Integrating Google Analytics 4 (GA4)
The Google Analytics 4 integration allows you to import product performance data directly into your Lengow catalogue.
Once imported, this data becomes available as additional catalogue fields and can be reused across rules, segments, exclusions, and optimisations. This enables you to build more performance-driven strategies using real business signals from GA4.
⚠️ Before you start
Before configuring the integration, ensure you have:
- A valid Google Analytics 4 account.
- Access to a GA4 property.
- Product identifiers that match exactly between your Lengow catalogue and your GA4 events.
Step-by-Step configuration guide
Step 1: Open the Apps section
Navigate to the Apps section in the left-hand menu and search for "Google Analytics 4".
Step 2: Connect your Google account
Click the Sign in with Google button.
Authorize Lengow to access your Google Analytics account.
Once connected, a confirmation message will appear.
Step 3: Choose the catalogue to enrich
Click Choose a catalogue to select which catalogue will receive the Google Analytics data (additional dimensions and metrics).
⚠️ Important: A catalogue can only be linked to one Google Analytics configuration at a time.
Step 4: Name your source
Give your Google Analytics additional source a clear name (e.g., Google Analytics, GA4 France, GA4 Main Store). This name will help you easily identify the integration later in your catalogue settings.
Step 5: Select your GA4 account and property
From the dropdown menus, choose:
Google Analytics account: The Google account containing your analytics data.
Property (Web or App): The specific GA4 property from which data will be imported.
Step 6: Match products between Lengow and GA4
Select the common Product identifier used to link your Lengow catalogue products with your GA4 products (e.g., Product_ID, sku, item_id..).
⚠️ Critical Step: The selected identifier must exactly match the identifier sent in your GA4 tracking events. If they do not match, performance data cannot be associated with your products.
Step 7: Select Dimensions and Metrics
This is the core of your integration. Note that Google limits imports to up to 8 dimensions and up to 10 metrics.
1. Choose your Dimensions Dimensions are descriptive or textual data used to segment and analyze performance. Tick the boxes for the dimensions you want to import (e.g., Product name, Brand, Event name).
2. Choose your Metrics Metrics are numerical performance indicators that measure product engagement. Tick the boxes for the metrics you want to import (e.g., Product detail views, Products purchased, Product revenue).
Step 8: Define the data timeframe
Choose the time window used to aggregate your GA4 data (e.g., Last 7 days, Last 30 days, Last 90 days).
Recommendation: Shorter periods allow for highly reactive optimizations, while longer periods provide smoother, more stable performance trends.
Once you have selected your timeframe, click Save configuration.
What Happens Next?
Automatic Field Creation
Once the configuration is saved, Lengow automatically creates new fields in your catalogue corresponding to the dimensions and metrics you selected.
How to Use Imported Data
Your new GA4 fields become fully reusable across the Lengow platform. You can use them to create data-driven feed management strategies:
Rules: Increase visibility for products with high revenue.
Segments: Segment products with a low engagement rate.
Exclusions: Exclude products with zero sessions.
Optimisation: Prioritize products with high add-to-cart rates.
Monitoring Synchronization
You can monitor the integration from your dashboard, which displays the connected catalogue, imported fields, sync status, and the last synchronisation date.
A successful synchronisation confirms your catalogue is enriched and ready to use!
