You can see this phenomonon for our very forum here by searching on the keyword "webmasterworld".
For background, people can see this thread from last year:
Extended site description - what makes the extra sections happen? [webmasterworld.com]
This phenomenon first showed up late in the Summer of 2005, but when a site did get such a listing, then a second listing never was displayed (after all, 5 links in one SERP was already pretty good).
On one hand an indented second can give an appearance of importance, maybe giving the impression that G thinks a site is more relevant and thus attracting a few extra clicks.
But the non-indented second could catch surfers who were about to pass on the 1st listing.
Now which of those two choices would be more beneficial to a webmaster?
Previously, when you searched the Google "ie" interface [google.com] that gives you 100 title-only results, sites that had gotten the multiple listings on Google.com ended up not getting multiple listings on this interface, which seemed unfair.
Now that's been corrected, but along with the correction there's an extra listing on Google.com. I can see where Google might eventually decide to change that.
Take a look at this search for webmasterworld [google.com] on Google.com, and the same search [google.com] on the "ie" interface, and you'll see that the second unindented listing is the same on both.
The search on the particular word or phrase will show my site at the #1 result plus an indented result right under it.
Does this mean that my site is an "authority" or "hub" as talked about in the other threads regarding these extra listings?
By the way, can someone define just what an authority site is? I see the term tossed around quite a bit but not clear on exactly what it means.
PLUS, like with webmasterworld, "[ More results from www.webmasterworld.com ]" after the first result AND after the second result!
Message to the 'plex, this is a wee bit overkill...
I've also noticed that when I'm in Japan and doing a search on regular google.com (not .jp) it has a compound "shell" listing, where the structure of the compound listing is in place, but the additional urls are not present --only four "-" as place holders with white space underneath.
I'm not complaining, though...
Also Sara,
"Got that too on one of my sites but the weird thing is the authority is not my index page anymore."
Keep watching as it will rotate links during every data refresh. I have watched that happen over time.
