5 Voice Search Optimization Strategies You Need to Know

Voice-enabled speakers like Google Home and Amazon Echo have become a significant part of consumers’ everyday lives. According to research from eMarketer, almost 75 million people in the United States will use smart speakers in 2019. And, nearly three-fourths of those users will use their smart speakers to conduct general searches. This rising usage makes voice search optimization an increasingly important effort for marketers.

By optimizing content for voice searches, brands can position themselves to show up in “position zero” (i.e., the only result in smart speaker searches). But smart speakers and voice search haven’t been around for long and brand marketers are still trying to figure out the best way to optimize their content.

Last year, Backlinko conducted a study to find the most important ranking factors for searches on the Google Home smart speaker. Here are five of the most critical findings from the study to help your brand amplify your voice search optimization efforts.

No. 1: Google Home favors pages with fast load times

This factor shouldn’t be too shocking since voice searchers are naturally going to value quick, accurate answers. According to Backlinko, the average voice search page loads in 4.6 seconds (roughly half the time as average webpages).

Remember, while mobile and desktop search results might list multiple results, smart speakers only provide one. This reality makes voice search optimization on smart speakers a zero-sum game.

Make sure to give your content a chance of reaching “position zero” by speeding up your webpages. Check out this post to learn how to identify page speed and other common SEO issues: How to Conduct a High-level SEO Audit.

No. 2: Google Home opts for more authoritative domains when delivering search results

Pages with higher domain scores (a metric for determining a webpage’s quality and authority) tend to perform much better in smart speaker searches. According to the study, the mean Ahrefs domain rating of a Google Home result is almost 77 percent.

No. 3: More than 70 percent of Google Home results were from HTTPS (secure) webpages

If you follow Google’s webmaster guidelines, this voice search optimization finding should make a lot of sense. In July 2018, Google announced it would start marking all non-HTTPS sites on their Chrome browser as “not secure.” This change is almost guaranteed to affect search rankings.

No. 4: Content that’s frequently mentioned or shared on social media tends to appear more in Google Home results

According to the study, an average voice search result has around 1,200 Facebook shares or 44 tweets. Backlinko was careful to note that Google does not include social signals in its ranking algorithm. Therefore, social media popularity is likely a case of correlation, not causation.

No. 5: Content that appears higher in desktop search results is more likely to appear in voice searches

A staggering 75 percent of voice search results from Google Home also rank in the top 3 positions in desktop searches. The most likely reason for this is that Google uses similar ranking factors to determine both voice search and desktop results.
