That's an analytics chart of the traffic sources of a little niche site of mine. That's a very bad example of a good mix. Analytics doesn't show social traffic as an actual source, it comes under referral. You know what happened to that little website?...
The traffic completely died, that's only just over 400 visitors for this month of October. Last month it was 5000 visitors… for a site about mattresses! You can guess what happened if you've been paying attention to the realm of SEO lately. A new Google Panda update was rolled out and it negatively impacted my site's rankings in a very dramatic way.
