Tracking conversions in Google Ads is one of the most important aspects of any digital marketing campaign. Without proper tracking, you’ll never know which ads, keywords, or audiences are actually delivering results. Whether you are generating sales, getting calls, or collecting leads, Google Ads Conversion Tracking allows you to measure every meaningful action your customers take.
In this detailed guide, we’ll discuss step-by-step how to set up conversion tracking in Google Ads, understand important Google Ads Metrics, and learn how to track calls and leads effectively.
1. What is Google Ads Conversion Tracking?
Google Ads Conversion Tracking is a free tool that helps you measure the effectiveness of your ad campaigns by showing you what happens after a user clicks on your ad — whether they make a purchase, fill out a form, call your business, or download an app.
Essentially, it connects the dots between your ad spend and real business results. For example, if you are running ads for a dental clinic, you can track how many people filled out an appointment form or called your clinic after clicking the ad.
2. Why Google Ads Conversion Tracking is Important
Without conversion tracking, you’re flying blind. You may be spending money on clicks that don’t bring any revenue. Conversion tracking helps you:
- Identify which keywords and ads drive results.
- Optimize campaigns for better ROI.
- Understand customer behavior.
- Track phone calls, sign-ups, sales, and form submissions.
- Use Google Ads Metrics like conversion rate and cost per conversion to measure success.
In short, it’s your performance measurement system — without it, you can’t make data-driven decisions.

3. Types of Conversions You Can Track
Google Ads allows you to track multiple types of conversions depending on your business goal:
- Website Actions: Form submissions, purchases, downloads, or sign-ups.
- Phone Calls: Calls made directly from your ad or after visiting your website.
- App Installs and In-App Actions: For mobile app campaigns.
- Offline Conversions: Sales or leads that happen after an in-person visit or phone call.
- Import Conversions from CRM: If you use tools like HubSpot or Zoho, you can import conversion data.
Tracking these conversions helps you know where your advertising budget is most effective.
4. How to Set Up Google Ads Conversion Tracking (Step-by-Step)
Setting up Google Ads Conversion Tracking requires only a few steps but must be done carefully to get accurate data.
Step 1: Sign In to Google Ads
Go to your Google Ads account and click on the Tools & Settings icon (wrench symbol) in the top menu.
Step 2: Choose “Conversions”
Under the “Measurement” section, select Conversions. This is where you’ll create and manage all your conversion actions.
Step 3: Create a New Conversion Action
Click the + New Conversion Action button. You’ll be asked to choose the source of conversions:
- Website
- App
- Phone calls
- Import (offline conversions)
Choose Website if you want to track form fills, purchases, or button clicks.
Step 4: Set Up Conversion Details
Now enter details like:
- Conversion Name: e.g., “Lead Form Submission.”
- Value: Assign a value (optional) to each conversion.
- Count: Choose whether to count every conversion or only unique ones.
- Click-through Conversion Window: Usually 30 days by default.
Step 5: Install the Conversion Tracking Tag
After saving, Google Ads will provide you with a small piece of HTML code (tag). You or your web developer must add this tag to your website’s conversion page — usually the Thank You Page that appears after a user completes a form or makes a purchase.
Step 6: Verify the Tag
Use the Google Tag Assistant or Google Tag Manager to confirm that your conversion tag is firing correctly.
Once done, Google Ads will start recording conversions whenever a user completes the defined action.

5. Tracking Calls and Leads
One of the most valuable conversions for service-based businesses is phone calls and leads. With Google Ads, you can track calls in three main ways:
1. Calls from Ads
You can enable the “Call Extension” or “Call Only Ads.” Google will assign a unique forwarding number that tracks how many users called directly from the ad.
2. Calls from Website
If users click your ad, visit your website, and then call you from the number displayed, Google can still track it using a website call tracking tag.
3. Lead Form Conversions
If you have a contact form or a lead generation form, track when users fill and submit it using your conversion tracking tag.
This data helps you understand how well your ads are generating real business inquiries and how much you’re paying per call or lead.
6. Understanding Google Ads Metrics
Once conversion tracking is active, you can analyze performance using Google Ads Metrics. Here are the most crucial ones:
| Metric | Description |
|---|---|
| Conversions | Total number of actions (like purchases or leads). |
| Conversion Rate (CVR) | Percentage of clicks that result in conversions. |
| Cost Per Conversion (CPA) | Average amount spent to get one conversion. |
| Conversion Value | Total value of all conversions. |
| ROAS (Return on Ad Spend) | Conversion value ÷ Ad spend — shows profitability. |
| Call Conversions | Number of calls generated from ads or website. |
Understanding these metrics helps you make smarter optimization decisions.
Bid Strategies in Google Ads: Manual vs Automated
Example 1: Tracking Conversions for an E-Commerce Store
Let’s say you run an online store selling mobile accessories. You want to know which ads generate sales.
- Step 1: You create a conversion action for “Purchase Completed.”
- Step 2: You place the Google Ads tag on the “Thank You” page after a successful order.
- Step 3: Each time someone clicks an ad, buys a charger, and reaches the Thank You page, Google Ads counts it as one conversion.
- Result: You can now see how many conversions came from each keyword (e.g., “20W Type-C Charger”) and optimize bids for the most profitable ones.
Example 2: Tracking Conversions for a Local Business
Suppose you manage Google Ads for a dental clinic in Delhi that wants more appointment bookings.
- Step 1: Create a “Lead Form Submission” conversion in Google Ads.
- Step 2: Add the conversion tag on the “Thank You” page that appears after patients book an appointment online.
- Step 3: Also, enable “Call Extensions” to track phone calls from your ad.
- Result: You’ll know how many calls or form submissions your ads are generating and the exact cost per lead.
This approach ensures you spend money only on campaigns that bring real clients.
7. Best Practices for Accurate Conversion Tracking
- Always verify tags: Use Google Tag Assistant or Tag Manager to test your tags.
- Exclude duplicate conversions: Avoid counting multiple actions from the same user.
- Use Google Analytics integration: Link your Analytics account with Google Ads for deeper insights.
- Track micro conversions: Such as add-to-cart, time spent, or page views to understand the customer journey.
- Set conversion values: Assign estimated monetary value to every lead or sale for better ROI tracking.
- Use call tracking numbers: Especially for service-based businesses to measure calls effectively.
- Check conversion lag: Some conversions take time — don’t judge campaigns too early.

8. How to Analyze and Optimize Based on Conversions
Once your conversion data starts flowing, use it to improve campaign performance:

- Refine ad copy: See which ads convert best and use similar messaging in others.
