How to Find Conversion Rate in Google Analytics

Pinpointing your conversion rate in Google Analytics 4 can feel a bit confusing, especially if you're used to the old Universal Analytics. GA4 handles conversions differently, but once you know where to look and what to set up, you'll be able to track this vital metric with confidence. This guide will walk you through setting up your conversions in GA4 and finding your conversion rate across different reports.

What Exactly Is a "Conversion" in Google Analytics 4?

First, let's get on the same page. A conversion is any meaningful action a user takes on your website or app. In the past, Google Analytics called these "Goals." Now, in GA4, any action tracked as an "event" can be marked as a conversion.

This is a big shift, but a powerful one. It means you have more flexibility. A conversion could be:

• A completed purchase (the classic e-commerce conversion)
• A submitted contact form or lead gen form
• A newsletter subscription
• A downloaded PDF
• Someone watching a key video
• A free trial signup

Your conversion rate is simply the percentage of users or sessions that complete one of these desired actions. It's one of the most important metrics for understanding if your website is actually achieving its business objectives.

Step 1: Mark Your Key Events as Conversions

Before you can find your conversion rate, you have to tell GA4 which events are your conversions. If you skip this step, you won't see any conversion data in your reports.

GA4 automatically tracks some events for you, like page_view, session_start, and scroll. E-commerce sites using the recommended setup will also have events like add_to_cart and purchase flowing in automatically.

To mark one of these existing events as a conversion, follow these simple steps:

1. Log in to your Google Analytics 4 property.
2. In the left-hand navigation, click on Admin (the gear icon at the bottom).
3. Under the Property column, navigate to Data display > Events.
4. You'll see a list of all the event names your site has collected in the selected date range. Find the event you want to treat as a conversion (e.g., generate_lead or purchase).
5. On the far right of that event's row, you'll see a toggle switch under the "Mark as conversion" column. Simply click this toggle to turn it on.

That's it! GA4 will now start treating that event as a conversion going forward. You can mark up to 30 events as conversions per property.

What if the Event I Want to Track Doesn't Exist?

Sometimes, the perfect event isn't tracked automatically. A common example is tracking a submission on a standard contact form. Typically, when a user submits your form, they are redirected to a "thank you" page.

You can create a new conversion event based on visits to this specific page.

1. Go to Admin > Data display > Events.
2. Click the Create event button.
3. Click Create again on the next screen.
4. Give your new event a descriptive name. Use snake_case (lowercase with underscores), like contact_form_submission.
5. Under Matching conditions, set it up like this:
6. Click Create.

Now, every time someone views your thank you page, GA4 will log a new contact_form_submission event. Just remember to go back to the Events list (you may need to wait 24 hours for it to appear) and mark this new event as a conversion using the toggle switch.

Step 2: Find Your Overall Conversion Rate in GA4 Reports

After you've marked your conversions and allowed some time for data to collect (at least 24-48 hours), you can start analyzing your conversion rates. GA4 offers two types of conversion rates, and it's useful to understand the difference.

• User conversion rate: The percentage of unique users who completed at least one conversion. This metric helps you understand your site's effectiveness at converting your overall audience.
• Session conversion rate: The percentage of sessions (visits) where at least one conversion occurred. This is closer to how Universal Analytics calculated "Goal Conversion Rate" and is helpful for understanding engagement on a per-visit basis.

The easiest place to find these metrics is in the Traffic Acquisition report.

1. In the left-hand navigation, go to Reports.
2. Open the Life cycle collection and click on Acquisition > Traffic acquisition.
3. Scroll the table to the right. You should see a column group for Conversions.

Here, you'll see your User conversion rate and Session conversion rate broken down by the default channel group (e.g., Organic Search, Direct, Paid Search).

Pro Tip: If you don't see the conversion rate columns, you might need to add them. Click the pencil icon (Customize report) in the top right corner of the report. Under Report data, click Metrics, then add "User conversion rate" and "Session conversion rate" from the list. Save your changes to the current report.

Step 3: Analyze Conversion Rates by Channel, Campaign, or Landing Page

Knowing your overall conversion rate is good, but the real value comes from seeing which marketing efforts are driving those conversions. The built-in reports are excellent for this.

Finding Which Marketing Channels Convert Best

The Traffic acquisition report is your best friend here. By default, it's grouped by Session default channel group. You can quickly compare performance across different channels.

For example, you might see:

• Organic Search: Session conversion rate of 3.1%
• Paid Search: Session conversion rate of 2.5%
• Email: Session conversion rate of 4.2%

This instantly tells you that your email marketing is currently your most effective channel at converting visitors, while paid search might need some optimization.

Finding Which Landing Pages Convert Best

It's just as important to know which pages on your site are pulling their weight. Are your customers converting from a blog post, a features page, or your homepage?

1. Go to Reports > Engagement > Landing page.
2. This report shows the first page a user "landed" on for a given session.
3. Again, scroll right to find the Conversions column and look at the Session conversion rate for each landing page.

This report can highlight hidden gems. You might discover an old blog post is converting visitors at an unexpectedly high rate. That's a powerful signal to create more content on that topic or to feature that page more prominently.

Go Deeper with Custom Explorations

Standard reports are great for quick answers, but sometimes you need to dig deeper. GA4's Explore section lets you build custom reports to answer more specific questions.

Let's say you want to see how your landing page conversion rates differ between desktop and mobile users.

1. In the left navigation, click Explore.
2. Start a new exploration by choosing the Free form template.
3. In the Variables column on the left, click the + icon next to DIMENSIONS. Search for and import "Landing page + query string" and "Device category."
4. Click the + icon next to METRICS. Search for and import "Conversions" and "Sessions."
5. Drag and drop your variables into the Tab Settings column:
6. Now you have a table showing conversions and sessions for each landing page, broken down by desktop, mobile, and tablet. To get a conversion rate, you need to create a custom metric:

The table will now populate, showing a clear comparison of conversion rates. You might find that some pages convert wonderfully on desktop but poorly on mobile, which could signal a need for mobile optimization.

Final Thoughts

Finding your conversion rate in Google Analytics 4 is a two-step process: first, tell GA4 what a conversion is by marking a key event, and second, find the User and Session conversion rate metrics in reports like Traffic Acquisition and Landing Page. This will give you powerful insights into what's working - and what's not - in your marketing strategy.

While GA4 reports are incredibly powerful, digging through them can sometimes feel a bit manual. At our company, we designed a tool to get these kinds of answers faster. Instead of clicking through menus and customizing reports, you can just connect your data to Graphed and ask questions in plain English, like "What is our session conversion rate by landing page for the last 30 days?" It pulls the data instantly and gives you the answer without the extra steps.
