you can have a high quality site with a very informative article... but you won't rank jack unless it has links. And if you have the wrong links, you'll get designated to the back pages where nobody goes anyway.
You have your signals a little screw balled here.
What is a
"very informative article"? Is that like a thousand other very informative articles that regurgitate the same facts everyone else has?
Matt Cutts did an interview 3 years ago on this very informative topic [

A high quality site would have only expert articles that tend to attract natural links. If your very informative articles cannot attract links from the greater public which have readerships that desire following expertise then you have a low quality website with pages no one wants to link to because they offer nothing new, just the same ordinary non-expert crap most other very informative websites have.
That obviously very difficult to compete with but that's the standard for top ranks.
Google continues to have a link obsession (because the signals tied to expertly crafted content) you can't easily fake expertise by adding non-expert articles and pretending those will do since they obviously won't attract natural links which forces you to fake your links.
Which get's authority sites in trouble. Link buyers are not the only people having problems link sellers (websites not normally considered as link sellers) [

I'm sure the average times all the sites that are waiting to recover (for what all of 7 months) is nothing compared to all the sites that unfairly ranked pushing sites that should have ranked lower... is equally in Googlers' minds.
