How to set up Google Ads tracking

Q: Should I track conversions in Google Ads or import from GA4?

Either can work. Pick one primary source per action to avoid double counting.

Q: How long until conversions show up?

Many appear within hours, but some take a day or more depending on the conversion window and processing.

Introduction

Quick answer: To set up Google Ads tracking, create a conversion action in Google Ads (Goals, then Conversions), install the Google tag on your site and add the event snippet for that conversion, or import a GA4 key event. Turn on enhanced conversions, test with Tag Assistant, and confirm the conversion status shows as recording before you rely on automated bidding.

Why conversion tracking matters

Google Ads can only optimize toward what it can measure. Without correct conversion tracking you cannot tell which keywords make money, and smart bidding has nothing meaningful to learn from.

Decide what to track

Primary actions: purchases, qualified leads, booked calls.
Secondary actions: add to cart, key page views, newsletter sign-ups, used for observation rather than bidding.

Use only your real business outcomes as primary conversions that bidding optimizes for.

Method comparison

Method	How it works	Good for
Google tag plus event snippet	Code fires on the thank-you page or event	Simple sites
Google Tag Manager	Conversion Linker and Conversion Tracking tags with triggers	Sites with multiple tags
Import from GA4	Mark a GA4 key event and import it into Google Ads	Teams already trusting GA4 data
Offline conversion import	Upload sales from your CRM with the click ID	Lead gen with sales closed later
Call and form tracking	Call conversions and form submit events	Service businesses

Step 1: Create the conversion action

In Google Ads, open Goals, then Conversions, then Summary.
Choose New conversion action and pick Website.
Enter your domain and let Google scan, or add the action manually.
Set the category, a clear name, a value (a fixed value, or dynamic values for purchases) and the count: one per click for leads, every for sales.
Set the attribution model and conversion window that suit your sales cycle.

Step 2: Install the tag

Add the Google tag to all pages, then add the event snippet to the page or event that signals success, such as the order confirmation. With Google Tag Manager, add a Conversion Linker tag on all pages and a Conversion Tracking tag triggered on the right event, with value and transaction ID variables for ecommerce.

Step 3: Turn on enhanced conversions

Enhanced conversions use hashed first-party data such as email, sent when a customer completes a conversion, to improve measurement. Enable it in the conversion settings, choose the tag or API setup method, and follow Google’s customer data terms and your consent requirements.

Step 4: Test it

Use Tag Assistant to confirm the tag fires on the correct step only.
Complete a test conversion and check the Conversions column after processing time.
Check the conversion action status: recording conversions, inactive or no recent conversions.
For ecommerce, confirm the value and currency are correct.

Step 5: Connect with Analytics

Link Google Ads with GA4 for audiences and cross-checking. Compare Google Ads conversions and GA4 numbers directionally, knowing attribution differs between them.

Common mistakes

Firing the tag on page load of a form page rather than the success page.
Counting every page view as a conversion.
Importing many secondary actions as primary, which confuses bidding.
Ignoring cookie consent, which can reduce measurement. Consider Consent Mode.

Frequently asked questions

Should I track conversions in Google Ads or import from GA4?

Either can work. Google Ads native tags are simple and direct. GA4 imports keep a single source of truth. Pick one primary source per action to avoid double counting.

How long until conversions show up?

Many appear within hours, but some can take a day or more depending on the conversion window and processing. Check the status of the conversion action.

What are enhanced conversions?

They send hashed first-party customer data with a conversion to help Google match it to ad interactions more accurately.
