The Klar Attribution Browser Extension injects Klar's first-party attribution data directly into your Facebook, Google Ads, and TikTok ads manager — right where you need it when making budget decisions.
No more switching tabs. Your Klar attribution metrics appear directly in the campaign dashboard of each platform, so you can optimise with confidence.
If you have access to multiple Klar accounts, you can switch between them directly from the extension without re-authenticating.
Step 1: Install the extension
Click the link below and press Add to Chrome:
Step 2: Connect your Klar account
In Chrome, click the puzzle piece icon (Extensions) in the top-right corner of your browser
Find Klar Attribution and click it to open the extension
Log in with your Klar credentials to connect your account
Step 3: Add the required columns in your ad platform
The extension injects Klar attribution data into three specific column fields. You need to add Campaign ID, Ad Set ID, and Ad ID to your column selection in each ad platform for the data to appear.
Here's how to do it in each platform:
Facebook / Meta Ads Manager
Open your Meta Ads Manager
Click Columns → Customise Columns
Search for and add: Campaign ID, Ad Set ID, Ad ID
Save your column selection
Google Ads
Open Google Ads
Click the Columns icon → Modify columns
Search for and add: Campaign ID, Ad group ID, Ad ID
Apply the changes
TikTok Ads Manager
Open TikTok Ads Manager
Click Columns → Customise Columns
Search for and add: Campaign ID, Ad Group ID, Ad ID
Save your column selection
💡 Tip: Once the columns are added and saved, the extension will automatically inject your Klar attribution data every time you open the respective ads manager.
Step 4: Configuring the extension
Once installed, open the extension by clicking the puzzle icon in Chrome and selecting Klar Attribution. You'll see two configuration options:
Attribution Model
Choose which attribution model Klar uses to assign credit when injecting data into your ad platforms. Available models:
Model | Description |
First Touch | Full credit to the first touchpoint in the journey |
Last Touch | Full credit to the last touchpoint before conversion |
Data Driven | Dynamically reallocates credit based on Klar Pixel signals (time on site, user intent, channel type, order of channels, time lags) plus Zero-Party-Data such as discount codes and PPS answers |
Linear | Credit split equally across all touchpoints |
Any Click | Credit to any clicked touchpoint |
Unique | Deduplicates touchpoints before assigning credit |
U Shape | Emphasises first and last touch; distributes remainder linearly |
Time Decay | More recent touchpoints receive more credit |
