DataForSEO’s Search Insider 2026 shows a Google that looks very different from two years ago. AI Overviews now appear on 61% of the results pages DataForSEO tracks, up from 6% in September 2024. When an AI Overview appears, its citations take an estimated 42–45% of clicks. The report draws on 190 million keywords, 165 million AI answers and about 1.1 billion backlink URLs.
The report has 15 headline findings in four parts: how Google Search is changing, when AI Overviews appear, who gets cited in AI search, and which link signals go along with visibility. We’ve written a separate article on each major finding. This page summarizes all 15 and links to the full breakdowns.
We also asked six AI engines the same questions the report answers. Their answers contradicted each other, and the report itself, more often than they agreed. That gap is why we wrote this series.
Key Takeaways
- AI Overviews appeared on 61.43% of tracked US Google results in August 2026, up from 5.93% in September 2024, while featured snippets fell from 8.96% to 0.44%.
- Desktop CTR for position 1 fell from 17.83% to 7.43% between September 2025 and August 2026. Mobile position 1 fell less, from 25.17% to 20.80%.
- Commercial searches triggered AI Overviews 51.35% of the time in Q3 2026, nearly double the 26.30% of Q4 2025.
- YouTube leads Google AI Overview citations (51.9M) and Wikipedia leads ChatGPT (4.88M). 27.3% of ChatGPT answers cite no source at all, versus 0.7% of AI Overviews.
- Reddit appeared in Google’s top 10 for 32.15% of searches in Q3 2026, nearly eight times Quora’s 4.11%.
- Referring domains correlate with AI citations (Spearman 0.406 for AI Overviews, 0.377 for ChatGPT) more strongly than UGC backlinks do (0.342 and 0.314).
The report at a glance
Search Insider 2026 is DataForSEO’s annual study of how search and AI-driven discovery are changing. It combines seven datasets: organic performance from 2,000+ websites, Google results for 190.3 million keywords, AI Overview and ChatGPT answer corpora, and backlink records. Most of the search and AI data covers the US in English.
The datasets cover different periods and selections, so DataForSEO reports each result separately rather than combining them. Keep that in mind when you compare figures across sections.

How Google Search is changing
Google’s results pages changed far more than the way people search. Queries are getting slightly longer, but the big shifts are in what appears above the organic results and how many clicks the top positions still get. These four findings cover query length, CTR, click distribution and AI Overview growth.
- Queries are getting longer, mostly on desktop. The share of desktop queries with five or more words rose from 29.3% to 34.8% between September 2025 and August 2026. Mobile rose less, from 29.6% to 31.9%. Read more: Google searches are getting longer.
- Desktop CTR for top positions fell sharply. Position 1 lost 10.41 percentage points on desktop and position 2 lost 12.20, while mobile held up far better. Full table by position and device: Organic CTR by position in 2026.
- AI Overviews redistribute clicks. When an AI Overview appears, its citations take an estimated 42–45% of clicks and the top organic result’s share falls from 33–38% to 21–24%. Details by intent: AI Overview citations take 42–45% of clicks.
- AI Overviews grew tenfold. Presence rose from 5.93% to 61.43% of tracked results in two years, and videos doubled to 19.98%. Featured snippets nearly disappeared. Why other estimates range from 39% to 88%: AI Overviews now show on 61% of Google search results.
When AI Overviews appear
AI Overviews no longer stick to informational searches or to any easy-to-spot keyword type. DataForSEO compared trigger rates by search intent, search volume, keyword difficulty, cost per click and industry. Intent and industry produced the biggest differences, and in every intent and search volume group the rate rose through 2026.
- Every intent now triggers AI Overviews more often. Informational queries lead at 70.44%. Commercial queries rose from 26.30% to 51.35% in three quarters, navigational queries doubled and transactional queries more than doubled. See AI Overviews nearly doubled on commercial searches.
- Popular keywords aren’t more exposed. Keywords with 201–300 monthly searches triggered AI Overviews 58.59% of the time in Q3 2026, versus 48.62% for 601+.
- Easy keywords aren’t safer. Mid-difficulty keywords (KD 21–60) trigger AI Overviews about 65% of the time, versus 60.64% for KD 1–20 and 53.76% for KD 81–100.
- Expensive keywords aren’t immune. Keywords costing $5+ per click trigger AI Overviews 49.55% of the time, nearly the same as the 50.54% for $0–$0.25. Findings 6 to 8 are covered in easy, low-volume keywords aren’t safe from AI Overviews.
- Industry matters most. Health leads at 69.68% and Finance follows at 68.80%, while Real Estate sits at 22.27%, a gap of more than 47 points. Full ranking: AI Overviews by industry.

Who gets cited in AI search
Google AI Overviews and ChatGPT cite very different parts of the web. AI Overviews lean on video, social and community platforms, while ChatGPT leans on reference sites and publishers. Citation volume is also concentrated in a few industries and a few large domains within them.
- Arts & Entertainment leads AI Overview citations with 135.7 million, more than three times News & Media’s 39.5 million. Health has the most domains among the top 1,000 cited (122).
- Arts & Entertainment also leads ChatGPT, with 13.7 million citing answers and 157 of the top 1,000 cited domains. Findings 10 and 11 are covered in the industry breakdown.
- The two platforms favor different sources. YouTube leads AI Overviews with 51.9 million citations but ranks 19th in ChatGPT. Wikipedia leads ChatGPT with 4.88 million. 27.3% of ChatGPT answers have no source citation, versus 0.7% of AI Overviews. See YouTube leads AI Overviews, Wikipedia leads ChatGPT.
UGC and backlinks
Link signals still go along with visibility in both classic and AI search, but the report is careful to call these associations, not causes. Reddit, meanwhile, has become a fixture of Google’s organic results, not just of AI answers.
- Reddit is in about a third of Google top-10 results. It appeared in 32.15% of tracked results in Q3 2026, against 4.11% for Quora, and its share moved less than three points in four quarters. See Reddit is in 32% of Google’s top 10.
- More UGC backlinks go with more AI citations. UGC links correlate with citations at Spearman 0.342 for AI Overviews and 0.314 for ChatGPT, but overall referring domains correlate more strongly. See do UGC backlinks help AI citations?
- Backlink strength still matters. Domains ranking first have a median of 111 referring domains, 31% more than positions 4–10. Domains cited in AI Overviews for the hardest keywords have 5.6 times more referring domains than those cited for the easiest. See do backlinks still matter in 2026?
What AI engines get wrong
AI engines are a poor source for these numbers right now. On November 7, 2026, we ran 11 of the report’s questions as one-time prompts in AmICited across ChatGPT, Perplexity, Gemini, Grok, DeepSeek and Google AI Mode. They often contradicted each other, mixed incompatible studies and repeated 2025 figures as current.
| Question | What the engines answered | What Search Insider 2026 found |
|---|---|---|
| Share of Google searches with AI Overviews | From about 43–44% (ChatGPT, Perplexity) to 80–85% (Grok) | 61.43% of tracked results, August 2026 |
| Position 1 organic CTR | From 7.1% to 39.8%, depending on the engine and study it picked | Desktop 7.43%, mobile 20.80% (August 2026) |
| Real Estate AI Overview rate | One ChatGPT answer quoted both 22.27% and 78.5% from two studies | 22.27% |
| Do AI Overviews trigger on transactional searches? | Perplexity said transactional presence is declining | Rose from 10.82% to 28.64% in three quarters |
| Correlation of links with AI citations | Google AI Mode claimed “near-zero”, citing a Reddit thread | Spearman 0.406 (AI Overviews) for referring domains |
Most of the disagreement comes from study design rather than error. A study of real user searches, a 20-million-keyword panel and a 400-keyword commercial panel will report different AI Overview rates, and all can be accurate. The problem is that AI answers rarely say which kind of number they’re quoting.
Clicks are a good example. Pew Research Center found that users clicked a link inside Google’s AI summary in just 1% of visits in March 2025. That sounds like it contradicts DataForSEO’s 42–45%, but the two measure different things. Pew counts all visits, including the many that end without a click. DataForSEO estimates where the clicks go among searches that get one. Each article in this series explains the differences for its topic.
The five priorities, mapped
DataForSEO closes the report with five priorities for SEO and GEO. Each one depends on measuring something that classic rank tracking doesn’t show. Here’s what each priority asks you to track, and where AmICited can help.
| DataForSEO priority | What to measure | Where AmICited helps |
|---|---|---|
| Look beyond your own website | Which third-party pages rank or get cited for your topics, and whether your brand appears in them | Source & Citation Intelligence |
| Pay attention to Reddit and relevant communities | Which threads rank and get cited for your keywords, and what they say about you | UGC Influence |
| Build strong link profiles, don’t chase UGC links for numbers | Referring-domain growth next to citation growth | Rankings vs citations |
| Evaluate SEO and GEO competition separately | Who wins Google rankings versus who wins each AI engine’s citations | Competitor Analysis |
| Measure visibility across multiple surfaces | Rankings, CTR, AI citations and mentions side by side | AI Visibility, CTR gap |
What brands should do now
- Check AI Overview presence for your own keywords. The 61% average hides big differences by industry and intent. Run your priority queries through a tracker and see where AI Overviews appear. Our guide to tracking Google AI Overviews covers the setup.
- Re-baseline your CTR expectations by device. Compare your Search Console CTR by position with the desktop and mobile figures in the CTR breakdown before you blame a ranking drop.
- Track citations, not just rankings. If AI Overview citations take 42–45% of clicks when they appear, being cited is a click source on par with a top ranking, though that share is split among every cited link. Prompt tracking shows which engines cite you and which competitors they cite instead.
- Map the third-party sources in your category. Find the YouTube videos, Reddit threads and reference pages that rank or get cited for your topics, and check whether your brand appears in them.
- Keep building links the normal way. Referring domains go along with both rankings and citations. A diverse, relevant link profile is a safer bet than chasing one kind of link.
The takeaway
Search Insider 2026 doesn’t say SEO is dead. It says ranking your own site is no longer the only way to be found. People now meet brands in AI answers, YouTube videos, Reddit threads and publisher pages, often without visiting the brand’s website. To see the whole picture, you have to measure all of those places, engine by engine. The articles in this series give you the numbers to start from.
