It's great to hear the strategic noindexing works as it was intended, at least that's the impression I get from all of MC's videos.
I my experience it does.
To expand a bit, one thing I've noticed is if I have a page that ranks for "widget" and another is more specific, if I noindex "the wrong page" they replace it with the "right page" that's "the next best choice" based on the factors, in the same position on the SERPs.
When I get the "right page" to replace the "wrong page" for a query and wait, usually the "right page" moves up in the rankings, which I believe is due to visitor behavior. I don't like to "let Google decide" if there could be a better page ranking for a term, because I believe visitor behavior is a factor (based on my experience) and if I can get people to the "right page" for the query more often, then it's a better result for not only me, but the visitor and Google.
I guess what I try to do is get things to "mesh" together to the point where if Google has determined the "wrong page" should rank, I'll pull it out, leave the "right page" in and let the algo "do it's thing" as visitors respond to finding what they were looking for easily.
* I should note I'm a bit "contrary to many", because I aim for a high bounce rate since to me, as long as the query and info on the page "mesh", then the search ends it says "good result". IOW: Google's visitor searched. They clicked on the page I "tailored" for the results. The visitor found the info they were looking for on on the page. The search ended. I don't see how that's bad for Google, the visitor or my site and I've had a page with +90% bounce rate that was in the top 3 (usually only behind the EMD I wrote the info on) for years before I let the site go to back up the "thought" I have about a high bounce rate not necessarily being a bad thing.
ADDED: As far as bounce rate goes, one site I've been working on regularly averages +75% and it's getting closer to 80% on average. Traffic is finally starting to consistently climb and bounce rate has been increasing at the same time. I know it shows red in Analytics and "everyone" says if it's too high that's bad so they try to manipulate the number, but w/e, more traffic (not "seeing green" in Analytics or doing what "everyone" says) is what I'm after.
