Remarketing

Learn more

Remarketing is a marketing strategy used to re-engage people who have previously interacted with a business, website, app, advertisement, social media profile, or offer. It can reach users who viewed a product, started an order, downloaded a resource, watched a video, or purchased from the company in the past.

A remarketing campaign may remind people about an offer, encourage them to complete an interrupted process, generate repeat purchases, promote complementary products, or maintain contact with prospects who were not ready to buy during their first visit.

How does remarketing work?

Remarketing uses information about a person’s previous interaction with a business. This information may be collected through advertising tags, cookies, app identifiers, events sent to advertising platforms, social media engagement, or data that customers have provided directly to the company.

A typical remarketing process involves:

a person visiting a website, using an app, or interacting with a brand through another channel;
recording an action such as viewing a product, adding an item to the cart, or submitting a form;
adding the person to an appropriate audience segment;
launching a campaign for that segment;
showing ads across supported websites, apps, search results, social media platforms, or video services;
measuring subsequent actions, including a return visit and a completed conversion.

Not every visit results in a person being added to a remarketing audience. Consent choices, privacy settings, tracking prevention, browser restrictions, tag configuration, and the advertising platform’s ability to match available data can all affect audience coverage.

Remarketing vs. retargeting

The terms remarketing and retargeting are often used interchangeably. Both describe efforts to reconnect with people who have previously interacted with a business.

Under a narrower definition, retargeting usually refers to paid advertising based on a person’s activity on a website or in an app. Remarketing may have a broader meaning that also includes customer lists, email campaigns, marketing automation, and other communication with previous prospects or customers.

There is no universally accepted boundary between the two terms. Advertising platforms, agencies, and industry publications may use different terminology. In practice, defining the data source, audience, communication channel, and campaign objective is more important than choosing one label over the other.

What are the main types of remarketing?

Remarketing can be categorized by its data source, advertising channel, or the way the message is personalized.

Common types include:

website visitor remarketing;
mobile app remarketing;
dynamic remarketing;
customer list remarketing;
social media engagement remarketing;
video remarketing;
search remarketing;
email remarketing;
cross-channel remarketing.

Several approaches can be combined into one customer journey. Someone might view a product in an online store, later see a dynamic social media ad, and then receive an email reminding them about the items in their cart.

Website visitor remarketing

Website remarketing reaches people who visited a site and met specified conditions. A business does not need to show the same ad to every visitor. Dividing users according to their behavior can produce more relevant campaigns.

Audiences may include people who:

visited any page on the website;
browsed a particular category;
viewed a specific product or service;
spent a defined amount of time on the site;
visited multiple pages;
started completing a form;
added a product to the cart;
started checkout but did not place an order;
downloaded a catalog or another resource;
completed a purchase;
did not complete the primary conversion.

Audience rules should reflect the actual decision-making process. A person who read one educational article is usually at a different stage than someone who checked the price, added a product to the cart, and started the payment process.

What is dynamic remarketing?

Dynamic remarketing automatically adapts an ad to the products, services, or offers a person previously viewed. Instead of showing one generic ad to everyone, the system can use information from a product catalog or data feed.

A dynamic ad may include:

an image of the viewed product;
the product or service name;
the current price;
information about a promotion;
similar or complementary products;
a direct link to the relevant page.

In e-commerce, the system can connect a product identifier sent by an advertising tag with the corresponding item in a catalog. The identifiers used by the website, event tracking, and product feed therefore need to match.

Dynamic remarketing is not limited to retail. It can also support catalogs of hotels, flights, real estate, vehicles, courses, job openings, and other structured service offerings.

Customer list remarketing

A business can build audiences from its own customer data, such as email addresses or phone numbers provided directly by customers. The advertising platform attempts to match the submitted information with its user accounts.

Customer list audiences may be used to:

reactivate inactive customers;
announce a new offer;
cross-sell complementary products;
renew services or subscriptions;
promote a loyalty program;
exclude current customers from acquisition campaigns;
deliver different messages to different customer segments.

Customer data should come from an appropriate source and be used in accordance with applicable laws, disclosures provided to users, and the platform’s policies. Hashing or encrypting information before it is uploaded does not automatically remove data protection obligations.

Engagement-based remarketing

A remarketing audience does not always have to originate from a company’s website. Social media and video platforms can create audiences from interactions that take place directly within their environments.

A campaign may reach people who:

watched a video or a specified portion of it;
reacted to a post or advertisement;
visited the company’s profile;
saved a post;
opened a lead form;
started a conversation with the business;
attended an online event;
interacted with a product catalog.

These audiences can be useful when prospects discover a business through social media but do not immediately visit its website.

Remarketing in Google Ads

In Google Ads, information about people who have interacted with a business can be used across different campaign types and placements. Google currently refers to many of these audiences as segments based on the advertiser’s own data.

Audience sources may include:

website visitors;
app users;
customers matched through an uploaded list;
people who engaged with a YouTube channel or its content;
conversion and behavioral data from appropriately connected services.

A segment may be used for targeting, observing the performance of a particular group, adjusting bids, or giving automated systems signals about valuable audiences. The exact options depend on the campaign type and the platform’s current capabilities.

Remarketing in Meta Ads

Meta’s advertising system allows businesses to build Custom Audiences from website data, app activity, customer lists, and engagement across Meta technologies. Campaigns can reach people using platforms such as Facebook and Instagram.

Remarketing audience sources may include:

events recorded by the Meta Pixel;
events sent through the Conversions API;
activity within an app;
a customer list;
interactions with a profile, ad, video, or lead form;
activity involving a product catalog.

Facebook Ads and Instagram Ads can use shared data sources and audiences. Sending events from a server can improve measurement continuity and data quality, but it does not eliminate privacy requirements, the need for an appropriate basis for processing, or the obligation to respect user choices.

Remarketing for e-commerce

In e-commerce, remarketing can support multiple stages before a purchase as well as post-purchase communication.

Common scenarios include:

reminding a shopper about a viewed product;
presenting other products from the same category;
recovering abandoned carts;
reaching people who started checkout;
promoting a product that is back in stock;
communicating a price change;
cross-selling complementary products;
encouraging another purchase of a consumable product;
reactivating customers who have not purchased recently;
excluding recent buyers from ads for the same product.

Campaign performance depends on factors such as catalog accuracy, consistent product identifiers, image quality, inventory availability, pricing, shipping terms, and the experience after someone clicks an ad.

Showing a product that is no longer available or directing the shopper to a broken page can waste advertising spend and reduce trust.

Remarketing for service businesses and B2B sales

Remarketing is not limited to online stores. Service and B2B purchases may require several interactions, consultations, comparisons, and approval from multiple stakeholders.

A campaign may remind prospects about:

a particular service;
scheduling a consultation;
a report or catalog they downloaded;
a webinar;
a case study;
an application deadline;
requesting an estimate;
a solution to a problem they previously researched.

In B2B marketing, a short audience membership period may not reflect the actual sales cycle. Measurement should also extend beyond form submissions. Lead qualification, proposals, closed deals, and customer value can be evaluated using data from a CRM system.

How should remarketing audiences be segmented?

A single audience containing every website visitor is easy to create, but it does not account for differences in user intent. Segmentation allows a business to adjust its message, budget, and campaign duration according to previous behavior.

Audiences can be segmented by:

pages visited;
products or categories viewed;
events completed;
stage in the purchase funnel;
time since the last visit;
number of visits;
cart value;
purchase history;
customer type;
device;
original traffic source;
content engagement;
the customer’s value to the business.

Segments should not become so narrow that the platform cannot use them effectively or that ad delivery becomes excessively intensive and uncomfortable. Advertisers must also follow restrictions related to sensitive information and prohibited personalization practices.

Remarketing audience membership duration

Membership duration determines how long a person can remain in an audience after completing an action. It should reflect the length of the buying process, the nature of the offer, and the campaign objective.

A person who abandoned a cart containing an everyday product may be most valuable during the first few days. A decision involving a vehicle, business software, or an expensive professional service may take much longer.

A business can create separate time-based segments for recent visitors, people who engaged several weeks ago, and customers who have been inactive for months. Each segment can receive a different message.

An excessively long duration may result in ads being shown after the person’s need has disappeared. An overly short duration may end communication before the prospect has had enough time to decide.

How should a remarketing ad be tailored?

A remarketing ad should reflect the person’s previous activity and provide a reason to return. A generic message asking users to visit again may not offer enough value.

The ad may:

remind the person about a product or service;
explain a key benefit;
address a common concern;
present customer reviews;
show a relevant case study;
explain shipping, returns, or warranty terms;
invite the prospect to schedule a consultation;
present similar products;
communicate a genuine promotion;
lead to content that supports the buying decision.

The call to action should clearly describe the next step. The message also needs to match what the user finds after clicking the ad.

Where should remarketing ads send users?

A remarketing ad should not automatically send every user to the homepage. A more relevant destination may be the viewed product, shopping cart, service page, booking form, comparison page, or a dedicated landing page.

The destination should:

match the advertisement;
continue the process the user previously started;
work correctly on mobile devices;
load quickly;
display current prices and terms;
make the next action clear;
avoid forcing users to repeat unnecessary steps;
remain accessible to people using different methods of interaction.

Even a well-configured campaign cannot fix a broken form, failed payment process, unclear offer, or missing information on the website.

Remarketing ad frequency

Frequency indicates how often one person sees an advertisement during a specified period. Too few impressions may not be enough for the message to be remembered. Too many can cause ad fatigue, annoyance, and negative perceptions of the brand.

Potential signs of excessive delivery include:

rapidly increasing frequency;
a declining click-through rate;
a rising cost per result;
more negative responses to the ad;
using the same creative for an extended period;
continuing to reach users after their need has ended.

There is no single frequency limit that is appropriate for every campaign. The channel, length of the purchase cycle, number of available creatives, audience size, and intensity of other marketing activity all matter.

Exclusions in remarketing campaigns

Exclusions are as important as audience selection. They reduce unnecessary spending and help prevent irrelevant messages from being shown.

A business may exclude:

people who already completed the promoted conversion;
recent buyers of the same product;
company employees;
users who opted out of communication;
customers who already have the advertised service;
people participating in a different sales process;
users located outside the company’s service area;
audiences assigned to another campaign.

A purchase should not always end all advertising communication. A customer might receive an ad for a complementary product, onboarding resource, or next stage of a service. That communication should be handled through a separate and appropriately designed scenario.

Does remarketing require a discount?

Remarketing does not have to depend on discounts or promotional codes. A person may have left because information was missing, the timing was wrong, they had concerns about the product, they encountered a technical issue, or they needed another person’s approval.

Alternatives to a discount include:

a clearer explanation of the benefits;
an answer to a common question;
reviews and case studies;
information about secure payment;
clear shipping and return terms;
a comparison of available options;
a free consultation;
a product demonstration;
a reminder about a genuine deadline.

Consistently offering discounts to people who abandon their carts can train customers to delay purchases and unnecessarily reduce profit margins.

How is remarketing performance measured?

Campaign evaluation should not be limited to clicks. Depending on the objective, relevant metrics may include:

reach;
impressions;
frequency;
click-through rate;
cost per click;
conversion volume and conversion rate;
cost per conversion;
revenue;
profit margin;
average order value;
ROAS;
ROI;
recovered carts;
lead quality;
customer lifetime value;
view-through conversions;
assisted conversions.

Individual audience segments should be evaluated separately. A campaign targeting cart abandoners will usually perform differently from one targeting every visitor to a company’s blog.

Remarketing and conversion attribution

People in remarketing audiences already know the business and are often closer to making a decision than new prospects. Remarketing campaigns can therefore report strong results even when the ad was not the only reason a purchase occurred.

A conversion may follow organic search, a paid ad, a direct visit, an email, a conversation with a sales representative, and several remarketing impressions. Assigning all value to the last click can overlook earlier stages of the journey.

View-through conversions require particular caution. The fact that someone saw an ad before purchasing does not prove that the transaction would not have occurred without the ad.

The true incremental effect of remarketing can be evaluated through control groups, experiments, and conversion lift analysis. These research options are not equally available across every platform and campaign type.

Remarketing vs. customer acquisition

Remarketing and customer acquisition campaigns serve different purposes. Remarketing re-engages people who already know the business, while prospecting campaigns attempt to find new audiences.

An audience modeled after existing customers is not a remarketing audience if it consists of new people who have never interacted with the brand. Remarketing data can still help an advertising platform identify characteristics associated with valuable users and support new customer acquisition.

A budget dedicated entirely to remarketing does not continually create new demand. When fewer new users enter the funnel, the number of people available for re-engagement also decreases.

Remarketing and marketing automation

Advertising remarketing can work alongside a marketing automation system. A person who downloaded a resource or abandoned a cart may enter an appropriate communication sequence across several channels.

Marketing automation may use:

email;
push notifications;
text messages;
in-app communication;
tasks assigned to the sales team;
CRM status changes;
audience synchronization with advertising platforms.

Sending the same message through several channels at the same time can become intrusive. Automation should account for completed conversions, user responses, communication frequency, and opt-out preferences.

How is remarketing implemented technically?

The implementation depends on the platform, website, and campaign type. A typical process may involve:

defining campaign objectives and remarketing scenarios;
selecting the events that need to be recorded;
implementing advertising tags or app integrations;
configuring a consent management system;
creating a catalog or feed for dynamic ads;
ensuring product identifiers are consistent;
sending the required event parameters;
creating audiences and exclusions;
setting membership durations;
preparing ad creatives and landing pages;
configuring conversion tracking;
testing the complete implementation before launch.

The presence of a tag is not enough. The quality of the data it sends also needs to be tested. An incorrect product ID, a purchase recorded twice, or an event sent before required consent is obtained can produce inaccurate audiences and reports.

Remarketing, cookies, and privacy

Remarketing may involve storing identifiers, observing user activity, building advertising profiles, and transferring information to third-party platforms. Businesses need to consider the laws that apply in each market and the policies of the advertising systems they use.

In the European Union, cookies and similar technologies used for behavioral advertising generally require prior user consent. Privacy information should clearly explain the purposes, tools, types of data involved, and the method for withdrawing consent.

An appropriate implementation may require:

blocking relevant technologies until consent is obtained;
recording and respecting the user’s choice;
making consent withdrawal easy;
updating privacy and cookie disclosures;
limiting the amount of data collected;
setting appropriate retention periods;
controlling access to audiences and customer lists;
reviewing vendor agreements and settings;
deleting data the business no longer needs;
following rules related to minors and sensitive information.

A server-side integration is not a method for bypassing consent or other privacy obligations. It changes how information is transmitted, but it does not remove the need to evaluate the data’s source, purpose, and lawful use.

Remarketing and first-party data

Restrictions on third-party identifiers have increased the importance of first-party data, which is information collected directly through a company’s relationship with its customers and users.

First-party data may include:

customer and subscriber information;
purchase history;
activity within a customer account;
consent and communication preferences;
loyalty program data;
sales team interactions;
CRM statuses and customer segments.

First-party data is not automatically available for every marketing purpose. A business should control its source, quality, accuracy, consent status, and eligibility for use in a particular channel.

Limitations of remarketing

Remarketing does not include every person who visited a website or interacted with a brand. Audience size and quality can be affected by:

lack of consent for advertising cookies;
user privacy settings;
script and ad blocking;
browser and operating system restrictions;
people using multiple devices;
an inability to match available information;
incorrect event configuration;
insufficient audience size;
a short membership duration;
platform policies affecting particular industries or data categories.

The audience reported by an advertising platform may therefore differ from the total number of users who meet similar conditions in an analytics system.

Remarketing in sensitive industries

Advertising platforms restrict personalization based on information involving health, financial circumstances, beliefs, sexual orientation, and other sensitive characteristics.

Even when it is technically possible to create an audience from visits to a particular page, using that audience may violate platform policies or applicable law. Audience names, membership rules, and ad copy should not reveal or imply sensitive information about a specific person.

Advertisers should review the platform’s current policies, industry-specific restrictions, and the laws that apply in each target market before launching a campaign.

Common remarketing mistakes

Common problems include:

targeting every website visitor with the same advertisement;
failing to distinguish between stages of the purchase journey;
not excluding people who have already purchased;
advertising products that are no longer available;
using inconsistent identifiers across the website and catalog;
allowing frequency to become excessive;
using one creative for too long;
setting a membership duration that does not match the buying cycle;
sending every ad click to the homepage;
failing to adapt the message to previous activity;
building every campaign around a discount;
evaluating performance only through last-click attribution;
ignoring conversions that would have occurred without the ad;
recording events incorrectly or more than once;
activating advertising tags without accounting for consent;
sending information that the platform should not receive;
treating remarketing as a substitute for new customer acquisition.

What are the benefits of remarketing?

A well-designed remarketing program can:

keep a brand and its offer visible;
increase return visits;
recover some abandoned carts and forms;
support longer decision-making processes;
match communication to previous interests;
increase cross-selling opportunities;
reactivate existing customers;
reduce irrelevant ad delivery;
make better use of existing website traffic;
connect advertising activity with sales data.

Results still depend on the quality of the offer, data, segmentation, creative, landing page, budget, and measurement. Remarketing does not guarantee conversions and cannot create demand for a product that the audience does not want.

When should a business use remarketing?

Remarketing can be especially useful when:

customers rarely purchase during their first visit;
the business has a long sales cycle;
users frequently abandon carts or forms;
the offer requires education and comparison;
the website attracts enough users to build meaningful audiences;
the company has a valuable customer database;
repeat purchases are possible;
the business sells complementary products or services;
the brand publishes content that supports purchase decisions;
conversion tracking works correctly.

Remarketing may be less valuable when the audience is extremely small, purchases almost always happen immediately, additional communication provides no benefit to the user, or legal and platform restrictions prevent appropriate use of the available data.

How to start a remarketing campaign

A business should begin with one specific scenario instead of creating many complex audiences without sufficient data. This could be a campaign for people who viewed an important service or users who added a product to the cart without placing an order.

The next steps are:

define the campaign objective;
verify that relevant events are measured correctly;
identify the data source and required consent;
create the audience and appropriate exclusions;
match the membership duration to the decision-making process;
prepare several ad variations;
select the appropriate destination page;
define primary and supporting metrics;
monitor frequency, costs, and conversion quality;
develop more detailed segmentation as reliable results become available.

Effective remarketing is not about following a person everywhere with the same advertisement. It should deliver a relevant message at a time when it can help the person resume an interrupted process or make an informed decision.
