State of AI Search — July 2026

rocketblue’s monthly read on how AI engines actually cite, mention, and rank brands. Aggregate data across every brand and organization monitored on the rocketblue platform — not one company’s numbers, but the market’s.

The 60-second version

• ChatGPT includes a citation in 94.7% of responses; Google AI Overview in 79.3% — the two engines carrying the most real-world traffic, and they don’t behave alike even at the top.
• When ChatGPT cites, it cites more: 11.75 sources per cited response on average, roughly 48% more than AI Overview’s 7.92.
• No single domain dominates AI citations: the top 25 most-cited domains combined account for just 10.6% of everything cited this month.
• Homepages and blog posts are the two most-cited content types, together making up roughly 40% of all citations.
• 71.4% of brand mentions in AI answers were positive. The bigger risk is invisibility — 24.5% of responses named no brand at all.
• Only 18.96% of citations show up inline in the visible answer. Most are footnotes nobody reads.

AI Overview vs. ChatGPT: the two that matter most

Google AI Overview and ChatGPT carry the most real-world search traffic of any AI surfaces we track, so they’re where we’re putting most of our analysis each month.

ChatGPT includes at least one citation in 94.7% of its responses. AI Overview does it in 79.3%. Both cite most of the time — ChatGPT is closer to “always.”

The gap widens once a citation happens at all: cited ChatGPT responses carry an average of 11.75 sources, cited AI Overview responses carry 7.92 — about 48% more sources per answer from ChatGPT. ChatGPT also draws from a noticeably wider pool of sources, touching roughly 1.6x as many unique domains as AI Overview this month (84,359 vs. 53,253).

Takeaway: don’t assume one GEO playbook covers both. AI Overview rewards being part of a smaller, more concentrated set of trusted sources; ChatGPT rewards being findable across a much wider field.

The citation landscape

Across all engines this month, out of more than 1.8M citations analyzed, no domain comes close to dominating. youtube.com led at 2.16% of all citations, followed by reddit.com (1.73%) and google.com (1.26%). linkedin.com and tripadvisor.com tied at 0.36% each, ahead of clutch.co, techradar.com, and gov.uk (all under 0.4%).

The top 25 most-cited domains combined account for just 10.6% of total citations. AI citation is a long tail, not a monopoly — there’s more room in this landscape than the usual “a few giants own it” narrative suggests.

How the engines actually differ

*Claude often returns answers with no citations by design, and our tracked sample for Claude this month was small and uneven across brands. We’re treating Claude’s numbers as directional only and not drawing behavioral conclusions from them yet.

ChatGPT and AI Overview lead on traffic, which is why they anchor this report. Gemini and AI Mode land close to AI Overview’s citation behavior. Perplexity cites less often, but more heavily when it does — its 10.90 average citations per cited response is the second-highest of any engine, behind only ChatGPT.

Brands: named, not necessarily won

• 24.5% of all analyzed responses named zero brands.
• 46.9% named 4-9 brands; 14.7% named 10 or more.
• Perplexity was the exception — median 2 brands per response, the least crowded field of any engine.
• Sentiment when brands were named ran heavily positive: 71.4% positive, 28.3% neutral, 0.3% negative, across 1.3M+ brand mentions analyzed.

The practical read: the risk in AI search isn’t reputational. It’s invisibility. Almost nobody gets mentioned and then trashed. They just don’t get mentioned.

What actually gets cited

We analyzed the properties of the source pages AI engines cited. A few things stand out:

• Homepages: 20.1% of citations — the single most-cited content type.
• Blog posts: 19.75% — combined with homepages, that’s more than product pages, guides, listicles, and comparison pages put together.
  
• Median cited page length: 1,428 characters — well under what most SEO playbooks recommend for “comprehensive” content.
• 83.2% of cited pages used bullet points.
• 66.6% included visual data.
• Only 8.2% presented original research.

One more distinction worth knowing: only 18.96% of all citations appeared inline in the visible answer text. The rest were reference-only — footnotes a user would have to click to ever see. Being cited and being seen are not the same metric.

(The median page length and structural figures — bullet points, visual data, original research — are based on a deep-dive sample of 368 analyzed source pages, not the full citation set: directional, not exhaustive. The homepage/blog citation-share figures are from the full dataset of 1.8M+ citations.)

What this means for your strategy this month

ChatGPT and AI Overview are the two engines worth building your GEO strategy around first — they carry the traffic. But they don’t behave identically even at the top, so don’t assume one playbook covers both. And across every engine, citations concentrate less than you’d think: the top 25 domains combined are just 10.6% of all citations. There’s real room in this landscape for brands that aren’t already giants.

We’ll be back with the August numbers in early September.

Frequently asked questions

Which AI engine cites sources most often? ChatGPT, including at least one citation in 94.7% of its responses — the highest rate among the engines we track with full confidence this month. (We’re not yet reporting on Claude’s citation behavior with the same confidence — see the note in the engine comparison above.)

What’s the most-cited domain across AI engines right now? YouTube, at 2.16% of all citations analyzed in July, followed by Reddit (1.73%) and Google.com (1.26%). No domain comes close to dominating — the top 25 most-cited domains combined make up just 10.6% of total citations.

How long should content be to get cited by AI? Based on rocketblue’s analysis of cited source pages, the median length is 1,428 characters — short and structured, not exhaustive. Length matters less than clear structure: bullet points, visual data, and a stated point of view correlate more strongly with citation than word count.

Does getting mentioned by AI risk negative brand sentiment? Rarely. Across all brand mentions analyzed in July, 71.4% were positive and only 0.3% were negative. The bigger risk is not being mentioned at all — 24.5% of analyzed responses named no brand.

Methodology: rocketblue sends a weekly set of prompts — system-generated and user-defined — to ChatGPT, Google Gemini, Google AI Overview, Google AI Mode, Perplexity, and Claude, replicating how a real user would ask a question in a given target country. Responses are analyzed for brand mentions, sentiment, and cited sources. Copilot and Grok are excluded — too little query volume on the platform to be statistically reliable. Claude’s citation figures this month reflect a small, uneven sample of tracked brands and are reported directionally rather than analyzed in depth. Response-volume figures reflect rocketblue‘s own prompt-scheduling mix across customer brands, not the engines’ real-world usage share, and should not be read as market share. “Citations” refers to sources an AI response referenced, not clicks or traffic. All figures are final month-end numbers for July 1–August 1, 2026.
