What is Remarketing?
Remarketing (also called retargeting) is a search engine marketing strategy that shows targeted ads to people who have previously visited your website or interacted with your brand. It works by placing a small piece of tracking code on your site that follows visitors as they browse the web, allowing you to serve them relevant ads on other websites, in search results, and across social media.
The power of remarketing lies in a simple truth: people who have already shown interest in your business are far more likely to convert than cold audiences. On average, remarketing ads achieve 2-3 times higher conversion rates than standard display advertising.
How Remarketing Works
- Install tracking code: Add the Google Ads remarketing tag (or pixel) to your website
- Build audience lists: The tag collects anonymous visitor data and builds segmented audience lists
- Create targeted campaigns: Design ads specifically for each remarketing audience
- Serve ads: When people in your lists browse the web, search, or use apps, they see your targeted ads
- Convert: Familiar with your brand, these users are more likely to return and complete a purchase or action
Types of Remarketing
Standard Remarketing (Display)
Shows banner ads to past visitors as they browse websites and apps in the Google Display Network, which reaches over 90% of internet users. Best for maintaining brand awareness and gently nudging visitors back.
Search Remarketing (RLSA)
Remarketing Lists for Search Ads (RLSA) lets you customize your search ad campaigns for people who have previously visited your site. You can bid more aggressively or show different ads when past visitors search for your keywords again.
Dynamic Remarketing
Takes personalization further by showing ads that feature the specific products or services a visitor viewed on your website. For example, if someone browsed red running shoes on your e-commerce site, they will see an ad featuring those exact shoes. This is extremely effective for e-commerce.
Video Remarketing
Targets users who have interacted with your YouTube videos or channel. You can show them ads on YouTube and across the Display Network. Effective for brands with strong video content.
Customer List Remarketing
Upload your customer email lists to Google Ads to target existing customers or leads with tailored ads across Search, YouTube, and Gmail. Great for upselling, cross-selling, and re-engaging lapsed customers.
Building Effective Remarketing Audiences
Not all past visitors are equal. Segment your audiences based on behavior for more relevant messaging:
| Audience Segment | Description | Strategy |
|---|---|---|
| All Visitors | Everyone who visited your site | General brand awareness ads |
| Product Viewers | Visitors who viewed specific products | Dynamic ads showing the products they viewed |
| Cart Abandoners | Users who added items to cart but did not purchase | Urgency-driven ads, discount offers |
| Past Converters | People who already purchased | Cross-sell, upsell, loyalty offers |
| High-Value Pages | Visitors who viewed pricing or demo pages | Targeted conversion-focused messaging |
| Time-Based | Visitors from the last 7, 30, 60, or 90 days | Adjust messaging urgency based on recency |
Remarketing Best Practices
Frequency Capping
Limit how often your ads appear to the same person. Showing an ad 3-5 times per day per user is a reasonable cap. Too many impressions create ad fatigue and can damage brand perception.
Membership Duration
Set audience list durations based on your sales cycle. A 30-day window works for impulse purchases, while 90-180 days may be appropriate for high-consideration B2B services. Shorter windows generally produce higher conversion rates.
Tailored Messaging
Do not show the same generic ad to every past visitor. Customize your message based on where users were in the funnel:
- Awareness stage: Highlight your value proposition and differentiators
- Consideration stage: Share case studies, reviews, or comparisons
- Decision stage: Offer incentives — discounts, free trials, free shipping
- Post-purchase: Suggest related products or encourage reviews
Creative Refresh
Update your remarketing ad creative every 2-4 weeks. Ad fatigue sets in quickly when the same person sees the same ad repeatedly. Rotate fresh images, headlines, and offers to maintain engagement.
Burn Pixels
Place a "burn pixel" on your conversion confirmation page. This automatically removes users who have already converted from your remarketing audience, ensuring you do not waste budget advertising to people who have already taken the desired action.
Remarketing Performance Benchmarks
| Metric | Remarketing | Standard Display |
|---|---|---|
| Click-Through Rate | 0.7% - 1.0% | 0.07% - 0.1% |
| Conversion Rate | 2% - 4% | 0.5% - 1% |
| Cost Per Click | $0.25 - $0.60 | $0.50 - $1.00 |
| Cost Per Acquisition | Typically 50% lower than non-remarketing | Baseline |
