Search bar and AI conversation bubble: SEO is not dead, search behavior is changing.

People are not abandoning Google for ChatGPT. They are adding AI to the way they research, compare, and make decisions. New data shows 95% of ChatGPT users still use Google, even as generative AI usage grows quickly. SEO is not disappearing. It is being asked to do a bigger job.

Answer: SEO is nowhere near dead. Google still reaches nearly all ChatGPT users, but AI tools are changing which searches people make and how often they click. Businesses now need to be visible in traditional results, AI-generated answers, and the sources those systems use.

The panic headline is easy: “AI is killing Google.”

The data tells a more interesting story.

The strongest evidence that Google is not being replaced

Similarweb published a useful number in August 2026.

In September 2025, 95% of ChatGPT users also used Google. Eight months later, in May 2026, the overlap was still 95%.

That happened while worldwide visits to generative AI platforms reached 9.5 billion per month, up 70% year over year, according to Similarweb.

If people were leaving Google in large numbers and replacing it with ChatGPT, we would expect the overlap to fall. It did not.

People are using both.

That lines up with an earlier Semrush study based on 260 billion rows of clickstream data collected between January 2024 and June 2025. Semrush examined Google activity before and after people first used ChatGPT. It found that Google usage stayed steady and even increased slightly after ChatGPT adoption.

These findings argue against wholesale abandonment of Google. They do not rule out individual queries moving to AI.

A buyer might ask ChatGPT to explain a category, use Google to check a company, open Reddit to look for unfiltered opinions, visit YouTube for a demonstration, and then return to Google Maps for directions or reviews.

That is one buying journey. Not five separate ones.

Why search traffic can still fall

Here is the part people miss.

Google can remain heavily used while websites receive fewer visits from it.

Audience, query volume, and clicks are different measurements.

As reported by Search Engine Journal, a Bocconi University working paper examined U.S. desktop clickstream data from October 2024 through July 2025. Households that gained access to ChatGPT Search reduced their traditional search queries by an average of 3.14 per week, about 9.4% below the earlier average of 33.51.

After 20 weeks, the gap reached 17%.

The study also found that the largest declines in search referrals were concentrated in informational categories. Academic sites fell 32.8%, reference sites fell 26.5%, developer sites fell 15.1%, and news sites fell 13.4%.

The authors were careful. These patterns were descriptive and did not prove causation.

Still, the direction makes sense.

People can continue using Google while moving some research questions to ChatGPT. They can also stay inside Google and get an answer from AI Overviews or AI Mode without visiting another website.

So yes, Google can keep its audience.

And yes, some publishers can lose clicks.

Both things can be true.

That does not mean SEO is dead. It means traffic alone no longer tells the whole story.

A lot of the “SEO is dead” talk comes from a narrow definition of SEO.

If SEO means publishing thin articles, stuffing in keywords, and chasing rankings with no thought for the buyer, then that version should die. It was not very good to begin with.

Real SEO has always been about helping the right person find the right business, answer, product, or service.

The interface is changing. The job is not.

Google still matters. Search results still matter. Websites still matter. In fact, websites may matter more because AI systems need public source material to understand a business and decide whether it belongs in an answer.

ChatGPT does not magically know that your company is credible.

Neither does Google.

They look for evidence.

Your service pages, expert content, case studies, reviews, outside mentions, product information, and consistent business details all help form that evidence.

A vague website gives search engines and AI systems very little to work with. A clear one makes the business easier to understand, verify, compare, and recommend.

That builds on SEO fundamentals, with additional work for AI Findability.

It is simply operating across more surfaces.

What AI changes about the job

Traditional search often gave users a list of options.

AI search is more likely to give them a summarized answer, a shortlist, or a recommendation.

That is a meaningful shift.

Ranking fifth on a results page and being excluded from a three-company AI shortlist are not the same outcome.

Businesses now have to think about three layers of visibility:

  1. Can people find the business in traditional search?
  2. Can AI systems understand what the business does and when it is relevant?
  3. Is there enough credible evidence for the business to be mentioned or recommended?

This is why I do not buy the idea that AI makes SEO irrelevant.

AI increases the need for clear positioning, useful content, technical accessibility, authority, and proof. Those are not side issues. They are the raw material behind discovery.

The big change is that a click is no longer guaranteed.

A person may learn about your company from an AI answer, search the brand on Google later, and contact you without ever following the original citation. Standard analytics may not connect those steps.

That makes measurement harder. It does not make visibility worthless.

What businesses should do now

Do not choose between Google and AI search.

That is the wrong decision.

The audience data shows people using both. It does not establish what happens inside a single buying journey. Your strategy should make room for either route.

Start with one question:

Can Google, ChatGPT, and a real buyer quickly understand who you help, what you do, and why they should trust you?

If the answer is not obvious, fix that before chasing another platform or acronym.

Make the important pages clear. Publish material that answers real buying questions. Show proof where people can find it. Keep company details accurate across the web. Track branded searches, qualified leads, AI mentions, and assisted conversions alongside rankings and organic traffic.

Do not throw away the SEO work that still produces results.

Build on it.

The companies in the strongest position will not be the ones betting everything on Google or rushing to rename every service “GEO.” They will be the ones that understand the real shift.

Search is expanding.

Discovery is becoming less linear.

Answers are appearing before clicks.

And the website is still one of the main sources machines and people use to decide whether a business deserves attention.

SEO is not dead.

It just has more places to show up.
