A silent but significant change has been happening on the internet in the last year.
In the past, when people researched something, they would go to Google, open a few sites, check 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 AI.
“Which is the best hosting?”
“Which accounting software is more sensible?”
“Is there a reliable spare parts website for Ford Focus?”
“How to calculate home loan?”
And most of the time, the answer no longer comes from classic Google results;
ChatGPT, Gemini, Perplexity, or Copilot provide it.
This change has actually ushered in a new era in the SEO world.
Because now, the issue is not just about ranking on Google.
The real issue has become:
Do artificial intelligences see your site as a reliable source?
This is precisely what lies at the core of the recently common terms "ChatGPT SEO", "AI SEO", and "GEO".
What is ChatGPT SEO?
Briefly, ChatGPT SEO is the general name for optimizations made for a site to be:
more easily understood,
found reliable,
usable as a source in answers
by artificial intelligence systems.
Actually, it's not a completely different world from classic SEO. But some important differences have started to emerge.
For example, a few years ago:
long content,
plenty of keywords,
aggressive SEO techniques
were much more effective.
Today, the situation is changing a bit, especially for AI systems. Because artificial intelligences no longer only look at “keyword density.” They try to understand whether the content is truly useful.
That's why recently:
over-inflated,
too sterile-looking,
content written in the same mold
is seen to not work 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 roughly means:
“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, they ask ChatGPT directly.
A similar situation has also started to emerge in fields such as:
finance,
software,
automotive,
health,
education
Therefore, in the upcoming period, not only Google rankings,
but also being visible in AI systems can become a serious traffic source.
Especially for sites that act early.
How Do Artificial Intelligences Evaluate a Site?
The most important part of the job actually starts here.
Because many people still continue to produce content with the old SEO logic:
unnecessarily long articles,
unreadable introductory paragraphs,
constant keyword repetitions,
inflated titles like “2026 ultimate guide.”
However, modern AI systems can distinguish most of these.
Especially because an incredible amount of AI content has emerged on the internet recently,
artificial intelligences are now paying more attention to some different signals.
For example:
does the content really 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 intelligences are actually trying to find “reliable sources” on the internet.
That's why:
a genuine brand feel,
user reviews,
natural mentions on the internet,
technical consistency,
clear contact information
are becoming important.
For example, a significant difference has started to emerge between sites opened just for SEO, providing no brand feel;
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.
Reddit's Growth to This Extent is No Coincidence
Recently, when searching for something on Google, we started seeing Reddit constantly.
The basic reason for this is actually very simple:
real user experience.
AI systems, similarly, can see:
people's natural conversations,
as more valuable than ready-made SEO texts.
Especially in queries like:
“best”
“which to buy”
“is it reliable”
“is anyone using it”
user experience has become very important.
That's why producing content alone is no longer enough. It's also important for people to naturally talk about your brand.
Technical SEO is Still Important
Sometimes when GEO is discussed, people think classic SEO is over.
Actually, quite the opposite.
Because artificial intelligences still crawl sites via the internet. So if there are technical problems, these systems cannot read your site properly either.
Especially the following topics 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.
Such 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 basically aims to tell AI systems:
“These are the important contents on this site.”
Logically, it's somewhat similar to robots.txt.
It can be useful especially for:
large blogs,
SaaS platforms,
documentation sites
But sometimes it's overemphasized on the internet.
Because adding llms.txt alone
doesn't 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 don't create miracles.
Why Do Artificial Intelligences Reference Some Sites More?
There are some common points that stand out here.
Generally, content that AI systems refer to more frequently:
is clearly written,
provides direct information,
doesn't unnecessarily elaborate,
contains definitional sentences,
provides 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 is:
short,
clear,
contextually obvious.
Content in a question-and-answer structure, 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 because it was long.
Now, user behavior is diversifying.
People now:
want quick answers,
seek clear information,
get tired of unnecessary introductions.
AI systems have also noticed this.
Therefore, in the new era:
high-information density,
readable,
content that gives a sense of real experience
may 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 generate a weak signal even 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 slightly different field.
Because here, the issue is:
quotability,
AI accessibility,
content structure,
trust signals,
technical readability.
That's why AI visibility tools have started to emerge recently.
For example,
platforms like GeoSkoru
help analyze how strong sites appear in terms of artificial intelligence systems.
Since this field is still very new,
sites that act early seem highly likely to gain a significant advantage in the next few years.
Conclusion
SEO is not ending.
But how the internet works is changing.
In the coming period, the strongest sites will probably be:
not just those optimized for Google,
but also those considered reliable by artificial intelligence systems.
Therefore, the question is no longer just:
“What is my rank on Google?”
The real question is this:
Do artificial intelligences truly find your site worthy of being referenced?
