A quiet but significant change has been happening on the internet for the last year.
In the past, when people researched something, they would go to Google, open a few sites, look at forums, read comments, and finally make a decision. Now, a significant portion of users, especially those close to technology, have started asking questions directly to artificial intelligence.
“Which is the best hosting?”
“Which accounting software makes more sense?”
“Is there a reliable spare parts website for Ford Focus?”
“How to calculate a home loan?”
And most of the time, the answer is no longer the classic results from Google;
ChatGPT, Gemini, Perplexity, or Copilot provide it.
This change has actually initiated a new era in the SEO world.
Because the issue is no longer just about ranking on Google.
The real issue has become:
Do artificial intelligence systems see your website as a reliable source?
This is the foundation of the recently frequently heard concepts of “ChatGPT SEO”, “AI SEO”, and “GEO”.
What is ChatGPT SEO?
In short, ChatGPT SEO is the general term for optimizations made for a website to be:
more easily understood by AI systems,
found reliable,
and usable as a source in their answers.
It's not an entirely different world from classic SEO, but some important differences have started to emerge.
For example, a few years ago:
long-form content,
plenty of keywords,
aggressive SEO techniques
were much more effective.
Today, however, the situation is changing somewhat, especially regarding AI systems. Because artificial intelligence no longer solely looks at “keyword density.” It tries to understand whether the content is truly useful.
Therefore, it's observed recently that:
over-inflated,
too sterile,
and formulaically written content
does not perform as strongly as before.
Especially if the user experience is weak.
Why is Everyone Talking About GEO Recently?
GEO stands for:
Generative Engine Optimization
Which is roughly:
“Optimization for artificial intelligence engines.”
A few years ago, it honestly sounded a bit like an unnecessary buzzword. But now it has started to gain serious importance.
Because user behavior is truly changing.
For example, many users now:
instead of searching for “best air conditioner brand”
on Google, ask ChatGPT directly.
A similar situation:
finance,
software,
automotive,
health,
education
has also started to emerge in fields such as these.
Therefore, in the coming period, not only Google rankings but also
being visible in AI systems could become a significant source of traffic.
Especially for sites that act early.
How Do Artificial Intelligence Systems Evaluate a Website?
The most important part of the job actually starts here.
Because many people still continue to produce content with the old SEO mindset:
unnecessarily long articles,
unreadable introductory paragraphs,
constant keyword repetition,
inflated titles like “2026 ultimate guide.”
However, modern AI systems can distinguish most of these.
Especially since an incredible amount of AI content has emerged on the internet recently,
artificial intelligence is now paying more attention to some different signals.
For example:
does the content truly teach something,
is there a sense of expertise,
is the user experience natural,
does the brand inspire trust,
is the content quotable.
These are becoming increasingly important.
The Real Differentiator: Trust
I think this is the point many people miss.
Artificial intelligence actually tries to find “reliable sources” on the internet.
Therefore:
a genuine brand feel,
user reviews,
natural mentions across the internet,
technical consistency,
clear contact information
are becoming important.
For instance, a significant difference has begun to emerge between sites launched solely for SEO purposes, which convey no brand feeling,
and sites with a real user base.
Especially:
Reddit,
forums,
user reviews,
social media conversations
can be more important for AI systems than we think.
Because these carry real user signals.
The Reason for Reddit's Growth Isn't Coincidence
Recently, when searching for something on Google, we started seeing Reddit constantly.
The fundamental reason for this is actually very simple:
real user experience.
Similarly, AI systems can:
see people's natural conversations
as more valuable than pre-written SEO texts.
Especially for queries like:
“best”
“which to buy”
“is it reliable”
“does anyone use it”
user experience has become very important.
Therefore, simply producing content is no longer enough. It's also important for people to talk about your brand naturally.
Technical SEO is Still Important
Sometimes, when GEO is discussed, people think classic SEO is over.
Actually, it's the opposite.
Because artificial intelligence systems still crawl websites via the internet. So, if there are technical problems, these systems also cannot read your site properly.
Especially the following issues are still critical:
sitemap.xml
robots.txt
proper heading structure
fast loading pages
mobile compatibility
clean HTML structure
On some sites, even the content structure cannot be read properly due to excessive JavaScript usage.
These types of technical problems can affect not only Google but also
AI systems.
Is LLMs.txt Really Important?
This has been one of the most talked-about topics in recent months.
The LLMs.txt file essentially aims to tell AI systems:
“These are the important contents on this site.”
Logically, it's somewhat similar to robots.txt.
Especially:
large blogs,
SaaS platforms,
documentation sites
it can be useful for.
But sometimes it's overemphasized on the internet.
Because adding llms.txt alone
does not make a bad site visible.
What's truly important is still:
quality content,
trust,
user experience,
brand authority.
In other words, if the foundation is weak,
technical files alone do not create miracles.
Why Do AI Systems Cite Some Websites More Often?
There are some common points that stand out here.
Generally, content that AI systems refer to more often:
is written clearly,
provides direct information,
doesn't unnecessarily elaborate,
contains definitional sentences,
gives quick answers to user questions.
For example, sentences like these are:
quite useful for AI systems.
“GEO is the optimization process aimed at increasing visibility in artificial intelligence systems.”
Because:
it's short,
clear,
and the context is explicit.
Content in a question-and-answer format, in particular, seems to be performing more strongly recently.
Content Writing is Changing Slightly in the AI Era
In the past, there was a lot of content that ranked simply for being long.
Now, user behavior is diversifying.
People now:
want quick answers,
seek clear information,
are tired of unnecessary introductions.
AI systems have also noticed this.
Therefore, in the new era:
content with high information density,
readable,
and conveying a sense of real experience
could be much more important.
Especially:
content that appears too perfect,
written in a robotic rhythm
is now more easily noticed.
The ironic part is this:
“content that looks like it was written for AI”
can sometimes even generate a weak signal for AI systems.
How Is AI Visibility Measured?
Classic SEO tools measure metrics such as:
ranking,
backlinks,
organic traffic.
However, artificial intelligence visibility is a somewhat different area.
Because here the issue is:
citability,
AI accessibility,
content structure,
trust signals,
technical readability.
That's why AI visibility tools have started to emerge recently.
For example:
GeoSkoru
and similar platforms help analyze how strongly websites appear from the perspective of artificial intelligence systems.
Since this field is still very new,
sites that act early are highly likely to gain a significant advantage in the next few years.
Conclusion
SEO is not ending.
But the way the internet works is changing.
In the coming period, the most powerful websites will likely be:
not only those optimized for Google,
but also those deemed reliable by artificial intelligence systems.
Therefore, the question is no longer just:
“What's my ranking on Google?”
anymore.
The real question is:
Do artificial intelligence systems truly find your site worthy of being cited as a source?
