It is always important to try different traffic sources. You would be amazed how the quality and interaction with your website and content can vary. Targeting different traffic sources will tend to mean you attract visitors from different user groups, with different needs and expectations.
Here is my advice. Take one piece of content, look at your target audiences and the goal you set yourself. Don’t just publish the content on your blog or your website. Play with different elements or parts of that content (eg Video, Twitter cards) and create different little snacks for different channels (snackable content) that you can test on various platforms (Social Media, email Newsletter, Video).  In this way, you can create a whole content campaign out of one single piece of content allowing you to analyse how visitors from different sources behave and fit into the buying cycle for instance.
By the same token it’s also important to play with and test content for new technologies and devices. The future of search will be very different, incorporating voice, visual search and virtual reality which are all on the rise.
