Reddit is expanding its AI visibility and citations in non-English markets through machine-translated pages. On Google’s AI products, between 40% and 73% of Reddit citations in markets like Sweden and Norway now point to Reddit’s own machine-translated versions of English threads, not local-language content.
If you publish in any of those markets, that shift is already affecting which sources appear next to yours, or instead of yours, in AI-generated answers. The language barrier that once kept English-language content from dominating local results is functionally gone on Google.
To understand how far this goes, we analyzed 64.77 million Reddit citations across 20 countries and four AI engines: ChatGPT, Google AI Overview, Google AI Mode, and Gemini. A citation here means one Reddit link shown as a source in one AI-generated answer. Of those 64.77 million, 3.7 million carried Reddit's ?tl= translation parameter, meaning the engine surfaced a translated page rather than the original thread.

The parameter everyone knows but few are watching
Reddit machine-translates its own threads and publishes the results at URLs carrying a ?tl= parameter. The translation is Reddit's; the AI search engines decide whether to cite it:
reddit.com/r/Meditation/comments/.../?tl=de → German
reddit.com/r/Meditation/comments/.../?tl=tr → Turkish
When an AI engine answers a question, its retrieval system surfaces pages and cites what it surfaced. If the citation carries ?tl=, the LLM served the translated version of a Reddit thread rather than the original. TSo the share of Reddit citations carrying ?tl= is a proxy for one specific behavior: how often each engine serves translated Reddit content. It can’t tell us whether that behavior sits in the model, the grounding engine, or the index, but it does tell us what reached the user.
What we measured
We analyzed 64M+ Reddit citations between March 1 and June 10, 2026, across 20 different countries and four AI sources: ChatGPT, Google AI Overview, Google AI Mode, and Gemini. 3,699,577 Reddit citations carried ?tl=. That’s 5.71% or roughly one in eighteen Reddit links shown to users led to a translated page rather than the original. If one answer cites three Reddit threads, we count three citations. June is an incomplete month, so we use daily averages for it.
Finding 1: ChatGPT’s translated Reddit citations dropped to near zero
The two biggest engines moved in opposite directions in May 2026. ChatGPT's share of Reddit citations pointing to translated pages dropped from 6.14% in April to 0.66% in May. In April, one in sixteen Reddit citations ChatGPT showed was a translated page; a month later, one in 150. Google kept citing Reddit's translations at scale.
ChatGPT's ?tl= share of Reddit citations, month by month:
Month | ChatGPT |
|---|---|
March 2026 | 3.93% |
April, 2026 | 6.14% |
May, 2026 | 0.66% |
June, 1–10 , 2026// | 0.30% |
Each percentage is the share of ChatGPT's Reddit citations that month that pointed to a translated page. A drop from 6.14% to 0.66% in one month does not look like noise, and the decrease was consistent in all countries: in Germany from 18.06% to 1.54%, in Sweden from 20.51% to 1.62%. For German users that means almost one in five Reddit links was translated in April, and one in sixty-five in May.
Something changed on OpenAI's side around late April or early May 2026. We are deliberately careful about where: it could be the model, the grounding engine, or the index it retrieves from. Daily data should pinpoint the exact week, and we will publish that follow-up. The behavior change itself is evident in the data, and not a hypothesis.
Finding 2: Google cites Reddit's translations at industrial scale
As mentioned, Google's AI products went the other way. From March to June, 2026, Google AI Overview served ?tl= URLs in roughly 8 to 11% of its Reddit citations, and Google AI Mode in 10 to 14%.
In non-English markets, the rates are striking. In Germany, 52% of the Reddit threads Google AI Overview cited were translated versions: more than half of every Reddit citation it showed to German users. In Sweden and Norway, it’s over 70%. In Spain, Google AI Mode hit 72% in early June. Each figure is that engine's share of its own Reddit citations in that market..
Gemini barely surfaces translated Reddit at all, with just under 1% of its Reddit citations in most months. And Perplexity, which we checked separately, is a structural zero. Across the entire period it never cited a single ?tl= URL.
Finding 3: The market split is clean
Across the 20 countries in this dataset, two clear groups emerge. In English-speaking markets (US, UK, AU, IN), translated citations stay under 1% of Reddit citations. In non-English markets (SE, NO, BR, PL, IT, MX, ES, DE), they run between 24% and 42%.
The same split holds inside each engine. The table below shows each engine’s translated Reddit citation share by market, across all months combined:
Market | Google AI Overview | Google AI Mode | ChatGPT |
|---|---|---|---|
Sweden | 71.6% | 65.4% | 10.1% |
Norway | 73.0% | 59.3% | 12.4% |
Poland | 71.7% | 54.9% | 9.0% |
Spain | 68.4% | 61.2% | 7.1% |
Italy | 65.4% | 53.5% | 9.1% |
Brazil | 57.2% | 47.8% | 17.6% |
Mexico | 54.5% | 56.6% | 11.5% |
Germany | 52.2% | 40.7% | 7.3% |
Gemini has meaningful volume in only two of these markets, at 6.1% in Germany and 26.1% in Mexico, and follows the same Google pattern in both. Across non-English markets, both Google products consistently show the highest translated citation rates. ChatGPT stays under 18% even before its May change. Germany is among the largest translation markets in the dataset, so we took a closer look.
Finding 4: In Germany, translated Reddit dominates commercial queries
We classified the translated Reddit citations served for German-market prompts by subreddit and topic. One note before the numbers: every percentage in this section is a share of those translated citations only, not of all Reddit citations. Two things stand out.
First, this is not happening at the fringes of AI search. The translated threads sit in the commercial heart of the web: bags and fashion at 13.0%, tech hardware at 12.7%, audio and smart home at 11.6%, gaming at 10.7%, automotive and EVs at 9.6%, business software at 9.5%. The most cited thread titles read like a retail catalog: "Best college backpack." "What are the best brands of refrigerators in Germany?" "Which soundbar should I buy?" (Those are Reddit thread titles, not customer prompts.) These are the buying-intent queries that product publishers, review sites, and retailers built their businesses on.
Second, the single biggest category, at 16.9%, is German daily life itself. A German user asks which German supermarket has the best prices. Google’s citation is an English-language thread from r/AskGermany, where expats compare ALDI, Lidl, REWE, and Penny, served in Reddit's machine-translated German version. The question was local as was the topic, and the German-language web has covered it for decades. The citation went to Reddit anyway.
Category | Share | What the cited threads cover |
|---|---|---|
Germany and local life | 16.9% | Cheapest supermarket, insurance warnings, banking apps |
Bags and fashion | 13.0% | Best college backpack, fountain pens, watches |
Tech hardware | 12.7% | PC builds, laptops for architects, tablets for students |
Audio and smart home | 11.6% | Soundbars, earbuds, robot vacuums |
Gaming | 10.7% | Which MMORPGs are still alive in 2026 |
Automotive and EVs | 9.6% | EVs without a home charger, e-bikes, which car to buy |
Business and SaaS | 9.5% | Sysadmin tooling, AI agents, Deel vs Rippling |
Citations can concentrate heavily around single threads. One recommendation thread can collect five figures of citations in four months, meaning one URL appears as a source in tens of thousands of AI answers. One product-authenticity thread briefly dominated an entire retail category in May. At that scale, a single thread can shape what an entire product category looks like in AI-generated answers.
What this means for international content
The language barrier that once kept English-language content from dominating local AI results is gone on Google's AI surfaces. The entire English-speaking Reddit now reaches your customers in their own language, translated by Reddit and cited by Google.
The engines don’t all behave the same way, though. The same German question can pull translated English Reddit threads on Google AI Mode and the original English threads on ChatGPT. If you track AI visibility in one engine and assume the others behave the same way, this data from May shows how wide that gap can get.
Key takeaway: The language barrier is gone, but only on Google
In non-English markets, 40% to 73% of Reddit citations on Google’s AI answers now point to machine-translated English threads. The language barrier that once protected local-language content in those results is functionally gone.
The engines don't agree on this, though, and the gap is widening. ChatGPT cut its translated Reddit citation share from 6.14% to 0.30% in six weeks. Gemini and Perplexity barely touch translated pages at all. Which engine you track determines what picture you see.
The citations flowing to translated Reddit sit in the commercial heart of the web: backpacks, refrigerators, soundbars, cars, software. Measure your citation share per engine and per market, and watch how often translated Reddit appears next to you, or instead of you.
We will keep publishing as the data moves. ChatGPT's pullback shows how fast this picture can change, in a single month, in every market at once. That is exactly why it is worth watching.
