Google is getting even tougher on sites that abuse links, says report

Not long ago, my site's search traffic jumped by about 120%, I hadn't posted anything new or done much SEO type stuff so I assumed it was because of a Google algorithm change.

As a site, we've never done link building or any type of black hat tricks to grow our site, and it seems like Google is rewarding that. So personally I applaud any effort that rewards quality content over SEO tricks.
