The site was almost completely crawled every months since over a year. Just submitted the home page once, as they recommend. The page is actually a very rarely human visited help page, but with a good potential. This page now sits on 18th position for a single but uncompetive keyword and considered as an inbound link to the same site. OOps, forgot to mention ther is a direct hidden link to this page from the home page.
Motivation is key to education.
Interestingly enough, I spoke with a Google spokesperson about this very topic. One of my clients wanted to look into using the paid for google site search. What this means is that by checking your site search frequently, you will know when google tweaks their algo because your pages will shift.
