I was hoping there would be a few people like yourself who have an interest in it and we can share what seems to work and what doesn't.
There are two website I am testing at the moment (with 2 more to be optimised in the next month or two) - one is reasonably well optimised on the site itself (i.e. title tags, H1 tags, meta description, keywords, etc) and would seem to need more content and one-way links to boost it further (although for many search terms it currently has a page 1 ranking).
Another is poorly optimised and I have just added around 200 one-way links to see if it goes from nowhere in Google to appearing somewhere.
