About Zocdoc

A technology list usually tells you how a website was built. Zocdoc tells you what the business behind the website does. The scheduling widget that Zocdoc publishes gets pasted into a page for one reason, which is that the owner of the page takes appointments from patients, so finding the script is closer to reading a trade directory than to reading a stack.

The company launched the service in 2007 as a consumer marketplace, and the marketplace is still where its own traffic goes. The embed is the other half of the model. A practice keeps its own domain and its own branding and rents the awkward part, the calendar that has to know which insurers are accepted, which providers are free on a Thursday afternoon and what happens when someone cancels. Written in JavaScript and delivered as a hosted, Proprietary component, the widget is a purchase made by an office manager rather than by a developer, and it is often the only third party code on an otherwise plain brochure site.

As of October 2026 we detect it on 835 sites. For a healthcare marketing team, a billing vendor or anyone selling into private practices, the resulting list is a filter for a particular kind of clinic, one that already books online, already pays for patient acquisition software and has already decided that its website should do work rather than sit there. Practices that would rather answer the phone do not appear at all.

Be careful about the direction of the error. Many practices link out to a marketplace profile instead of embedding anything, and an outbound link is not a fingerprint, so our count sits below the number of participating providers. Detection is also per site rather than per practice, since a group with several locations on one domain is counted once and a practice that gave each doctor a separate site is counted several times. And because the widget is a hosted script, a page can carry the embed long after the subscription lapsed.

What a downloadable list gives you that a per domain lookup cannot is the shape of the population. Checking one clinic tells you whether that clinic books online. Holding every domain that carries the embed lets you count practices by country code, by hosting provider and by whatever else runs on the page, and lets you watch the set move between releases, which is where the useful signal is, because a clinic that added the widget last quarter is a clinic that has just started spending money on its front door. No directory of these websites is published by the vendor, so the list has to be assembled from the outside.
