Generative Engine Optimization Statistics: 2026 Search Demand Data

Here are generative engine optimization statistics you can check yourself. In Google Ads data we pulled on 2026-10-16, "generative engine optimization" averaged 4,400 US searches a month over the past year (880 in the UK), 35% more than the year before. But the term peaked in August and September 2025, and in September 2026 "answer engine optimization" matched it for the first time since people began searching for "generative engine optimization" in December 2023.

Most GEO statistics pages recycle vendor surveys. This one is built on first-party data: Google Ads search-volume estimates for 234 GEO, AEO and AI-search terms in the US and UK, with four years of US monthly history. Below you get the GEO search trends, the method, the traps we removed, and a check of which widely quoted GEO statistics survive a look at their primary source.

Generative engine optimization statistics at a glance

• 0 to 4,400. US searches for "generative engine optimization" were zero every month until December 2023, a month after the paper that coined the term appeared on arXiv. They averaged 4,400 a month from October 2025 to September 2026, below the 6,600 peak of August and September 2025.
• 4,400. US searches for "answer engine optimization" in September 2026, its highest month on record. Its 12-month average is up 92%.
• 8,100 and 3,600. US searches in September 2026 for "what is aeo" and "what is generative engine optimization". Both are records. The market is still learning the words.
• Down 13%. "AI SEO" is still the biggest name for the practice (6,600 a month) but the only big one shrinking. It is now 1.7 times "generative engine optimization", not the 4 times our April 2026 version of this post reported from Google Trends.
• 135,000. Average monthly US searches for "ai overviews", up 284%. "google ai mode" reached 1.5 million in September 2026. People search for the AI surfaces far more than for ways to optimize for them.
• About 25 to 1. "llms.txt" (5,400 a month) against "oai-searchbot" (210), the crawler OpenAI actually documents as the control for appearing in ChatGPT search.
• 10 to 20. Monthly US searches for "generative engine optimization statistics" since February 2026, after a short-lived peak of 720 in October 2025. Demand for GEO statistics is small. Demand for accurate ones should be larger.

Where these numbers come from

Every volume here comes from the DataForSEO Google Ads search-volume endpoint, queried on 2026-10-16 for 234 English-language terms, once for the United States and once for the United Kingdom. The latest complete month is September 2026. US results include monthly history back to November 2022; UK results cover the last 12 months. The whole pull cost $0.18, so anyone with an account can reproduce it.

The "average per month" columns are Google's own 12-month figure (October 2025 to September 2026). The year-on-year changes are ours: we averaged the 12 monthly values for October 2025 to September 2026 and compared them with October 2024 to September 2025. Comparing 12-month averages removes most seasonal noise and one-month spikes.

What a Google Ads volume is, and is not

• It is an estimate of Google searches in one country. It says nothing about what people type into ChatGPT, Perplexity or Claude. No AI platform publishes prompt volumes.
• Google Ads "provides combined search volume values for groups of similar keywords", according to the same DataForSEO documentation. That is why "aeo tool" and "aeo tools" both return 390. Never add close variants together.
• Every value in our pull sits on a fixed ladder (720, 880, 1,000, 1,300, 1,600 and so on). A move from 1,300 to 1,600 can be a smaller real change than it looks. Read percentages on small terms as direction, not precision.

Namesakes we removed

• "aeo" gets 27,100 US searches a month, but it already averaged about 14,000 a month from November 2022 to September 2024, before answer engine optimization was a search topic. Most of it is something else; AEO is, for one, American Eagle Outfitters' stock ticker. We use "answer engine optimization" and "what is aeo" instead.
• "geo statistics" (320 a month) means geostatistics, a branch of spatial statistics. Every result on Google's first page is about it, and it was searched just as often in 2023.
• "claudebot" jumped from 170 searches a month in late 2025 to 33,100 in February 2026, then fell back. That lines up with the viral open-source agent called Clawdbot, not a sudden interest in Anthropic's crawler. We left it out.

GEO, AEO, AI SEO or LLMO: what people call it

Term	US avg / month	UK avg / month	US, Sep 2026	12-month change (US)	US peak
ai seo	6,600	1,600	5,400	−13%	12,100 (Oct 2024, Sep 2025)
generative engine optimization	4,400	880	4,400	+35%	6,600 (Aug–Sep 2025)
geo seo	2,400	1,000	2,400	+153%	3,600 (Mar 2026)
answer engine optimization	2,400	320	4,400	+92%	4,400 (Sep 2026)
ai search optimization	1,300	110	1,600	+140%	1,900 (Mar 2026)
ai visibility	880	210	1,300	+439%	1,300 (Mar, Jul, Sep 2026)
llm seo	720	170	590	+24%	1,300 (Jun, Oct 2025)
llmo	390	110	320	−22%	1,600 (Jun 2025)
chatgpt seo	320	90	390	−24%	1,300 (Feb 2023)
search everywhere optimization	210	30	110	−22%	590 (Sep 2025)

Three things stand out. First, "AI SEO" is losing ground. In April we told readers to lead with it because Google Trends showed four times the interest of "generative engine optimization". On real volumes the gap is now 1.7 to 1 over 12 months and 1.2 to 1 in September 2026 (5,400 against 4,400). That advice is out of date.

Second, "answer engine optimization" is the only established name to set a record in September 2026, and it is mostly American. In the UK, "geo seo" (1,000 a month) is searched three times as often as "answer engine optimization" (320). If your buyers are British, the GEO framing reaches more of them.

Third, the 2025 coinages did not stick. "LLMO" and "search everywhere optimization" both sit well below their 2025 peaks. "AI visibility" is the exception: its search volume is small, but it is searched more than five times as often as in the year before.

The market is still asking "what is it?"

Question	US avg / month	UK avg / month	US, Sep 2026	12-month change (US)
what is geo	5,400	1,600	6,600	+141%
what is aeo	5,400	880	8,100	+389%
what is generative engine optimization	1,300	50	3,600	+309%
what is answer engine optimization	1,000	40	2,900	+531%
geo vs seo	2,900	590	2,400	+105%
seo vs geo	1,900	390	1,900	+147%
geo vs seo vs aeo	320	70	320	from 38 to 291 a month
is geo replacing seo	50	10	170	from 3 to 58 a month

Definition searches set records in September 2026, almost three years after the term was coined. One caveat: "what is geo" already drew about 600 searches a month from November 2022 to September 2024 from other meanings of "geo", so part of its volume is not about marketing.

The comparison searches ("geo vs seo") have levelled off since their 2025 peak, while the "what is" searches keep climbing. Read together, newcomers are still arriving faster than the early audience is moving on. If you publish on this topic, a plain definition (what is GEO) and an honest comparison (SEO vs GEO) still answer what most people are asking.

AI search statistics: the surfaces outgrow the tactics

Term	US avg / month	UK avg / month	US, Sep 2026	12-month change (US)
google ai mode	368,000	40,500	1,500,000	+855%
ai overviews	135,000	18,100	246,000	+284%
seo	90,500	18,100	60,500	−35%
ai search	22,200	5,400	27,100	+57%
google ai overviews	18,100	1,300	14,800	+33%

Most of these searches are people trying to reach or understand Google's AI features, not marketers. The Google Ads estimate for "seo" fell 35% on 12-month averages. Volume data cannot tell you why, and estimates for one-word head terms are coarse, so treat that as a signal to watch rather than a verdict on SEO.

The ratio is clearer. From October 2023 to September 2024, "seo" was searched about 260 times as often as "generative engine optimization" (leaving out a one-month spike to 1,000,000 in June 2024). Over the past 12 months it was about 22 times. GEO is still a niche, but a much smaller one relative to SEO than two years ago.

Usage figures the platforms publish themselves

• ChatGPT: "more than 900M weekly active users", OpenAI, 2026-02-27.
• Gemini app: 950 million monthly active users, and AI Mode: "surpassed 1 billion monthly active users", both from Alphabet's Q2 2026 earnings remarks, 2026-07-22. The same remarks say Google is "sending billions of clicks to websites every week through AI features in Search", with no per-site breakdown.
• Clicks when an AI summary appears: users clicked a traditional result in 8% of visits with an AI summary against 15% without one, and clicked a link inside the summary in 1% of visits. That is Pew Research Center browsing data from 900 US adults in March 2025.

Weekly and monthly users are different measures, so never add these together or compare them directly.

Tool and agency searches: buyers are shopping

Term	US avg / month	UK avg / month	US, Sep 2026	12-month change (US)
ai seo tools	1,900	210	1,600	−22%
ai visibility tool	880	170	1,300	+5%
geo tools	720	110	1,300	+67%
best ai visibility tools	590	40	1,300	from 77 to 520 a month
aeo agency	590	140	590	+102%
generative engine optimization agency	390	30	260	from 89 to 432 a month
aeo tools	390	70	590	−20%
ai visibility tracking	320	70	390	+35%
ai rank tracker	260	30	260	+22%

Generic "ai seo tools" is shrinking while "geo tools" and "best ai visibility tools" grow. Several terms spiked in September 2025 ("ai visibility tool" hit 9,900, "aeo tools" 5,400) and fell straight back, so ignore single months.

One term deserves a warning. People search for an "ai rank tracker", but there is no verified rank inside an AI answer to track. Google says plainly that "No third-party tool has access to our internal ranking or AI systems". What a tool can honestly report is whether you were mentioned, cited and described correctly. Vendor brand searches, funding and prices are in our comparison of GEO platforms.

People search for llms.txt 25 times more than for the crawler that matters

Term	US avg / month	UK avg / month	US, Sep 2026	12-month change (US)
llms.txt	5,400	1,300	4,400	+27% (peak 8,100, Jun–Aug 2025)
ai crawlers	390	90	590	+16%
gptbot	260	90	260	−22%
oai-searchbot	210	50	480	+29% (record month)
cloudflare ai crawl control	210	20	210	from 7 to 228 a month
google-extended	140	50	140	+4%
perplexitybot	70	30	140	from 81 to 70 a month

This is the most lopsided pair in the dataset. Google says of AI text files that creating them "will neither harm nor help your site's visibility or rankings in Google Search, as Google Search ignores them", and no other AI engine documents reading llms.txt.

OAI-SearchBot is the opposite: a documented, binary control. OpenAI states that "Sites that are opted out of OAI-SearchBot will not be shown in ChatGPT search answers". Its help center adds a second condition: "allow OAI-Searchbot to crawl the site and confirm that the website host or content delivery network allows traffic from OpenAI's published searchbot IP addresses". Searches for it hit a record 480 in September 2026, and are still a fraction of the llms.txt interest.

1. Open yoursite.com/robots.txt. Look for a Disallow: / under User-agent: OAI-SearchBot, PerplexityBot, Claude-SearchBot, or under User-agent: *, which applies to every bot without its own group.
2. If you want to appear in AI search but stay out of OpenAI model training, the groups look like this. OpenAI says "Each setting is independent of the others", so blocking GPTBot does not remove you from ChatGPT search.

   User-agent: OAI-SearchBot
   Allow: /
   
   User-agent: PerplexityBot
   Allow: /
   
   User-agent: Claude-SearchBot
   Allow: /
   
   User-agent: GPTBot
   Disallow: /

3. Check your CDN or firewall. A firewall block overrides a robots.txt "allow". In Cloudflare, review the AI crawler settings for your zone, especially after Cloudflare's AI crawler default change.
4. Do not treat robots.txt as an off switch either. Perplexity says its user-triggered fetcher "generally ignores robots.txt rules", and OpenAI says robots.txt rules "may not apply" to ChatGPT-User.

GEO statistics that hold up, and ones to stop quoting

Statistic	Source and date	What it actually measures	Quote it?
37.9% of URLs cited in AI Overviews also appear in Google's top 10	Ahrefs, 2026-03-02; 863K SERPs, 4M cited URLs	Overlap between AI Overview citations and the first 10 results	Yes, dated. Do not pair it with Ahrefs' older 76% to claim a trend: Ahrefs says it improved its parsing method between the two studies.
Adding schema "produced no major uplift in citations on any platform"; AI Overviews −4.6%	Ahrefs, 2026-05-11; 1,885 pages against matched controls	Pages that already had 100+ AI Overview citations	Yes, with the limit: it does not test pages AI is not citing yet. More in schema markup for AI visibility.
8% vs 15% clicks with and without an AI summary	Pew Research Center, 2025-07-22 (linked above)	Browsing of 900 US adults in March 2025	Yes, as a March 2025 snapshot
No reviewed technique shows a stable, cross-platform effect on discoverability	Critical survey of 45 GEO studies, 2026-07-15	A literature review; single author, not peer reviewed	Yes, as the best summary available
"GEO can boost visibility by up to 40%"	Aggarwal et al., arXiv 2311.09735 (KDD 2024), linked above	A test engine the authors built, with the sources already placed in its context	No, not as an uplift on live AI platforms
"ChatGPT is 92% of AI traffic"	Agency referral panels	Clicks that analytics tools could label as AI referrals, not AI usage	No
"AI visitors convert 4.4x (or 23x) better"	Ahrefs, 2025-06-16 (23x); Semrush (4.4x)	One company's own site signups (Ahrefs); a conversion comparison with no disclosed sample or method (Semrush)	No. Both studies exist, but neither is controlled or multi-site, so do not generalize them.

Market-size figures for "the GEO market" also circulate. The ones we found disagree with each other and come from paid research reports we could not inspect, so we do not quote any.

How to pull and check your own GEO keyword data

1. Get volumes. Use Google Ads Keyword Planner (free with a Google Ads account) or a keyword API such as DataForSEO. Set the country and language before you read anything.
2. Check the term before the topic existed. Pull 2022 and 2023. If a term was already searched then, you are partly measuring a namesake, as with "aeo" and "geo statistics".
3. Google the term. If page one is about something else, the volume is not yours.
4. Compare 12-month averages year on year. Single months spike and fall back; September 2025 had several of those.
5. Never add close variants. Google groups similar keywords, so adding them double counts.
6. Before quoting any GEO statistic, open the primary source. Check the date, the sample, and what was measured: a live AI platform, or a lab setup with documents already in context.
7. Date every number. Re-pull quarterly. Ours is dated 2026-10-16.

Frequently asked questions

How many people search for generative engine optimization?

About 4,400 a month in the US and 880 in the UK, on Google's 12-month average to September 2026. That is up 35% on the year before, but below the August 2025 peak of 6,600. The figures are Google Ads estimates pulled on 2026-10-16.

Is search interest in GEO still growing?

Interest in the topic is, but not in every name for it. "Answer engine optimization" and the "what is…" questions hit records in September 2026, while "generative engine optimization" and "AI SEO" are below their peaks. The broad picture is a growing audience still learning the vocabulary.

Is GEO replacing SEO?

No. "seo" is still searched about 22 times as often as "generative engine optimization". Google also says there are "no additional requirements to appear in AI Overviews or AI Mode, nor other special optimizations necessary" beyond being indexed and eligible for a snippet.

Should I use GEO or AEO on my site?

Use both, naturally, and pick the lead term by market. In the US, "answer engine optimization" now matches "generative engine optimization" month to month. In the UK, GEO terms are searched about three times as often. Our answer engine optimization guide covers how the two overlap.

Can I trust GEO statistics I find online?

Only the ones you can trace to a primary source with a date and a sample. Many repeated figures, such as the "40% visibility" uplift and conversion multipliers, describe lab setups, a single company's own site, or an undisclosed method. Use the table above as a starting list of what holds up.
