How to set up Google Ads conversion tracking

This guide walks you through installing the Google tag, creating your first conversion actions, turning on enhanced conversions, and confirming everything records correctly before you rely on it for bidding.

Conversion tracking tells Google Ads which clicks turned into sales, leads, or calls. It powers your reports and is the data Smart Bidding learns from, so it matters more than almost any campaign setting.

There are two parts. The Google tag is a site-wide snippet that loads on every page. A conversion action defines what counts, such as a purchase confirmation page or a form submission event. Enhanced conversions add hashed customer data to improve measurement, and consent mode passes visitors’ privacy choices to Google.

Decide what counts as a conversion

List the actions that mean money for the business: purchases, qualified lead forms, booked calls. Each will become a conversion action. Mark the ones you want bidding to optimize toward as primary, and keep softer signals such as page views or add to cart as secondary, which reports them without steering bids.

Start a conversion action and scan your site

Open the Goals menu, select Summary, then + Create conversion action. Select Edit data sources for conversions on a website, enter your domain, and select Scan. If Google finds a Google tag or a linked Google Analytics property, select Done. If it finds nothing, choose Set up to install a Google tag.

Install the Google tag on every page

Place the Google tag snippet immediately after the opening head tag on every page you want to measure. Google recommends deploying through Google Tag Manager if you use it. If a Google Analytics tag is already installed, add your Google Ads ID to the existing tag rather than adding a second full snippet.

Watch outTwo copies of the Google tag, one hard-coded and one in Tag Manager, are a common cause of double-counted conversions.

Create the conversion action

Pick a category, then choose how to measure. Automatically without code lets you count a conversion when someone reaches a URL that matches a rule, such as a thank-you page. Manually using code gives you an event snippet to place on the conversion page after the Google tag. On the Use Google Tag Manager tab, select Set up in Google Tag Manager to add the tags to a container.

Use the Shopify integration if you sell on Shopify

Shopify stores can connect Google Ads through the Google & YouTube app. Once linked, purchase conversions are driven by Shopify’s checkout completed event, and Google deduplicates conversions from the Google tag and Shopify’s server-side integration before attribution. Purchases are the only supported conversion event in this integration for now, so track leads or other actions separately.

Set value, count, and enhanced conversions

In the conversion settings, set a value, choose whether to count every conversion or one per click, and confirm the conversion windows. To turn on enhanced conversions, open Goals, select Settings, expand Enhanced conversions, check the turn-on box, review the customer data terms and select Agree, then choose Google tag as the method. Customer data such as email is hashed with SHA256 before it is sent.

Add consent mode if you need it

Consent mode passes visitors’ cookie choices to Google tags. It uses four settings: ad_storage, analytics_storage, ad_user_data, and ad_personalization. A default is set on every page before tags fire, and updated when the visitor chooses. Google notes that both ad_user_data and ad_personalization must be granted for remarketing. Most consent banner platforms support Google consent mode.

Verify with Tag Assistant and conversion status

Go to tagassistant.google.com, select Add domain, enter your URL, and select Connect. Browse to your conversion page and confirm the Google tag and conversion event fire. In Google Ads, statuses such as Unverified, No recent conversions, and Recording conversions show progress; Google says updates can take up to 48 hours.

Complete a real test purchase or form, then check it records. The enhanced conversions diagnostics report becomes available about 72 hours after setup.

Before you move on

  • The Google tag loads once on every page
  • Each conversion action fires on the right page or event only
  • Primary conversions are only the actions that matter
  • Enhanced conversions are on and terms accepted
  • A test conversion shows up in Google Ads

Where DIY setups go wrong

The most common problems with self-built Google Ads setups, and what they cost.

Counting the same conversion twice

Duplicate tags, or a Google Analytics import and a Google Ads tag both set as primary for the same action, inflate results. Smart Bidding then optimizes toward numbers that are not real.

Making every action primary

When page views or add to cart are primary, bidding chases cheap signals instead of sales or leads. Keep secondary actions for observation.

Thank-you pages that load without a conversion

If a confirmation URL can be reached by refresh, bookmark, or direct link, URL-based conversions over-count. Event-based tracking is more reliable.

Ignoring consent for EEA and UK visitors

Without consent mode signals, conversion measurement and remarketing for those visitors are limited. It is a legal question as much as a tracking one.

Never checking after launch

Site changes, new checkout apps, and theme updates break tags quietly. A conversion action that stops recording can go unnoticed for weeks.

What this guide doesn't cover

Basic tracking tells you a conversion happened. Profitable bidding needs more: accurate values, deduplicated data across tag and server sources, offline conversions for leads that close later, and a clear view of how Google’s attribution compares with your own sales data.

ADM builds tracking for Google Ads with enhanced conversions, Google Analytics 4, and offline conversion imports so the bidding systems learn from what actually makes the business money.

  • Offline conversion imports for leads that close by phone or in a CRM
  • Conversion value rules and profit-based values
  • Server-side tagging and Google tag gateway setups
  • Consent mode implementation with your consent platform
  • Attribution settings and reconciliation with backend sales
  • Ongoing tag health monitoring

Common questions

Do I need Google Tag Manager?

No. You can paste the Google tag directly into your site, use a platform integration such as Shopify's, or use Tag Manager. Google recommends Tag Manager for most tag deployments.

How long until conversions show up?

Status can take up to 48 hours to update. Run a test conversion and check again the next day before changing anything.

Do I need enhanced conversions?

It is optional, but Google designed it to improve measurement accuracy using hashed first-party data. Most advertisers who collect email at checkout or on forms should consider it.

Do I need consent mode?

If you have visitors in the EEA or UK, Google's EU user consent policy applies and consent mode is how your tags pass those choices. Check with your legal adviser on what your site requires.

Rather have it built right the first time?

If your business does $25,000+ a month in revenue, apply and Mitch will review your accounts personally. Earlier than that? An ad account audit gives you a senior-level fix list you can work through yourself.
