Your AI search visibility now depends heavily on two platforms you may not think of as search: YouTube and Reddit. Ask Google, Gemini or Perplexity a buying question and the answer often leans on a video or a forum thread.
The short answer: YouTube dominates Google’s AI answers, Reddit dominates Gemini and Perplexity, and ChatGPT has moved towards official and primary sources. Your plan should follow the engines your buyers use.

The short version
- YouTube leads Google. It is the most cited site in AI Overviews.
- Reddit leads Gemini and Perplexity. Discussion threads carry real weight there.
- ChatGPT is different. Reddit and YouTube citations fell in 2026 as official sources gained.
- Plan by engine. Find out which assistants your buyers use first.
- Fix before you film. Structure your existing videos, then fill the gaps.
- Join Reddit openly. Add value, disclose who you are and never pay for praise.
What is AI search visibility?
AI search visibility is how often, and how well, your brand appears in answers from assistants such as ChatGPT, Gemini, Perplexity and Google’s AI Overviews.
It covers being named in the answer, being described accurately and having your content cited as a source. Those sources are often not your own website.
Why do YouTube and Reddit drive AI search visibility?
Three reasons stand out. First, scale. Reddit says it holds 27 billion posts and comments, with 1 billion added in the third quarter of 2026 alone, according to its Q3 2026 earnings call. YouTube holds a vast library of how to video.
Second, access. Reddit gave Google structured access to its content through its Data API in February 2024, and OpenAI followed in May 2024. Google owns YouTube outright.
Third, buyers want real opinions and demonstrations. Threads supply one, videos the other.
The shift cuts both ways. Reddit’s chief executive, Steve Huffman, said on the same call that AI Overviews and AI Mode push links down the page and “are not traffic drivers”, adding that “Google has really shifted in their relationship with the rest of the Internet.” Being cited is not the same as being clicked.
Does every AI engine cite YouTube and Reddit the same way?
No. The same two platforms rank very differently from one engine to the next.
YouTube and Reddit share of AI citations, by engine
Google’s AI Overviews lean towards video. Gemini and Perplexity lean towards Reddit. AI Mode sits in between.
| Engine | YouTube | What it tells you | |
|---|---|---|---|
| Google AI Overviews | 24.5%, ranked 1st | 18.1%, ranked 2nd | Video leads. A strong YouTube library is the clearest single lever here. |
| Google AI Mode | 17.0%, ranked 3rd | 18.1%, ranked 2nd | google.com itself leads at 23.4%. Both platforms matter about equally. |
| Perplexity | 14.2%, ranked 2nd | 24.6%, ranked 1st | Discussion first, video close behind. |
| Gemini | 6.3%, ranked 3rd | 29.9%, ranked 1st | The most Reddit heavy engine in the set. |
| Microsoft Copilot | 1.8%, ranked 13th | Not in the top 50 | Retailers and reference sites lead. Amazon has 16.1%. |
| ChatGPT | About 1 in 500 answers | About 1 in 43 answers | Down from 1 in 5 for Reddit in March 2026. Different measure, see below. |
Google, Perplexity, Gemini and Copilot rows: mention share among the top 50 cited domains, US, November 2026, from Ahrefs Brand Radar (Copilot list). ChatGPT row: share of US answers citing each site in late September 2026, from Ahrefs, 12 October 2026. The two measures are not directly comparable.
ChatGPT is the outlier. In March 2026, about 1 in 5 ChatGPT answers cited Reddit. By late September it was about 1 in 43, according to Ahrefs. YouTube fell from about 1 in 370 answers to 1 in 500.
Other trackers saw the drop too. Promptwatch data reported by Search Engine Journal showed Reddit’s share of ChatGPT search citations falling from 3.83% to 0.52% in August 2026. One tracker can misread a sudden change, so treat any single figure with care.
Ahrefs says ChatGPT is moving from sites that summarise information towards the sources that produce it, such as research bodies, regulators and brands.
How to improve AI search visibility in 7 steps
This is the order we recommend. Steps 1 to 3 tell you where to focus, steps 4 to 6 do the work and step 7 keeps it honest.
1. Map which engines your buyers use
Start with the engines, not the platforms. A plan built for Google AI Overviews looks very different from one built for Gemini or ChatGPT.
Ask sales and customer teams which assistants buyers mention. Check the AI Assistant channel in GA4 and the generative AI report in Search Console for clues.
Most UK brands will rank Google first, because AI Overviews sit on top of results people already use.
2. Check which sources each engine cites for your category
Run 20 to 30 real buyer questions through your top engines and note every source cited. You are looking for a pattern: video, threads, retailers or official sites.
If YouTube videos keep appearing for your category in Google, video is your priority. If Reddit threads dominate Perplexity or Gemini answers, community work matters more.
Our guide to how to rank on ChatGPT covers how to choose the questions worth winning.
3. Audit what YouTube and Reddit already say about you
Search both platforms for your brand, your products and your main competitors. Whatever is there today is what AI engines can find today.
On Reddit, note the subreddits where your category comes up, the common complaints and the questions nobody has answered well.
On YouTube, list the videos that rank for your category questions, whoever made them.
Reddit Pro, which is free, lets a business track keywords such as its name, products and competitors, according to Reddit.
4. Fix your YouTube back catalogue before filming anything new
Oscar Owen, our cofounder, recommends auditing the back catalogue first, because structure matters more than view counts.
Add chapters named after the questions each video answers. Write detailed descriptions, check the captions and rewrite titles the way customers actually type.
He made the point in a LinkedIn article in May 2026:
A 50,000 view video that’s structured properly will get cited more often than a 5 million view video that isn’t.
Our YouTube SEO guide and our brand channel checklist cover the details.
5. Make videos that answer buyer questions
Then fill the gaps you found in step 2. Tutorials, product demos, reviews and pricing explainers are the obvious places to start.
That matches BrightEdge data reported by Search Engine Land: YouTube citations clustered around tutorials, pricing, demos and reviews, and were less common for abstract advice.
Answer several related questions per video and chapter each one.
6. Join Reddit openly, as a brand
Set up an official, clearly named account and listen before you post. Reddit’s own playbook calls this the lurk phase.
Reddit’s rules for businesses are short: be transparent about which brand you represent, follow each community’s rules and never offer incentives for positive comments. That comes from Reddit Help.
The Reddit Pro organic playbook puts it simply: always add value, and most communities do not allow self promotion.
In practice: real answers, from a named person on the team.
7. Measure by engine and rebalance every quarter
Track your mentions and cited sources separately for each engine. Then shift effort towards the platform each engine actually rewards.
Expect movement. Ahrefs data shows Reddit, Wikipedia and YouTube all losing share in ChatGPT between March and September 2026, while official brand sites and primary sources gained.
That is a reason to keep your own site strong as well. In the same study, 75.9% of the most common single site searches ChatGPT ran pointed at a brand’s own site.
Our GEO vs SEO guide explains which parts of your existing SEO work carry over.
Example: a 90 day plan
Here is how the seven steps might look for a fictional UK cycling accessories brand we will call Larkfield.
Its prompt check showed YouTube videos in most Google answers for its category, and Reddit threads in most Perplexity answers. So it split the work between both.
| Week | Larkfield’s focus | Output |
|---|---|---|
| 1 to 2 | Engine map and source check | 30 prompts on four engines, sources logged |
| 3 to 4 | Audit YouTube and Reddit | Gap list: 12 unanswered questions |
| 5 to 8 | Back catalogue fixes | Chapters, captions and new titles on 18 old videos |
| 9 to 12 | New videos and Reddit replies | 6 tutorial videos, weekly replies in 3 subreddits |
| 13 | Retest and rebalance | Same 30 prompts, compared engine by engine |
Larkfield is a fictional brand and this plan is invented to show the format. It is not based on a real brand or client.

Frequently asked questions
Why does Google cite YouTube so often in AI answers?
Google owns YouTube, and video suits practical questions such as tutorials, demos and reviews. YouTube had 24.5% of AI Overviews citations among the top 50 sources in Ahrefs’ November 2026 data.
Is Reddit still important for AI search visibility?
Yes, on most engines. Reddit led Gemini and Perplexity in Ahrefs’ November 2026 data and was second in Google AI Overviews and AI Mode. ChatGPT is the big exception, where Reddit citations fell sharply in 2026.
Should brands post on Reddit?
Yes, if you do it openly and add value. Use a clearly named account, follow each community’s rules and answer questions rather than promoting products.
Does YouTube help with ChatGPT visibility?
Only a little, based on current data. Ahrefs found about 1 in 500 ChatGPT answers cited YouTube in late September 2026. For ChatGPT, your own site and primary sources matter more.
How long does it take to improve AI search visibility?
Give it at least a quarter before judging results. Fixing existing videos is usually faster than making new ones.
