If you’re searching “what is Google SGE” or “Google AI Overviews,” you’re not alone — the query is climbing fast, because Google has quietly rewritten how search results work, and it changes the whole SEO game.
Here’s the first thing to clear up: the name “SGE” is already retired. Google dropped it in mid-2024 and rebranded the feature AI Overviews. Most people still say “SGE” out of habit — so this guide treats the two as the same thing.
This article answers it all in one place: what SGE / AI Overviews is, how it works, how it affects your SEO in 2026, and what to start doing today so your brand doesn’t disappear from search.
What is Google SGE? The 30-second answer
Google SGE (Search Generative Experience) is a Google feature that uses AI to generate a summarized answer at the very top of the results page, instead of just ten blue links. The user asks a question and gets a ready-made answer with source citations attached.
Google began testing SGE in 2023 inside Search Labs. In mid-2024 it renamed the feature AI Overviews, launched it in the US first, then rolled it out worldwide — reaching 200+ countries and 40+ languages by May 2025, Thailand included.
In 2026, AI Overviews is no longer an experiment — it’s the default behavior of Google Search for informational queries, with an unavoidable impact on organic click-through rates.
The 3 things you now see at the top of the SERP
When AI Overviews fires, three elements stack above everything else.
1. The AI summary box
A large panel filling the top half of the screen, containing an answer Google’s AI wrote by synthesizing multiple sources. Readable instantly, no click needed.
2. Source citations
Three to five small cards beside the box showing the sites the AI pulled from. Users can click through — or just stay in the overview.
3. Follow-up questions
Predicted next questions tacked underneath to extend the search journey — each answered by another AI Overview.
The result: the old “#1 organic result” gets pushed below the fold. On mobile, users scroll two or three screens before reaching it — which is why CTR is falling.
Where does SGE pull its answers from?
This is the most important question for SEO — if you know where the AI sources from, you know how to get picked up. Analysis from Search Engine Journal and Ahrefs across 2025–2026 points to four main content types.
Pages already ranking in the top 10
Roughly 65–75% of cited sources already rank well, though not necessarily #1. A page at position 5–8 with on-point content can still get pulled.
Pages with topical authority
Google reads the whole-site signal, not one page. Cover one topic thoroughly and it trusts you more than a site that wrote about it once.
Content with clear structure
Schema markup (FAQPage, HowTo, BlogPosting), correct heading hierarchy, and a first paragraph that answers directly all make content easier for the AI to parse.
Content with evidence
Numbers, statistics, credible links, fresh data. AI Overviews favors sources it can verify over sources that just sound confident.
Why SGE changes the entire SEO game in 2026
AI Overviews isn’t a minor tweak — it’s reshaping the business model of organic search. Three numbers make it concrete.
Zero-click searches have surged
A zero-click search is when the user gets their answer on the SERP and clicks no one’s site. SparkToro’s 2026 study finds less than one-third of Google searches still send a click — and when an AI Overview is present, the zero-click rate jumps to roughly 83%. This is the direct cause of the pattern every site sees in Search Console: impressions up, clicks flat or down.
Ranking in the top 10 is no longer enough
The old goal was “rank page 1.” The new goal is “get cited in the AI Overview.” A page ranking #5 that gets quoted can out-earn the #1 result that doesn’t — because the citation card is what users see first.
Organic CTR is dropping sharply
Seer Interactive (Nov 2025) found organic CTR on informational queries with AI Overviews fell 61% since mid-2024. Ahrefs (Dec 2025) measured a 58% drop for the #1 result. It isn’t that content got worse — the game changed.
Is SGE / AI Overviews live in Thailand yet?
Short answer: yes, since mid-2025. Google enabled AI Overviews in Thailand for Thai- and English-set accounts, and by early 2026 it’s fully rolled out in both languages. Thai-language answer quality is now far better than the beta days.
The real impact for Thai businesses: some of your competitors are already being cited in AI Overviews for queries you used to rank top-10 for. If your content isn’t structured for the AI to parse, customers read the answer that quotes your competitor — not you.
6 SEO strategies to handle SGE in 2026
Once you understand the mechanics, here’s what to actually do — the six strategies the Deemmi team uses with real clients in 2026.
1. Write content that answers the question directly
Open with the answer, not preamble. For “how much does a WordPress website cost,” start with “A WordPress site in Thailand in 2026 starts around ฿25,000…” — not “In an era of rapid change…”
2. Use schema markup the AI can read
Schema tells Google what each page is — article, question, product. Prioritize FAQPage, HowTo, Article/BlogPosting, and LocalBusiness. This is core to our SEO content service; Rank Math’s free version covers all of them.
3. Build trust with E-E-A-T
Experience, Expertise, Authoritativeness, Trustworthiness. Real author names and photos, real company details, real portfolio work, real reviews. AI Overviews reads all of it when deciding whether to cite you.
4. Heading structure the AI can parse in 5 seconds
One H1 per page, H2 for major sections, H3 for sub-points, and never skip a level. (We practice this — fixing our own hierarchy was part of refreshing this article.)
5. Long-form content that genuinely covers the topic
Ahrefs’ 2026 analysis found cited content averages 2,200–2,800 words and covers definition, mechanism, implication, action, and FAQ — the exact pattern this article follows.
6. Prepare for AEO, not just SEO
Answer Engine Optimization means optimizing so AI engines — ChatGPT, Perplexity, Gemini, Claude — recommend your brand. A growing share of buyer research now happens on AI chatbots. See our AI marketing insights for the full AEO playbook.
SGE vs AEO: what's the difference?
People mix these up. They sound alike but the scope differs.
SGE / AI Overviews is a feature of Google Search only — the AI box on Google’s SERP. Optimizing for SGE means getting Google to summarize your content there.
AEO (Answer Engine Optimization) is broader — ChatGPT, Perplexity, Gemini, Claude, Bing Chat and other assistants. Doing AEO means getting every AI engine to know and recommend your brand.
The simple version: SGE is a subset of AEO. Content optimized well for AEO is optimized for SGE by default.
Real queries that trigger AI Overviews in Thailand
Open Google now and search these — you’ll see the AI Overview box appear:
- “what is SEO”
- “how much does a WordPress website cost”
- “Google Ads vs Facebook Ads“
- “how to set up a LINE Official Account”
- “what is lead generation”
These are the queries customers run before they buy. If you’re not in the AI box, they read the answer citing your competitor.
What Thai businesses should start doing today
Three actions to start now.
1. Audit your old content
In Search Console, find pages with high impressions but low clicks — that’s AI Overviews siphoning your clicks. Restructure to answer directly, add FAQ schema, deepen coverage.
2. Add schema to every key page
FAQPage on every article, LocalBusiness on service pages, BreadcrumbList everywhere.
3. Start AEO alongside SEO
Add an llms.txt at your root, write FAQs into every pillar, add structured data everywhere you can.
Do all three this quarter and by late 2026 you’ll see your site cited more often in AI Overviews — and that citation is the moat that protects your business from zero-click search. Want help getting there? Talk to our SEO content team.
