Retargeting vs Remarketing: What’s the Difference & Which One to Use?

If you’re running PPC campaigns for your e-commerce brand, you’ve probably heard the terms retargeting and remarketing thrown around like they’re the same thing. And if you’ve ever found yourself secretly wondering “Wait… is remarketing the same as retargeting?”, don’t worry, you’re not alone.

I’ve worked with dozens of e-commerce founders, marketing directors, and digital leads who were using the words interchangeably in strategy calls. It’s totally understandable, even Google Ads Rep. mixes them up sometimes.

But here’s the truth: they’re not the same.

And understanding the difference can seriously level up your PPC strategy, helping you bring back more shoppers, convert more customers, and squeeze more ROI out of your ad budget.

In this guide, I’ll walk you through:

• What remarketing and retargeting actually mean (in plain English)
• How each one works for e-commerce
• When to use one over the other, or better yet, how to use both
• And a few smart tools + tips we use at Midsummer to make these strategies sing

Let’s start by clearing up the confusion.

Retargeting vs Remarketing: Key Differences Explained

What is Retargeting?

Retargeting = paid ads that follow your visitors around online

You know when you browse a product (say, a pair of red sneakers) and then you start seeing that same pair pop up in ads on Instagram, YouTube, and random news sites?
That’s retargeting in action.

In PPC, retargeting uses tracking pixels or cookies to follow users who’ve visited your site, but didn’t purchase, and then shows them ads on other platforms to bring them back.

It’s most common on:

• Google Display Network (think banner ads across news and blog sites)
• Meta Ads (Facebook + Instagram retargeting)
• YouTube Ads (video retargeting based on watch behavior or site visits)

What makes retargeting powerful is that you’re reaching people who already know your brand. They’ve seen your product. Maybe even added it to the cart. And now, you’re just giving them a friendly nudge to come back and finish what they started.

💡 Real Example: One of our skincare clients set up a dynamic product retargeting campaign on Meta, showing users the exact products they viewed. Within 4 weeks, their ROAS hit 7.4x, and 62% of the purchases came from people who first visited via organic.

What is Remarketing?

Remarketing = re-engaging past customers or leads via email or customer data

While retargeting uses behavioral data (site visits, engagement), remarketing typically uses first-party customer data, like email addresses or past purchase history, to reconnect with people you’ve already interacted with.

Common remarketing tactics include:

• Win-back emails to customers who haven’t purchased in a while
• Upsell/cross-sell campaigns for complementary products
• Email flows for subscribers who haven’t converted
• Ad audiences built from CRM or email lists (e.g., uploading a customer list to Google or Meta)

It’s more common in:

• Email marketing platforms like Klaviyo or Mailchimp
• Customer match ads on Google, Meta, and LinkedIn
• CRM integrations that sync customer segments with ad audiences

📌 It’s all about known users, people who’ve given you their email, made a purchase, or subscribed to your list. You’re not “tracking” them with cookies; you’re reactivating them with value.

So… Is Remarketing the Same as Retargeting?

Not exactly, and this is where things get tricky.

In practice, Google Ads uses the word “remarketing” to refer to both. Which is why the confusion sticks around.

Here’s how we explain it to our clients:

So no, remarketing is not the same as retargeting, but they’re both parts of a smart re-engagement strategy. And when you know the difference, you can actually use them together to build a full-funnel machine.

Which Strategy Works Best for Your eCommerce Brand?

I’ve worked with brands selling everything from minimalist cookware to luxury skincare, and here’s one thing they all have in common: not everyone buys on the first visit. Some need time. Some need reminders. Some just need a little nudge.

That’s exactly where retargeting and remarketing come in.

But how do you know which to use, and when?
Let’s break it down with real-world e-commerce scenarios.

When to Use Retargeting

Retargeting works best for bringing back “window shoppers”, people who’ve shown interest but haven’t committed.

Here’s when it shines:

• Abandoned cart campaigns: Someone added a product to their cart but didn’t check out. Retargeting ads can show them the exact product with a reminder (or incentive).
• Product viewers who didn’t buy: A customer browsed your site, maybe even multiple pages, but left. Retarget them with dynamic product ads.
• Social engagers: Someone liked or saved your Instagram Reel, but didn’t click through? Retarget them with a tailored ad on Meta or Stories.
• New visitors from ads or SEO: If they landed on your site but didn’t convert, a retargeting ad can bring them back and increase your ROI from that first touchpoint.

🧠 Pro tip: Retargeting works best in the mid-funnel. These are people who are almost there. You don’t need to educate them, just convince them.

When to Use Remarketing

Remarketing is ideal for reconnecting with people who already know you, and giving them a reason to come back.

Best use cases include:

• Win-back campaigns: Haven’t seen a customer in 90 days? Send a targeted email with “We miss you” and a product recommendation or discount.
• Upsell/cross-sell flows: Did they buy a shampoo? Recommend the matching conditioner. Bought sunglasses? Offer a matching case or cleaning kit.
• Loyalty programs and exclusive offers: Use email or custom audiences to show VIP-only campaigns.
• Cart abandoners with emails: If you captured their email, don’t just retarget with ads. Send a sequence of recovery emails that complement the ad strategy.

📌 Unlike retargeting, which happens mostly in ads, remarketing is often driven by email and owned data. That makes it powerful (and cost-efficient).

💡 At Midsummer, we use Klaviyo + Meta to sync segments. One fashion brand reactivated 17% of “dormant” customers in 30 days using a combo of email remarketing and retargeted Instagram Stories.

Funnel Stage Alignment: Retargeting vs. Remarketing

Let’s zoom out for a second and map these tactics to the buyer journey.

The Real Power? Using Both Together.

This is where things get really good.
Because retargeting and remarketing don’t compete, they complement.

By using retargeting for intent-based behaviors (cart views, product clicks) and remarketing for lifecycle-based actions (past purchases, email interactions), you create a full-funnel re-engagement engine.

Here’s a simple example flow we use:

1. 👀 Site visitor browses product → gets retargeted with dynamic ads
2. 🛒 Abandons cart → receives cart recovery email (if email was captured)
3. 🧠 Doesn’t convert? → Follow-up retargeting ad with offer
4. ✅ Converts → moved to remarketing upsell flow (email + ad)
5. 📉 Lapses for 90+ days → enters win-back campaign via email and CRM-based ads

💡 One of our premium homeware clients ran a setup like this and increased customer LTV by 28% in just 2 months, without spending more on top-of-funnel traffic.

To sum it up?

• Use retargeting to bring back shoppers who are thinking about buying
  
• Use remarketing to re-engage customers who already know and trust your brand
  
• Use both together to build relationships, not just clicks

Retargeting vs Remarketing: Final Thoughts and How to Take Action

If you’ve made it this far, you probably already know more than most marketers about the difference between remarketing and retargeting. But more importantly, you now understand how to use them.

Let’s recap the key takeaways.

Retargeting and Remarketing Are Not the Same, But They Work Better Together

• Retargeting focuses on re-engaging people who’ve visited your site but didn’t buy, often using paid ads.
• Remarketing focuses on reactivating people who’ve already bought or subscribed, often through email or customer lists.

And yes, they overlap. Especially in platforms like Google Ads, where the terms are sometimes used interchangeably. But strategically? They play different roles in the customer journey.

Where retargeting brings back the curious browser, remarketing nurtures the relationship and builds lifetime value.

If you only use one, you’re leaving money on the table.
If you use both, in sync, with smart segmentation and consistent messaging, that’s where the magic happens.

What to Do Next

If you’re ready to roll up your sleeves and apply this to your eCommerce brand, here’s where to start:

1. Audit your current setup
   Are you running both retargeting and remarketing? Are your messages aligned? Is your segmentation sharp enough?
2. Fix the gaps
   Add exclusion rules, segment by behavior and value, refresh your ad creatives, and align your offers across email and ads.
3. Track what matters
   Focus on metrics that reflect business impact: conversion rate, cost per acquisition, and customer lifetime value.
4. Experiment and evolve
   Try new formats, like dynamic product ads, win-back flows, or loyalty-based campaigns, and test consistently.
