The popularity of voice search has been on a continuous rise for years and shows no signs of stopping. With the speed and ease of voice search, users are finding it to be the most convenient way to engage with search engines on their phones and voice-enabled devices, whether they are looking for the year “The Sound of Music” was released, finding directions to a new Vietnamese restaurant, searching for a recipe for Beef Wellington, or looking up answers for a math assignment.
You might be tempted to think that only youngsters are adopting this trend, but voice search is in fact more popular among retirees than school kids: users of all ages engage with voice search, but the largest demographic is the 65+ age group (75% of respondents use it more than once a day), closely followed by 18- to 21-year-olds (65%).
There are two basic types of voice searches that users complete:
- Voice searches on a device with a screen—usually a mobile phone—where the search query is made through voice, but the results are delivered visually like a text search.
- Voice searches made with a voice-enabled smart device, like an Amazon Echo or Google Home, where the result is spoken back to the user by the device’s AI assistant.
2020 was in fact the biggest year yet for smart speaker sales. We all must have been looking for someone to talk to while in quarantine because over 150 smart speakers were sold last year, including models from Amazon, Google, Baidu, Alibaba, and Apple.
As users become more comfortable with voice search on these voice-enabled devices, they are also more frequently utilizing voice search on devices that traditionally would operate with text input, such as mobile phones and even computers. As users incorporate voice-enabled devices into daily routines and information-gathering processes, search engine marketers are asking: how do I optimize for voice search and leverage this trend to grow my site?
The two types of searches mentioned above present two different opportunities for optimization and require related but unique strategies to capitalize on them.
How to optimize for all voice search
Before we get into the differences between types of voice search, there are some general principles to follow that will give rankings and visibility a boost across the board.
Conversational and Long-Tail Keywords
Voice search optimization, like any SEO, is about understanding user intent and matching that to a specific query. The formats of users’ queries, however, are different using voice search. Users engage with voice-enabled devices with natural language and longer sentences, largely due to the increased speed of speaking versus writing. Voice search queries are conversational and long-tail, such as “how do I build a garden with raised beds,” rather than “raised bed garden how-to,” and often begin with question words, such as “how,” “who,” “what,” “where,” or “why.”
It’s important to perform thorough research to identify the best long-tail keywords for your page and incorporate those into the title, headings, and content. Most keyword research tools include options to filter for long-tail or question keywords.
Page Speed and Core Web Vitals
As always, page speed and mobile-friendliness are key when trying to improve the ranking for any page, and especially when optimizing for voice search. Google has now completed its rollout of the Core Web Vitals update, so these “Page Experience” metrics are more important than ever to ensure solid rankings and a positive user experience.
Optimizing for Voice Searches on Devices with a Screen
Many voice searches are performed on mobile phones, computers, or other smart home devices with a screen, and strategies for voice search optimization have to keep the device in mind. In addition to the criteria listed above, optimization for voice search on devices with a screen have to take into account other factors that will influence user experience in the search engine results page.
