How to add Age Verification to a Concrete CMS site

Embed Age Verification on Concrete CMS

01

Create a Age Verification extension for Concrete CMS on Common Ninja

First, create a Concrete CMS Age Verification extension on Common Ninja. On the extensions catalog, find the Age Verification and enter the Editor.

02

Save the Age Verification extension

When you're done creating the Age Verification extension, click on the Save Changes button at the right top corner of the editor. If you don't have an account on Common Ninja, you'll have to register first.

03

Copy the Age Verification Embed Code

When you're ready to add the Age Verification extension to your Concrete CMS site, click the Add To Website button at the top bar of the Editor. On the window that opens, click the Copy Icon to copy the extension embed code. In the next steps, you will paste this code into your Concrete CMS site.

04

Paste the code to your Concrete CMS website’s HTML field.

Next, go to your Concrete CMS site editor and find the HTML field. It is most likely in the form of an HTML/Code widget or module which you can find on the Concrete CMS’s editor. Add it to your page, and paste the Age Verification Embed Code you’ve copied before to the HTML field. Save and update, and that’s it, you should have Common Ninja’s Age Verification extension on your Concrete CMS site.

05

Alternative Method 1: Through the HTML option in the text’s editing area.

If you can't find the HTML/Code widget or module, there's another way to put Common Ninja’s Age Verification extension on your Concrete CMS extension. You can just add the code to a special HTML section in the text editor.

06

Alternative Method 2: Add it directly to your Concrete CMS site’s HTML code.

If you're having trouble finding a widget or a special part in your text editor where you can add the Embed Code, you can try a different way to add the Age Verification extension to your Concrete CMS site. You can do this by putting it straight into your Concrete CMS site's HTML code.

Why Use This Widget

Use the Age Verification widget when access to your content or products requires legal age confirmation. It prevents underage visitors from entering restricted areas and protects your business from compliance risks. This is essential for alcohol, vaping, gambling, adult content, and certain medical or regulated products. The popup establishes clear responsibility by asking users to confirm their age before proceeding. It can also reinforce trust by showing that your brand takes regulations seriously. With a simple, focused interaction, you avoid complex gatekeeping systems while still meeting legal expectations. Placing age verification at entry keeps the rest of the site clean and ensures that only appropriate audiences continue.
