Search Engine Land published a helpful post that answers some questions about the "future" of link building. Many attorneys (and some SEO teams) don't know (or forget) that good content is more important that links.
Some still fail to appreciate that Google algorithms are immensely smarter now than they were in the past. It is simply impossible (or will be soon) to "outsmart" the system with tricks or gimmicks. There is no unique way to game the process with linking schemes.
Instead, as the Google team has said all along, the best strategy is to create, good, interesting, well-written, useful content. Thats it. No games or gimmicks.
The improvement in Google's technology makes it more and more likely that their search ranking will reflect their will to encourage the addition of more useful content to the internet. It is wise to start now will more quality content that focuses on useful (as opposed to random linking schemes).
