No one should be relying on Google for their income. And saying Google is killing your business shows some are. Traffic that changes because of an algorithm or bounces too fast is a waste of time. Build a business that appeals to customers, then build it so outside forces like FB, Twitter, Tumblr, Google and Adblockers can't harm it.
