Why Conversion Tracking in Google Ads Matters More Than Ever
Running Google Ads without conversion tracking is like driving with your eyes closed. You might be spending hundreds or thousands of dollars each month, but you have no way of knowing which keywords, ads, or campaigns are actually generating results.
Conversion tracking tells Google Ads what happens after someone clicks your ad. Did they buy something? Fill out a form? Call your business? Without this data, Google’s Smart Bidding algorithms cannot optimize your campaigns, and you are left guessing.
In this guide, we walk you through exactly how to set up conversion tracking in Google Ads for website actions, phone calls, and imports from Google Analytics 4. We also cover testing, verification, and the most common setup errors that waste budgets every single day.
What Counts as a Conversion in Google Ads?
Before diving into the technical setup, it helps to understand the types of conversions you can track. Google Ads supports several categories:
| Conversion Type | What It Tracks | Best For |
|---|---|---|
| Website actions | Purchases, form submissions, button clicks, page views | E-commerce, lead generation, SaaS |
| Phone calls | Calls from ads, calls from your website, clicks on phone numbers | Local businesses, service companies |
| App installs and in-app actions | Downloads, sign-ups, in-app purchases | Mobile apps |
| Imports (GA4, CRM, offline) | Events from Google Analytics 4 or offline sales data | Businesses with longer sales cycles, B2B |
Most advertisers will need to set up at least website action tracking. Many will also benefit from phone call tracking and GA4 imports. We will cover all three below.
Step 1: Create a Conversion Action in Google Ads
The first step in setting up conversion tracking is always to define what you want to track inside your Google Ads account. Here is how:
- Sign in to your Google Ads account at ads.google.com.
- In the left-hand menu, click Goals, then Conversions, then Summary.
- Click the blue + New conversion action button.
- Select the source of your conversion. For most setups, choose Website.
- Enter your website URL. Google will scan it to check if a Google tag is already installed.
- Choose how you want to set up your conversion: manually using code, or by using a URL (for simple thank-you page tracking).
Configuring Conversion Action Settings
When you create the action, you will need to fill in several important fields:
- Conversion name: Use a descriptive name like “Purchase,” “Lead Form Submit,” or “Demo Request.”
- Value: Assign a monetary value if possible. For e-commerce, use dynamic values. For leads, you can assign a static estimated value.
- Count: Choose “Every” for purchases (each transaction matters) or “One” for leads (you only want to count one conversion per click).
- Click-through conversion window: The default is 30 days. Extend it if your sales cycle is longer.
- View-through conversion window: Usually 1 day is fine for most businesses.
- Attribution model: Google now defaults to data-driven attribution. Keep this unless you have a specific reason to change it.
Click Done and then Save and continue. Google Ads will now show you options for installing the tracking tag on your site.
Step 2: Install the Google Tag on Your Website
Once you have created a conversion action, you need to place code on your website so Google Ads can detect when that conversion happens. There are three main ways to do this:
Option A: Install the Google Tag Directly on Your Website
This method places a global site tag (the Google tag) into the <head> section of every page on your site, plus an event snippet on your conversion page (like a thank-you page).
- After saving your conversion action, Google Ads will display a Google tag code snippet and an event snippet.
- Copy the Google tag and paste it between the
<head>and</head>tags on every page of your website. - Copy the event snippet and paste it on only the page where the conversion happens (for example, the order confirmation page or the thank-you page), right after the Google tag.
- Save and publish your changes.
Tip: If you use WordPress, plugins like Insert Headers and Footers or WPCode make it easy to add the Google tag without editing theme files.
Option B: Install via Google Tag Manager (Recommended)
Google Tag Manager (GTM) is the preferred method for most advertisers because it gives you more control and does not require editing your site code every time you want to track something new.
- Log in to your Google Tag Manager account at tagmanager.google.com.
- Click Add a new tag.
- Name your tag (for example, “Google Ads Conversion – Purchase”).
- Under Tag Configuration, select Google Ads Conversion Tracking.
- Enter your Conversion ID and Conversion Label. You can find these in your Google Ads account under the conversion action details.
- If you are tracking dynamic values (like purchase amounts), map the Conversion Value and Currency Code fields to your data layer variables.
- Under Triggering, select the appropriate trigger. For a thank-you page, create a trigger that fires on the specific page URL. For a button click, use a click trigger.
- Click Save, then Submit your container to publish the changes.
Important: You also need a Google Ads Conversion Linker tag in GTM. This tag ensures that click data from your ads is properly passed through. Create it by adding a new tag, selecting “Conversion Linker” as the tag type, and setting it to fire on all pages.
Option C: Use Google Tag via Your CMS or Website Builder
Many platforms like Shopify, Wix, Squarespace, and WordPress have native Google Ads integrations. Check your platform’s settings for a field where you can paste your Google Ads Conversion ID and label directly.
Step 3: Set Up Phone Call Conversion Tracking
If phone calls are valuable to your business, Google Ads offers three ways to track them:
Calls from Ads (Call Extensions or Call-Only Ads)
- Go to Goals > Conversions > Summary and click + New conversion action.
- Select Phone calls.
- Choose Calls from ads using call extensions or call-only ads.
- Configure the conversion name, call length (for example, count calls longer than 60 seconds as conversions), and value.
- Save. Google will automatically track qualifying calls from your call extensions.
Calls to a Phone Number on Your Website
This method uses a dynamic phone number swap. Google replaces the phone number displayed on your site with a Google forwarding number so it can attribute calls back to specific ad clicks.
- Create a new phone call conversion action and select Calls to a phone number on your website.
- Enter your actual business phone number.
- Set the minimum call duration to count as a conversion.
- Install the Google tag on your website (if not already installed) and add the phone snippet provided by Google Ads.
Note: Google forwarding numbers are not available in all countries. Check Google Ads Help for availability in your region.
Clicks on a Phone Number on Your Mobile Website
This tracks when someone taps a clickable phone number link on a mobile device. Set it up through GTM using a click trigger that listens for clicks on tel: links.
Step 4: Import Conversions from Google Analytics 4
If you are already tracking events in Google Analytics 4, you can import those events as conversions into Google Ads. This is especially useful if you have complex conversion setups already running in GA4.
- Make sure your Google Ads and GA4 accounts are linked. In GA4, go to Admin > Google Ads Links and connect your accounts.
- In Google Ads, go to Goals > Conversions > Summary.
- Click + New conversion action and select Import.
- Choose Google Analytics 4 properties, then select Web.
- You will see a list of GA4 events. Select the events you want to import as conversion actions.
- Click Import and continue.
When should you use GA4 imports instead of the Google Ads tag?
- When you want consistent conversion data across Google Ads and GA4 reports.
- When you already have advanced event tracking set up in GA4 and do not want to duplicate effort.
- When you need to track conversions that span multiple sessions or involve complex user journeys.
However, keep in mind that Google Ads native conversion tracking (via the Google tag or GTM) typically provides more accurate data for bidding optimization because it uses first-party cookies tied directly to ad clicks. For best results, many experts recommend using the Google Ads tag as your primary conversion source and GA4 imports as a secondary reference.
Step 5: Test and Verify Your Conversion Tracking
Setting up the tag is only half the job. If your tracking does not fire correctly, your data will be wrong and your campaigns will suffer. Here is how to verify everything works:
Use Google Tag Assistant
- Install the Google Tag Assistant Chrome extension (or use the Tag Assistant built into GTM).
- Navigate to your conversion page (the thank-you page, for example).
- Check that the Google tag and the conversion event snippet are both firing.
- Look for green status indicators. Yellow or red flags indicate issues.
Use GTM Preview Mode
If you installed your tags via Google Tag Manager:
- Click Preview in the top-right corner of your GTM workspace.
- Enter your website URL. A debug window will open.
- Complete the conversion action on your site (submit a form, make a test purchase, etc.).
- In the debug panel, confirm that the Google Ads Conversion Tracking tag and the Conversion Linker tag both fired on the correct trigger.
Check in Google Ads
- Go to Goals > Conversions > Summary.
- Look at the Status column next to your conversion action.
- It may take up to 24 hours for the status to update. Possible statuses include:
- Unverified: Google has not received any conversion data yet.
- No recent conversions: The tag was verified in the past but has not tracked anything recently.
- Recording conversions: Everything is working correctly.
- Tag inactive: The tag has not fired for an extended period.
Send a Test Conversion
The most reliable way to test is to click on your own ad (use a small budget test campaign if needed), complete the conversion action, and then check the Google Ads reports after 24 to 48 hours. You can also check the Real-time report in GA4 if you are using GA4 imports.
Common Conversion Tracking Errors to Avoid
After years of auditing Google Ads accounts, here are the most frequent mistakes we see at King Content Agency:
1. Missing the Conversion Linker Tag in GTM
Without the Conversion Linker tag, Google cannot properly connect ad clicks to conversions. This is the single most common reason for underreported conversions when using Google Tag Manager.
2. Double-Counting Conversions
This happens when you track the same action through both the Google Ads tag and a GA4 import. Check your conversion actions list and make sure you are not importing GA4 events that you are already tracking natively.
3. Tracking the Wrong Page
Placing the event snippet on your landing page instead of the thank-you page will count every visitor as a conversion. Always verify that the snippet fires only after the desired action is complete.
4. Not Assigning Conversion Values
Without values, Google’s Smart Bidding strategies like Maximize Conversion Value or Target ROAS cannot work properly. Even for lead generation, assign an estimated value to each conversion type.
5. Using the Wrong Count Setting
Setting the count to “Every” for a lead form means that if someone submits the form three times, you record three conversions. For leads, use “One.” For purchases, use “Every.”
6. Forgetting to Update After Website Changes
Website redesigns, URL changes, or CMS migrations can break conversion tracking. After any significant website change, re-test all your conversion actions immediately.
7. Not Excluding Internal Traffic
Your own team testing the site can trigger false conversions. Use IP exclusions in Google Ads or set up filters in GTM to prevent internal traffic from skewing your data.

Frequently Asked Questions
Is Google Ads conversion tracking free?
Yes. Google Ads conversion tracking is completely free to use. You create conversion actions inside your Google Ads account and install tracking tags on your website at no additional cost. Google Tag Manager is also free.
What is the first step in setting up conversion tracking in Google Ads?
The first step is to create a conversion action inside your Google Ads account. Go to Goals > Conversions > Summary, click “+ New conversion action,” and define what you want to track. After that, you install the tracking tag on your site.
How long does it take for conversion tracking to start working?
Once the tag is properly installed and someone completes a conversion, data usually appears in Google Ads within 24 hours. In some cases, it can take up to 48 hours. The conversion action status will update from “Unverified” to “Recording conversions” once data starts flowing.
Should I use Google Ads conversion tracking or import from GA4?
For most advertisers, using the Google Ads native conversion tag (either directly or through GTM) delivers more accurate data for bidding. GA4 imports are a good complement, especially if you want unified reporting. Avoid using both for the same conversion action, as this causes double-counting.
How do I track conversions with Google Ads if I don’t have a thank-you page?
If your website does not redirect to a dedicated thank-you page after a form submission, you can use event-based tracking. With Google Tag Manager, create a trigger that fires when the form submission button is clicked or when a success message element appears on the page. You can also push custom events to the data layer from your form handler code.
How can I check if my conversion tracking is working?
Use the Google Tag Assistant browser extension, GTM Preview mode, or check the status column in your Google Ads conversion actions table. You can also perform a real test by clicking an ad and completing the conversion, then checking the reports after 24 hours.
Why is my Google Ads conversion tracking not working?
The most common reasons include: the Google tag is not installed on all pages, the Conversion Linker tag is missing in GTM, the event snippet fires on the wrong page, or your website recently changed URLs and the trigger no longer matches. Run through the checklist above to diagnose the issue.
Final Thoughts
Setting up conversion tracking in Google Ads is not optional. It is the foundation of every successful paid search campaign. Without it, you cannot measure ROI, optimize bids, or make informed decisions about your ad spend.
The good news is that once you set it up properly, it mostly runs on autopilot. The key is to get it right from the start, test thoroughly, and revisit your setup whenever your website or business goals change.
