Get started

Before you begin, make sure:

You have installed Google Tag Manager on your website
You have installed the GTM testing code snippet

1. Create Custom HTML Tag for your AB test

Create a new Custom HTML Tag with the name [Test ID]+[Test name] and paste the code snippet (copy from above) as HTML value of this tag.

2. Add a firing Trigger

Add a trigger to your new tag with type Some Pages and set url to matches with regex with the regex value* of your test page(s).

3. Schedule your Tag

If you have no set any start- or end date and time when creating the AB test code in the form above, you can use GTM's scheduling for tags.

4. Preview & Publish container

Preview your test before publishing your new GTM container and switch variations using the Lean CRO preview panel. Note, if you're using GTM scheduling, your tag will not fire until the scheduled date/time, even in GTM preview mode.

Go into Google Tag Manager Preview mode.
Browse to your test url with this url parameter:
http://www.yourdomain.com/your-test-page?preview_id=2

Publish your Google Tag Manager container and your test will go live on your scheduled date. Hooray!
