Since Google's big changes in 2012 (Panda, Penguin) it's become fairly clear to many people that relying on Google as a source of traffic is destined to be painful. The many people building scammy AdSense sites up to 2008 already knew this when their earnings were decimated in that year by Google's algorithm changes.
So, much better to have a strategy where you rely on Google only as a source of supplementary traffic, not your main traffic.
For most people, probably, the best approach to this is to create really excellent content in a niche that you enjoy (so it's not boring). It needs to be so good that when people come there they will be happy to share it with their friends, followers, et cetera. Then if you get active in the relevant forums and questions and answers sites – which should not be a pain if it's a topic you enjoy – then people will follow the links in your natural posts, and in your sick, and the trickles of traffic you get will mount up to a steady stream.
This is a nice, solid strategy which doesn't depend on Google.
