I've worked with good content/SEO teams. Generally, they try to make interesting content, then they hire folks offshore to promote it. It's a low hit rate, but it works over time.

Another "technique" is to crawl sites that link out to 404s, or outdated guides. Especially if it's a high value site. Then email them and suggest their users might prefer <insert better widget/site/etc that you own here>.
