Remarketing brings back visitors who left without buying. Here's how Google Ads remarketing works and how to set it up to recover lost conversions.
Why Remarketing Works
First-time visitors rarely convert. Research consistently shows that 95–98% of e-commerce visitors leave without purchasing, and the average customer touches a site 3–5 times before buying. Remarketing keeps you visible during that decision window.
The conversion rate for remarketing audiences is typically 3–5× higher than for cold prospecting traffic, at a significantly lower cost per click — because these users already know who you are.
Audience Types in Google Ads
Website visitors: Anyone who visited your site in the past 30, 90, or 180 days. The most basic remarketing audience. Segment by page visited to separate people who browsed the homepage from those who reached the checkout.
Cart abandoners: Users who added to cart but didn’t complete a purchase. Highest intent segment. Worth bidding aggressively on this audience.
Past purchasers: Existing customers. Use for upselling, cross-selling, or subscription renewals. Exclude this list from your prospecting campaigns if repeat purchase isn’t your goal.
Customer match: Upload a list of email addresses. Google matches them to logged-in users. Useful for re-engaging a lapsed customer base or excluding existing customers from prospecting.
Campaign Types for Remarketing
Display remarketing: Banner ads across Google’s Display Network (websites, apps, YouTube). Best for keeping your brand visible during the consideration phase. Use responsive display ads and let Google test combinations of your headlines, images, and descriptions.
Search remarketing (RLSA): Adjust your bids on search campaigns based on whether the user has visited your site before. You can bid higher for cart abandoners searching for your product category, or show different ad copy to warm audiences.
YouTube remarketing: Show video ads to people who visited specific pages. Effective for products that benefit from demonstration or for re-engaging users who started the checkout process.
Audience Sizes and the 1,000-User Minimum
Google requires a minimum of 1,000 users in a remarketing list before it activates. If your site gets fewer than 5,000–10,000 monthly visitors, your lists will be too small to be effective. In that case, focus ad budget on prospecting to build traffic before setting up remarketing.
Ad Copy for Remarketing
Don’t run the same generic ad to everyone. Cart abandoners respond to urgency and reassurance: stock availability, delivery speed, return policy. Product viewers respond to social proof: reviews, ratings, how many people bought. Keep remarketing copy specific to where the user dropped off in your funnel.
In Short
- Remarketing converts 3–5× better than prospecting at lower cost
- Segment audiences by behaviour: cart abandoners, product viewers, past buyers
- Use RLSA to apply remarketing logic to Search campaigns without separate campaigns
- Need 1,000+ users per list minimum — focus on driving traffic first if your site is new
