What is Google Ads Retargeting?

Google Ads retargeting, sometimes called remarketing, is a feature within Google Ads that lets you show ads to users who’ve previously interacted with your business. These users might have visited your website, watched your videos on YouTube, or used your mobile app. With a small piece of tracking code (called a remarketing tag), you can track these visitors and later serve them relevant ads when they browse the Google Display Network, search on Google, watch YouTube, or check their Gmail.

Why is this so powerful? Because you’re not targeting cold prospects—you’re re-engaging warm leads who already know your brand. That’s a much shorter and more cost-effective path to conversion.

Why Use Remarketing in Google Ads?

There are several reasons why Google Ads retargeting is a top-performing strategy:

  • Increased Conversion Rates: Users who see retargeted ads are more likely to return and convert than first-time visitors.

  • Improved ROI: Since you're focusing your budget on people who’ve already expressed interest, your cost per acquisition tends to be lower.

  • Stronger Brand Recall: Showing up across platforms keeps your brand front and center.

  • Highly Customizable: You can tailor your messages to specific user behaviors—like cart abandonment, video views, or page visits.

This makes retargeting ideal for ecommerce brands, service-based businesses, local shops, and content creators alike.

Types of Retargeting in Google Ads

Here’s a breakdown of the different ways you can use retargeting in Google Ads:

  1. Standard Remarketing
    Serve ads to users who’ve visited your website as they browse the Google Display Network.

  2. Dynamic Remarketing
    Show users personalized ads based on the specific products or services they viewed. Especially powerful for ecommerce businesses using a product feed.

  3. Remarketing Lists for Search Ads (RLSA)
    Customize your search ad bids and copy for users who’ve previously visited your site and are now searching on Google again.

  4. Video Remarketing
    Target viewers who interacted with your YouTube videos or channel.

  5. Customer List Remarketing
    Upload customer data (emails, phone numbers), and show ads to those users if they're logged into Google.

  6. App Remarketing
    Reconnect with users who have previously interacted with your mobile app.

How to Set Up a Google Ads Retargeting Campaign

Setting up remarketing is straightforward if you follow these steps:

1. Install the Remarketing Tag

Log in to Google Ads, go to “Tools & Settings,” and select “Audience Manager.” From there, generate your remarketing tag and either add it manually to your website or use Google Tag Manager.

2. Build Your Audience Lists

Segment your users based on their behaviour—such as product page viewers, cart abandoners, blog readers, or video watchers.

3. Create Your Campaign

Choose your campaign type—Display, Search, YouTube, or Performance Max—and apply your retargeting audience list in the Audience section.

4. Launch and Optimise

Once live, monitor performance metrics like cost per click, conversion rate, and frequency. Continuously optimize your creative and audience segments for better results.

What Makes Google Ads Retargeting More Effective Than Other Platforms?

When comparing retargeting capabilities across advertising platforms, here’s what sets Google Ads apart:

  • Wider Reach: Google Ads retargeting can appear across the Display Network (over 2 million websites), YouTube, Gmail, and Google Search—giving you access to nearly the entire internet.

  • Search-Based Retargeting: Only Google allows you to retarget people based on their search intent with RLSA (Remarketing Lists for Search Ads). Facebook and LinkedIn don’t offer this feature.

  • YouTube Integration: Google lets you build custom audiences from users who’ve engaged with your YouTube channel or videos—a feature not available on most other platforms.

  • Dynamic Remarketing at Scale: You can automatically generate ads using product feeds in Google Merchant Center, allowing you to retarget shoppers with the exact items they previously viewed.

  • Lower Minimums: Remarketing on Google Display Network requires just 100 active users in your audience list (and 1,000 for Search)—making it accessible even for small businesses.

Best Practices for Running High-Converting Retargeting Campaigns

To get the most out of your remarketing campaigns, follow these strategies:

  • Segment Audiences by Behavior: Don’t target everyone the same way. Someone who visited a blog post should get a different message than someone who abandoned a cart.

  • Use Frequency Capping: Prevent ad fatigue by limiting how often your ads are shown to the same person per day.

  • Exclude Converters: Ensure that those who’ve already taken action aren’t seeing unnecessary ads, which saves budget and avoids annoyance.

  • Refresh Ad Creatives Frequently: Change up your messaging every few weeks to keep it fresh and relevant.

  • Test Display and YouTube Together: Don’t limit your retargeting to banners—many users engage better with video content, especially mid-funnel.

Real-World Example: Dynamic Remarketing for an Ecommerce Brand

Let’s say you run a Shopify store. A user lands on your site, browses a few products, but doesn’t buy. With Google dynamic remarketing, the next time they open YouTube or browse news sites, they’ll see ads showing the exact products they viewed, complete with pricing, reviews, and a CTA.

That level of personalization drives them back with high intent—leading to lower acquisition costs and a better return on ad spend.

Final Thoughts

Google Ads retargeting isn’t just a marketing tactic—it’s an essential part of any serious digital strategy. Whether you’re looking to close more ecommerce sales, generate leads, or keep your brand top-of-mind, remarketing allows you to capitalize on every interaction your audience has with your business.

By tailoring your message based on user behavior and showing up across Google's powerful ecosystem—Display, Search, YouTube, Gmail—you stay relevant and persuasive without needing a huge budget.

If you’ve invested time and money into driving traffic, it only makes sense to make the most of every visit. That’s exactly what retargeting helps you do.
