How we make this list: we compare pricing pages, product documentation and public user reviews. Ratings come from G2, Capterra or Trustpilot, with the date we checked them.

We review this list regularly. Vendors can request a listing, send updated pricing or ask about featured placement.
We started with the platforms that show up most often in advertiser discussions, review sites and agency recommendations, then narrowed the list to tools that are actively sold and supported in 2026. Pricing and plan details come from each vendor's own website and pricing pages; where a vendor does not publish pricing, we say so instead of guessing. We cross-checked positioning and plan structures against public reviews on G2, Capterra, TrustRadius and SourceForge, plus advertiser discussions on Reddit, to confirm who each platform actually serves. We did not accept paid placements, and we make no claims about hands-on testing. Company-size fit mattered as much as features: a platform can be excellent and still be wrong for a five-person business.
One distinction cuts through this entire list, and understanding it will save you from a common budgeting mistake. Google Ads and Meta Ads are walled gardens: your retargeting runs inside their inventory, using their data, and you cannot take those audiences anywhere else. That is fine when your customers live on those properties, and the reach is enormous, but it means your retargeting strategy is rented from two landlords.
Everything else on this list buys the open internet. Criteo, The Trade Desk, StackAdapt, Simpli.fi, Choozle, AdRoll and ReTargeter reach users across thousands of publishers, apps and streaming services through programmatic exchanges. The practical move for most growing businesses is one walled garden plus one open-internet platform: Meta Ads for social retargeting paired with AdRoll or Criteo for the open web, for example. That way a change in one company's policies or prices never takes down your entire remarketing program at once.
Start with your monthly media spend, not the feature list. Under a few thousand dollars a month, your realistic options are AdRoll, Google Ads and Meta Ads: no minimums, self-serve setup, and audiences you can build in an afternoon. Between that level and true enterprise budgets, Criteo makes sense for retailers, and Choozle or Simpli.fi can work through agency relationships.
Above that, the enterprise DSPs earn their keep. The Trade Desk and StackAdapt justify their complexity when you are coordinating display, video, CTV and audio across markets and need independent measurement to prove it. Also weigh who will run the platform. Self-serve tools demand your time or your agency's; ReTargeter's managed service exists precisely for teams that would rather outsource that work. Finally, check the integrations that matter to you: native ecommerce connectors, CRM hooks for B2B, and cookieless identity support will matter more in 2026 than any single dashboard feature.
AdRoll, Google Ads and Meta Ads all let you start with no minimum spend, so the cheapest option depends on your audience rather than the platform fee. If your customers are on social media, start with Meta Ads. If they find you through search and YouTube, start with Google Ads. For ecommerce stores wanting product ads across the web, AdRoll is the usual starting point.
Not necessarily. Self-serve platforms like AdRoll, Google Ads and Meta Ads work with modest budgets. Enterprise DSPs like The Trade Desk and StackAdapt are a different story: they are priced and structured for large monthly spends and experienced teams. Match the platform tier to your budget instead of stretching into a tool built for bigger advertisers.
The terms are often used interchangeably. Strictly speaking, retargeting usually means serving display or social ads to past site visitors via cookies or pixels, while remarketing often refers to re-engaging past customers through email. In practice, most platforms on this list use retargeting to cover both.
Yes, and the platforms are adapting. AdRoll was an early mover on Google's Privacy Sandbox APIs, The Trade Desk built UID2 as an identity alternative, and Meta and Google use their own logged-in user data. Expect audience match rates and setup steps to keep changing through 2026, which is another reason to favor platforms investing in cookieless identity.
Most growing businesses end up with two: one walled garden (Google Ads or Meta Ads) and one open-internet platform (AdRoll, Criteo or a DSP). That combination covers the places your audience actually spends time and keeps you from depending on a single company's inventory, data and policies.
