Ask five marketers the difference between retargeting and remarketing and you'll get five answers. Some say they are the same thing. Some say one is ads and the other is email. Google adds to the confusion by using “remarketing” for what most people call retargeting – and has since renamed its lists to “your data segments”.
The labels matter less than the jobs behind them. One job is bringing back people who showed interest but didn't act. The other is re-engaging people who already know you or bought from you. They need different audiences, messages, channels and success measures.
This guide untangles the terms, compares them side by side, and shows how to run both as one joined-up programme. If you're looking for step-by-step campaign setup in Google Ads, our separate guide to remarketing campaigns covers that in detail.
Key Takeaways
- Retargeting usually means paid ads shown to people who visited your site or engaged with your brand but didn't convert.
- Remarketing traditionally means re-engaging known contacts and past customers, often by email, to drive repeat purchases.
- Google uses “remarketing” for ad-based retargeting and now calls its audience lists “your data segments”.
- Both rely on first-party data and must respect consent and privacy rules.
- The best results come from combining them: ads for anonymous visitors, email and customer-list ads for known contacts.
Definitions in plain English
Retargeting
Retargeting shows ads to people based on something they did: visited a product page, added to cart, watched a video or opened a lead form. You usually don't know who they are – the platform does, via a tag or pixel. The aim is to finish an interrupted journey.
Remarketing
Remarketing, in its original sense, means marketing again to people you already have a relationship with: past customers, subscribers or leads. You know who they are because they gave you their email or bought from you. The aim is to deepen the relationship – repeat orders, upgrades, renewals, referrals.
How Google uses the words
Google's ad products use “remarketing” for showing ads to past visitors and app users. Its help documentation describes the purpose like this:
“Use your data to re-engage people who have previously interacted with your brand or services on mobile or desktop.”

Those segments include website visitors, app users, YouTube users and Customer Match lists (contact data you upload). So in Google's world, “remarketing” covers both jobs – which is why the terms blur.
Retargeting vs remarketing at a glance
| Retargeting | Remarketing | |
|---|---|---|
| Who you reach | Anonymous visitors and engagers who didn't convert | Known contacts: customers, subscribers, leads |
| Data source | Pixels, tags, platform engagement | CRM, email list, purchase history |
| Main channels | Display, social, video, search ads | Email, SMS, customer-list ads (Customer Match, Meta customer lists) |
| Typical goal | Complete the first conversion | Repeat purchase, upsell, renewal, win-back |
| Typical message | Reminder, social proof, objection handling, offer | New products, loyalty perks, replenishment, personal recommendations |
| Key metric | Conversion rate, CPA | Repeat rate, customer lifetime value |
| Main risk | Ad fatigue and feeling “followed” | Unsubscribes and list fatigue |
Where each one runs
- Google Ads: website and app visitor segments for Display, YouTube, Demand Gen and Search; Customer Match for known contacts. See our guide to Google Ads audiences.
- Meta (Facebook and Instagram): website custom audiences from the Pixel and Conversions API, engagement audiences, and customer list audiences. See Meta ads targeting.
- LinkedIn: website retargeting, video and lead form engagers, and uploaded contact or company lists – useful for account-based marketing.
- Email and SMS: abandoned cart, browse abandonment, post-purchase and win-back flows. Our guide to abandoned cart emails is a good starting point.
A combined funnel: which tactic for which audience
| Audience | Known or anonymous? | Best tactic | Example message |
|---|---|---|---|
| Viewed a product, left | Anonymous | Dynamic retargeting ads | “Still thinking about it? Free returns for 30 days.” |
| Added to cart, left (logged in or email captured) | Known | Cart email plus retargeting ads | “Your basket is saved – here's what other buyers said.” |
| Downloaded a guide (B2B) | Known | Nurture emails plus LinkedIn ads | Case study, then demo invitation |
| First-time customer | Known | Post-purchase email, cross-sell ads | How-to content, complementary products |
| Lapsed customer (no order in 6+ months) | Known | Win-back email, Customer Match ads | “Here's what's new since your last order.” |
How to build a joined-up programme
- Map your funnel stages. List the key actions (product view, add to cart, lead, purchase, repeat purchase) and where each is recorded.
- Get tracking right. Install tags with consent handling – see Consent Mode v2 and our Meta Pixel and Conversions API guide.
- Create audiences by intent and recency. “Cart abandoners, last 7 days” deserves a different message from “all visitors, last 90 days”.
- Exclude converters. Remove recent purchasers from first-purchase retargeting, then move them into remarketing sequences.
- Coordinate messages. Make sure email and ads tell the same story, and don't stack a discount in the ad that undercuts your email offer.
- Set frequency limits. Use frequency caps where available and refresh creative regularly.
- Measure incrementally. Retargeting often takes credit for sales that would have happened anyway. Use holdout tests or compare against a control group where possible.
Examples by business type
Seeing both tactics in a real context makes the difference clearer:
- Online store: a shopper views running shoes and leaves. Dynamic retargeting ads show the exact shoes on Instagram and YouTube for the next week. After they buy, they move into a remarketing sequence: care tips, a “time to replace your shoes” email months later, and Customer Match ads for new releases.
- Local service business: a homeowner reads a roof repair page but doesn't call. Retargeting ads with reviews and a clear phone number bring them back. After the job, remarketing asks for a review, then reminds them about an annual inspection.
- B2B software: a visitor reads the pricing page. LinkedIn and Google retargeting show a short demo video and a customer story. Once they become a trial user, remarketing switches to onboarding emails and feature announcements aimed at turning the trial into a paid plan.
In each case, retargeting is about the first “yes” and remarketing is about every “yes” after that. Budget and creative should reflect which job you are doing.
Common mistakes
- One audience for everyone. Lumping all visitors together wastes money on people who bounced in two seconds.
- Endless follow-around ads. High frequency annoys people and can harm the brand.
- Forgetting existing customers. Many businesses retarget hard but never remarket, leaving repeat revenue on the table.
- Discount addiction. Always offering a code teaches shoppers to abandon carts on purpose.
- Ignoring privacy rules. Personalised advertising needs proper consent in many regions, and some sectors – health in particular – face extra restrictions on audience building.
- Trusting platform-reported ROAS blindly. View-through conversions can overstate retargeting's real impact.

Frequently Asked Questions
Are retargeting and remarketing the same thing?
They overlap and are often used interchangeably. Retargeting usually means ads to anonymous visitors who didn't convert; remarketing traditionally means re-engaging known contacts and customers, often by email.
Why does Google call it remarketing?
Google has long used “remarketing” for showing ads to past visitors. Its audience lists are now called “your data segments” and include website visitors, app users, YouTube users and Customer Match lists.
Which is more effective?
They do different jobs. Retargeting helps convert first-time buyers; remarketing grows repeat revenue. Most businesses need both.
Do I need cookies for retargeting?
Website retargeting relies on tags and identifiers, which require consent in many regions. Customer list targeting uses first-party data you collected with permission.
How long should a retargeting window be?
Match it to your buying cycle. Short windows suit impulse purchases; longer windows suit considered or B2B purchases.
Conclusion
Don't get stuck on the vocabulary. Use retargeting to finish journeys that stalled and remarketing to keep customers coming back, and run them from one plan so messages, offers and frequency work together.
