Very difficult to find a tutorial on this using the new Adwords interface.
To begin with
Remarketing in Google Analytics
Enable Remarketing in Google Analytics
Go to the Admin part of Google Analytics
In the Property (middle) column click – Tracking info – Data Collection:
Turn on Remarketing ON and Advertising Reporting Features ON
– Next link to Adwords:
Still in Admin and in the same column
Go to Audience definitions – Audiences:
You’ll now be prompted to create a new campaign in Adwords:
Apply Remarketing Tag in Google Tag Manager
If you haven’t already you will have to add the remarketing tag/code to your website:
Click – Audiences – in the sidebar inside Adwords
Select the remarketing list that you just set up straight from Google Analytics
Then click Audience Sources:
Scroll down and click “Setup Instructions and tag code”
Scroll down and click Use Tag Manager – then copy the code that appears in the box:
Now over to Google Tag Manager
Create a variable first:
Click “NEW” under User Defined Variables
name it – “GAconversionID”
Choose “Constant” and give it the value of the ID from Google Adwords (the code we copied)
Create a Tag:
Name it “Adwords Remarketing Tag”
Under Tag configuration – Choose Google Adwords Remarketing
Conversion ID – use the variable that you just created – GAconversionID
Fire it on all pages (unless you only want it to fire on a specific page)
Publish the changes.
Use the Google Chrome Tag Assistant extension to check the remarketing tag is live on your site.
Note – if you use an Adblocker, you can get an error message here.
