Voice search is growing in importance for SEO. While millions use Google voice search, many are unaware of the technical implications. Voice technology can now recognize queries with up to 90% accuracy. Websites need to be optimized for voice and mobile searches, focusing on phrases and conversational content. By 2020, 30% of browsing may be without screens, and by 2050 half of searches could be by voice. Proper optimization includes considering how people naturally speak queries and prioritizing frequently asked questions and featured snippets.
