Another way I sometimes analyze a site is to do the search [site:example.com keyword]. That number seems to have a good correlation with authority on a given topic. I'll bet it helps a site get multiple listings, too.
This is what I'm seeing too. The B2B site that I relaunched in September is now showing up to four top results per SERP for more and more of our important brand and product search strings. This site most definitely does NOT have a lot of quality inbound links (I'm working on that now) about all it has going for it is its authority in its niche (ok, and maybe some of the work I put into it getting it ready for relaunch)
Have a couple other clients with the same sort of thing, although not as clearly as the first. Wondering what it will do with some of my sites when the seasons roll around.
For me (and my clients) it's been a pretty positive change.
