Drupal Voice Search: How to Set Up Search Based on Voice Recognition on Your Drupal Site

by Adriana Cacoveanu on Mar 23 2020

Drupal voice search has gone from trend to standard these days. 

So, you can't help ask yourself: 

"How do I enable search based on voice recognition on my Drupal website?" 

And that's precisely the question that I'm about to answer in this blog post. 

That, along with all the other ones that must be "haunting" you: 

 

  • How does voice search impact my revenues? 
  • How do I optimize my website content for voice search queries? 
  • How do I set up a custom voice search engine on my Drupal site? 
  • Can I even build a voice-powered app with Drupal? How? 

     

1. How Does Voice Search Impact Your Traffic, Conversions, Revenues? 

“Voice Shopping Set to Jump to $40 Billion By 2022, Rising From $2 Billion Today“ (source: prnewswire.com)

How does making your Drupal website voice search-friendly translate into higher conversion rates? 

The logic is simple: 

 

  • it's more convenient for users to speak to the search bar than to type in their queries in order to find the needed products or services
  • by allowing them this convenience, you improve their experience on your website and that'll bubble up to your web traffic, conversions... revenues 

"Becoming voice-first is going to be the new mobile first" (DrupalCon Nashville 2018) 

In other words: 

 

  • understanding how search engines provide accurate answers to users' vocal queries
  • optimizing your content to the patterns that you will have identified 

     

… will have a huge impact on the user experience on your Drupal site.

And great user experience is what sets high ranking websites apart from... the rest. 

 

2. Here's How You Make Your Content Cater to Voice Search Queries 

Spoiler alert: I'll be pinpointing just the main techniques to apply for optimizing your content for voice search. 

If you feel like delving deeper into this topic, we have a full post focused solely on actionable tips for optimizing your website for voice search.

That being said, here's the list of essential voice search SEO techniques to implement:

 

2.1. Incorporate Short, Simple, Clear Answers Into Your Content

30 words at most, according to Backlinko's research.

 

2.2. Fine-Tune the FAQ Page on Your Drupal Site

This page alone plays a key role in your voice search optimization strategy. It's there that search engines often “extract” their answers from.

 

2.3. Use Natural Language When Writing Your Content

A user would speak to a search bar as he/she would ask a question to a person. Which is significantly different from him/her interacting with a text search box via a robotic keyword search entry.

 

2.4. Configuring Drupal for Voice Search: Optimize Your Content for Google's Featured Snippets

I'm not going to get into details here, but there are lots of highly valuable MOZ blog posts on this topic that I recommend you have a look at.

 

2.5. Center Your Drupal Voice Search Strategy Around Question Keywords

“How to...”, “What to...”, “Why use...”

 

2.6. Make Sure to Include (Really) Long-Tail Keywords Into Your Content 

5+ word keywords, I mean.

 

3. Set Up a Drupal Voice Search Engine in Just a Few Steps 

How do you create a search system based on voice on your Drupal website?

Here are the easy steps to creating a custom voice search engine with Expertrec: 

 

  • First of all, you need a google tag manager account, a Gmail id, access to your Drupal admin dashboard and a valid sitemap 

     
  • Set up an account on https://cse.expertrec.com??platform=cse using your Gmail ID

     
  • Enter your website's URL login to your Drupal admin panel and install google tag manager: https://www.drupal.org/project/google_tag

     
  • Enter your google tag manager ID and save the configuration

     
  • Access https://cse.expertrec.com/csedashboard/home/code and copy that code

     
  • Add the first part of the code in your control panel, using Google tag manager

     
  • Use the custom HTML option and configure the trigger to place it on all the web pages on your Drupal site where you want the voice search enabled

     
  • Go to Structure-> Block layout-> Header ->Place block-> Add custom block-> click on source and enter: <ci-search></ci-search> (opt for "full HTML"). It's this code that will display a search box in your website's header

     
  • Hit the Save button and finally, navigate to UI customization->features-> enable voice search 

     

And that's it: 9 simple steps to add voice search to your Drupal site. 

 

4. Building Your Own Voice App: Why Would You Want to Use Drupal? 

Now, let's say that you've optimized your Drupal website for voice search, improved your search ranking and given your traffic a major boost. 

And you've decided to go further and... build your first voice app, as well. 

Why would you use Drupal to build it? 

Here are some of the most solid reasons: 

 

  • Drupal provides you with a sophisticated user permissions and access control system
  • it allows you to restrict access to content
  • it provides you with fieldable content
  • it ships with a pre-built front-end Drupal
  • it enables you to put together complex content workflows
  • it provides multi-language support out of the box
  • it provides you with an API module 

     

Note: in the end, it's your use case, along with all the specific feature needs deriving from there, that should influence your final decision. 

But how would your Drupal voice app work, more precisely? 

Here's the whole "mechanism" in the back-end, summed up to 4 stages: 

 

  • the user talks to the voice assistant (Alexa, Siri, Cortana...)
  • the voice assistant talks to Drupal
  • Drupal provides an answer to the voice assistant
  • the voice assistant delivers the answer to the user 

     

Chatbot API is the module that makes communication between Drupal and the AI voice assistant possible. It integrates, out of the box, with Dialogue Flow and Alexa.

I won't go into detail on the basics of a voice-powered app and the fundamentals of a VUI design.

Yet, I recommend you watched the DrupalCon session on Powering an Alexa App with Drupal. It includes a handful of useful tips and actionable information on building a Drupal-powered voice search.

In this chapter, my sole intention was to outline those Drupal features and functionalities that make it the best candidate for a voice app. 

 

The END! 

I won't hide it: I'm curious whether you've already got your Drupal website voice-search friendly or not just yet. 

What strategies have you implemented so far to make your content more findable for vocal queries? 

Have you set up your own Drupal voice search engine?

Are there any obstacles that Drupal challenged you with? That made the whole optimization for voice search more complex than expected?

Is Drupal Good for eCommerce? 11 Excellent Reasons Why You’d Choose It over Another Platform

Is Drupal Good for eCommerce? 11 Excellent Reasons Why You’d Choose It over Another Platform

"... wanna run eCommerce on Drupal 8 but don't know if it's a good idea." But is Drupal good for eCommerce?  And, most of all: Is it better suited for your own online business needs and feature requirements than other eCommerce platforms out there? Some legitimate questions you're struggling with there… To give you a hand, here's a list of 11 excellent reasons why you'd lean towards Drupal for your next eCommerce project. Reason #1: You're in Full Control of the Source Code to Make Any Changes You Want In other words, you don't need to convince vendor first that the changes you need to make are beneficial for him/her. You're free to extend Drupal eCommerce platform's core functionality, to adapt, and extend its code till it meets your needs entirely.  … till it integrates perfectly into that specific software that you use. Which is not the case when you go for a commercial solution: you're not granted access to the core code for any custom software development work that you might need to make. Of course, this "reason" becomes a really strong selling point only if/when: you have non-standard business requirements it's a large, complex eCommerce website that you're building Reason #2: Your eStore Grows With Drupal  Drupal scales with your business... effectively. And by that I mean that it's designed to keep the resources and the time required to handle your online store's growth at a minimum. Being: flexible by nature (its open source nature) powered by the API-first initiative … the Drupal 8 eCommerce platform makes the best choice if "scalability" is on top of your list of requirements. Reason #3: You Get to Reach Out to Your Customers Across Multiple Channels  "Is Drupal good for eCommerce?" It becomes the perfect option for your own eCommerce website if you're planning to reach out to your customers across an entire network of sales channels. Let's say you have your main/central eCommerce website and you need to pull content from there and to distribute it across a whole ecosystem of channels — eCommerce apps, digital kiosks, conversational interfaces — and devices. Then, the API-first initiative allows you to tap into a headless commerce Drupal architecture and: use Drupal as a back-end content repository configure your content to fit all types of formats and reuse it whenever (and wherever) needed increase your outreach incorporate business automation into your development team's workflow: help them work smart and achieve more Reason #4: You Get to Deliver Content-Driven eCommerce Experiences With Drupal, you get the best of both worlds: an eCommerce platform (by integrating one of its specialized eCommerce modules into the content management system) a content platform And this is what makes it ideal for: tapping into the experience-led eCommerce model getting the most out of your content marketing efforts (think blog posts, effectively interconnected product pages, user guides, etc.) Reason #5: You're Free to Integrate Any Third-Party Service into Your Online Store From: marketing platforms to analytics services to payment gateways of your choice (there are 80+ payment options available with Drupal Commerce) to third-party add-ons that would automate your team's tasks and boost their productivity (while boosting online sales, as well) … Drupal &amp; its eCommerce component accommodates any type of integrations you need to make. Reason #6: "Is Drupal Good for eCommerce?" It Is for Delivering High-Speed eCommerce Experiences Just think… real-time shopping cart updates.  Or pretty much any action that your customers would need to carry out on your eCommerce site, then turbocharge it with top speed. A decoupled Drupal Commerce setup (add the JavaScript framework of your choice here) enables you to deliver such type of dynamic user experiences.  Reason #7: You Have No Limits to How Much You Can Extend Your Drupal 8 eCommerce Website Drupal Commerce can grow as much as your business needs. Whether you need to integrate: a whole network of third-party systems a whole lot of contributed modules an eCommerce Drupal distribution (a bundle of multiple modules) a Drupal eCommerce theme  … and extend your eCommerce store's functionality, there's no limit to what you can incorporate into your Drupal eCommerce website. Reason #9:  You Benefit from an Extremely Configurable eCommerce Solution "Whereas eCommerce solutions are often developed with an application mindset, highlighting what you can do with it out of the box, Drupal Commerce was developed with a framework mindset, focusing on what you can build with it." (Source: Drupal.org) Basically, you're free to customize every little piece of your Drupal 8 eCommerce site, till it: delivers that unique shopping experience you want it to meets all your ultra-personalized requirements: to trigger certain actions based on user input, to display multiple tax rates, to have an out-of-the-ordinary checkout flow, etc. Here, it's up to you and it depends on what you need to build: Are you looking for a cookie-cutter eCommerce solution, that would help you get a generic webshop up and running in no time? Or do you want unlimited customization freedom, that comes at the cost of…  investing more time in writing custom code? Reason #10: You're Free to Sell Both Physical and Digital Goods And that thanks to Drupal Commerce's flexibility: It provides you with the functionality you need to start selling your digital products — subscriptions, tickets, online courses, etc. — on your online store. A key aspect to consider when comparing the features of your best options in terms of eCommerce platforms in 2020. Reason #11: You Can Make the Most of the Granular and Differential Access to Content Drupal allows you to define different roles for your team members and to assign several levels of permission to each role. Not everyone would then be authorized to edit content, add products, manage orders, publish content, etc. This way you get to: set up a convenient hierarchy harden your online store's security  So, Is Drupal Good for eCommerce? Maybe a more appropriate question would be: "Is Drupal the right solution for my eCommerce business?"  It might be... And these 11 reasons mentioned here do become the best arguments for you to choose it over another platform (Ubercart, Prestashop, Shopify…) if: it's a growing or an already established eCommerce business that you run (otherwise, all that configuration and custom work might be an overkill for a small business) you have complex feature needs for your online store: you need to integrate it with coupon rules, several backend systems, and so on Do you fit the eCommerce business owner "profile"? For we do fit the profile of that Drupal eCommerce agency you're looking for, capable to tweak it till it fits your complex requirements to the slightest detail.

10 Best Headless CMS in 2020, That Cover Most of Your Requirements (Part 1)

10 Best Headless CMS in 2020, That Cover Most of Your Requirements (Part 1)

Overwhelmed with options? Are you building your first (e-commerce) headless CMS and you don't know what headless CMS platform to choose?  What are the best headless CMS in 2020, so you can at least narrow down your choices and start... somewhere? Which system matches most of your feature requirements? Here's a top 10: 1. But First: What Is a Headless CMS, More Precisely? Relax, I won't bore you with too many details — we already have an in-depth post on the differences between headless and traditional CMS. So, if we were to sum up the concept in just a few words, we could say that: A headless content management system is an architecture where content is separated from the presentation layer (the client-side front-end). Meaning that you get to create, store, and edit "raw" content (with no design or layout) in the backend and deliver it wherever needed —wearable, mobile app, website — via API. In short, what you get in a headless architecture is: a database to store your content in a dashboard for editing your content Source: Zesty.io As for the "head" that serves your content to the end-user : you're free to build your own front-end, from the ground up … and even multiple front-ends, if needed, that will all use calls from the API to retrieve and display content 2. … Then What's a Decoupled CMS? Headless CMS vs decoupled CMS: what's the difference? And why headless over decoupled? The role that the API plays… That's what makes the difference (and why you'd want to go for a headless approach): If, in a decoupled architecture, the API plays the role of an intermediary between back-end and front end, in a headless architecture the API can be used by any of the front-end portions for pulling data. In other words, a decoupled CMS does come with a built-in front-end delivery layer, that you can rely on, but a headless approach is an API-driven content repository. Which gives you more flexibility for delivering content to any type of display layer. … to multiple "heads". You're free to distribute it wherever it needs to get displayed. 3. Why Choose a Headless CMS? Top 9 Benefits Before I "divulge" the best headless CMS in 2020 to you, here's a shortlist of the key advantages of using a headless CMS software: you get to engage your customers with personalized content across an entire network of digital channels, at different stages in their journey you can deliver richer digital experience, tailored to each channel you gain platform independence you're free to choose your technology of choice you benefit from cross-platform support you get to manage your content from a central location and distribute it to multiple platforms/IoT-connected devices, in a universal format you're free to manage all your platforms from one interface your development team gets to choose the development framework of their choice, integrate new technologies and, overall… innovate you're free to redesign as often as you need to, without the dread of re-implementing your entire CMS from the ground up     4. … And When Should You Use It? 5 Best Use Cases  How do you know for sure that you need to adopt this approach? You know it because your scenario describes one of the following use cases for headless CMS: you're building a site using a technology you're familiar with you're building a website with a static site generator you're building a JS-based website or web app you're building a native mobile app you're building an e-commerce site and you know that the commerce platform you're using won't… cut the mustard as a CMS; or you need to enrich product info in your online store 5. What Are the Best Headless CMS in 2020? Top 10 "Which CMS should I use?" you wonder. "The one that meets most of your requirements…" So, you should start by pinning them down. What features are you looking for in a CMS? Maybe you need a system that should: be straightforward and easy to use for the marketers/non-technical people in your team be built on… Node be highly customizable and editable for your content team to be able to change overlay text, logo, background video/image be simple to set up integrate easily with Gatsby support multi-site setups not be tied up to (just) one specific database provide ease of content entry and rich-text support provide a granular permission system provide native support for content types What are the features that your project couldn't live without? Now, with that list of "mandatory" features at hand, just drill down through your top headless CMS options in 2020. Here they are: 5.1. Storyblok A purely headless CMS that ships with a visual editor, as well. Why would you go for Storyblok? What makes it one of the best headless CMS in 2020? it provides the experience of a page builder for all those non-technical users in your team: editors get to manage content via a more user-friendly interface it grants your developers easy access to the APIs they need 5.2. Prismic Its major selling point? It allows you to choose your own language, framework, technology… And these are the 3 good reasons to go with Prismic as your headless CMS: it allows you to model your content schema and to add your content you're free to choose whatever framework that meets your feature needs: React, Vue, Next, Nuxt, Node, Gatsby… you're free to choose either GraphQL or RESTful API to query content 5.3. Drupal 8 Headless CMS   Another great option is to exploit Drupal's headless capabilities and pair them with the JavaScript framework of your choice. Here are some of the best reasons why you'd use a Drupal 8 API-first architecture: Drupal's a mature and enterprise-level headless solution backed by a wide community, used by more than 1 million sites globally; you get to tap into its massive module collection and even create new custom ones to extend your website's functionality its JSON:API follows the JSON:API specification; developers in your team can start using the API even if they're not experts in working with Drupal you get to load your GraphQl schemas straight from your Drupal content repository; there's a specialized module for this: the GraphQL module you get to use all of  Drupal's famed features (granular access to content, processes, workflows, modules, etc.) right away; you get them out-of-the-box since the REST API is… rooted deep into Drupal 5.4. Strapi, One of the Best headless CMS for Gatsby. It's an open-source Node.js headless CMS, a "host it yourself" one, that allows you to build Node.js apps in… minutes. Why would you use it? because it generates available RESTful API or uses GraphQL shortly after installation, making data available via customizable API because it allows your developers to invest all their resources in writing reusable app logic (instead of having to use some of that time to build an infrastructure) because it's fully JavaScript because it supports plugins that extend the platform's functionality because it's open-source: you'll find the entire codebase on GitHub  5.5. Contentful  Looking for a platform-agnostic solution? A… content delivery network that would enable your development team to manage and distribute (and reuse) content to multiple channels? Then this is the API-driven headless CMS you're looking for. Here are 6 other reasons why you'd want to put Contentful on your shortlist: consistent APIs easy to set up you're free to create your own models easy to use: ships with a robust, non-technical, user-friendly UI you get to add custom plugins quick and easy you get to set your own schemas to get displayed the way you want them to, across different apps Good to know! There's even a Shopify extension available. What it does is connect your online store to your content, stored in Contentful. And if you'll need help with building, fine-tuning, and integrating your content hub, we're ready to tweak Contentful to your needs.  END of Part 1!
