If a search engine let you differentiate and sort between content match vs pagerank match vs Adwords spend we might be able to mitigate the issue somewhat.
I'd not heard of the CMD+ENTER method before, so thanks for the heads up. Still not entirely sure what Firefox is submitting in that case. Will test.
I wasn't referring to this site in the parent comment, but to my freelance site. I'll put that site in my profile for 24 hours just in case anyone wants to take a look.
EDIT: Fixed, as noted in reply to nl's comments. A recent change led to a redirect line being mistakenly commented out.
I don't work in this area, but I'd say that 99% of the time I hear someone complaining about how Google is favoring sites that pay for advertising over them I find that they are making these incredibly basic errors.
For me, http://www.linguaquote.com/ gives a 404. It's only when I go to https://www.linguaquote.com/ that it works.
So I'm afraid it's not quite as simple as you make out in this case.
In other news, I've just pinpointed the missing line in the recently changed nginx config for Linguaquote; the http://www block had it's redirect commented out. Still, for this site in particular Google Webmaster tools is set up for the https version where no errors have been reported and SSL Labs gave an A+ for the stapling, PFS, heartbleed etc. etc. efforts I went to. I don't think this redirect was having an adverse effect on ranking, but I don't expect this site to hit the front page just yet - much more content to add before aiming for that.
I'd love to see an example (especially including the sites that should rank).
Will leave it there a bit longer in case you do come back to this thread as still genuinely interested in your opinion on the matter.
