If you’ve ever Googled “remarketing vs retargeting,” you’ve probably come away more confused than when you started. And honestly, the industry has itself to blame.
Google calls it “remarketing.” Meta calls it “retargeting.” Some agencies use both terms interchangeably. Others insist they’re completely different strategies.
Even the Wikipedia article lumps them together. Helpful.
So who’s right?
The truth is, there are genuine differences between remarketing and retargeting … but the terminology has become so muddied that you need to look past the labels and focus on what each strategy actually does, which channels it uses, and where it fits in your marketing funnel.
That’s exactly what this guide covers. No jargon wars. Just practical clarity so you can decide which approach (or combination) will actually move the needle for your business.
Why Everyone’s Confused (Including the Platforms)
Before we define anything, let’s acknowledge the elephant in the room. The marketing industry has a terminology problem with these two words.
Google Ads uses the term “remarketing” to describe showing paid display ads to people who’ve previously visited your website. By most definitions, that’s actually retargeting. But Google owns the platform, so they get to call it whatever they want.
Meta (Facebook/Instagram) uses “Custom Audiences” and “retargeting” for essentially the same thing… serving paid ads to people based on their previous interactions with your brand.
Email platforms like Mailchimp and Klaviyo use “remarketing” to describe re-engaging existing customers through email sequences based on their purchase history or behaviour.
So you’ve got one term (“remarketing”) being used to describe two very different things depending on who’s talking. No wonder everyone’s confused.
PRO TIP: Don’t get hung up on which label is “correct.”
The labels vary by platform.
What matters is understanding the underlying strategies, the channels they use, and the audiences they target. That’s what we’ll focus on.
Remarketing vs Retargeting: The Actual Difference
What Is Retargeting?
Retargeting is showing paid ads to people who’ve previously interacted with your website, app, or content… but haven’t converted yet. You don’t have their contact details. You’re reaching them through third-party ad networks based on their browsing behaviour.
How it works: a tracking pixel (a tiny piece of code) on your website tags visitors with a cookie or browser identifier. When those visitors leave your site and browse elsewhere… scrolling Instagram, reading the news, watching YouTube… your ads follow them, reminding them of what they looked at.
Retargeting channels: Google Display Network, Meta Ads (Facebook/Instagram), YouTube pre-roll, LinkedIn Ads, TikTok Ads, programmatic display networks.
The audience: Anonymous visitors.
People who’ve shown interest through their behaviour but haven’t given you their email, phone number, or any identifiable contact information.
The goal: Bring interested visitors back to convert… whether that’s a purchase, a form submission, or a sign-up.
What Is Remarketing?
Remarketing is re-engaging known contacts … people already in your database… through owned channels like email, SMS, or direct communication. You have their details because they’ve previously purchased, signed up, or provided their information.
How it works: using your CRM, email marketing platform, or customer database, you segment existing contacts based on their behaviour (purchase history, browsing activity, engagement level) and send them targeted messages designed to bring them back.
Remarketing channels: Email sequences, SMS campaigns, push notifications, direct mail, loyalty program communications.
The audience: Known contacts. People whose details you already have… past customers, email subscribers, CRM contacts.
The goal: Re-engage existing customers to drive repeat purchases, upsells, cross-sells, win-backs, and increased lifetime value.
Remarketing vs Retargeting: Side-by-Side
Put simply…
Retargeting = paid ads to anonymous visitors (behavioural data, third-party platforms).
Remarketing = direct messages to known contacts (first-party data, owned channels).
EXPERT TIP: The easiest way to remember the difference? Ask yourself: “Do I have this person’s contact details?” If yes, it’s remarketing territory. If no, it’s retargeting. The channel follows the data.
Remarketing vs Retargeting
Same goal. Different channels, data, and audiences. Here's how they compare.
When to Use Retargeting
Cart and form abandonment recovery
This is retargeting’s bread and butter.
Someone adds a product to their cart or starts filling out an enquiry form, then leaves.
Retargeting ads serve them a reminder… often featuring the exact product they were looking at… as they browse other sites or social media.
Speed matters here – serving the ad within hours of abandonment dramatically outperforms waiting days.
Re-engaging website visitors who didn’t convert
Not everyone who visits your site is ready to buy on their first visit.
Retargeting keeps your brand visible as they continue their research, compare options, and move through the consideration stage.
You’re staying top of mind without requiring them to remember your URL.
Promoting specific products or offers to interested audiences
If a visitor spent time on a particular service page or product category, retargeting lets you serve ads specifically related to what they were looking at.
Dynamic retargeting takes this further by automatically pulling the exact products they viewed into the ad creative.
Worked Example: A Sunshine Coast physio clinic gets 2,000 website visitors a month.
About 60 of those visit the “Book Online” page but don’t complete a booking.
A retargeting campaign on Meta showing a “First visit free” offer to those 60 people costs roughly $150/month in ad spend. If even 10 of them convert, at an average patient lifetime value of $1,200, that’s $12,000 in revenue from $150 in spend.
When to Use Remarketing
Win-back campaigns for lapsed customers
Post-purchase upselling and cross-selling
Loyalty and retention campaigns
Re-engagement for subscription renewals
For SaaS, membership, or subscription businesses, remarketing is how you reduce churn.
Automated email sequences triggered by usage patterns, expiry dates, or inactivity signals keep subscribers engaged before they cancel.
Worked Example: An eCommerce store selling supplements knows that a 30-day supply of protein powder runs out around day 25.
An automated remarketing email on day 23 saying “Running low? Reorder now and get 10% off” converts at 3x the rate of a generic promotional email. That’s first-party data doing the heavy lifting.
How to Set Up Retargeting and Remarketing (Platform by Platform)
Here’s the practical bit. If you’re setting these up for the first time, here’s what’s involved.
Setting up retargeting on Google Ads
Google calls it “remarketing” (yes, confusing).
In Google Ads, you create audience segments based on website visitors tracked by the Google tag.
You can target all visitors, visitors to specific pages, or visitors who started but didn’t complete a conversion. These audiences are then used in Display campaigns, YouTube campaigns, or Performance Max campaigns.
PRO TIP: Set up audience segments for your highest-intent pages first: pricing pages, contact pages, cart pages. These visitors are closest to converting and will give you the best return on retargeting spend.
