It is an effective tool for advertisers as they get great results from it. According to Wordstream, it can match around 50.40% of your email list to users who can see your ads.

Google Customer Match : How it works

Google customer match

Google Customer Match is an effective tool that can be used to create a group of users that converts more.  Most advertisers think that to do this, it’s necessary to upload a file containing your existing customers’ contact information such as email address, name, phone numbers and mailing addresses into Google ads. Then create a campaign to target your customers from the file you uploaded.

This is actually not the only way to do this, and later in this article, you’ll see another method that allows you to completely automate this process.

Anyway, Google is able to match the customers’ information to users in its database to determine who can see the ads. If any of the customer’s data you uploaded matches a Google user, the customer will be added to your Customer Match audience. 

When the customers sign in to their Google account, they will see your ads as they use the Google search engine, YouTube, Gmail, and the Google Display Network. You can use the Customer Match Audience in your Ads and Google Shopping campaigns, YouTube and Gmail.

For example, if you sell Nissan cars. The keyword “Nissan cars” is too expensive for you to target because it is broad and has lots of competition. In fact, there are 1,420,000,000 search results for the keyword on Google. Using Google Customer Match, you can create an ad targeting your previous buyers searching for “Nissan cars”. The cost may not be lower but the interest is higher. Existing buyers convert more. The conversion rate for repeat customers is about 1.5 percentage points higher.

  1. Examples of audiences you can target with the Google Customer Match are:
  2. On the Google Search Network and Google Shopping, you can modify your ad campaign based on the information you have about your customers’ activities.
  3. On Gmail, you can target your ads to your existing customers or similar audiences using a personalized ad that displays at the top of Gmail inbox tabs.
  4. On YouTube, you can target new audiences, by first targeting existing audiences that have similar attributes to your most valuable customers.
  5. On Display, you can target your existing customers or similar audiences with personalized ads.

Benefits of using Google Customer Match

  1. Using the Google Customer Match ensures that your messages don’t end up in your audience spam boxes. With it, you are sure that your audience will see your ads and messages without using their Gmail inboxes. That means it cannot end up in the spam folder nor can they use auto-thrashing for it. As long as they are still on your email list, your messages and ads will get to them.
  2. Google Customer Match ensures that your advertising reaches people on different properties such as Google search, YouTube, Shopping and Gmail. Your subscribers can see your ads on those channels.
  3. Google Customer Match gives you a wider reach.  Because of its different properties, you can reach out to a much bigger audience and get lots of opportunities to acquire new customers for your business.

How to use Google Customer Match in your marketing strategies

Google Customer Match allows you to create a customer match audience which includes email addresses, physical addresses, and phone numbers and upload them into your Google AdWords to target your prospects in Search, Shopping, Gmail and YouTube campaigns.  

Below are 5 ways you can use Google Customer Match in your marketing strategies.

1.   Google Customer Match: To move prospects down the sales funnel

Google Customer Match is an effective tool you can use to move your prospects further down the sales funnel until they become paying customers. To do this, upload different email lists with customers segmented by their stages in the buying cycle. Create specific adverts to move them through the sales funnel.

For instance, you can create an audience of people who have downloaded your e-book or white paper and show them ads that promotes your case study. This will encourage them to move down the sales funnel stages.

2.   Google Customer Match: To make mid and low funnel prospects convert

Mid to low funnel prospects are sometimes difficult to convert. They can engage with your business by attending your webinars, completing a free trial and chat with your sales rep, but finds it difficult to purchase from you. This is the time to use the Google Customer Match to help them convert. 

To do this, bid on keywords that will make you appear at the top position. Your ads will appear at the top and it will keep you at the top of their minds. When you are creating ads for this group of prospects, ensure you don’t use generic ads. You can conduct a survey to find out why people are not ready to purchase your products. Then, create ads that address their sales objections directly.

This was what Wordstream did when they faced the same problem. They created a survey to ask prospects why they did not purchase their products. Most of them said that they find their software difficult to use. So, Wordstream created ads that will enable prospects to learn how to use their software for free.

3.   Google Customer Match: To sell more to your existing customers

Google Customer Match is not only for getting prospects to buy from you but also to encourage existing customers to make more purchases. The truth is, it is easier to retain existing customers than to acquire new customers. Wordstream analyzed data from their RLSA (Remarketing Lists for Search Ads) campaigns which allows them to target past buyers. They discovered that past customers convert 400% higher than new customers.

Apart from increasing conversions, targeting existing customers will also help to increase your average revenue per customer. 

For example, if you sell a one-time product such as an automobile or a house, you can use Customer Match to cross-sell complementary products. Here, you would segment your lists by the car brand purchased and customize your ads to show the corresponding item. Second, you can serve them ads notifying them of new models of the car and other sales promotions. Lastly, you can create exclusive offers for your existing customers to get them to buy more from you.

4.   Google Customer Match : To make account-based marketing more effective

One of Google Customer Match features is to enable you to target prospects based on their email addresses. This feature makes it even more effective to use account-based marketing. Instead of wasting money on ads, you can focus on targeting specific people within a specific company that you plan to reach.

You can then target these people by their account size, market size and other factors you deem relevant to the campaign.  For instance, you can specifically target customers who spend at least 2k per month on your product. You can then create a customer list of these users and increase your bids when the customers search for terms relating to your product.

5.   Google Customer Match: To target users across devices

Google Customer Match unlike remarketing enables you to target customers on all devices such as Mobile, Tablet or Laptop computer. 

With remarketing, you can lose users when they switch between devices. 

Therefore, Google Customer Match is very efficient, especially with 90% of users using different devices to carry out tasks online.

Similar audiences are the audience that looks like your existing audience from your customer emails, websites, etc. They practically shared the same interests with your audience. Similar audiences in Google Customer Match are the same as the Facebook Lookalike audiences. It helps businesses to reach new prospects. According to Google, similar audiences can boost performance by up to 60% more impressions, 48% more clicks, and 41% more conversions.

If you have a pixel-based remarketing list of at least 500 cookies or a customer match list with at least 1000 emails that Google recommended, a similar audience is automatically generated for you. A similar audience based on the customer match audiences is available for Search, YouTube, Gmail, and Display.
