You can’t optimize what you can’t measure. And in Google Ads, that means setting up conversion tracking properly—before you spend another dollar.
No matter how slick your ad copy is or how precise your targeting gets, if you’re not tracking conversions accurately, you’re guessing. And guesswork is expensive.
In this guide, I’ll walk you through how I set up conversion tracking for my clients—step-by-step—so you can start measuring what actually matters: results.
What You’ll Learn:
- What counts as a conversion (hint: it’s not just purchases)
- Which tracking method is best for your business
- How to set up website, phone, and form tracking
- Google Tag vs. Google Tag Manager (and when to use each)
- How to verify your tracking works
- Internal links to related campaign setup and optimization posts
What Exactly Is a Conversion in Google Ads?
A “conversion” is any action you want someone to take after clicking your ad.
Common examples:
- Filling out a contact form
- Making a purchase
- Booking a call
- Subscribing to your newsletter
- Clicking your phone number
Google Ads lets you track all of these—and more. But you have to define them first.
Choose the Right Conversion Type
Inside Google Ads, you’ll find these conversion options:
| Conversion Type | Best For |
| Website actions | Form fills, purchases, button clicks |
| Phone calls | Call extensions or number clicks from your site |
| App installs/actions | Mobile apps |
| Imports (offline) | CRM or lead scoring systems |
If you’re a service business running lead gen campaigns, you’ll likely focus on:
- Website form submissions
- Phone calls
- Clicks on “Book Now” or “Call Us” buttons

Use Google Tag or Google Tag Manager?
You’ve got two ways to install tracking:
Google Tag (formerly Global Site Tag)
- Add a code snippet directly to your website’s header.
- Simple, works well for smaller sites or single-purpose tracking.
Google Tag Manager
- A container that lets you manage multiple tags (not just Google Ads).
- Better for teams, agencies, or sites using multiple platforms.
My take: If you’re managing one site and want it done fast, Google Tag is fine. If you want long-term flexibility or you’re working with developers, go with Tag Manager.
How to Set Up Website Conversion Tracking (Step-by-Step)
Here’s how to set up a basic website conversion—like a form submission:
Step 1: Go to Tools & Settings → Conversions
In Google Ads, click the wrench icon, then choose Conversions.
Step 2: Click “New Conversion Action” → Website
Enter your domain. Google will scan it and confirm the tag options.
Step 3: Define the Action
Choose what type of conversion this is:
- Lead
- Purchase
- Sign-up
- Contact
Name your conversion something clear, like “Contact Form Submission.”
Set value as:
- Fixed (e.g., $50 per lead)
- Don’t use a value (for lead gen without fixed value)
Set the count to:
- One (for leads)
- Every (for purchases)
Step 4: Install the Tag
Choose:
- Google Tag (manual or via CMS)
- Google Tag Manager (if already set up)
Place the code in your site’s <head> or fire it with a Tag Manager trigger.
Want to improve what happens after they convert? Here’s how to optimize landing pages.
Track Phone Calls from Ads or Your Website
You can track calls from:
- Google call extensions (the number shown in your ad)
- Clicks on a number on your website (mobile only)
To track ad call extensions:
- Go to “Conversions” → “Phone Calls”
- Choose “Calls from Ads”
- Set your business hours and count settings
- Add the call extension to your ads
To track website number clicks:
- Choose “Calls to a phone number on your website”
- Google will give you a snippet to wrap around your number
- Only works if your number is clickable (tel:)
This is key if phone calls = customers for your business.
Track Button Clicks & Thank-You Pages
You can track two types of web actions:
Option 1: Thank-You Page URL
The easiest method. Set the conversion to fire when someone lands on a “thank you” page after submitting a form or checking out.
Just enter the page URL in the setup.
Option 2: Button Click Tracking
Use this when your site doesn’t redirect after submission.
You’ll need:
- Google Tag Manager installed
- A trigger for the button click
- A tag firing your Google Ads conversion
This one’s a bit more technical, but great for one-page forms or modal submissions.

Test & Verify Your Tracking (Please Don’t Skip This)
So you’ve added your tag. Great. Now make sure it actually works.
Use:
- Google Tag Assistant: A browser extension that verifies tags are firing.
- Google Ads Conversion Troubleshooter: Found in Tools → Conversions
- Google Analytics (if linked): Cross-check events vs. conversion triggers
Run a test submission and watch for a “conversion” in the real-time report.
Link Google Ads With Google Analytics
Linking these two unlocks better insights and helps track cross-platform behavior.
Benefits:
- See which campaigns drive actual engagement
- Import goals from Analytics as conversions
- Retarget based on site behavior
To do this:
- Go to Google Ads → Tools → Linked Accounts
- Find Google Analytics (GA4) and connect
- Choose which events or goals to import
Now your ads will be smarter—and so will your reporting.
Set Up Conversion Columns in Your Reports
What’s the point of tracking if you never see the data?
Head to Campaigns → Columns → Modify Columns
Add:
- Conversions
- Conversion rate
- Cost per conversion
- All conversions (if you want phone + form combined)
This way, you can spot winning keywords, ads, and audiences faster.

Tracking = Profit (or Waste)
Running Google Ads without conversion tracking is like playing darts blindfolded. You’re probably missing. And wasting budget doing it.
Track leads. Track sales. Track calls. Track form fills. If it matters to your business, make it a conversion.
Start simple: a thank-you page or call extension is a great first step. Then layer in button clicks, scrolls, video views, and anything else that moves people toward a sale.
