Best Retargeting Platforms & Companies Compared (2026)

The best retargeting platforms for most brands are Meta Ads, Google Ads, and TikTok Ads, which handle retargeting natively inside the ad networks you already use. Specialist retargeting companies like AdRoll, Criteo, and StackAdapt add cross-channel reach, dynamic product ads at scale, and programmatic inventory. LinkedIn is the go-to for B2B. Which one is right depends on your channels, catalog size, and budget.

This guide explains how retargeting works, compares the leading platforms and vendors, and shows how to choose.

What is retargeting?

Retargeting shows ads to people who have already interacted with your brand: visited your site, viewed a product, added to cart, watched a video, or engaged on social. It works because these people already know you, so they convert at a higher rate than cold audiences.

The two main mechanics:

• Pixel-based retargeting: a tracking tag (Meta Pixel, Google tag, TikTok Pixel) records site visitors and adds them to audiences automatically.
• List-based retargeting: you upload customer or lead lists (emails, phone numbers) and the platform matches them to user accounts.

Retargeting and remarketing are often used interchangeably. See remarketing vs. retargeting and the types of retargeting.

Best retargeting platforms and companies

1. Meta Ads (Facebook and Instagram)

Meta retargets website visitors, app users, video viewers, and page or profile engagers through custom audiences built from the Meta Pixel and Conversions API. E-commerce brands can run dynamic catalog ads that show each person the products they viewed.

Best for: DTC and e-commerce brands, and any brand whose customers spend time on Instagram and Facebook.

2. Google Ads

Google remarketing reaches past visitors across Search, YouTube, Display, and Gmail using the Google tag and customer lists. Retailers can use dynamic remarketing with a Merchant Center feed.

Best for: reaching high-intent visitors across search and the open web, including people who return to Google to compare options.

3. TikTok Ads

TikTok builds custom audiences from the TikTok Pixel and Events API, video engagement, and customer lists, and supports catalog-based shopping ads.

Best for: brands with younger audiences and strong short-form video creative.

4. LinkedIn Ads

LinkedIn retargets website visitors (via the Insight Tag), video viewers, and lead-form openers, and lets you layer professional filters such as job title and company.

Best for: B2B companies retargeting decision-makers.

5. AdRoll

AdRoll is a retargeting and marketing platform that runs campaigns across display, social, and email from one dashboard.

Best for: small and mid-size e-commerce brands that want cross-channel retargeting without managing each network separately.

6. Criteo

Criteo is a commerce media company known for dynamic, product-level retargeting across a large network of publishers and retailers.

Best for: retailers and marketplaces with large product catalogs.

7. StackAdapt

StackAdapt is a programmatic advertising platform (DSP) that supports retargeting across native, display, video, connected TV, and audio.

Best for: brands that want programmatic reach beyond the walled gardens.

How to choose a retargeting platform

1. Start where your audience already is. Most brands get the most retargeting value from Meta and Google first, then add TikTok or LinkedIn depending on audience.
2. Consider catalog size. Dynamic product retargeting (Meta catalog ads, Google dynamic remarketing, Criteo) matters most when you sell many SKUs.
3. Decide between native and cross-channel. Native platforms are cheapest to start. Specialists like AdRoll and StackAdapt help when you want unified cross-channel campaigns.
4. Check tracking quality. Retargeting depends on clean pixel and server-side events (Conversions API, Events API). Fix tracking before adding vendors.
5. Plan frequency and exclusions. Exclude recent purchasers and cap exposure so retargeting doesn't annoy the people closest to buying.

The overlooked lever: retargeting creative

Retargeting audiences are small, so they see the same ads often and fatigue fast. Platforms deliver the ads, but performance depends on giving warm audiences a new reason to act:

• Answer objections with testimonials, reviews, and comparison content.
• Show the product in use with demos and creator-led UGC.
• Match the funnel stage: product viewers need different messages than cart abandoners.
• Refresh often to avoid creative fatigue.

MediaNug produces UGC and performance creative for retargeting and prospecting on Meta and TikTok. If you're looking for a partner to manage the whole program, see what remarketing services include.

Frequently asked questions

What is the best retargeting platform?

For most brands, Meta Ads and Google Ads are the best starting points because they reach the most people with native retargeting tools. Add TikTok for younger audiences, LinkedIn for B2B, and specialists like AdRoll, Criteo, or StackAdapt for cross-channel or programmatic reach.

What do retargeting companies do?

Retargeting companies provide the technology or services to show ads to people who've already interacted with your brand. Some are ad platforms (Meta, Google), some are specialist vendors (AdRoll, Criteo), and some are agencies that run strategy and creative.

Is retargeting the same as remarketing?

The terms are often used interchangeably. Some marketers reserve "remarketing" for email re-engagement and "retargeting" for paid ads.

How much should I spend on retargeting?

Retargeting budgets are limited by audience size. Spend scales with the traffic you send to your site, so most brands spend far more on prospecting than on retargeting.
