Google (and pretty much every other major search engine) uses hyperlinks to help determine reputation. Links are usually editorial votes given by choice, and link-based analysis has greatly improved the quality of web search.

We want people doing white hat search engine optimization (or even no search engine optimization at all) to be free to focus on creating amazing, compelling web sites. As always, we’ll keep our ears open for feedback on ways to iterate and improve our ranking algorithms toward that goal.

If you have an outstanding product, world class content, or something else that sets you apart, then you can step back and start thinking about how to promote it.

The objective is not to make your links appear natural the objective is that your links are natural.
