Hi there,
OK …the most useful feature of your favorite Elfsight widget.. 
I’d like to look at this from a different perspective. 
A widget that I can use for my purposes and that helps me achieve conversions is definitely my favorite.
However, the most useful feature(s) I value most are custom CSS/JS and the code editor. It’s only thanks to the very well-structured CSS classes that it’s possible to customize the layout/template specifications almost without limitations to match your own design. 
As a YouTuber, I love the YouTube gallery widget! It allows me to share my videos (without paying for video hosting) on my landing pages so people can stay on my site vs. leave to YouTube. I am saving money and making money!
My favourite Elfsight widget is the Google Reviews widget.
As a small local service business, trust is everything. Most customers visit my website to decide whether to call or move on to the next company, so being able to display my latest Google reviews directly on my site has been incredibly valuable.
The most useful feature for me is the automatic syncing of new reviews. I don’t have to manually update anything — every new 5-star review appears on my website automatically, which keeps the site looking active and up to date at all times. This saves time and makes sure potential customers always see fresh feedback from real clients.
It’s also helped increase enquiries because visitors can instantly see social proof without leaving the page. That extra trust makes a big difference for local businesses competing online.
Overall, it’s simple, professional, and delivers real results.

The Google Ads review widget that auto-populates on our website has become one of the most valuable tools in our marketing and customer experience strategy—and without a doubt, it’s my favorite feature.
As a company that takes immense pride in maintaining a 5-star Google rating, this widget allows us to showcase that credibility in a dynamic and authentic way. Rather than simply telling potential customers about our reputation, it allows them to see real, unfiltered feedback directly from the homeowners and business owners we’ve had the privilege to serve.
What makes this especially powerful is the convenience and transparency it provides. Visitors to our website can instantly view genuine customer experiences, detailed reviews, and even project photos—all in one centralized location without needing to leave our site. This not only builds trust but also keeps potential customers engaged longer, giving them the confidence they need to move forward with us.
In today’s market, where customers are more informed and cautious than ever, social proof is everything. This widget bridges the gap between interest and action by reinforcing our reputation in real time. It validates the quality of our work, highlights our consistency, and demonstrates the level of care we bring to every project.
Ultimately, it transforms our website from a simple informational platform into a powerful trust-building tool. It allows our satisfied customers to speak on our behalf—and there is no stronger endorsement than that.
The most useful feature is the AI chatbot’s ability to help customers instantly with the things they need most—store locations, hours, product information, availability, fitment questions, installation info, and general support. It improves the experience for all customers by giving fast answers 24/7, guiding them to the right products, and helping them find the nearest store or next step without waiting on a person. It also frees up staff time by handling common questions automatically, while multilingual support makes that same help available to even more customers in the language they’re most comfortable using.
I like the flexibility and customization options in the Music/Playlist widget. It allows me to present a clean interface to my clients that is visually simpatico with my site design. Well done us!
I like the widget that is adding my LinkedIn posts as articles on my Blog section of my website. It saves me a lot of time and gets me more visibility!
Love it. I need tools that are both powerful and intuitive. I’ve integrated these widgets for many of my clients, and the Calculator is hands down the standout feature. The developer team really nailed it—it’s the most flexible and precise calculator I’ve found for complex client requirements.
These widgets make my workflow very simple, and all the features I need are available. It significantly boosts conversions by giving users instant, eye-catching, transparent results. It’s rare to find a tool that balances profound customization with such ease of use, making it an essential part of my digital toolkit at Web Specialist 360.
Additionally, their support services are wonderful. Quick response, and they find a way to help you get the result you need.
If social proof is the heartbeat of a digital business, then Elfsight’s Google Reviews widget is the stethoscope that lets everyone hear it.
My favorite feature is the ability to transform raw, messy data into a curated “Wall of Love.” While Google provides the feedback and Squarespace provides the canvas, Elfsight provides the soul. The AI synopsis is a total stroke of genius! It’s like having a brilliant, tiny assistant summarize your best qualities for every visitor before they even start scrolling.
I’m obsessed with the level of control it gives me. I can handpick which stories to highlight, ensuring that the novelty stays fresh as people move through the site while maintaining a high-frequency signal of trust. It bridges a massive gap that neither Google nor Squarespace seems interested in filling: the gap between having a reputation and actually showcasing it with style.
It’s beautiful, it’s effortless, and honestly, it’s the “trust engine” I didn’t know my website was missing. I’m genuinely grateful to Elfsight for making social proof look this good.
for me - the best feature is once created - any changes needed and created on the elfsight widget are quickly deployed over the whole website - easy - for example - each of our products has a banner widget embeded in the product page - with 700+ products - one simple change to the widget = 700 instant changes & everything up to date and perfect
For me, the most useful feature of my favorite Elfsight widget — the Instagram Feed — is its simplicity combined with powerful customization options.
It’s incredibly easy to set up and integrate into a website without any technical complexity, which saves a lot of time. At the same time, the widget offers a wide range of settings, allowing me to perfectly match the design to the website’s style — from layout and spacing to hover effects and content display.
Another big advantage is how reliably it works and stays up to date automatically. Once connected, it continuously pulls fresh content from Instagram, keeping the website dynamic and visually engaging without any extra effort.
Overall, it’s the perfect balance between ease of use, flexibility, and real value for both website owners and visitors.
For me, the Social Media Icons are the best widget.
I use these on my websites to draw visitors attention to my social media suites. This has already given me quite a few followers. 
Para mí el mejor widget es el de las reseñas de google. Atrae muchos visitantes a mi negocio y genera confianza.
For me, the best widget is the Google reviews one. It attracts a lot of visitors to my business and builds trust.
Without a doubt, the most useful feature is the seemingly endless customization capability — not for a particular widget, but all of them.
Case in point, I was recently attempting to add a Contact Feedback popup to an existing hand-coded contact form. After the usual modifying the text to my liking and configuring the send-email credentials, I discovered several things.
My point is that this customizing capability is not limited to a particular widget or template. It may take a little experimentation to get it just right, but typing “Ctrl Shift-C” and then hovering over the element in question will quickly reveal the CSS class that needs modifying, and then it’s just a matter of adding the appropriate code. If you are not familiar with CSS syntax, bookmark this page, it is a near-complete index of all CSS options. Is all this worth the effort? The number of incoming emails generated from the Feedback popup, and the increased time-on-site and resulting conversions from it and other widgets say YES.
The Google review widget with AI has been a huge selling point in my business. It helps capture folks with substantial Google reputation but little web presence. We install it on all of our sites as standard practice.
The Accessibility Assistant is my favorite. With the large number of settings that are included in the widget, it makes accessibility a very welcome and important addition to my website. Along with the large number of great accessibility settings, the Site Accessibility Score is a great touch to add another level of professionalism and authority to my agency site.
As a web designer/developer, this is a must have on all of my sites, and the customization and installation were quick and easy, compared to others I have tried that were sometimes too involved or too gaudy. This is simple yet has all it needs for my site visitors, and looks great on all of my sites.
I love the Background Music widget for my hobby (photography) website. This can be said for all Elfsight widgets, but the team behind knows what we webmasters want. Their widgets have all the features we think are good to have. In addition, I love them letting us customise the CSS so that I can control every bit of the design and styling exactly the way I want!
The YouTube Gallery’s Source Groups has got to be my current favorite feature and app!! My historical society client uses this app to organize their playlists on their website. Multiple contributors add content on the society’s YouTube channel, but as long as it’s plopped onto an existing playlist, it syncs automatically onto the society’s website page. Nothing that I, as the web master, need to do. App’s doing its job! 
I’ve been using the Сalendar widget for over a year… but I’ve only recently realized one thing. This widget + my labors = helps people organize their leisure time in our city.
Yes, my site is getting more visitors yet. But in fact, this is not so important against the background of the fact that we are doing a useful thing for people
