Key Takeaways

  • Duolingo is the most-mentioned and most-recommended brand in the benchmark, with especially strong first-place placements.
  • Two conflicting claims were identified, covering the number of languages offered and the Super monthly price, and both need source verification.
  • High-citation third-party pages and Duolingo’s Spanish and French course pages were flagged for review and page brief development.
  • Observed buyer questions center on choosing a language app and learning Spanish or French, making them useful targets for content briefs.

Answer Capsule

In November 2026, Duolingo appeared in 517 of 529 AI answers included in the Language Learning Software benchmark (97.73%). It received 473 recommendations (89.41%), with 356 Top 3 placements and 234 first-place recommendations. A mention means the company appeared in an answer; a recommendation means the answer affirmatively endorsed it.

Our plan compares the company with its competitors, checks conflicting AI claims against reliable sources, and identifies website pages, third-party sources and buyer questions to address. The historical results show how the figures changed across available months. Different monthly samples limit those comparisons, and conflicting AI claims require verification before corrections are proposed.

Duolingo is the most-mentioned and most-recommended brand in this benchmark, and the gap on first-place recommendations is the striking part. Babbel appears in nearly as many answers and is shortlisted more often, yet Duolingo takes the top slot far more frequently. That suggests the answers tend to treat Duolingo as the default answer rather than one option among several.

The framing is overwhelmingly positive, with few neutral or negative mentions, so the constraint is not sentiment. The practical question for the client is whether that strength holds across different question types and services, which a scorecard can track. We would also verify the disputed claims before treating any of this as settled.

From October 2026 to November 2026, Duolingo's mention count rose from 512 to 517, while its recommendation count rose from 461 to 473. The recommendation rate was 85.53% and 89.41% respectively.

Across the recent months, mentions have stayed high while recommendations and top placements have climbed. The latest month shows the strongest recommendation and first-place readings in the series, with mentions slightly higher than the prior month. That is a favourable direction, but it is an observation, not proof that anything the company did caused it.

The monthly samples differ in size and composition, so month-to-month movement should be read as separate snapshots rather than a trend line. We would keep the scorecard running on the same basis and flag any month where the sample shifts materially, so the client can tell real movement from a comparability gap.

AI Visibility Audit

Understand exactly how LLMs are referencing your brand today and which sources are shaping those answers.

Step 1. Measure

Questions This Section Answers

  • What should the agency measure and verify first for Duolingo?

AI answers contained 2 conflicting claims about Duolingo: 0 critical, 0 high, 1 medium, 1 low. Of these, 0 were rated critical or high priority; the critical claims are included in that total. These ratings help prioritize fact-checking. They do not establish that a company or publisher made an error.

The benchmark surfaced two conflicting claims about Duolingo, one rated medium and one low. Neither is rated critical or high, so this is a modest fact-checking workload rather than a crisis. The ratings are a prioritisation aid; they do not establish that the company or any publisher got something wrong.

We would build a short visibility comparison showing where Duolingo leads and where rivals close the gap, paired with a claim list that names each disputed point, its source and the evidence needed to resolve it. That gives the client a clear order of work instead of a scattered to-do list.

Step 2. Make the website consistent

Questions This Section Answers

  • Which recorded claim differences about Duolingo should be verified before proposed page edits?

Review topic

Severity

Recorded AI claim A

Recorded AI claim B

number of languages offered

low

37+ languages

40+ languages

monthly price (Super)

medium

$7–$13/month

$6.99/month

Both columns quote AI answers, not verified company facts. Resolve the entity, date and source before deciding whether a correction is warranted; different dates can explain an apparent conflict.

The two disputed topics are the number of languages offered and the Super monthly price. Both are the kind of detail buyers check before subscribing, so an unresolved conflict is worth attention even at low severity. The recorded claims are AI answer text, not verified company facts, and different dates can explain an apparent disagreement.

We would verify each point against current primary sources, including the date each figure applies to, before proposing any page change. Where the facts hold, we would draft a conditional page brief that states the approved figure plainly; where they do not, the item stays out of the correction queue.

These pages were selected because they relate to the company in the captured answers. Their current contents still need checking before any correction request. A page linked to a conflicting claim is not necessarily its cause, and the same answer may contribute to more than one row.

The cited pages range from a major review site with heavy citation presence to forum threads and a language-resources list. Citation volume is not the same as influence, and a page linked to a conflicting claim is not necessarily its cause. Several of these pages need their current contents checked before any request is justified.

We would review the highest-appearance pages first, confirm what they currently say, and prepare evidence-backed requests only where a genuine discrepancy exists. Forum threads and aggregator lists get a lighter touch, since publisher control and correction norms differ. Ambiguous matches stay outside the queue.

Step 4. Optimize priority company pages

The company's website was cited 66 times across 26 distinct page addresses; the table shows 8 pages selected for review. Zeros in the answer columns mean no matching answers were recorded. A cited page is not automatically a page that accompanied a recommendation.

The company site is cited across many distinct pages, with the Spanish and French course pages and the homepage carrying most of the appearances. That pattern suggests course pages do real work in answers, which makes them the natural place to start page briefs. A citation does not confirm the page accompanied a recommendation, so the briefs should focus on clarity and approved facts.

We would prepare briefs for the priority pages using verified figures, the questions buyers actually ask, and a clear statement of what each course offers. Pages with no recorded answer matches are lower priority for now.

Step 5. Publish around buyer questions

These are recorded answer observations, not search volume, verified demand, or proof of missing website content.

The observed questions cluster around choosing a language app generally and learning Spanish or French specifically. Duolingo appears in every recorded answer to these questions, which makes them a useful content target rather than a gap to fill. These are answer observations, not search volume or proof of missing pages.

We would check existing coverage first, then draft buyer-question briefs for the strongest themes, such as choosing between apps and getting started with Spanish or French. Each brief would use approved facts and answer the question directly, so the page is useful to readers and to the systems summarising it.

Our 90-day action plan

Questions This Section Answers

  • How should the agency sequence the proposed Duolingo work and judge completion?

Period

Deliverable

Completion criterion

Days 1–30

Baseline scorecard, scoped fact-review register and page/source shortlist

Each record has an owner, evidence requirement and review status

Days 31–60

Approved page briefs and justified publisher requests

Separate confirmed edits, no-change decisions, requests and responses

Days 61–90

Buyer-content briefs and a fresh scorecard

Record work completed separately from measured answer outcomes and comparability limits

The first month establishes the baseline scorecard, a scoped fact-review list and a shortlist of pages and sources, each with an owner and a review status. The second month turns verified findings into approved page briefs and justified publisher requests, with confirmed edits, no-change decisions and responses recorded separately.

The third month adds buyer-content briefs and a fresh scorecard. Completed work is reported apart from measured answer outcomes, and comparability limits are noted alongside any movement. Nothing in the plan promises a visibility gain; it promises a clear, evidenced record of what was done.

Methodology

Questions This Section Answers

  • How are Duolingo answer metrics and citation populations defined?

This report covers 2026-11. The exact dates when the original AI answers were collected have not been verified. The visibility rates use 529 answers that met the benchmark's inclusion rules. A company is recommended only when the answer both endorses it and uses positive wording. Top 3 and first-place counts are part of those recommendations, not extra recommendations.

An answer can mention or recommend several companies, so company counts cannot be added to find the number of distinct answers. The net sentiment score is positive minus negative mentions, divided by all company mentions; it describes answer wording, not customer satisfaction.

The wider citation analysis covers 800 captured answers and 5437 appearances of cited URLs. Citation appearances across all captured answers differ from the number of benchmark answers citing a page and the number that also recommend a company. The current contents of cited pages and disputed company claims still need independent verification.

The answer samples differ between months. These comparisons show how the recorded results changed; they do not establish why they changed.

The report covers a single month, and the exact collection dates for the original answers are unverified. Rates rest on the answers that met the benchmark's inclusion rules, and a company counts as recommended only when an answer endorses it with positive wording. Top placements sit inside recommendations rather than adding to them.

Answers can mention several companies, so counts cannot be summed into distinct answers. Monthly samples differ, so comparisons show what was recorded, not why it changed. Cited pages and disputed claims still need independent verification.

Our first three priorities

First, verify the two disputed claims against current primary sources, starting with the Super price because it is rated medium and buyers weigh it directly. Second, review the highest-appearance cited pages to see what they currently say before any publisher request is drafted. Third, prepare page briefs for the Spanish and French course pages and the homepage, using approved facts and the buyer questions observed in the research.

A running scorecard should sit alongside this work so the client can see whether placements hold across question types and services. Each item needs an owner and an evidence requirement, and completed work should be reported separately from measured answer outcomes.

Understanding AI search visibility.

AI search experiences create answers by pulling information from many places online and summarizing it into a single response.

What Is AI Citation Intelligence?
AI citation intelligence is the process of measuring where AI platforms source their information and how frequently a brand is mentioned or referenced in AI-generated responses. Because LLMs synthesize across multiple sources, the sites and brands that appear repeatedly tend to influence how a topic or company is framed. This practice focuses on identifying which sources shape AI outputs and tracking brand visibility across different AI systems.
What Is Citation Architecture?
Citation architecture describes the set of sources that consistently inform how AI systems talk about a brand, product, or topic. LLMs draw from websites, articles, forums, and public discussion, and the sources they rely on most often become the backbone of their answers. Building strong citation architecture means ensuring that accurate, credible, high authority sources are the ones most likely to shape the way AI tools summarize and recommend a brand.
What Is Generative Engine Optimization?
Generative engine optimization (GEO) is the practice of improving the chances that AI systems use and cite your brand or content when generating answers. While traditional SEO is centered on ranking pages in search results, GEO focuses on how LLMs retrieve, interpret, and combine information when responding to a question. The objective is to strengthen the content and sources AI systems rely on, so your brand is treated as a trusted reference in AI responses.
What Is AI Share of Voice?
AI share of voice tracks how often a brand appears in AI-generated answers compared with competitors in the same category. It reflects visibility across AI platforms such as ChatGPT, Gemini, Claude, and Perplexity. Monitoring AI share of voice helps organizations see whether AI systems consistently include and recommend their brand for key queries or whether competitor brands are showing up more often.
