When setting up conversion tracking for a “Thank You” page in Google Ads, you have several technical methods to choose from. Each method has its own advantages based on your tech stack, analytics setup, and marketing goals. Here are the primary ways:
1. Direct Tag Installation (Google Ads Tag)
How It Works:
- You manually place the Global Site Tag (
gtag.js) on every page of your website. - You add the Event Snippet specifically to the “Thank You” page.
When to Use:
- When you don’t have Google Tag Manager or Google Analytics implemented.
- Simple websites with static “Thank You” pages.
Pros:
- Direct and straightforward.
- Minimal dependencies on other tools.
Cons:
- Requires manual code insertion on the website.
- Harder to manage at scale.
2. Via Google Tag Manager (GTM)
How It Works:
- Add the Google Ads Conversion Tracking Tag in GTM.
- Set up a Trigger for the “Thank You” page (e.g., Page URL contains thank-you).
- Publish the container in GTM.
When to Use:
- When using GTM to manage all your website tags (recommended for larger sites).
- For dynamic websites where the “Thank You” page URL might change.
Pros:
- Centralized tag management.
- Easier to update and maintain without touching website code.
- Enhanced flexibility with triggers and variables.
Cons:
- Requires familiarity with GTM.
- Additional layer of management.
3. Via Google Analytics (GA4 or Universal Analytics)
How It Works:
- Create a Goal (Universal Analytics) or Conversion Event (GA4):
- Set the goal/event to trigger when a user visits the “Thank You” page.
- The condition can be a specific Page URL or a Custom Event.
- Link Google Analytics to Google Ads:
- Import the conversion from Analytics to Google Ads.
When to Use:
- When already using Google Analytics to track website activity.
- Ideal if you want to analyze conversion data alongside other website metrics.
Pros:
- Provides deeper insights by combining conversion data with other analytics.
- Allows advanced reporting and audience segmentation.
Cons:
- Slightly delayed data import into Google Ads.
- More complex setup, especially with GA4.
4. Using Enhanced Conversions (Advanced)
How It Works:
- Sends hashed first-party customer data (e.g., email, phone) to Google Ads when a conversion occurs.
- Enhances conversion tracking accuracy, especially for eCommerce and lead generation.
When to Use:
- When privacy regulations or tracking restrictions (like ad blockers) affect standard tracking.
- For improved measurement in a cookieless environment.
Pros:
- Improves conversion tracking accuracy.
- Helps recover lost data due to browser privacy changes.
Cons:
- Requires some development effort to send hashed data.
- Needs compliance with privacy policies.
5. Using Third-Party Analytics and Importing Conversions
How It Works:
- If using tools like HubSpot, Salesforce, or CRM systems, you can track conversions there.
- Import offline conversion data into Google Ads manually or via an API.
When to Use:
- When most conversions are offline (e.g., phone sales, in-store purchases).
- When you need to close the loop between online ads and offline sales.
Pros:
- Connects online ad clicks to offline conversions.
- Ideal for businesses with a hybrid sales process.
Cons:
- Manual process or requires API integration.
- Not real-time.
6. Using Conversion Tracking via a CMS Plugin
How It Works:
- Content Management Systems (CMS) like WordPress, Shopify, or Magento offer plugins for Google Ads.
- Configure the conversion tracking in the plugin’s settings, and it automatically adds the necessary tags.
When to Use:
- When using popular CMS platforms and want a low-code solution.
- If you are not comfortable with code or GTM.
Pros:
- Quick and easy setup.
- Reduces the risk of implementation errors.
Cons:
- Limited customization.
- Relies on the plugin’s compatibility with Google Ads updates.
7. Via Server-Side Tagging (Advanced)
How It Works:
- Instead of relying on browser-based tags, conversion data is sent to a server-side container before forwarding to Google Ads.
- Helps in scenarios with ad blockers or privacy restrictions.
When to Use:
- When tracking accuracy is critical, and client-side tracking is not enough.
- For more control over data collection and transmission.
Pros:
- Improved data accuracy.
- Bypasses browser limitations and privacy controls.
Cons:
- Requires technical knowledge of server-side tracking.
- Higher implementation complexity and cost.
