Reddit Says Google's AI Mode Is Cutting Its Search Traffic

Reddit reported its third-quarter 2026 earnings on October 29, 2026, posting revenue growth and a swing to profit, but the headline that followed the company around for days afterward was about traffic, not profit. In its shareholder letter and on the earnings call, Reddit said search referral traffic had fallen meaningfully during the quarter, and CEO Steve Huffman pinned much of the blame on Google's AI Mode, the search feature that answers queries directly instead of linking out. This article covers what Reddit actually disclosed, what's confirmed against the company's own SEC filing, what remains Reddit's word alone, and what it means for anyone who depends on search traffic.

What Reddit actually disclosed

Reddit's Q3 2026 numbers, filed with the SEC as an exhibit to an 8-K and published as a shareholder letter, show a business that is still growing fast on paper. Revenue reached $895 million, up 53% year over year. Net income was $283 million, with diluted earnings per share of $1.40. Adjusted EBITDA came in at $402 million, 45% of revenue and up 70% year over year. Daily active uniques, Reddit's term for daily visitors, averaged 130.3 million, up 12% year over year, and weekly active uniques reached 515.2 million, up 16%. During the quarter, Reddit also repurchased about 670,000 shares for $100 million at an average price of $149.81, and the company was added to the S&P 500 index.

Underneath those headline numbers, though, Reddit flagged a geographic split that it said points to a specific cause. US daily active uniques fell 2% year over year even as international daily active uniques grew 24%. Reddit attributed the US softness largely to a decline in search referral traffic, the visits that start with someone typing a query into Google and clicking through to a Reddit thread in the results.

Huffman's comments, and what Google isn't disputing

On the earnings call, Huffman went further than the written letter, saying plainly that Google's AI Mode "does not drive traffic" to Reddit, or, as far as he knows, to anyone else. AI Mode is the search experience where Google answers a query directly inside the search results page, often by summarizing content pulled from sites like Reddit, rather than sending the searcher to a list of links to click through. Huffman added a detail that matters for how to read the complaint: "Google is crawling us as hard as ever." In other words, Reddit isn't accusing Google of blocking or de-indexing its content. Google's crawlers are still reading every thread. The change, as Reddit describes it, is downstream: Google increasingly uses that crawled content to generate an answer on the search page itself, so fewer of those reads turn into an actual click to reddit.com.

Reddit separately said it suspects a second, unrelated factor is also hurting its traffic outside the US: a change in how Google ranks machine-translated content, which Reddit uses heavily to make its largely English-language discussion threads show up in search results in other languages.

What's confirmed, and what's still just Reddit's word

The financial results, the DAUq and WAUq figures, the share buyback and the S&P 500 addition are confirmed by Reddit's own SEC 8-K exhibit, a legal filing with civil and criminal liability for material misstatements, which makes them about as solid as a public company's self-reported numbers get. The 1-million-plus weekly referral drop and the Q4 double-digit DAUq warning are also Reddit's own disclosed figures, repeated across the shareholder letter PDF and coverage from outlets including Search Engine Journal and eMarketer.

What is not independently confirmed is the causal claim at the center of the story: that Google's AI Mode specifically, as opposed to AI Overviews, general search algorithm changes, seasonal effects or Reddit's own product decisions, is the primary driver of the US referral decline. That attribution comes entirely from Reddit's own management on an earnings call and in a letter written to reassure shareholders, not from an audited study or from Google. Google has not published a response confirming or disputing Reddit's framing in any of the sources reviewed for this article. Readers should treat the dollar-and-user figures as reliable public-company disclosures and the "AI Mode did this" explanation as Reddit's interpretation of its own data, which is a different thing.

Why this matters beyond Reddit

Reddit is an unusually good test case because so much of its organic traffic has historically arrived exactly the way Huffman described: someone searches a product name or an error message, Google surfaces a Reddit thread, and the user clicks through. If that pathway is narrowing even for a site as deeply indexed as Reddit, it's a warning sign for any publisher, forum, blog or ecommerce site that built its audience the same way. AI Mode and AI Overviews can answer "is Product X good" or "how do I fix this error" using text pulled from exactly these sites, without sending a click back. For Google, the tension is between keeping searchers on Google longer, which AI Mode does, and keeping the broader open web financially healthy enough to keep producing the content Google's answers are built from. Reddit's numbers are one of the first big, public, dollar-denominated data points in that debate, even hedged as they are.

Who is affected

The most exposed group is publishers and community sites whose traffic is concentrated in the US and skews toward informational, "how do I" or "is this good" queries, the exact query types AI Mode is built to answer directly. SEO professionals and content teams face a harder forecasting problem, since a metric they've relied on for two decades, organic search clicks, may now understate how many people actually saw their content through an AI summary. Reddit's own users are affected less directly: nothing changes about using Reddit day to day, though the company's push toward a logged-in-only test outside the US means some visitors in those markets will eventually need an account to browse, where today they might not.

What changes for readers and site owners right now

For an ordinary reader, nothing changes immediately. For anyone running a website that depends on Google referrals, the practical takeaway is that a single quarter of data from one large, well-indexed platform is now public evidence that the "search click" metric can move independently of how much Google's systems are actually using your content. That's a reason to look at this now rather than wait for your own analytics to show a dip.

Cost and availability

There is no product, price or plan tied to this story, Reddit's traffic figures are a byproduct of a standard quarterly earnings disclosure, not a launch. On availability: Reddit's data shows the decline is concentrated in the US, where daily active uniques fell 2% year over year, while international daily active uniques grew 24% in the same quarter. The logged-in-only test Reddit announced is explicitly scoped to select markets outside the United States in Q4 2026, so it does not apply to Reddit's US user base yet.

What happens next

Two dated milestones are worth tracking. First, Reddit's Q4 2026 results, due early in 2026's successor year on Reddit's usual quarterly cadence, will show whether daily active uniques actually fell by the low-double-digit percentage the company warned about, or whether the decline leveled off. Second, the logged-in-only pilot outside the US, set to begin in Q4 2026, will be an early signal of whether Reddit can rebuild a traffic base that doesn't depend on a Google search click at all. Reddit's stock dropped sharply the day after the October 29 call and letter, a sign that investors are already pricing in more uncertainty than the revenue and profit numbers alone would suggest.

Our take: doing the math on a 1-million-click drop

Reddit's own number, roughly 1 million or more fewer weekly search referrals in October compared with earlier in the quarter, sounds small next to 515 million weekly active uniques. It isn't, once you look at where it falls. Reddit's weekly active uniques grew 16% year over year, yet the company is warning that total daily active uniques could still drop by a low-double-digit percentage in Q4. A low-double-digit percentage of roughly 130 million DAUq is somewhere between 13 million and 20 million fewer average daily visitors, a reminder that growth in one channel (international, up 24%) can mask a steep enough decline in another (US search referrals) to flip the overall trend negative. The lesson isn't really about Reddit's scale. It's that a platform with some of the best search visibility on the internet is telling its own shareholders, in a legal filing, that an increasing share of the queries answered about it never turn into a visit. If that's happening to Reddit, it's almost certainly happening at a smaller, harder-to-notice scale to sites with far less search equity to spare.

If your site leans on Google for traffic, here's a practical checklist worth running this week, not after your own numbers start sliding:

• Separate "informational" from "transactional" pages in your analytics. AI Mode and AI Overviews hit "what is X" and "how do I fix Y" queries hardest. If those pages make up most of your traffic, you're more exposed than a site built on product or service pages people still need to click through to use.
• Build a direct or logged-in audience, not just a search-dependent one. Reddit's own answer is a logged-in-only test. For a smaller site, that translates to an email list, an app, a membership, or anything that gets a reader to come back without re-searching.
• Diversify discovery channels now. Newsletter, X/social, YouTube, Discord or community referrals don't replace search volume one for one, but they're the channels least likely to be disrupted by how one company's AI product summarizes your content.
• Track impressions versus clicks in Google Search Console separately, monthly. A rising impressions-to-click gap on informational queries is the earliest warning sign that AI Overviews or AI Mode are answering on your behalf without sending a visitor.
• Make the content worth clicking through for, not just worth summarizing. Original data, a worked example, a tool, or a comparison a one-paragraph AI answer can't replicate gives a searcher a reason to still click, even when a summary is available.
• Don't panic on a single quarter of data. Reddit's own letter hedges its causal claim, and so should you, one company's earnings call is a data point, not proof that search traffic is dying everywhere at once.
