Customer Match in Google Ads

Google Ads has quite a few interesting features not many of us are using. Some of them are buried deep down in options or are not available for all accounts, which is why not many have heard about them. Customer Match is evidently one of them.

How unpopular is it? Well, one of our PPC managers asked a Google rep about this feature, only to hear, “I’ve never heard about it – let me investigate.”

One reason for this lack of popularity is that not every account can use all of it. According to the Google Customer Match Policy, any account in good standing can use Customer Match for Observation and Exclusions. The Targeting setting is different. It needs at least 90 days of Google Ads history and more than USD $50,000 in total lifetime spend. Our Google Ads management team has also seen that Targeting can become available to an account that sits under an MCC which meets the criteria. More on that below.

How Does Customer Match Work?

Customer Match allows you to upload a list of customer email addresses or customer IDs to Google Ads. These lists can come from your CRM, email marketing platform, or other databases. Once uploaded, Google securely matches these identifiers with Google user accounts, enabling you to target ads to specific individuals.

By using this feature, you can connect with existing customers, re-engage past visitors, or target specific segments based on email addresses or customer IDs.

In short, you can export customer details from your CRM and use them in Google Ads to target those clients!

How to Find Customer Match in Google Ads

Customer Match Eligibility: What Your Account Needs

Google gives access to Customer Match in two tiers.

• Basic access: Your account (or its manager account) needs a good history of policy compliance and a good payment history. That is enough to use Customer Match for Observation and Exclusions.
• Full access: On top of that, you need at least 90 days of Google Ads history and more than USD $50,000 in total lifetime spend. If your account uses another currency, Google converts your spend to USD at the average monthly rate. Full access unlocks the Targeting setting and manual bid adjustments.

Google can also remove Customer Match access from any advertiser after repeated policy violations or abuse, so keep your lists and consent practices clean.

Observation vs Targeting: Two Ways to Use Customer Match

When you add a customer list to a campaign, Google asks how you want to use it. There are two options.

	Observation	Targeting
What it does	Does not narrow the reach of your campaign. You can still adjust bids for people on the list.	Narrows the reach of your campaign to the selected list, with the option to adjust bids.
Who can use it	Any account with good policy and payment history, including new accounts.	Accounts with 90+ days of history and over USD $50,000 lifetime spend, or accounts under an MCC that meets this.
Best for	Learning how your existing customers behave and giving the campaign a bid signal.	Showing ads only to existing customers, for example upsells and retention offers.

For a new account, Observation is the option you will get. Targeting stays out of reach until the account (or its MCC) meets the criteria above. Exclusions are also part of basic access, so you can stop ads showing to existing customers if you only want to win new ones.

Which Campaigns Can Use Customer Match?

According to Google's Customer Match help page, it is available on:

• Search campaigns
• Shopping campaigns
• Display campaigns
• YouTube (video) campaigns
• Gmail ads

Google updates which campaign types are supported from time to time, so check that page before you plan a campaign around it.

Update, October 2026: Unlocking Targeting Through an MCC

Google changes eligibility rules often, so we re-tested this again this month. We can confirm that Targeting can still be unlocked through an MCC.

Here is what we saw. A fairly new Google Ads account with minimal spend and no history could not use Targeting on its own. Once the account was linked to our MCC, Targeting became available and we could switch a campaign over to it. The screenshots below are from that account. Tap an image to open it full size.

One caveat: this has to be set up by a user who has access to the MCC account. It does not work if the user only has access to the normal (client) account. If you want to use Targeting on a young account, make the change while signed in through the MCC.

Main Benefits

Customer Match offers several significant advantages for businesses:

• Enhanced Targeting Precision: Reach customers already interested in your brand with relevant messages tailored to their needs and preferences.
• Increased Conversion Rates: Targeting familiar individuals increases conversion likelihood with personalised messages for repeat purchases, upsells, and cross-sells.
• Cost-Effective Advertising: Reduce wasted impressions and clicks by targeting specific audiences, optimising budget and ROI.
• Stronger Brand Awareness: Re-engage past customers to build brand loyalty and advocacy.

How to Implement Customer Match

To leverage Customer Match, follow these steps:

1. Pick Your Source: Google Ads connects to multiple platforms (Amazon Redshift, HubSpot, MySQL database, etc.)
2. Upload the Customer List: Upload a CSV with your customer data.
3. Create a Customer Match Campaign: Set up a new campaign or modify an existing one to target your uploaded customer list. Combine this list with other targeting options, like demographics, interests, and keywords, to refine your audience.
4. Craft Persuasive Ad Copy: Develop compelling ad copy that speaks directly to your target audience, highlighting benefits and offers relevant to their needs.
5. Monitor and Optimise: Continuously track metrics like clicks, impressions, conversions, and CPA to optimise your campaigns.
