Since my last post about advertising on Duolingo, a lot has changed. What started as light ad integration has grown into a full-fledged advertising platform. Yes, Duolingo has officially committed to ads and it’s no longer just an experiment or a small revenue stream. Despite some initial backlash from loyal users, ads are now a core part of the Duolingo experience.
Today, users see ads after every lesson in the mobile app and display ads run while they’re learning online. Whether you love it or hate it, one thing’s clear: Duolingo advertising is in full swing and it’s opening new doors for marketers who want to reach a highly engaged, global audience.
So, if you’re thinking about advertising on Duolingo, here’s everything you need to know about what’s available in 2025 and how you can make the most of it.
Duolingo’s User Growth and Why It Matters
Before diving into the ad options, it’s important to understand Duolingo’s scale. As of 2025, the platform boasts over 110 million monthly active users, proving that the right messaging on Duolingo can drive a huge impact.
These users are more than just numbers; they are highly engaged. Duolingo’s gamified, streak-based model keeps learners coming back daily and that’s a goldmine for advertisers. Whether you’re promoting an app, a service, or a brand, you’re reaching an attentive audience that’s willing to spend time on a platform they trust.
Advertising Options on Duolingo in 2025
Now that Duolingo has embraced advertising, here are the top ways you can reach users on the platform:
1. Google Display Network (GDN)
Since Duolingo works closely with Google, using the Google Display Network remains one of the most straightforward ways to advertise on both Duolingo’s mobile app and website.
If you’re already running display ads through Google, this is a seamless addition. Just be sure to add Duolingo to your preferred placements. With Google’s smart bidding strategies and audience targeting, your campaigns can be tailored to high-intent users, like students, travelers, professionals, or parents.
2. Facebook Audience Network
If your marketing strategy leans heavily into Facebook, you’re in luck. Facebook expanded its Audience Network to include mobile applications years ago and Duolingo is now one of its premium partners.
That means your Facebook or Instagram ads can now appear right after a Duolingo lesson, an ideal time when users are focused and receptive. You can also use AdRoll, Facebook’s partner platform, for wider distribution across apps, including Duolingo.
This is a smart way to extend your Facebook ad reach beyond the newsfeed without having to change much about your existing creative or strategy.
3. Google App Campaigns (Formerly Universal App Campaigns)
If your goal is driving app installs, the updated Google App Campaigns are your best bet.
These campaigns are practically plug-and-play: just upload your copy, creatives and budget and Google handles the rest, placing your app ads on Duolingo (among other high-performing channels). With advanced machine learning, Google tests and optimizes for the best performance, helping you get the most out of every dollar spent.
Also, with Duolingo’s growing mobile user base, this is a perfect channel for targeting a younger, app-savvy demographic.
4. Sponsorship Takeovers – High-Impact Branding
Here’s the big one.
If you’re ready to go all-in, Duolingo now offers sponsorship opportunities for brands willing to make a splash. A $250,000 investment gives you a 7-day “takeover” of the Duolingo mobile app, meaning your brand will be seen every time a user interacts with the platform during that window.
It’s bold, powerful and not for every business. But for companies launching a new product, hosting a major event, or making a brand statement, the visibility is unmatched. Think of it as a digital billboard—except people are staring at it intently, every single day, multiple times a day.
Just make sure the campaign justifies the spend. Test the waters with smaller campaigns first to measure how Duolingo performs against other channels like Meta or Google Ads.
A Smarter, AI-Powered Duolingo = Smarter Ads
Duolingo is no longer just gamified; it’s AI-fied. The company recently rolled out advanced machine learning models to serve smarter, more personalized ads. Using tools like BigQuery ML, Duolingo now predicts which ad format is most likely to perform best for each user.
That means that as an advertiser, your ad dollars go further. The platform is designed to reduce noise, avoid banner blindness and improve click-through rates, all while ensuring a smooth experience for learners.
Plus, Duolingo has launched new premium features like AI-powered video conversations (e.g., “Call with Lily”), giving brands new ways to interact with users in immersive environments.
Should You Advertise on Duolingo?
Let’s be honest; Duolingo might not be for everyone. But if your target audience includes:
- Language learners
- International students
- Digital nomads
- Young professionals
- EdTech consumers
- Parents and children
Then Duolingo is an advertising goldmine.
The key is to start small, test your ad performance and compare it with other platforms. If you find success, you’ll know you’re ready for a bigger investment, maybe even a sponsorship takeover.
Duolingo for the Next Campaign?
Duolingo advertising is more than a trend, it’s a legitimate marketing channel. With a massive, active user base and smart integrations across Google and Meta, it’s a new frontier for modern marketers.
