except for one page, it's all in his "/blog/" directory. So I'd assume that when he set up his Webmaster Tools account he included the subdirectory in defining the "website".
You can set up sub directories separately in WMT, and that can help you with geographic targeting. I'd say getting different sitelinks for different subdirectories would be possible, but extremely rare. Each individual subdirectory would need to gain a high level of popularity for that to happen.
I have a site like his:
the domain root of my site has less contents but its blog, which is configured in its sub directory, has a lot of contents and backlinks.
In addition I have already set them up in WMT separately.
My domain root shows sitelinks but my blog doesn't.
I want my blog to display sitelinks when my name is searched like Matt Cutts.
That's why I asked you this question.
I know it is self-satisfaction.
It would be very rare for somebody to search my name.;)
Type in a very popular mainstream entertainment title and chances are that occasionally one of these sites will pop up with sitelinks displaying.
In most cases the choice of sitelinks is logical and appropriately leads to a popular page within that subdirectory. However, I recently saw one PR4 site where the sitelinks lead to other subdirectorys under the root, in which 7 out of 8 didn't serve the query and I was wondering if perhaps it was a glitch since this site has since lost them.
