Sometimes there might be a lot of similar links on your websites that you’d like to track as a “Click” event and see reported in Google Analytics. Examples of these are clicks on your Social Media buttons, clicks on your contact forms, or any group of similar link clicks. However, if you have a lot of buttons under one category and have to create tags for each of those events, it will get tedious creating tags one by one. We’d like to show you how to save time by using Google Tag Manager’s (or GTM) Lookup Table and RegEx Table variables.

Pre-requisite before starting

All you need to do is ensure that GTM is properly installed on your websites! Then we’ll begin by creating variables, triggers, and tags. You can follow the steps outlined below.

Create variables – Lookup Table

A Lookup Table is a variable that will allow you to pair values from one variable with your desired value. So we can decide which link clicks to track and which value to return here.

1. Click on Variables

2. Click on New

3. Click on Variable Configuration

4. Click on Lookup Table

5. Select Choose Built-In Variable from Input Variable

6. Click on Click URL

This built-in variable, Click URL, will display the URL of the page where the button was clicked. This is where we indicate which link click to create as an event.

7. Click on + Add Row

8. Type your URL of any link clicks you’d like to track into input

9. Type “Social Click – Facebook” into Output

Here, I like to set my naming convention by categorizing and destination which the separator will be a dash symbol (-). For example, I name click to my Facebook page as “Social Click – Facebook.” The category is “Social Click” and the destination is “Facebook”

10. Click on + Add Row

If you have several link clicks to other websites, you can fill in more by clicking Add Row

11. Name your variables and click “Save” – Here I name it as “GA – Lookup Table”

Create variables – RegEx Table

In GTM, a RegEx Table is used to determine whether or not an input pattern matches and, if so, to return the corresponding output value.

1. Click on New

2. Click on Variable Configuration

3. Click on RegEx Table

4. Click on {{Click URL}} from Input Variable

5. Click on + Add Row

6. Paste “(.*?) – (.*)” into input

This is a regular expression that contains 2 capturing group which are (1) 1st capturing group (.*?) means to match any character until the next delimiter and (2) 2nd capturing group (.*) means to match any character until the end of string, this will ignore the next delimiter. For a dash (-) matches the character (-) literally.

7. Type “$1”

If you remember from creating Lookup Table, we have defined the naming convention with dash (-) separator. $1 here is equivalent to the text before the separator so this variable will return any value before the dash

8. Name the variable – Here I name it as “GA – Category”

9. Click on Save

10. Again, click on New to create RegEx Table for label

11. Click on Variable Configuration

12. Click on RegEx Table

13. Click on {{Click URL}} from Input Variable

14. Click on + Add Row

15. Paste “(.*?) – (.*)” into input

16. Type “$2”

$2 here is equivalent to the text after the separator so this variable will return any value after the dash

17. Name the variable – Here I name it as “GA – Label”

18. Click on Save

Create Triggers

1. Click on Triggers

2. Click on New

3. Click on Trigger Configuration

4. Click on Just Links

5. Click on This trigger fires on Some Link Clicks

6. Select GA – Lookup Table

7. Type “undefined” – The operator here should be “does not equal”

This means that any link clicks happen their {{Click URL}} are in the Lookup Table will be fired

8. Name the Trigger – Here I name it as Trigger – Link Click

9. Click on Save

Create Tags

1. You need to create tag to send link click event to GA by selecting as following:

• 1. Tag Type: Google Analytics: Universal Analytics
  2. Track Type: Event
  3. Category: Select from variable {{GA – Category}}
  4. Action: Click (you can define whatever you’d like here)
  5. Label: Select from variable {{GA – Label}}

2. This tag need to be fired on “Trigger – Link Click” so choose this as a trigger of this tag

3. Name your tag and click “Save” – Here I name it as “GA – Link Click”

Once you have done your set up, you will be able to see your event on Google Analytics under event report!
