# [How to Set Up Google Ads Conversion Tracking (Step-by-Step Guide)](https://conversite.net/blog/how-to-set-up-google-ads-conversion-tracking)

If you're running Google Ads without conversion tracking, you're essentially flying blind. You might be getting clicks — but you have no idea which campaigns, keywords, or ads are actually driving leads, purchases, or sign-ups.

Conversion tracking fixes that. It tells Google (and you) exactly which actions on your website matter, so your campaigns can optimise toward real results — not just traffic.

This guide walks you through the complete setup, step by step.

 

## What Is Google Ads Conversion Tracking?

Google Ads conversion tracking is a free tool that records what happens after someone clicks your ad. A **conversion** is any action you define as valuable — a form submission, a purchase, a phone call, a page visit, or a file download.

When conversion tracking is set up correctly, Google can:

- Report on how many conversions each campaign, ad group, keyword, and ad generated
- Use that data to automate your bidding (Smart Bidding strategies like Target CPA or Target ROAS)
- Help you calculate your true return on ad spend (ROAS)

Without it, you're optimising for clicks. With it, you're optimising for business outcomes.

 

## Types of Conversions You Can Track

Before setting anything up, decide what you want to track. Common conversion types include:

- **Website actions** — form submissions, button clicks, page visits, purchases
- **Phone calls** — calls from your ads or from a number on your website
- **App downloads or in-app actions** — for mobile app campaigns
- **Imported conversions** — data from your CRM or other analytics tools (like Google Analytics 4)

For most small and medium businesses, **website actions** are the starting point.

 

### Step 1: Create a Conversion Action in Google Ads

1. Sign in to your [Google Ads account](https://ads.google.com)
2. Click the **Goals** icon in the left navigation (it looks like a target)
3. Select **Conversions** → **Summary**
4. Click the blue **+ New conversion action** button
5. Select **Website** as the conversion source

You'll now be asked to enter your website URL. Google will scan your site and suggest conversion actions it detected automatically — you can use these or create a custom one.

 

### Setting Up a Custom Conversion Action

If you're setting up manually:

1. Choose the **Category** (e.g. "Submit lead form", "Purchase", "Page view")
2. Name your conversion — be specific (e.g. "Contact Form Submission — Homepage")
3. Set the **Value** — if each lead is worth a fixed amount to your business, enter it. Otherwise, select "Don't use a value"
4. Set **Count** — for lead forms, choose "One" (one form submit = one conversion). For e-commerce, choose "Every" (each purchase counts separately)
5. Set the **Click-through conversion window** — 30 days is standard for most lead gen campaigns
6. Choose your **Attribution model** — "Data-driven" is recommended if you have enough data; otherwise use "Last click"
7. Click **Save and continue**

### Step 2: Install the Google Tag

Google will now give you a **conversion tracking tag** — a snippet of JavaScript that goes on your website. There are two parts:

- **Google tag (gtag.js)** — the base tag that goes on every page of your site
- **Event snippet** — goes only on the page that confirms a conversion (e.g. your "Thank you" page after a form submission)

You have three installation options:

#### Option A: Install via Google Tag Manager (Recommended)

If you're using Google Tag Manager (GTM), this is the cleanest method.

1. In Google Ads, select **"Use Google Tag Manager"**
2. Copy your **Conversion ID** and **Conversion Label** (you'll need these in GTM)
3. Open [Google Tag Manager](https://tagmanager.google.com)
4. Click **New Tag** → Tag Configuration → **Google Ads Conversion Tracking**
5. Paste in your Conversion ID and Conversion Label
6. Under **Triggering**, click the + button and select your trigger — for a thank-you page, use a **Page View** trigger with the URL matching `/thank-you` (or whatever your confirmation page URL is)
7. Name your tag (e.g. "GA - Contact Form Conversion") and click **Save**
8. Click **Submit** to publish the GTM container

#### Option B: Install Directly on Your Website

1. Copy the **Google tag** snippet and paste it into the `<head>` section of every page on your site
2. Copy the **event snippet** and paste it into the `<head>` of your conversion confirmation page only

If you're on HubSpot CMS (like Conversite), go to **Settings → Website → Pages → Site Header HTML** to add the global tag, and add the event snippet directly in the head HTML of your thank-you page.

 

#### Option C: Use the Google Ads Tag Assistant

Google offers a browser extension — [Tag Assistant](https://tagassistant.google.com/) — that can automatically install the tag for you on some platforms. This is the easiest option but has limited platform support.

 

### Step 3: Verify Your Conversion Tag Is Firing

Don't skip this step. A tag that isn't firing means you're collecting no data — and you might not realise for weeks.

 

#### Using Google Tag Assistant (Chrome Extension)

1. Install the [Google Tag Assistant Legacy](https://chrome.google.com/webstore/detail/tag-assistant-legacy-by-g/kejbdjndbnbjgmefkgdddjlbokphdefk) Chrome extension
2. Navigate to your website and activate the extension
3. Complete the conversion action (submit the form, click the button, visit the thank-you page)
4. Check that your Google Ads tag shows as green (firing correctly)

#### Using Google Ads Conversion Status

Back in Google Ads:

1. Go to **Goals** → **Conversions** → **Summary**
2. Find your conversion action in the list
3. Check the **Status** column — it should show "Recording conversions" within a few hours of your first test conversion

If it shows "Unverified", the tag hasn't fired yet. If it shows "No recent conversions", the tag is installed but no conversions have happened.

 

### Step 4: Import Google Analytics 4 Conversions (Optional but Recommended)

If you have GA4 set up, you can import your GA4 conversion events directly into Google Ads rather than managing two separate tracking setups.

1. In Google Ads, go to **Goals** → **Conversions** → **Summary**
2. Click **+ New conversion action** → **Import**
3. Select **Google Analytics 4 properties**
4. Choose which GA4 events to import as conversions
5. Click **Import and continue**

This approach gives you richer attribution data across all channels, not just paid clicks.

 

### Step 5: Set Your Primary Conversion Action

If you have multiple conversion actions set up, make sure Google knows which one matters most for bidding.

1. Go to your conversion action settings
2. Under **Optimise for conversions**, make sure your main conversion (e.g. form submission) is set to **Primary** — this is what Smart Bidding will optimise toward
3. Secondary conversions (e.g. page visits) can be set to **Secondary** — they'll be tracked but won't influence bidding

## Common Mistakes to Avoid

**Tracking the wrong page as a conversion.** Make sure your event snippet fires on the *confirmation* page, not the form page itself. If someone lands on `/thank-you` without submitting a form, that shouldn't count.

**Double-counting conversions.** If you import GA4 conversions AND have a native Google Ads tag on the same action, you'll count it twice. Use one method per conversion type.

**Not setting a conversion value.** Even a rough estimate of lead value helps Google's Smart Bidding make better decisions. If a closed deal is worth $2,000 and you close 1 in 10 leads, each lead is worth approximately $200.

**Forgetting to test.** Always complete a test conversion after setup. Forms with honeypot fields or CAPTCHA can sometimes interfere with tag firing.

 

## What to Do After Setting Up Conversion Tracking

Once your tracking is live and verified:

- Wait 2–4 weeks to accumulate enough conversion data before switching to Smart Bidding strategies
- Review your **Search terms report** to understand what queries are driving conversions (not just clicks)
- Use conversion data to pause underperforming keywords and scale keywords that convert well
- Consider setting up **Audience segments** based on converters for remarketing campaigns

Conversion tracking is the foundation everything else is built on. If you're planning to scale your Google Ads spend, this is the single most important thing to get right first.

 

## Frequently Asked Questions

**How long does it take for conversion tracking to start working?** Once the tag is installed and verified, conversions start recording immediately. It typically takes 24–48 hours for data to appear in your Google Ads reports.

**Does Google Ads conversion tracking work with HubSpot forms?** Yes. If your HubSpot form redirects to a thank-you page after submission, place the event snippet on that thank-you page. Alternatively, use GTM to fire the conversion tag on the form submission event.

**Can I track phone calls with Google Ads conversion tracking?** Yes. Google offers two types of call tracking: calls from your ads (using a Google forwarding number shown in the ad) and calls from your website (using a dynamically inserted tracking number on your site).

**What's the difference between conversion tracking and Google Analytics?** Google Analytics tracks all website behaviour across all traffic sources. Google Ads conversion tracking focuses specifically on actions that followed a click on one of your Google Ads. For the most complete picture, use both.

**Is Google Ads conversion tracking free?** Yes, it's completely free. You only pay for the ad clicks themselves.
