YouTube drives more AI citations than Reddit in 2026. Four independent research firms confirmed in January 2026 that YouTube now appears in roughly 16% of AI-generated answers, compared to about 10% for Reddit. This is a reversal from mid-2025, when Reddit was the dominant social citation source for large language models.
The shift matters for any brand investing in AI search visibility. If the platforms that LLMs pull from are changing, your content strategy needs to change with them. This article breaks down the data behind the YouTube-Reddit citation flip, explains why it happened, and covers what marketing teams should do about it.
TL;DR
- YouTube now appears in 16% of AI-generated answers vs. Reddit's 10%, confirmed by four independent research firms (Bluefish, Emberos, Goodie AI, Profound).
- YouTube's share of social citations doubled from 18.9% to 39.2% between August and December 2025, while Reddit's share halved from 44.2% to 20.3%.
- Superlines first-party data across industries shows Reddit still leads in citation share: approximately 2.5x more citations than YouTube in the 30-day period ending February 16, 2026.
- The gap varies dramatically by AI platform: Perplexity cites Reddit 6.1x more than YouTube, while Google AI Overview shows near parity.
- LinkedIn is a dark horse for AI citations, with a citation share nearly matching YouTube's across tracked brands.
- Brands that optimize YouTube content for AI citation (transcripts, chapters, clear expertise signals) can tap into a growing citation channel, but should not abandon Reddit.
How did YouTube overtake Reddit as the top AI citation source?
The data comes from an Adweek exclusive report published January 26, 2026, which compiled findings from four separate research firms that independently reached the same conclusion.
Here is what each firm found:
Goodie AI analyzed 6.1 million AI citations across ChatGPT, Gemini, and Perplexity between August and December 2025. Their data showed YouTube's share of social media citations rising from 18.9% to 39.2% in just five months, while Reddit's share dropped from 44.2% to 20.3%. That is a complete inversion of the hierarchy.
Emberos found that YouTube is cited approximately 40% more often than Reddit across the three major AI platforms. Their analysis covered millions of AI-generated responses.
Profound reported that YouTube has 18 times more AI citations than Instagram and 50 times more than TikTok, making it the dominant video platform for AI citation by a wide margin.
Bluefish confirmed the overall trend, noting that YouTube's structured content format gives it a natural advantage for LLM extraction.
The market reacted to this news. Reddit's stock dropped 9.3% following the Adweek report, reflecting investor concern about the platform's declining role in AI-powered discovery.
Why are AI platforms citing YouTube more than Reddit?
This reflects how large language models process and evaluate different types of content. Three structural factors explain why YouTube gained ground.
Structured transcripts and chapter markers
YouTube videos with transcripts give LLMs clean, parseable text. When a video includes chapter markers (timestamps with descriptive titles), the AI can extract specific answers from specific sections rather than processing an entire conversation thread. This is similar to how well-structured web pages with clear headings perform better in generative engine optimization.
Reddit threads, by contrast, are conversational and unstructured. A single thread might contain dozens of opinions, jokes, tangents, and contradictions. LLMs have to work harder to identify which comments are authoritative and which are noise.
Expert attribution and authority signals
YouTube content is typically attributed to a specific creator with a track record. A video from a recognized expert in a field carries clear authority signals: subscriber count, view count, channel history, and often professional credentials mentioned in the video itself.
Reddit comments are pseudonymous. While some Reddit users build reputation within specific communities, the platform's structure makes it harder for LLMs to assess the authority of any individual comment. Bain & Company found that roughly 80% of search users now rely on AI summaries at least 40% of the time, which means LLMs are increasingly selective about which sources they trust enough to cite.
Content permanence and freshness
YouTube videos tend to remain stable after publication. A tutorial uploaded in 2024 still contains the same information in 2026. Reddit threads, however, can be edited, deleted, or buried by downvotes. The ephemeral nature of Reddit content makes it a less reliable citation source for AI systems that need to verify information across multiple crawl cycles.
What does the data show about citation trends over time?
The shift did not happen overnight. Looking at the five-month window from August to December 2025, the trend was consistent and accelerating.

The crossover point happened around October 2025. By December, YouTube had opened a nearly 19 percentage point lead. This is not a temporary fluctuation. It represents a structural change in how AI platforms weight different content sources.
For context, SearchEngineLand reported that Reddit still has 80 million weekly searchers and its Reddit Answers feature grew from 1 million to 15 million queries in a single year. Reddit is not dying as a platform. But its role as the primary social citation source for AI has been overtaken.
What does Superlines first-party data show?
To complement the external research, we analyzed citation data from our own AI search tracking platform. Superlines tracks AI citations across industries, monitoring responses from major LLM platforms including ChatGPT, Perplexity, Grok, Google AI Mode, Google AI Overview, Copilot, Mistral, and DeepSeek.
Our data from January 17 to February 16, 2026 reveals a more nuanced picture than the headline suggests.
Reddit still leads in citation share
Across all tracked industries, Reddit generated roughly 2.5x more AI citations than YouTube in the 30-day period. Reddit content also appeared across approximately 33% more unique prompts than YouTube.
This does not contradict the external research. The Adweek-cited studies measured YouTube and Reddit's share of social media citations specifically, while Superlines tracks total citation counts across diverse brand queries. The difference highlights an important nuance: YouTube may be gaining share in certain citation categories, but Reddit still produces significantly more citations in brand-related AI responses.
The gap varies dramatically by AI platform
The most striking finding is how differently each LLM treats these two platforms:
- Perplexity cites Reddit 6.1x more than YouTube, with Reddit accounting for roughly 86% of social citations on the platform. Perplexity's search-grounded approach heavily favors Reddit's discussion threads.
- Grok cites Reddit 2.3x more than YouTube, with Reddit taking about 70% of social citations. Grok is the highest-volume platform for both Reddit and YouTube citations in our dataset.
- Google AI Mode shows a narrower gap, with Reddit leading YouTube 1.4x (roughly 58% vs 42% of social citations).
- Google AI Overview is nearly equal: Reddit at roughly 52% vs YouTube at 48% of social citations. This is the closest to parity of any tracked platform.
- ChatGPT cited Reddit regularly, while YouTube did not appear among the top citation sources for ChatGPT in this period.
If you are optimizing for a specific AI platform, these differences matter. A Perplexity-focused strategy should still prioritize Reddit presence, while a Google AI Overview strategy may benefit more from YouTube investment.
LinkedIn is the surprise competitor
An unexpected finding from the Superlines data: LinkedIn's citation share nearly matches YouTube's, accounting for a comparable proportion of total social citations across tracked industries. LinkedIn appeared across a similar number of unique prompts as YouTube and was cited by multiple LLM platforms. For B2B brands especially, LinkedIn may be as strategically important as YouTube for AI search optimization.
Weekly citation trends show both platforms growing
Our weekly data shows both Reddit and YouTube citations are actually growing overall, driven by increasing AI search usage overall:
- Reddit citations grew steadily week over week: +5% (Jan 25), +24% (Feb 1), and then surged +114% (Feb 8), for a total increase of roughly 179% over the four-week period.
- YouTube citations also showed strong weekly growth, trending upward throughout the period.
Both platforms are seeing increased citation volume as AI search adoption accelerates, but Reddit's growth rate has been steeper in our dataset. The Feb 8 week saw Reddit citations nearly triple compared to the Jan 18 baseline.
How does this affect brands optimizing for AI search?
If your AI visibility strategy relies heavily on Reddit presence (posting in subreddits, building comment authority, getting mentioned in recommendation threads), you need to diversify. YouTube is now a higher-leverage channel for earning AI citations.
Here is how the citation shift changes the calculus for different content types:
Product reviews and comparisons
AI platforms frequently cite product reviews when answering purchase-intent queries. A detailed YouTube review from a recognized creator now carries more citation weight than a Reddit thread with mixed opinions. Brands that invest in YouTube creator partnerships or produce their own review-style content stand to gain more AI visibility.
How-to and tutorial content
Tutorial queries are among the most common prompts in AI search. YouTube's chapter-marked tutorials give LLMs a clean way to extract step-by-step answers. If your brand produces educational content, YouTube should be a primary distribution channel, not an afterthought.
Expert commentary and thought leadership
When AI platforms answer questions about industry trends or best practices, they increasingly cite YouTube interviews, conference talks, and expert commentary videos. This is because video content with a named expert provides stronger authority signals than anonymous forum posts.
Community discussions and niche queries
Reddit still holds an advantage for highly specific, community-driven queries. Questions like "what's the best budget laptop for college students in 2026" still pull heavily from Reddit because the platform excels at aggregating diverse user experiences. For niche, opinion-based queries, Reddit remains relevant.
What should marketing teams do about the YouTube citation shift?
The practical response depends on your current content mix and resources. Here are five specific actions ranked by impact.
1. Add transcripts and chapters to all YouTube videos
This is the lowest-effort, highest-impact change. YouTube auto-generates transcripts, but manually edited transcripts with proper formatting perform better for AI extraction. Chapter markers (timestamps with descriptive titles) help LLMs find and cite specific sections.
If you have existing YouTube content without chapters, go back and add them. This is a one-time investment that improves citation potential for your entire video library.
2. Create YouTube content that answers specific queries
Think about the prompts your target audience asks AI platforms. Then create YouTube videos that directly answer those queries. Use the query as the video title or as a chapter heading within a longer video.
For example, if your audience asks "how to track brand mentions in AI search," a YouTube video titled exactly that, with a clear transcript and chapter markers, has a strong chance of being cited by ChatGPT, Gemini, or Perplexity.
3. Optimize video descriptions for AI crawlers
Video descriptions should include a clear summary of what the video covers, key points with timestamps, and relevant links. AI crawlers process video metadata alongside transcripts, so a well-structured description reinforces the content's relevance for specific queries.
4. Cross-reference YouTube content in your written articles
When you publish a blog post or article, embed or link to related YouTube videos. This creates a citation network that AI platforms can follow. If an LLM finds your article and your YouTube video both addressing the same topic, the reinforcement increases the likelihood of citation.
This approach aligns with broader content optimization for AI search, where multiple content formats covering the same topic strengthen your overall AI visibility.
5. Monitor which platforms actually cite your content
Different AI platforms have different citation preferences. Some may favor YouTube more heavily than others. Tracking where your citations come from, broken down by platform, helps you allocate resources to the channels that drive the most AI visibility.
Does Reddit still matter for AI visibility?
Yes, but its role has changed. Reddit is no longer the default social citation source. It is now one of several platforms that AI systems draw from, and its share is declining.
Reddit's strengths remain in three areas:
Authentic user experiences: For queries where personal experience matters ("what's it like to use X product"), Reddit threads still provide the kind of first-person accounts that AI platforms value.
Niche community expertise: Subreddits dedicated to specific topics (r/homelab, r/personalfinance, r/SaaS) contain concentrated expertise that AI platforms cite for specialized queries.
Recency and volume: Reddit generates enormous volumes of fresh content daily. For time-sensitive queries, Reddit's recency advantage can outweigh YouTube's structural advantages.
The practical takeaway is not to abandon Reddit, but to stop treating it as your primary AI citation channel. A balanced approach that includes YouTube, Reddit, your own website, and third-party publications will produce the most resilient AI visibility.
How do other social platforms compare for AI citations?
YouTube and Reddit dominate the social citation landscape, but they are not the only players. Based on the Profound data from the Adweek report and Superlines first-party data across industries (January 17 to February 16, 2026):
- Reddit: Largest share of social citations in our data (~56% of tracked social platform citations), appearing across the most unique prompts (Superlines data). Approximately 10% of AI answers per external research.
- YouTube: Approximately 22% of tracked social platform citations, appearing across a wide range of unique prompts (Superlines data). Approximately 16% of AI answers per external research, with growing share of social citations.
- LinkedIn: Approximately 22% of tracked social platform citations, nearly matching YouTube’s share (Superlines data). A significant and growing source, especially for B2B queries.
- Instagram: Roughly 18x fewer citations than YouTube per Profound research.
- TikTok: Roughly 50x fewer citations than YouTube per Profound research.
- X (Twitter): Declining as a citation source.
The surprise here is LinkedIn. With citation volume nearly matching YouTube's across tracked industries, LinkedIn deserves more attention in AI visibility strategies than it currently receives, particularly for B2B companies. The gap between YouTube/Reddit/LinkedIn and other social platforms remains enormous. Instagram and TikTok are primarily visual platforms with limited text content for LLMs to extract.
For brands deciding where to invest content resources, the hierarchy based on our data is: Reddit first for citation share, YouTube second for structured content that LLMs prefer to cite, LinkedIn third for B2B queries, and other social platforms as supplementary channels.
What does the citation shift mean for the future of AI search?
The YouTube-Reddit flip signals a broader trend: AI platforms are getting better at processing structured, expert-attributed content and less reliant on crowdsourced opinions. This has three implications for the next 12 to 18 months.
Structured content wins: Content with clear formatting, expert attribution, and logical organization will continue to gain citation share. This applies to YouTube videos, well-structured articles, and any content format that makes it easy for LLMs to extract specific answers.
Authority signals matter more: As AI platforms process more content, they need better ways to filter for quality. Named experts, established channels, and verifiable credentials will carry increasing weight in citation decisions.
Multi-format strategies become essential: Brands that publish the same insights across multiple formats (video, article, podcast transcript, social post) create more citation surface area. AI platforms can find and cross-reference your content across formats, increasing the probability of citation.
The citation rate gap between top and average performers is already significant. As AI search grows, that gap will widen. Brands that adapt their content strategy to match how AI platforms actually select citations will pull further ahead.
Conclusion
The data paints a complex picture. External research from four independent firms shows YouTube overtaking Reddit in social citation share, while Superlines first-party data across industries reveals Reddit still leads in citation share with roughly 2.5x more citations than YouTube. The truth depends on what you measure and which AI platform you focus on: Perplexity cites Reddit 6.1x more than YouTube, while Google AI Overview shows near parity.
For marketing teams focused on AI search visibility, the takeaway is not to pick one platform over the other. Instead, invest in YouTube content with transcripts, chapter markers, and clear expert attribution. Maintain Reddit presence for community-driven and niche queries. And do not overlook LinkedIn, which our data shows generates nearly as many AI citations as YouTube.
Tools like Superlines can help you track which platforms and content formats drive the most AI citations for your brand, so you can allocate resources based on data rather than assumptions. Understanding where your citations come from, and how that mix is changing across different AI platforms, is the foundation of any effective AI visibility strategy.
