Siri started off a voice search trend all the way back in 2011, which means if you have not updated your site for voice SEO, then you could be missing out on organic traffic related to queries through voice assistants.
Originally the technology was not as streamlined or effective, but in today’s world, phones and smart home speakers are used to search for all kinds of information. (There were over 3 billion voice assistants in use as of 2019.)
As a result of this shift, older keyword strategies and short phrases simply cannot compare to the effect of long-tail keywords and the question-and-answer content needed for today’s SEO strategy. People are using voice search more than ever before, and thanks to AI technology, voice recognition and search accuracy are improving daily.
