In late September 2026, one small country’s website ending suddenly became the hot ticket on the internet. Slovenia’s .si domain saw a rush of new registrations after the US government decided to say “Super Intelligence”, shortened to “SI”, instead of “artificial intelligence”. Many buyers are now asking the same question: does the domain extension matter for SEO, and should I grab a .si, .ai or .in domain name for my business?
This post explains what happened, what Google says about domain extensions, and how to choose one for an Indian business. We checked every Google statement below against Google’s own page on 5 October 2026. The news figures come from published reports, and we name the source each time. Where something is our own view, we say so. If you are building a new site, our post on what makes a site SEO-ready covers the rest of the foundation.
Quick summary, if you’re short on time:
- The .si surge is real. Slovenia’s registry reported a 2,199% rise in .si purchases in September, according to TechCrunch.
- .si is Slovenia’s country code. Google’s page says a country-code domain is a strong signal to users and search engines that a site is meant for that country.
- Google treats some country codes, such as .ai, .io, .co, .me and .tv, like generic domains. Its list does not include .si.
- Google’s page is about which country your site targets in search results. It does not describe any extension as a ranking boost.
- For an Indian business, .in or .com are the sensible choices for a domain name. A trendy extension will not bring you visitors on its own.

What happened with .si
A domain extension, also called a top-level domain or TLD, is the ending of a web address, like .com or .in. The letters .si belong to Slovenia, the same way .in belongs to India.
Here is the timeline from published reports:
- On 22 September 2026, the US president told the UN General Assembly that the US government would use “Super Intelligence” and “SI” (CircleID).
- On 29 September 2026, an executive order told US government agencies to use the new wording in official letters, websites and reports (CircleID and TechCrunch).
- Registry SI, which runs Slovenia’s domains, reported a 2,199% increase in .si purchases in September (TechCrunch, quoting the registry’s spokesperson).
- Hostinger told TechCrunch that more than half of its .si buyers came from the US and India, and that .si cost about $12 a year against $90 for .ai.
- TechCrunch also reported that only about 3% of .si domains explicitly relate to AI. Most are unclassified.
So people are buying .si because it spells “SI”, the same letters as the new term. Whether that wording will last, or whether the buyers will ever build anything on those domains, is not known. That part is a guess, and we are not making it for you.
What Google says about domain extensions
The clearest answer comes from Google’s own page on managing multi-regional and multilingual sites. It makes four points that matter here:
- Country-code domains point to a country. Google says ccTLDs are tied to a specific country, for example .de for Germany, and so give a strong signal to users and search engines that your site is meant for that country.
- Generic domains are not tied to a place. For .com, .org and similar, Google says to set a country target yourself if you want users in one location.
- Some country codes are treated as generic. Google says it treats some vanity ccTLDs, such as .tv and .me, as generic domains, because people often see them as generic. Its list on 5 October 2026 reads: .ad .ai .as .bz .cc .cd .co .dj .fm .io .la .me .ms .nu .sc .sr .su .tv .tk .ws.
- Any other extension is generic too, unless it is a country code. Google says that unless ICANN lists a top-level domain as a ccTLD, it treats the domain as generic.
The page was last updated on 10 December 2025, and Google says its list may change. Going by the list as written, .si is not on it. That means we would expect Google to read a .si site as aimed at Slovenia. We have not tested this, and Google has not said anything about .si in particular.
One more thing about what the page does not say. It explains how an extension tells Google which country you want to reach. It does not describe any extension as a ranking boost. If someone sells you a domain by saying it ranks higher, ask them where Google said so.
Which extension should you use?
| Extension | What Google’s page says | Our view for an Indian business |
|---|---|---|
| .in | A country-code domain for India, so a strong signal that the site is meant for India | A good fit if you serve India. This is what we use for zunelo.in |
| .com | Generic. Not tied to a place, so set a country target if you need one | A safe choice if you serve several countries or want a global look |
| .ai, .io, .co, .me | On Google’s list of country codes treated as generic | Fine for a tech brand if you like the name. Check the price, which can be much higher |
| .si | Slovenia’s country code, and not on the generic list on 5 October 2026 | Not a good fit unless you serve Slovenia |
| Newer extensions like .shop or .online | Generic, as they are not country codes | Fine, but people may trust a familiar ending more. That is our opinion, not Google’s |
The short version: pick the extension that matches who you serve and what customers expect to type. For most of our Bangalore clients that is .in or .com.
Should you buy a .si domain?
For a normal business, we would not, and here is why.
- It points to Slovenia. If you serve customers in Bangalore, a Slovenian country code sends the wrong signal.
- The reason for the rush is a word choice. The demand comes from a news story about terminology. A business should not build its address on a trend that can fade.
- A domain does not bring visitors. A registration is a name, not traffic. Visitors come from useful pages, links and a good Google Business Profile.
- Prices can change. The $12 figure from Hostinger is a first-year price in a news report. Look at the renewal price before you buy any domain.
There are cases where it can make sense: you serve Slovenia, or you are deliberately buying a name as a long-term investment and understand the risk. That is a domain-trading decision, not an SEO one, and we do not give investment advice.
How to choose a domain for your business
- Start with your customers. Your domain name is the first thing they see in search results and on cards and signs. Where are they, and what would they expect to type? For Indian customers, .in and .com are familiar.
- Choose a name that is easy to say and spell. If you have to spell it twice on the phone, it is too hard.
- Keep it short and free of numbers and hyphens. This is our rule of thumb for brand names.
- Check the name is not someone else’s brand. Search for it first, so you do not end up in a dispute.
- Read the renewal price and who owns the domain. Register it in your own business name, not your web designer’s.
- Do not change a live domain just for the extension. Moving a site to a new domain is a migration project with real ranking risk. Do it only for a good reason and plan it properly.
If you are unsure which is right for your business, the choice is rarely the thing holding a site back. Our SEO services in Bangalore start with the pages and Google Business Profile, which move results far more than the ending of a web address.
Questions about domain extensions and SEO
Does the domain extension affect SEO?
It affects which country Google thinks your site is for. A country-code domain like .in is a strong signal for that country, and generic ones like .com are not tied to a place. Google’s page does not describe any extension as a ranking boost.
Is .in better than .com for an Indian business?
If you serve customers in India, .in tells Google and people that your site is meant for India. A .com also works, and it is better if you serve several countries. Pick the one your customers expect, and make sure the site is useful.
Does Google treat .ai like a country code?
No. Google’s page lists .ai among the country-code domains it treats as generic, along with .io, .co, .me and .tv. That list was last updated on 10 December 2025 and may change.
Should I buy a .si domain because of the news?
Not for ranking, and not unless you serve Slovenia. The rush came from the “SI” wording, and a domain on its own brings no visitors. If you buy one as an investment, treat it as a gamble and check the renewal price.
Will a trendy domain extension bring me traffic?
No. A domain is just an address. TechCrunch reported that only about 3% of .si domains explicitly relate to AI, which shows many were bought to hold rather than to use. Traffic comes from content, links and your Google Business Profile.
Should I change my current domain to a different extension?
Not just for the extension. Changing a live domain is a site move, and it carries ranking risk. Do it only if there is a strong reason, like a rebrand, and plan the redirects carefully with someone who has done it before.
Where this matters
The .si story is a good reminder that a domain is a choice about your audience, not a shortcut to rankings. Google’s page ties country-code domains to countries and treats a short list of vanity ones as generic. For a business in India, a clear, short .in or .com name and a site worth visiting will do more than any trending ending.
If you are planning a new website or a move, send us the address you have in mind and we will tell you what we see.
