Short answer: I bought seogeoaeo.si during the .si rush, knowing that Google reads .si as Slovenia's country-code domain. It is not on Google's list of 20 country codes treated as global, so this site starts with a location signal that points away from customers outside Slovenia. I accepted that cost on purpose. My plan is to earn links and AI citations with a free checker and published research, rather than depend on US Google rankings.
Why did I put an SEO business on a Slovenian domain?
I have worked in SEO since 2017. I know what a country-code domain tells Google. I bought seogeoaeo.si anyway, at the turn of September and October 2026, during the .si rush. I built the site on Lovable. It sells SEO, GEO and AEO services, and it hosts a free AI visibility checker.
The name did most of the work. "seogeoaeo" spells out what I sell in one string, and .si was the ending everyone was discussing. It was also cheap. The registry charges every registrar a flat 10 EUR per name, and each registrar sets its own retail price. Hostinger's .si page, for example, lists $11.99 for the first year and $16.99 a year to renew.
At the UN on 22 September 2026, Donald Trump said AI would now be called Super Intelligence, or SI. The registry's live counter showed 46,066 new .si names in September, against 3,515 in August. On 2 October it showed 250,769 .si domains in total.
The registry warns against reading all of that as a Trump effect. Its spokesperson, Klara Herman, told Foreign Policy: "The upward trend was already there before the recent attention around 'SI,'" she said, adding that the international discussion "has coincided with an exceptional additional surge in interest."
For the full background, see this explainer on what a .si domain is. This post is narrower: one builder's decision and its price.
How does Google read a .si domain?
As a site for Slovenia. Google's guide to managing multi-regional and multilingual sites says country-code domains "provide a strong signal to both users and search engines that your site is explicitly intended for a certain country."
Google does make exceptions. The same page lists the country codes it treats like .com, because "users and website owners frequently see these more generic than country-targeted". There are 20 of them, including .ai, .io, .co, .me and .tv. .si is not on the list. The list was unchanged on 2 October 2026.
The list can grow. Google's Search Central changelog records the day .ai joined: "May 30: Added .ai to the list of TLDs that Google Search treats as a global TLD (gTLD)." That was 2023. The page also says "this list may change". But Google describes no way to apply. I am not building on the hope that .si gets added.
Can I tell Google this site is not meant for Slovenia?
Not directly, and that was true even before 2022. Search Console's country-targeting setting was never a way out for a country-code domain. Google's guide offers it to generic domains only: "If your site has a generic top-level domain such as .com, .org, or any of the following domains, and wants to target users in a particular geographic location, explicitly set a country target." A ccTLD like .si was already tied to its country.
The setting itself is gone now. Google's help page on the International Targeting report says the report "has been deprecated" and that country targeting "was determined to have little value for the ecosystem, and is no longer supported." It went in 2022.
The other levers do not fix it either. Hreflang is still supported, but it tells Google which language or country version of a page to show. It does not make a ccTLD generic. This site has one version, so there is nothing to point between. Server location is on Google's list of signals, yet the same guide calls it "not a definitive signal". And Google says it "ignores locational meta tags (like geo.position or distribution)".
What does the .si actually cost this site in Google?
An unknown amount. It is not a penalty. In my reading, a .si site can still be indexed, and a strong page can still rank outside Slovenia. But for a searcher in the US, a competitor on .com starts with no country hint against them. I start with one. Google does not publish how much weight that hint carries, so nobody outside Google can put a number on it.
Here is each location signal, as Google's own pages describe it.
| Signal | What Google says | What it means for this site |
|---|---|---|
| Country-code domain | A "strong signal" of the intended country | Points to Slovenia |
| Generic ccTLD list | 20 country codes treated as global | .si is not one of them |
| Search Console country targeting | Offered for generic domains only; deprecated in 2022 | Never applied to a ccTLD like .si |
| Hreflang | Still supported | Marks versions but does not make a ccTLD generic; there is only one version |
| Server location | A listed signal | Google calls it "not a definitive signal" |
| Locational meta tags | Ignored | No help at all |
| Keyword in the extension | No advantage or disadvantage | "SI" adds no topical relevance |
Nothing in that table says the site cannot be found. It says the site starts behind wherever location matters, with no switch to change it.
What am I doing about the trade-off?
I built the plan around things a domain ending does not control.
- Not betting on US Google traffic. Rankings in US Google are not the base of this business. If that traffic arrives, it is a bonus.
- A free tool people can use. The free AI visibility checker is the main asset here. A useful free tool is the kind of page other sites link to, and a link says nothing about my domain's country.
- Published research. Posts like this one are built mostly from primary sources and quoted verbatim. The aim is to be worth citing, by people and by AI answer engines. A citation is earned by what a page says, and no AI engine has said the extension matters.
- Why a .com mirror is a bad idea. Copying the same pages onto another domain does not escape the country signal. Two near-identical copies split links and signals, and make Google choose between them.
- "SI" as a reading, not a claim. Super intelligence is a marketing reading of the name. I do not claim the extension means anything to Google beyond Slovenia.
None of this is certain to work. It moves the bet away from the one signal I cannot change and toward the ones I can work on.
Does the .si ending affect AI answers?
Partly, through Google. Google's guide to AI features and your website says: "There are no additional requirements to appear in AI Overviews or AI Mode, nor other special optimizations necessary." To be a supporting link, a page "must be indexed and eligible to be shown in Google Search with a snippet". The page says nothing about domain extensions.
Google lists no extra AI-specific requirement. But those links come from the same pool as Google Search, so any disadvantage in Google's ranking for US queries is likely to follow the page into AI Overviews and AI Mode. I cannot measure that from outside Google.
Other engines are an open question. I found no published statement from OpenAI, Perplexity or Google's Gemini, as of 2 October 2026, on whether a domain's ending affects which sources they cite. If you want the difference between ranking in Google and being cited by AI assistants, I set it out in SEO vs GEO vs AEO.
Does SI really stand for super intelligence now?
Only inside one government. On 29 September 2026 Trump signed an executive order titled "Inaugurating the Era of Super Intelligence". Section 1 says "the executive branch shall use the terms 'Super Intelligence' and 'SI' in place of 'Artificial Intelligence' and 'AI'". It applies "to the maximum extent permitted by law".
That binds the US executive branch. It does not bind Google or the .si registry. At the UN on 22 September, according to the Rev transcript, Trump said: "Let's see if I have any power. Maybe I do, and maybe I don't."
Google is also clear that the extension carries no topical weight. John Mueller wrote in a 2015 Search Central post, which now carries Google's own note that some of the information may be outdated: "Keywords in a TLD do not give any advantage or disadvantage in search." To Google, "SI" still means Slovenia. I treat the super intelligence reading as a wink in the name, and nothing more.
Should you build your own site on a .si?
It depends on where your customers search. A .si makes sense when:
- You sell to people in Slovenia. The country signal then works for you.
- You want to protect a brand name and redirect it to your main site.
- You need a short campaign address that does not have to rank.
- Your project wins on links and citations, and you accept a weaker start in country-specific Google results.
A .si is a poor choice when:
- You run a local business outside Slovenia, such as in the US or the UK, and most of your leads come from Google.
- Your site lives on organic Google traffic from one country outside Slovenia.
- You plan to copy your existing .com onto it. That only splits your signals.
One more point for brand owners. Disputes over .si names go through the registry's own process. Its general terms limit complaints to rights such as a trademark "valid on the territory of the Republic of Slovenia". A US-only trademark gives you a narrower route than it would on .com.
For seogeoaeo.si, I accepted the weaker start knowingly, because the site is built to win on the last kind of project. If you are weighing a domain for your own business, my services and prices are on the pricing page. I also publish search news and tool reviews at criticnest.com.
Frequently asked questions
Does Google treat .si as a global domain like .ai?
No. Google's documentation lists 20 country codes it treats as generic, including .ai, .io and .co. As of 2 October 2026, .si is not on that list. Google treats it as Slovenia's country-code domain, which it calls a strong signal that a site is meant for that country. Google added .ai to the list on 30 May 2023, but publishes no way to apply.
Can hreflang make a .si site rank in the United States?
Not on its own. Hreflang tells Google which language or country version of a page to show, so it helps when a site has several versions. It does not turn a country-code domain into a global one. Search Console's old country-targeting setting never applied to a ccTLD either. Google offered it only to sites on generic domains, and deprecated it in 2022.
Is a .si domain a penalty in Google?
No. It is a location signal, not a penalty. Google said in 2015 that most ccTLDs tell it a site is "probably more relevant in the appropriate country." In my reading, a .si site can still be indexed and rank outside Slovenia. The cost is that Google starts by assuming the site is for Slovenia, so it begins behind .com competitors for searches where location matters. Google does not publish how much weight that signal carries.
Do AI assistants care about a domain's extension?
No assistant has said so. Google says AI Overviews and AI Mode have no extra requirements beyond being indexed and eligible for a snippet in Search, and it does not mention extensions. Google lists no extra AI-specific requirement, though a page's Google ranking carries over. I found no published statement from OpenAI, Perplexity or Gemini on the subject.
Does the executive order make .si mean super intelligence?
Only as a reading. The order signed on 29 September 2026 tells the US executive branch to use "Super Intelligence" and "SI" in place of "AI", to the maximum extent permitted by law. It does not bind Google or the .si registry. Officially, .si is still the domain of Slovenia, and Google treats it that way.
Should I buy a .si if my customers are outside Slovenia?
As a redirect or brand protection, it can make sense, because the cost is low. As the main site for a business that needs Google traffic from the US or the UK, it is a weak choice. Google reads .si as Slovenian, and Search Console has never offered a way to change that for a ccTLD. A domain Google treats as global is the safer base.
