Using Google Ads is an effective way to drive your business online and boost conversions such as purchases and sign-ups. But mastering the art of measuring and optimizing those conversions according to your goals is essential.
Relying on traditional conversion tracking alone could cause you to miss critical opportunities to improve your performance and your return on investment (ROI). This method relies on cookies, which are limited by browsers and data protection regulations, and it ignores offline or cross-device conversions.
Google Ads offers a more sophisticated alternative: enhanced conversions. This feature lets you send first-party user information to Google, such as email addresses or phone numbers, when a conversion takes place on your site. This data, secured through hashing to protect user privacy, allows Google to accurately link conversions to your campaigns and bidding strategies.
In this article, we'll explore enhanced conversions: how they work, how to set them up on your site, and how they help optimize your Google Ads campaigns.
What are enhanced conversions in Google Ads?
Enhanced conversions in Google Ads is a powerful technology that allows advertisers to send first-party data, such as a user's email address or phone number, to Google after a conversion has taken place on their website. This data is hashed to ensure user privacy and is then used to tie specific conversions to the advertiser's ad campaigns, improving the effectiveness of bidding strategies.
Definition and importance for your campaigns
This feature lets you measure your conversions more accurately and implement more effective bidding. It works by supplementing your existing conversion tags with hashed first-party conversion data collected on your site, in a format that preserves user privacy.
The process uses a secure hashing algorithm, ensuring the data sent to Google remains protected. Enhanced conversions are vital for your campaigns because they allow you to:
- Improve conversion data quality, minimizing losses caused by cookie limitations and data protection regulations.
- Increase the volume of measured conversions, including those that happen offline or across multiple devices.
- Optimize your Smart Bidding strategies, thanks to more complete and accurate data for adjusting bids in real time.
- Ensure user privacy compliance by processing first-party data before sending it to Google and generating only privacy-safe conversion reports.
The types of conversions you can track
There are two main uses of enhanced conversions depending on your goals: for the web and for leads.
Enhanced conversions for web is ideal for advertisers who want to track sales and actions on a website, such as purchases, sign-ups, or downloads. It improves online conversion tracking by leveraging user-provided data at the moment of conversion.
Enhanced conversions for leads, on the other hand, is perfect for those who want to track conversions that happen off-site (e.g., by phone or email) from leads generated on the website. This mode improves the measurement of offline actions by a lead who was identified on the website, using information they provided when filling out a form or interacting with a call-to-action button.
Setting up enhanced conversions
To get the most out of enhanced conversions, three key steps are required: creating a conversion action in Google Ads, setting up your Google tag or Google Tag Manager, and adjusting tracking settings to match your goals. Here's how to do each one effectively.
Step 1: Create a Google Ads conversion action
A Google Ads conversion action represents a target event on your site, such as a sale, sign-up, or download. To create one, sign in to Google Ads, go to the Tools and settings tab, then to Conversions. Click + New conversion action and choose Website as the source. Fill in the details of your conversion action, including the name, category, value, conversion window, and attribution model. Finish by clicking Create and continue to get your tag code.
Step 2: Use Google Tag Manager or the Google tag for tracking
Google Tag Manager and the Google tag make it easy to install the conversion tracking code without modifying your site's source code. Google Tag Manager is ideal for managing multiple tags, while the Google tag is suited for quickly setting up a single tag.
For Google Tag Manager, create an account, add the container code to your site, and then configure conversion tracking. For the Google tag, copy and paste the provided code immediately after the opening tag or before the closing tag of your site.
Step 3: Advanced configuration and customization options
After installing the tracking code, customize it to suit your needs. Choose which first-party data to send to Google, such as emails, phone numbers, or customer IDs. Select your data collection method, such as JavaScript, CSS selectors, or automatic enhanced tracking. Enable or disable tracking for specific actions or domains.
For these adjustments, go to Google Ads, click Tools and settings, then Conversions. Select the conversion action you want to edit and click Edit settings to access the advanced options.
Best practices for conversion tracking optimization
To make sure conversion tracking is properly configured and delivering reliable data, it's crucial to follow certain best practices. This section provides tips on validating and troubleshooting configurations, understanding and analyzing conversion data using Google Analytics (GA4), and using this information to optimize your campaigns based on relevant KPIs (key performance indicators).
Understanding and interpreting your conversion data
Maximizing the value of your conversion data requires careful analysis and interpretation:
- Choose the right attribution model, such as last click, first click, linear, time decay, position-based, or data-driven, and compare campaign performance across these models.
- Set an appropriate conversion window for each action, reflecting the maximum time between an ad click and a conversion event, with options ranging from 1 to 90 days for web conversions and 1 to 60 days for offline conversions.
- Assign a status to each conversion action to indicate its importance to your business, choosing between "Include in conversions" or "Don't include in conversions", and adjust as needed.
Continuously optimizing your campaigns through conversion tracking
Enhanced conversions unlock features that help improve your campaigns:
- Smart Bidding strategies optimize your bids using machine learning, based on the likelihood of conversion. Choose from options such as target CPA, target ROAS, maximize conversions, or maximize conversion value.
- Remarketing audiences target users who have already interacted with your site or app, increasing the chances of conversion. Create lists based on specific conversion actions or use Google's predefined lists.
- Conversion path reports show the different touchpoints that led to a conversion, allowing you to identify the most effective keywords, ads, campaigns, devices, networks, and audiences.
By leveraging these features, you can optimize your Google Ads campaigns to hit your conversion goals and maximize your return on investment.
