38 Powerful SEO Tools for Voice Search Optimization

SEO tools for voice search optimization

In the digital age, there is no such thing as too much change. In fact, change is perhaps one of the very few constant things you can expect in technology. One of the more recent developments that search optimization has seen—and evidently must adapt to—in the last few years is voice recognition. It’s evolved so much since the emergence of Apple’s Siri that it’s become embedded into today’s culture; now allowing for instant commands such as voice search.

Back in 2016, Google claimed that 20% of mobile queries will be made through voice search. Their survey last year found that 72% of people with voice-activated speakers use it in their everyday lives. Not only does the considerably new technology make it much easier to multitask, but the development also takes convenience up a notch with faster actions and data retrieval—you don’t spend time reaching for a device, opening it, and keying in your needed task. On top of that, people also use voice search to find brand details like promos, tips, and events. This adoption now provides a new opportunity for digital marketers to up the game in content optimization.

Here comes the new challenge: optimizing for voice search. It’s a different game when you factor in things like understanding speech, mapping out a user’s journey, providing clear-cut keywords ready for one-answer results, and ultimately fine-tuning content to work with the likes of Siri, Alexa, and Google Assistant. Add this to the fact that voice search is more commonly used on mobile devices; your website should be mobile friendly too.

The answer to the new tech, therefore, lies in the tools you use. Not only will they help make optimizing a faster, more efficient process, you’ll also be able to hit all the sweet spots you simply can’t hit with the regular SEO protocol.

There are tons of handy SEO tools out there and finding the right ones may be challenging. It might seem tempting to invest in premium tools considering they offer you the state of the art features, but before you do that weigh your options first. Ask yourself some of these questions:

  • Does the tool provide features and actionable data you need?
  • How does this paid tool fit into your budget?
  • Is this identified free alternative something other marketers already trust?
  • Is there another alternative that could provide you the same if not better results?

Below is a list of 39 tools that provide powerful SEO services for voice searches. Take a moment to look through each of them and choose what works best for you.

Voice Search Keyword Tools

The most jarring difference between typing a query and saying it out loud is the fact that there’s less time to think about phrasing.

What colloquial terms might a person say instead of formal ones? Is the result pulled by the search engine within context? These tools can help:

When it comes to addressing this new way of sending through queries, at its heart, voice search is the same as search has always been. A user simply wants answers. The main difference is the more personal aspect of how it’s done.

Because voice search speaks directly to the search engine, there’s less concern over the brevity to cut time and effort in typing and more room to provide longer and more specific searches—not to mention the rising frequency of natural language terms. Location importance has also equally grown in value with a much larger volume of users now looking for products and services in a “near me” mindset.

In response to the new way to search is a new way to find answers. Google’s already started incorporating instant answers in results for voice searches. Thus, you need to consider these three important things when optimizing: colloquial terms used, user thought processes, and the platform by which these answers are accessed.
