AI Overviews Expand to More Than 100 Countries

If you work outside the US and wondered when Google’s AI answers would reach your market, the answer is now. AI Overviews expand to more than 100 countries this week. On 28 October 2024, Google said it had started rolling them out in over 100 countries and territories. People can also now see them in any supported language, not only the main language of their country.

For many site owners, this is the first time AI Overviews will show up for their audience. Below I explain what Google announced, what changed for links and ads, where AI Overviews are still missing, and the checks I would run on your site this week.

What Google Announced on 28 October 2024

Google shared the news in a post on its Keyword blog. It calls this the biggest expansion of AI Overviews so far. Here are the main points from Google’s announcement:

• More than 100 countries and territories. The rollout started this week and adds a large number of new markets.
• More than 1 billion users a month. Google says AI Overviews will now reach over 1 billion people globally every month.
• Any supported language, in any launched country. The supported languages include English, Hindi, Indonesian, Japanese, Portuguese and Spanish.
• Better link display. The right-hand link panel on desktop, and site icons you tap on mobile, are part of the experience. In-line links inside the AI text launched earlier this month.
• Ads stay in their own labelled slots. Ads inside AI Overviews are available on mobile in the US for relevant queries.

Google also repeats its claim that people prefer Search with AI Overviews and find the results more helpful. That is Google’s own view. I treat it as a statement of direction, not as proof that your traffic will be fine.

A Quick Timeline of AI Overviews So Far

It helps to see how fast this has moved. In under two years, Google went from a test to a feature for over a billion people.

1. May 2023: Google shows the Search Generative Experience (SGE) at I/O and opens it as an opt-in test in Search Labs.
2. May 2024: SGE becomes AI Overviews and launches for everyone in the US. I covered the impact in AI Overviews launch in the US and what it means for clicks. Two weeks later, Google explained and fixed some odd AI Overviews answers.
3. August 2024: AI Overviews reach six more countries: the UK, India, Japan, Indonesia, Mexico and Brazil, each with local language support.
4. Early October 2024: Google launches in-line links inside the AI text and brings ads into AI Overviews on mobile in the US.
5. 28 October 2024: The expansion to more than 100 countries and territories begins.

So before this week, AI Overviews showed by default in only seven countries. Now they cover most of the world’s search users outside Europe.

Which Countries Get AI Overviews Now

The new list covers three broad regions. Google groups them as the Americas, Asia-Pacific, and Europe, the Middle East and Africa.

• Americas: the US, Canada, Mexico and Brazil, plus many countries in Central America, South America and the Caribbean.
• Asia-Pacific: India, Japan, Indonesia and Australia, along with many other countries and Pacific island nations.
• Europe, Middle East and Africa: the UK and many African countries.

If you serve customers in Canada or Australia, this is a big change. Until now, your audience saw normal results while US users saw AI answers on top. That gap is closing.

Why the EU Is Still Missing

No European Union country is on the list. Google has not given a detailed public reason in its post. The EU has strict rules on digital platforms, data and AI, and big tech companies have often launched AI features there later than elsewhere.

I would not guess at a date. If your main market is Germany, France, Spain or another EU country, your Google results will not show AI Overviews yet. Still, I would prepare now, because the pattern so far is that Google expands step by step.

The Language Change Matters More Than It Looks

Before this update, each country mostly got AI Overviews in its main language. Now, a user in any launched country can see them in any supported language. Google’s own example is a Spanish speaker in the US who can now get AI Overviews in Spanish.

This matters if you publish in more than one language. A Hindi page can now appear in an AI Overview for a Hindi search made in the UK, the US or Canada. In my experience, sites with bilingual audiences often underinvest in their second language. This update gives those pages a reason to be good.

What AI Overviews Expanding to 100+ Countries Means for SEO

The honest answer is that it depends on your queries. AI Overviews do not show for every search. They show most often for questions where Google thinks a summary helps, such as “how”, “why” and “what is the best way to” searches.

Here is how I think about the effects for different kinds of sites.

Informational Content Is Most Exposed

If your traffic comes from simple fact questions, an AI summary can answer the user before they click. Definitions, quick how-tos and “what is” posts are the most at risk. I would expect clicks on these pages to change first.

Pages that need a real visit hold up better. Think of tools, calculators, detailed comparisons, local service pages and product pages. A summary rarely replaces those.

Being a Cited Source Is the New Goal

AI Overviews show links to the pages they draw from. Google said in May 2024 that links inside AI Overviews get more clicks than if the same page had appeared as a normal result for that query. Google also says the newer link designs have increased traffic to supporting websites.

I can’t verify those claims for every site, and Google has not published the numbers behind them. But the logic is clear: if an AI Overview shows for your main queries, you want to be one of the linked sources, not missing from the box.

Local and Small Businesses in New Markets

For a small business in Canada, Australia or India, the first change you may notice is fewer clicks on blog posts that answer simple questions. Your Google Business Profile and local pages should matter just as much as before, because a summary can’t book a table or send a plumber.

I’d focus on the pages that make money, not the ones that only bring visits.

Ads Are Moving Into the AI Space Too

Google says ads will keep appearing in clearly labelled slots. For now, ads inside AI Overviews are only on mobile in the US. If you run Google Ads in other countries, nothing changes there yet. Still, I would watch how paid and organic clicks shift on queries that start showing AI Overviews.

How to Check If AI Overviews Affect Your Site

Search Console has no separate report or filter for AI Overviews. Clicks and impressions from them are mixed into your normal web search data. So you need to work it out with a few simple checks.

Here is the process I use:

1. Pick your newly affected countries. In the Search Console Performance report, filter by country. Start with your biggest markets that were added this week, such as Canada or Australia.
2. Set a clean comparison. Compare the weeks after 28 October with the weeks before. Use the same days of the week, and keep in mind that the rollout happens over time, not all at once.
3. Find question queries. Use a query filter with a regex such as ^(how|what|why|when|can|does|is)b to find question searches. These are the ones most likely to trigger an AI Overview.
4. Look for “high impressions, falling CTR”. If impressions stay steady but click-through rate (the share of people who click after seeing your result) drops, an AI answer above you is a likely reason.
5. Check the results by hand. Search your top queries from that country. A VPN set to that country helps here. Note whether an AI Overview appears and whether your page is linked.
6. Record what you find. Keep a simple sheet with the query, the date, whether an AI Overview showed and which sites were cited. AI Overviews change often, so dated notes are useful later.

When I do this, I always look at country data separately. A drop in the US mixed with steady traffic from new markets can hide what is really going on.

What GA4 Can and Can’t Tell You

In GA4, visits from AI Overview links show up as normal Google organic traffic. There is no special source for them. So GA4 can show you the trend for a landing page, but not whether the click came from the AI box or a blue link.

I pair GA4 landing page data with the Search Console checks above. If a page loses organic sessions only in a newly launched country, and only for question queries, that is a strong hint.

How to Improve Your Chances of Being Cited

Google has not given a special checklist for AI Overviews. It says the same Search systems decide which pages are useful. That means normal SEO still does the heavy lifting. Here is what I focus on.

• Answer the question early. Put a clear, direct answer near the top of the page, then add depth below. This helps both readers and Google.
• Cover the follow-up questions. AI Overviews often pull from pages that explain the next step, not just the first answer.
• Show real experience. Explain how you actually do the task, what goes wrong and what you would skip. Thin rewrites of other pages rarely stand out.
• Keep pages easy to crawl. The main content should be in the HTML, load fast and not hide behind tabs that need clicks to load.
• Use clear headings. Headings that match real questions make it easier for anyone, human or machine, to find the right section.
• Update key facts. Prices, dates and steps go out of date. Old facts are a common reason a page loses trust.

One mistake I usually see is rewriting pages to sound like an AI summary. That makes your page less useful, not more. If your page reads exactly like the AI answer, there is little reason to click it.

Local Language Pages Need the Same Care

Because users can now see AI Overviews in any supported language, your translated pages compete in more places. Check that they are proper translations, not rough machine output. Make sure each version has the right hreflang tags (code that tells Google which language and country a page is for).

Can You Opt Out of AI Overviews?

There is no special tag that removes your site from AI Overviews only. AI Overviews are part of Google Search, so the normal search controls apply. Google has said its preview controls also work for AI Overviews:

• nosnippet stops Google from showing any snippet from the page, in AI Overviews and in normal results.
• data-nosnippet lets you mark specific parts of a page that Google should not use in snippets.
• max-snippet limits how many characters Google can use in a snippet.

All three also affect your normal search listings. In my experience, most sites should not use them for this reason. You would trade a small risk of fewer AI-driven clicks for a weaker listing everywhere.

The Google-Extended token in robots.txt is a different thing. It controls whether your content helps train Gemini and Vertex AI models. Google says it does not affect Google Search, so it will not remove you from AI Overviews. I explained it in more detail in my guide to Google-Extended.

Can Users Turn AI Overviews Off?

Users cannot switch AI Overviews off in their settings. They can choose the “Web” filter under the search box, which shows only text links. Some will, but I would not count on many people doing it. Most users take the page as Google shows it.

What I’d Do This Week

If your audience is in one of the newly launched countries, here is my short list. None of it is urgent, but all of it is useful.

1. Note the date: 28 October 2024. Add an annotation in your reports so you can explain changes later.
2. List your top 20 pages by organic clicks in each new market.
3. Check which of their main queries now show an AI Overview, and whether you are cited.
4. Improve the top pages where you are not cited but a competitor is. Start with the opening answer.
5. Review your translated pages if you have them.
6. Set a reminder to compare data again in a month, once the rollout has settled.

If you tested Search Generative Experience back in 2023, a lot of this will feel familiar. My first look at SGE in Search Labs covers how the early version worked and how it has changed.

Conclusion

AI Overviews expanding to more than 100 countries makes Google’s AI answers a normal part of search for most of the world outside the EU. The language change means multilingual sites feel it too. For marketers in Canada, Australia, Latin America, Africa and much of Asia, the impact is no longer a US story.

My advice is simple: measure by country, focus on question queries, and work on being the source that AI Overviews link to. Your next step is to run the Search Console checks above for your biggest new market, then compare the results again in a few weeks.
