With the growing adoption of smart speaker devices, and the evolution of related voice search tools, most businesses are now at least somewhat aware of the coming shift in search behavior. But you may not be aware of just how significant the voice search trend is set to be.

According to eMarketer, 35.6 million Americans used a voice-activated assistant device at least once a month in 2017, an increase of 128.9% YoY. comScore, meanwhile, has predicted that up to 50% of all searches will be voice originated by 2020. For those not paying attention, that's next year, a prediction that various other experts have supported. 

It still seems a long way off, it doesn't feel like voice is that close to becoming such a dominant search force. But clearly, usage is rising - and it's worth businesses considering how they can best align with that shift.

So how can you optimize your content and website for voice queries? That's what this new infographic from Headway Capital covers - looking at the various implications, the graphic outlines the key considerations you need to keep in mind to maximize your voice search potential.
