Okay, I’ll take a turn. It’s too soon for me to attribute any engagement differences yet, but I absolutely agree about the no heavy coding part. My website was built from scratch by me. It has interactive forms with both client-side & server-side validation, progress bars using CSS and JavaScript, etc. Despite this, I find myself actually preferring Elfsight widgets in many cases. They work without any troubleshooting, are highly customizable, and in the rare event I need support, they are there. We specialize in accessibility and Section 508, and I have found the widgets here to either already meet those requirements or are made compliant upon request — see my thread regarding Social Share Buttons… not only was it resolved, but it was fixed globally for everyone’s benefit!
In the design/development business, time is money, and Elfsight is money well spent.
