Retargeting vs Remarketing: What’s the Difference?

Businesses spend considerable time and money attracting visitors to their websites, promoting products, and generating leads. However, not everyone who visits a website makes a purchase or completes the desired action immediately. Some visitors compare different products, others leave because they are not ready to buy, and many simply become distracted before completing a transaction.

This is where retargeting and remarketing become important.

Both strategies help businesses reconnect with people who have previously interacted with their brands. They are used to encourage repeat visits, recover abandoned shopping carts, generate additional leads, and increase sales.

Although the terms retargeting and remarketing are sometimes used interchangeably, they can describe different approaches. Retargeting traditionally refers to reaching previous website visitors through paid advertisements. Remarketing has historically been associated with reconnecting with existing customers and prospects through email campaigns and other direct communication channels.

Modern advertising platforms sometimes use these terms differently. For example, Google Ads uses the term remarketing for audience-based advertising campaigns, including campaigns that reach previous website visitors.

Understanding the distinction helps businesses select the right tools, develop effective campaigns, and improve customer retention.

1. What Is Retargeting?

Retargeting is a digital advertising strategy that allows businesses to show advertisements to people who have previously interacted with their websites, products, applications, or other online content.

The objective is to bring these people back and encourage them to complete an action they did not perform during their previous visit.

For example, someone may visit an online electronics store, view a laptop, and leave without purchasing it. Later, while browsing another website or using a social media platform, that person may see an advertisement promoting the same laptop.

This is retargeting.

The advertisement reminds the visitor about a product they previously considered and gives the business another opportunity to generate a sale.

Retargeting is commonly used by e-commerce businesses, software companies, travel agencies, educational institutions, and professional service providers.

How retargeting works

Retargeting generally relies on audience identification and advertising technology.

A typical process involves the following steps:

1. A visitor arrives at a business website.

2. The website uses an eligible advertising tag, pixel, or other measurement technology.

3. The visitor’s interaction is recorded, subject to applicable consent and privacy requirements.

4. The advertising platform may add the visitor to an eligible audience.

5. The business creates an advertisement campaign targeting that audience.

6. The visitor may see the advertisement on participating websites, applications, or social platforms.

7. The advertisement encourages the person to return and complete a desired action.

For example, an online clothing store can create an audience of people who viewed a particular product but did not purchase it.

The store can then show eligible members of that audience an advertisement featuring the product, a related collection, or a relevant promotional offer.

Common retargeting channels

Businesses can use several advertising channels for retargeting.

• Google Display Network.

• YouTube advertising.

• Facebook and Instagram advertising.

• Other programmatic display networks.

• Selected mobile advertising environments.

• Eligible search advertising audience campaigns.

The availability of each channel depends on the advertising platform, campaign configuration, audience eligibility, and privacy restrictions.

2. What Is Remarketing?

Remarketing is a marketing strategy focused on reconnecting with people who have previously interacted with a business.

Traditionally, the term has often been associated with email marketing campaigns that target existing customers, subscribers, and prospects.

For example, an online retailer may send an email to a customer who purchased a laptop several months ago, recommending compatible accessories.

A software company may send an email to someone who registered for a free trial but never upgraded to a paid subscription.

These are examples of remarketing.

Remarketing helps businesses maintain communication with people who already know their brands. Instead of relying entirely on attracting new customers, companies can encourage previous visitors and customers to return.

How remarketing works

Remarketing usually begins with a business collecting customer or subscriber information through permitted interactions.

This may include:

• Newsletter subscriptions.

• Customer registrations.

• Previous purchases.

• Product inquiries.

• Webinar registrations.

• Free trial sign-ups.

• Previous service engagements.

• Customer support interactions.

The business can then segment its audience and send relevant messages.

For example, an online education company may divide its subscribers into groups based on the courses they have purchased or the subjects they have expressed interest in.

It can send each group information about relevant programmes, upcoming classes, new learning materials, and registration opportunities.

Common remarketing channels

Remarketing can take place through several communication channels.

Email marketing: Sending promotional messages, product recommendations, reminders, and special offers to eligible subscribers.

SMS marketing: Sending relevant messages to customers who have agreed to receive promotional text communications.

Push notifications: Sending updates and promotional messages through supported websites or applications.

Customer relationship management (CRM): Using customer information to coordinate follow-up communication and sales activities.

Advertising platforms: Using audience-based advertising to reconnect with previous visitors and customers.

The exact definition varies between marketing platforms. In particular, Google uses remarketing to describe advertising campaigns that reach people who have previously interacted with a business.

3. Retargeting vs Remarketing: Key Differences

The main distinction is the traditional marketing approach associated with each term.

Retargeting generally focuses on paid advertisements shown to previous visitors or other eligible audiences. Remarketing traditionally focuses on maintaining communication with existing prospects and customers through channels such as email.

However, both strategies share the same broad objective: bringing interested people back to a business.

The distinction is useful when planning campaigns, but businesses should recognize that modern platforms do not always follow this traditional terminology.

4. How Retargeting and Remarketing Work Together

Retargeting and remarketing do not have to operate as separate marketing activities.

Businesses can combine them to create a more coordinated customer re-engagement strategy.

Consider an online store selling computers and accessories.

A visitor arrives at the website and views a laptop but does not complete the purchase.

The business may use retargeting to show the visitor an advertisement featuring the laptop on an eligible advertising platform.

If the visitor has also subscribed to the store’s newsletter, the business may send an email highlighting product features, financing options, or compatible accessories.

The customer could then return to the website and complete the purchase.

After the purchase, the business may send additional emails about warranties, accessories, software, and customer support.

This illustrates how paid advertising and direct communication can work together.

A coordinated approach can help businesses:

• Recover abandoned shopping carts.

• Increase repeat website visits.

• Encourage product purchases.

• Generate additional inquiries.

• Improve customer retention.

• Promote related products.

• Support customer loyalty.

The important principle is that each interaction should provide a relevant reason for the person to engage with the business again.

5. Retargeting vs Remarketing: Which Channels Are Used?

The channels used depend on the campaign objective and how the business defines its strategy.

Retargeting channels

Retargeting is commonly associated with paid digital advertising.

Google Ads: Businesses can create eligible audience segments based on previous website or application interactions and use them in supported advertising campaigns.

Facebook and Instagram Ads: Meta Custom Audiences can help advertisers reach eligible people who previously interacted with their websites, applications, pages, or content.

YouTube Ads: Businesses can use eligible audience segments to reconnect with people who previously interacted with their videos or other supported content.

Programmatic advertising: Advertisers can use eligible audience data to deliver advertisements through participating websites and applications.

Search advertising: Eligible audience segments can be used in supported search campaigns to adjust targeting or bidding strategies.

Remarketing channels

Remarketing traditionally relies on direct communication and customer relationship management.

Email marketing: Businesses send newsletters, product recommendations, promotional offers, and follow-up messages.

SMS marketing: Companies communicate important offers, reminders, and updates through text messages.

Push notifications: Websites and applications send updates to subscribers who have enabled notifications.

CRM platforms: Sales and marketing teams use customer records to organize follow-ups and manage relationships.

Automated messaging: Businesses create sequences that respond to customer actions, such as registration, purchases, or abandoned transactions.

Some advertising platforms also classify audience-based paid advertisements as remarketing, so the terminology should always be interpreted within the platform being used.

6. Retargeting for E-commerce Businesses

E-commerce is one of the most common applications of retargeting.

Online shoppers frequently compare products, check prices, read reviews, and visit several stores before making a purchase.

A visitor may leave an online store without buying because they are researching alternatives or simply do not have enough time to complete the transaction.

Retargeting gives retailers another opportunity to reach eligible visitors.

Product-view retargeting

A retailer can create an audience of people who viewed specific products.

For example, a customer who viewed a smartphone may later see an advertisement featuring that device.

The advertisement can highlight relevant features, customer reviews, or a product offer.

Shopping-cart retargeting

Abandoned shopping carts represent another opportunity.

A shopper may add several products to a cart but leave before completing payment.

The business can use eligible advertising audiences to remind that person about the products.

Category-based retargeting

Businesses can also create audiences based on product categories.

Someone browsing office furniture may later receive advertisements promoting desks, chairs, storage solutions, or related products.

Cross-selling and upselling

After a purchase, a retailer may promote complementary products.

For example, someone who purchased a laptop could receive advertisements for laptop bags, wireless mice, or external storage devices.

The purpose is to encourage additional purchases without relying entirely on acquiring new customers.

7. Remarketing for Customer Retention

Remarketing is particularly valuable for businesses that depend on repeat purchases, subscriptions, and long-term customer relationships.

Acquiring a new customer can require substantial marketing expenditure. Encouraging an existing customer to return may provide another opportunity to generate revenue.

Email-based customer retention

Businesses can use email marketing to maintain relationships with previous customers.

A clothing retailer may send customers information about new collections, seasonal promotions, or products related to previous purchases.

A software company may share feature updates, tutorials, and information about additional services.

Subscription renewal campaigns

Subscription businesses can use remarketing to remind customers about upcoming renewals, account changes, or available plans.

For example, a professional software provider may contact eligible subscribers before their subscriptions expire.

Re-engagement campaigns

Some customers become inactive over time.

A business can create a campaign encouraging these customers to return by highlighting new products, improved services, or relevant offers.

Loyalty campaigns

Businesses can use remarketing to promote loyalty programmes, membership benefits, exclusive offers, and other customer retention activities.

The goal is to build a continuing relationship rather than treating every purchase as an isolated transaction.

8. Costs: Retargeting vs Remarketing

The cost of each strategy depends on the tools, channels, audience size, and campaign objectives.

Retargeting costs

Retargeting usually involves paid advertising expenditure.

Common costs include:

• Advertising impressions.

• Advertising clicks.

• Campaign management.

• Creative production.

• Tracking and measurement tools.

• Landing page development.

Display retargeting campaigns may use CPM or CPC bidding. Social media campaigns may also use different bidding and optimization models.

The actual cost depends on audience competition, campaign settings, location, and advertising quality.

One advantage is that businesses can often focus spending on people who have already demonstrated interest in their products.

However, a small retargeting audience may not provide enough scale for a large campaign.

Remarketing costs

Remarketing costs depend on the communication channels used.

Email marketing may involve monthly platform subscriptions, subscriber-based pricing, sending volume, or additional automation fees.

SMS campaigns may charge according to message volume, destination, and service provider.

CRM platforms may charge based on the number of users, customer records, features, or other subscription arrangements.

Although direct communication can be cost-efficient, businesses still need to invest in content, segmentation, automation, and campaign management.

Which is more affordable?

Email-based remarketing can be less expensive than repeatedly paying for advertising impressions or clicks, especially when a business has a well-maintained subscriber list.

However, it is not automatically cheaper in every situation. Building and maintaining a quality email list requires investment, while retargeting can reach eligible previous visitors who have not subscribed to a company’s mailing list.

The most appropriate approach depends on the audience and the value of the expected conversion.

9. Personalization: Making Retargeting and Remarketing Relevant

Personalization can improve the relevance of both strategies.

Generic advertisements and repetitive promotional emails often fail to provide a convincing reason for customers to return.

Businesses should use available information to create messages that reflect previous interactions and customer interests.

Personalization in retargeting

Retargeting campaigns can use eligible audience information to show relevant advertisements.

For example:

• Visitors who viewed a specific product can see advertisements featuring that product.

• Visitors who explored a service page can see advertisements explaining the service.

• People who completed a purchase can be excluded from advertisements promoting the same purchase.

• Visitors who viewed several products can receive advertisements featuring related collections.

Dynamic retargeting can also display products based on previous browsing activity when supported by the advertising platform and properly configured product data.

Personalization in remarketing

Email and CRM-based remarketing can use customer information to create more relevant communication.

For example, an online education company may send different messages to:

• People who registered for a course but did not attend.

• Students who completed an introductory programme.

• Customers who purchased advanced training.

• Subscribers interested in specific subjects.

This approach helps businesses avoid sending identical messages to people with different needs.

Effective personalization should be useful, transparent, and consistent with customer expectations and applicable privacy requirements.

10. Advantages of Retargeting

Retargeting offers several benefits for businesses.

Reaches people who already know the brand

Retargeting focuses on eligible people who have previously interacted with a business.

These audiences may already understand the company’s products or services, making them valuable prospects for follow-up campaigns.

Supports abandoned-cart recovery

Online retailers can reconnect with eligible shoppers who viewed products or added items to their carts without completing purchases.

Improves advertising relevance

Businesses can use previous interactions to deliver more relevant advertisements.

Supports multiple customer journey stages

Retargeting can help move people from awareness to consideration and eventually toward conversion.

Complements other advertising campaigns

Businesses can use retargeting alongside search ads, social media ads, display advertising, and video campaigns.

Helps increase conversion opportunities

Some potential customers need several interactions before making a decision. Retargeting creates additional opportunities to bring them back.

11. Disadvantages of Retargeting

Despite its benefits, retargeting has some limitations.

Audience size restrictions: Businesses need enough eligible visitors to create useful audiences. Smaller websites may have limited retargeting opportunities.

Privacy and consent requirements: Tracking and audience creation must comply with applicable laws, consent requirements, and advertising platform policies.

Advertisement fatigue: Showing the same advertisement repeatedly can irritate users and reduce engagement.

Limited reach beyond previous visitors: Traditional retargeting focuses on people who have already interacted with a business, so it does not replace customer acquisition campaigns.

Tracking limitations: Browser restrictions, consent choices, platform policies, and changes in tracking technology can reduce audience measurement and targeting capabilities.

Advertising expenditure: Businesses must continue investing in paid campaigns to maintain advertising exposure.

Companies should use frequency controls, audience exclusions, creative variations, and sensible retention periods to keep campaigns relevant.

12. Advantages of Remarketing

Remarketing provides several opportunities for businesses to strengthen customer relationships.

Encourages repeat purchases

Businesses can use relevant communication to introduce additional products and encourage customers to return.

Supports customer retention

Regular, useful communication helps maintain relationships with existing customers.

Promotes new products and services

Companies can inform previous customers about new products, updated features, and additional services.

Supports automated communication

Email marketing and CRM platforms allow businesses to create automated campaigns based on customer activity.

Improves customer education

Businesses can share tutorials, product information, helpful resources, and service updates.

Reduces dependence on new customer acquisition

A company with an engaged customer base can generate additional opportunities through existing relationships.

13. Disadvantages of Remarketing

Remarketing also presents challenges.

Requires an existing audience: Email-based remarketing generally depends on having customers, subscribers, or prospects to contact.

List quality matters: Outdated addresses and unengaged subscribers can reduce email performance.

Communication fatigue: Sending too many promotional messages can cause people to unsubscribe or ignore future communication.

Deliverability problems: Poor email practices can lead to spam filtering and reduced inbox placement.

Consent requirements: Businesses must follow applicable rules governing email, SMS, and other direct marketing channels.

Content requirements: Effective campaigns need relevant messages, suitable offers, and appropriate segmentation.

A remarketing programme should focus on providing value rather than sending repeated promotional messages without considering customer needs.

14. Retargeting vs Remarketing: Which Is Better for Different Industries?

Both strategies can support businesses across different industries, but their applications vary.

E-commerce businesses

Retargeting can help recover abandoned shopping carts and reconnect with people who viewed products.

Remarketing can encourage repeat purchases through email recommendations, loyalty offers, and product announcements.

SaaS companies

Software businesses can use retargeting to reach visitors who explored pricing pages, product demonstrations, or feature descriptions.

Remarketing can nurture free-trial users, send onboarding emails, promote advanced features, and encourage subscription upgrades.

Educational institutions

Schools and training providers can use retargeting to reconnect with people who visited programme pages but did not apply.

Remarketing can send application reminders, course information, registration announcements, and learning updates to eligible subscribers.

Travel businesses

Hotels and travel agencies can use retargeting to reach people who previously explored destinations, accommodation, or travel packages.

Remarketing can communicate booking information, seasonal promotions, and relevant travel offers to existing customers.

Professional service providers

Consulting companies, agencies, and other service providers can use retargeting to reach previous website visitors.

Remarketing can maintain communication with prospects through newsletters, follow-up messages, educational content, and service updates.

Financial and insurance businesses

Eligible companies can use carefully controlled advertising and customer communication to reconnect with people who have expressed interest in permitted products and services.

These businesses must pay particular attention to financial advertising regulations, sensitive data, consent, and platform-specific restrictions.

15. Tools Used for Retargeting and Remarketing

Choosing suitable software is important because different tools support different marketing activities.

Tools for retargeting

Google Ads: Supports audience-based advertising campaigns, including remarketing to eligible website and application visitors.

Meta Ads Manager: Allows businesses to create Custom Audiences and run advertising campaigns across eligible Meta placements.

Google Analytics 4: Helps businesses understand website interactions and can support audience creation for connected advertising products when configured appropriately.

AdRoll: Provides advertising and marketing capabilities designed to support retargeting and customer re-engagement.

Criteo: Offers commerce-focused advertising and audience solutions for eligible businesses.

The suitability of these platforms depends on advertising requirements, audience size, integrations, pricing, and geographic availability.

Tools for remarketing

Brevo: Supports email marketing, automation, and customer communication.

Mailchimp: Provides email marketing and automation capabilities for businesses.

ActiveCampaign: Offers email automation and customer relationship management features.

Klaviyo: Provides marketing automation and customer segmentation capabilities, particularly for e-commerce businesses.

HubSpot: Combines CRM, marketing automation, and customer communication tools.

Salesforce: Offers customer relationship management and marketing capabilities for businesses with more advanced customer management requirements.

Businesses should choose tools based on their actual needs rather than paying for features they will not use.

16. Privacy, Data Protection, and Customer Consent

Privacy is an important consideration when implementing retargeting and remarketing campaigns.

Both strategies can involve the use of personal information, online identifiers, customer records, or tracking technologies.

Businesses must understand the legal requirements that apply to their audiences and operations.

For example, privacy regulations such as the General Data Protection Regulation (GDPR) and applicable US state privacy laws can affect how businesses collect, process, and use personal information.

Email and SMS marketing may also be subject to separate consent and communication requirements.

Important practices include:

• Providing clear privacy information.

• Obtaining consent where legally required.

• Using advertising and analytics technologies appropriately.

• Respecting opt-out and unsubscribe requests.

• Avoiding unauthorized use of customer lists.

• Limiting unnecessary data collection.

• Applying appropriate data retention policies.

• Reviewing the policies of advertising and email service providers.

Businesses should also avoid using sensitive personal information for advertising in ways that violate applicable laws or platform policies.

A responsible re-engagement strategy respects customer choices and provides relevant communication without becoming intrusive.

17. Best Practices for Successful Retargeting and Remarketing

The effectiveness of these strategies depends on how campaigns are planned and managed.

Segment audiences carefully

Do not treat every website visitor or customer as having the same interests.

Create relevant groups based on previous interactions, purchases, or engagement.

For example, someone who viewed a product should not necessarily receive the same message as someone who completed a purchase.

Use relevant advertisements and messages

The content should reflect the audience’s previous interaction.

A person who visited a pricing page may benefit from information about product features, subscription options, or a free trial.

Control advertising frequency

Showing the same advertisement too frequently can frustrate potential customers.

Use suitable frequency controls and regularly review campaign performance.

Avoid unnecessary repetition

Businesses should not continue promoting a product to someone who has already purchased it unless there is a relevant cross-selling or repeat-purchase opportunity.

Test different offers

Test different headlines, images, calls to action, and promotional messages.

For email campaigns, compare subject lines, message formats, and sending schedules.

Maintain accurate customer data

Outdated subscriber lists, incorrect customer records, and poorly configured tracking can reduce campaign effectiveness.

Regularly review data quality and audience definitions.

Measure meaningful results

Do not judge success only by advertisement impressions, email opens, or clicks.

Track completed purchases, qualified leads, repeat revenue, customer retention, and other business outcomes.

18. Final Verdict: Retargeting vs Remarketing

Retargeting and remarketing are closely related marketing strategies designed to reconnect businesses with people who have previously interacted with their brands.

Traditionally, retargeting focuses on reaching previous website visitors through paid advertisements displayed across websites, social platforms, and other digital environments.

Remarketing traditionally focuses on reconnecting with existing prospects and customers through email marketing, SMS, CRM systems, and other direct communication channels.

However, modern advertising platforms sometimes use the term remarketing to describe audience-based advertising, so the distinction is not universal.

For e-commerce businesses, retargeting can help recover abandoned shopping carts and encourage product purchases, while remarketing can support repeat sales and customer loyalty.

For SaaS companies, retargeting can reconnect with interested website visitors, while email-based remarketing can nurture trial users and encourage subscription upgrades.

The strongest strategy often combines both approaches. Paid advertisements can bring interested visitors back to a website, while email and customer communication can maintain relationships and encourage further engagement.

Ultimately, businesses should focus on delivering relevant messages at appropriate times, respecting customer privacy, and measuring the revenue and customer value generated by their re-engagement activities.
