A/B Testing with Google Optimise

Download as word doc with images

 

 

 

Need Google Analytics & Google Tag Manager set up

Also need to use Chrome and add the Google Optimise extension.

 

  • Log into / set up Google Optimize
  • You are only allowed 1 container for 1 account
  • The ID of the optimise container, has nothing to do with Google T.M, although it confusingly, has a GTM prefix
  • Link to GA in the menu on the right

 

  • Get the snippet code – you can add the extra line of code manually to your GA code (that you probably already have on the site)
    or you can do it through GTM

 

 

 

 

 

 

 

 

 

 

 

 

 

 

To add the code via GTM

Login to GTM

 

Click Add New Tag

 

Choose the Google optimise Tag type

 

Add Google Analytics ID (or choose the variable if you’ve set it up)

Then add the Optimise Container ID (see red arrow in previous screenshot)

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Name the tag

 

Click the box / icon below to choose a Trigger

 

Choose “All Pages” as the trigger* (assuming this is set up already)

 

*See this blog post for more info on setting up triggers – https://www.simoahava.com/analytics/trigger-guide-google-tag-manager/

 

 

 

The 2nd snippet of code prevents any ‘flickers’ of the default page (sometimes people might see both the A (for a moment) and then the B in the A/B test)

 

 

This code doesn’t work via GTM – as GTM loads code ‘asynchronously’ – which defeats the object

 

 

To make sure it loads first – ask a developer to add it to the <head> of the theme header

 

Or in WordPress – go to Appearance>Editor>Theme Header (header.php)

And paste the code just below the opening <head> tag

 

 

 

Back in Google Optimize

 

Click New Experiment button

 

Choose either A/B Test or Multivariate test

 

 

Now click +New Variant

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Give the variant a relevant name – e.g. “Green Button”

Click Add

 

Next click the arrow and “Go to Editor” (see arrow below) (need extension on Chrome)

 

When you click to Go to Enter – you should be taken to your website and have the ability to edit the HTML etc on there

 

 

 

 

Click Save on top right of editor screen to Save variation

 

Now enter Objectives – which relate to goals in Google Analytics

Save and Click Start
