Busuu

Busuu is a subscription language-learning app founded in 2008 and acquired by Chegg in 2022. It teaches 14 languages (Spanish, French, German, Italian, Portuguese, English, Japanese, Chinese, Korean, Arabic, Turkish, Polish, Dutch, Russian) through short mobile-friendly lessons structured around CEFR levels A1-C1, mixing vocabulary drills, grammar explanations, listening exercises, and AI-assisted speaking practice. The free tier gives access to basic vocabulary and a few lessons per language; Premium (roughly USD 6.99-14.99 per month depending on term, with annual and lifetime plans) unlocks offline mode, grammar review, vocabulary trainer, live 1-on-1 lessons with tutors, personalised study plans, and official McGraw-Hill language certificates. Busuu reports more than 120 million registered users across web and mobile.

The consumer audience is adult self-learners and university students preparing for travel, work relocation, or language certification, usually comparing Busuu against Duolingo (gamified, free-first), Babbel (podcast/grammar-focused), Rosetta Stone, and Pimsleur. A separate Busuu for Business product targets HR and L&D teams and is sold through the business.busuu.com partnership channel rather than the CJ affiliate feed. Affiliate content that converts tends to be language-learning app comparisons, language-specific course guides (best app for Spanish, best app for Japanese), and CEFR preparation posts. Busuu's native-speaker Conversations feature and McGraw-Hill certificates are the usual differentiators for review content, alongside the typical Duolingo-vs-Busuu comparison.

Busuu's affiliate program is managed through CJ Affiliate (Commission Junction, advertiser cid 5386858). Publishers apply via the public busuu.com/en/partners page, which routes into CJ's publisher signup, or existing CJ publishers can apply directly from inside the CJ dashboard. Busuu reviews applications (typically a few business days), checking that the publisher site is legitimate language-learning or education content. Approved publishers get banners, text links, deeplinks to specific language landing pages, and CJ's standard reporting, product feed, and coupon-code assets. Busuu is also syndicated through FlexOffers and VigLink for publishers who prefer those networks, with commission ranges of 8-20% reported depending on network tier.

Commission is 10% per qualifying new Premium subscription on the base CJ feed, with a 30-day click-to-subscription cookie window. Commissions validate through CJ's standard locking cycle (roughly one month after action posting) to filter out refunds and trial cancellations, and pay on CJ's net-20 monthly cycle via direct deposit, check, or Payoneer, subject to CJ's USD 50 and USD 100 minimum thresholds. Self-referrals, existing Busuu customers re-subscribing, and coupon-site traffic outside of Busuu's approved promo calendar are excluded. Busuu for Business deals are routed through business.busuu.com/partnerships and sit outside the consumer affiliate program.
