Short answer
SEO earns your site a place in Google's normal results; AEO gets your content quoted in AI answers from Google, ChatGPT or Perplexity. Ads buy a sponsored place that works from day one and stops when the budget does, while SEO and AEO take months, then keep working. Most businesses should use them together.
Key points
- Google handled 99.48% of searches in Thailand in August 2026, so Thai SEO effectively means Google.
- People shown an AI summary clicked a result 8% of the time, against 15% with ordinary results.
- Brands cited in AI Overviews got 35% more organic and 91% more paid clicks than brands that were not.
- Only 1.74% of new pages reach Google's top 10 within a year; give SEO at least six months.
- Judge SEO, AEO and ads by enquiries and sales, not by traffic.
What is SEO?
SEO is the work of getting Google to find your page, read and store it (indexing), and rank it well for the searches your buyers type. Every page goes through those three steps before it can appear; SEO is making each of them go your way.
In practice it has three parts. Technical: the site loads fast, works on mobile, and Google can fetch and understand every page. Content: pages that answer the questions buyers actually type, in the words they use. Authority: other reputable sites linking to or mentioning you, which tells Google your pages are worth ranking.
In Thailand, SEO effectively means Google. According to StatCounter, Google handled 99.48% of searches in Thailand in August 2026, with Bing at 0.45%.
What is AEO, and how does it differ from SEO?
AEO is making your page one of the few that AI tools quote when they answer a question. More and more questions are answered before anyone clicks: Google shows an AI Overview at the top of many results, and people ask ChatGPT or Perplexity instead of searching. These tools read many pages and quote a few.
What gets a page quoted is fairly consistent: it answers the question in its first sentence rather than building up to it, it uses headings phrased as the questions people ask, it states specific facts and numbers, it marks up FAQs and business details in structured data, and your company's information is consistent across the web.
AEO does not replace SEO; it sits on top of it. AI answers draw heavily on pages search engines have already found and indexed, so a page Google has never fetched is unlikely to be quoted anywhere.
How much have AI answers cut search clicks?
Fewer searches end in a click than ever. SparkToro's study of US Google searches from January to April 2026 found that 68% ended without a click to any result, up from about 60% in 2024.
AI summaries are a large part of that. In Pew Research's 2025 study of real browsing, people who saw an AI summary clicked a result in 8% of visits, against 15% for people who saw ordinary results, and clicked a link inside the summary itself only 1% of the time.
Ads are not immune. Seer Interactive tracked informational searches from mid-2024 to September 2025: where an AI Overview appeared, organic click-through fell 61% and paid click-through fell 68%. The same data holds the opportunity: brands cited inside the AI Overview earned 35% more organic clicks and 91% more paid clicks than brands that were not. Being the quoted source is now worth more than being the tenth blue link.

How are ads different from SEO?
Ads are rented: fast, targetable and easy to measure, but the traffic ends the moment the spending does. Search ads on Google capture people who are already looking, and you pay each time someone clicks. Social ads on Facebook, Instagram or LINE interrupt people who were not looking, which makes them better at creating demand than catching it.
The price of a click is set by auction, so it rises as more competitors bid on the same words. Businesses that rely only on ads tend to see the cost of each customer creep up, while businesses that also rank organically can lean less on paid clicks for the searches they already win.
Ads alone, SEO alone, or both: which works better?
Both, for most businesses, because the combined line is never empty. The chart shows the typical shape, not a forecast. Ads alone buy a steady flow of visitors from the first month and stop completely when the budget stops after month 12. SEO alone starts near zero, grows as pages get indexed and climb, and keeps coming after the heavy spending ends. Using both means running the same ads through the first year while SEO builds, then keeping a smaller ad budget for the searches SEO has not won yet.
Ads cover the months when SEO is still slow, and SEO carries more of the load once it arrives. It costs more in the first year than either alone, but it avoids both ways this usually goes wrong: a year of waiting on SEO with no customers, or a business that stops being found the day the ad budget runs out.
The slow start is real. Ahrefs' 2025 study found that only 1.74% of newly published pages reach Google's top 10 within a year, and that the average top-10 page is more than two years old. We see the same on our own site, where Google took weeks to fetch new guides at all. The payoff is real too: organic visitors cost nothing extra per click, so their cost falls every month they keep arriving.
- Ads alone, 12 months
- SEO alone
- Both: ads in year one, then a smaller ad budget, plus SEO
How do SEO, AEO and ads compare side by side?
Each wins on different rows and none wins them all. Read the rows that matter for your business first.
| SEO | AEO | Ads | |
|---|---|---|---|
| What you get | A place in Google's normal results | Your content quoted in AI answers | A sponsored place at the top |
| How you pay | Work on the site and content | Work on the site and content | Per click or per view |
| First results | Months | Months, after SEO | The same day |
| When you stop paying | Keeps working for a long time | Keeps working while the page stays relevant | Stops immediately |
| Cost over time | Front-loaded, then falls per visitor | Front-loaded, then falls per visitor | Steady or rising as competitors bid |
| How it appears | An ordinary result | A quoted source inside the answer | A result marked Sponsored |
| Control | You shape the page; Google decides the rank | You shape the page; the AI decides what to quote | You choose words, audience and budget |
| Targeting | By what people search | By what people ask | By keyword, place, time and audience |
| Measurement | Search Console, analytics, with a lag | Hard to measure; citations and brand searches | Exact, per click |
| Biggest risk | Slow, and results are never guaranteed | The newest and least predictable | Rented traffic, rising click prices |
| Best for | Questions and services buyers search every month | Questions people ask an assistant before choosing | Launches, promotions, and filling the gap while SEO builds |
How ads and SEO help each other
Each makes the other work better; running both is more than two channels side by side.
- Ads show you what converts. The search terms report lists the searches that led to enquiries, which tells you which SEO pages to write first
- SEO pages make ads cheaper. Google's Quality Score weighs landing-page experience, so a page that properly answers the searcher's question can lower what each click costs
- Showing up twice wins more clicks. Seer Interactive found that brands cited in AI Overviews earned 91% more paid clicks and 35% more organic clicks than brands that were not
- Ads fill the gaps SEO cannot reach: new services, short promotions, and competitive searches you may never rank for
- Readers become an audience. People who read your guides can be reached again with Facebook, Instagram or LINE ads
- Budget moves as rankings arrive. Test pausing ads on searches where you rank in the top three, check whether total clicks hold, and move that money to the next gap
Why does a business website need SEO and AEO?
Because when a buyer searches for the service you sell or the problem you solve, someone's page answers. If it is not yours, it is a competitor's, and increasingly an AI assistant repeats that competitor's answer as if it were simply the facts.
Thai-language search is also less crowded than English. In our own keyword research we keep finding Thai buyer questions that no business in the field has answered properly, while the same question in English has dozens of good pages. A clear Thai page that answers such a question can rank and get quoted with far less competition.
Search is only the first step. The page still has to turn a reader into a conversation, so make the next step obvious, whether that is a LINE chat, a call or a form.

Which AEO tools track AI citations?
AEO tracking is young. Google and Microsoft only started reporting AI visibility in 2026, and the dedicated trackers work by asking AI assistants large sets of questions and recording who gets cited. Use the free reports first, and treat the paid trackers' numbers as samples rather than totals.
| What it does | Cost | |
|---|---|---|
| Search Console generative AI report | Impressions in AI Overviews and AI Mode by page. Rolling out gradually since June 2026, with no click data yet | Free |
| Bing Webmaster Tools AI Performance | How often Microsoft Copilot and Bing AI summaries cite your pages, and for which queries | Free |
| Rich Results Test and Schema Markup Validator | Checks the structured data (FAQ, organisation, product) that helps search and AI understand a page | Free |
| Semrush AI Visibility Toolkit | How often your brand appears in AI assistant answers, compared with competitors | Paid |
| Ahrefs Brand Radar | Brand mentions across AI answers, compared with competitors | Paid |
| Profound, Peec AI, Otterly.AI | Dedicated trackers for citations in ChatGPT, Perplexity, Gemini and Google AI answers; Otterly is the most accessible for small businesses | Paid |
| Asking the assistants yourself | Put your buyers' real questions to ChatGPT, Gemini and Perplexity each month and note who gets cited | Free |
Which ad tools matter in Thailand?
In Thailand the ad platforms that matter most are Google, Meta and LINE, with TikTok for younger audiences. The tracking tools matter as much as the ad platforms: without conversion tracking, every platform optimises for clicks instead of customers.
| What it does | Cost | |
|---|---|---|
| Google Ads | Search, YouTube and display ads; you bid on the searches you want to appear for | Pay per click or view |
| Google Keyword Planner | Search volumes and suggested bids for keywords, inside Google Ads | Free with a Google Ads account |
| Meta Ads Manager | Facebook and Instagram ads, targeted by interest, location and your own customer lists | Pay per result |
| LINE Ads | Ads inside the LINE app, such as LINE VOOM and LINE TODAY, where most Thai customers already are | Pay per result |
| TikTok Ads Manager | Short video ads on TikTok | Pay per result |
| Google Tag Manager | Adds tracking tags, such as enquiry and purchase events, without editing the site each time | Free |
| Meta Pixel and Conversions API | Reports enquiries and sales back to Meta so its ads optimise for customers, not clicks | Free |
| Looker Studio | Dashboards that combine Google Ads, Analytics and Search Console data in one view | Free |
Doing SEO yourself, hiring an agency, or a website built SEO-ready by SyncEdge?
Many small businesses can start SEO themselves. The free Google tools above show what you appear for and what to fix, and writing pages that answer buyers' questions takes knowledge of your business more than specialist skill. An SEO agency earns its fee on the ongoing work: content, links and reporting, month after month.
What is hard to fix from either side is a website whose foundation was wrong from the start. That is the part we do: technical SEO is built into every website we make, with clean URLs, schema markup, Core Web Vitals work and a sitemap finished before launch. Content strategy and ongoing SEO are a separate service. The three combine well, and many businesses have the site built right once, then write content themselves or with an agency.
| Do it yourself | SEO agency | SyncEdge | |
|---|---|---|---|
| Technical foundation | As far as your website platform and theme allow | Audits the site and lists the fixes; making them may need whoever built it | Built into the website before launch: clean URLs, page structure and a sitemap |
| Speed and Core Web Vitals | Checked with PageSpeed Insights, fixed as far as your platform lets you | Usually part of the audit, with fixes handed to whoever maintains the site | Worked on during the build; on WordPress projects the target is a Lighthouse performance score above 90 at launch |
| Structured data for AEO | Plugins such as Yoast SEO or Rank Math cover the basics on WordPress | Commonly reviewed or added as part of the service | Schema markup built into the pages from the start |
| Content | You write it, and you know your buyers' questions best | Their core work: keyword research, briefs and articles every month | Content strategy is a separate service; the site is ready for whoever writes |
| Links and authority | Slow to build alone: Google Business Profile, directories, partners | A main part of the work for many agencies | Not part of the website build |
| Measurement | Search Console and Analytics 4, both free | Regular reports on rankings, traffic and leads | A sitemap ready for Search Console at launch; ongoing reporting sits with the separate SEO service |
| Cost pattern | Your time, plus paid tools if you need them | Usually a monthly fee | The website project, with technical SEO included, then a maintenance retainer if you want one |
| Best for | Small businesses starting out on a website that already works well | Businesses ready to invest in content and links every month | A new website, or one whose foundation is holding its content back |
Where should you start with SEO and AEO?
Fix the foundation first: the site loads quickly on a phone, every service has its own page, Google can crawl and index all of them, and your business details are the same everywhere. Without this, content and ads both underperform.
Then write for the questions buyers ask: one page per real question, answer first, in the words they type. Ten pages that answer ten real questions beat fifty that repeat the same claims.
Use ads where speed matters: on a handful of high-intent searches where one customer is clearly worth the click, and during launches. As organic pages start to rank, move budget away from the searches you now win for free. Judge all of it by enquiries and sales, not by traffic, and give SEO at least six months before deciding whether it works.
Before you spend on SEO or ads
- Does every service you sell have its own page?
- Has Google indexed those pages? Search Console will tell you
- Do your pages answer the questions buyers ask, in the words they use?
- Does each page answer its question in the first sentence?
- Are your business name, address and contact details the same everywhere online?
- Is the next step after reading obvious: LINE, a call or a form?
- Are you measuring enquiries and sales, not just visitors?
- Which searches are worth paying for now, while SEO builds?
Frequently asked questions
What is SEO?
SEO, search engine optimisation, is the work that gets your website shown in Google's normal results without paying per click. It covers three things: technical work so Google can find and understand your pages, content that answers what buyers search, and authority from other sites linking to or mentioning you.
What is AEO, and how is it different from SEO?
AEO, answer engine optimisation, is getting your content quoted when AI tools such as Google's AI Overviews, ChatGPT or Perplexity answer a question directly. It builds on SEO rather than replacing it: pages that answer the question in the first sentence, use question headings, state specific facts and carry structured data are the ones AI answers tend to quote.
How long does SEO take to work?
Usually months, not weeks. Ahrefs found that only 1.74% of new pages reach Google's top 10 within a year, and that the average top-10 page is over two years old. Technical fixes can show within weeks; content and authority take longer. Give it at least six months before judging.
Should we use ads and SEO together?
Yes, for most businesses. Ads alone are the fastest way to get visitors, but traffic stops when the budget does and click prices rise as competitors bid. Together, ads bring customers while SEO is still slow and show which searches convert, so you know which pages to write first; as those pages rank, you move ad budget off the searches you now win for free.
Is SEO still worth it now that AI answers questions directly?
Yes, but the goal has shifted from ranking alone to being the source that gets quoted. Clicks from search are falling, with or without AI Overviews, but Seer Interactive found that brands cited inside AI Overviews got 35% more organic clicks and 91% more paid clicks than brands that were not.
How do we measure whether SEO is working?
Watch three things in order: whether Google has indexed your pages, which searches they appear for and at what position in Search Console, and how many enquiries and sales come from organic visitors. Traffic alone can rise without a single new customer, so tie it to leads.
Which tools do we need to start SEO?
Four free Google tools cover most of what a small business needs: Search Console for what you rank for and what Google has indexed, Analytics 4 for visitors and enquiries, Business Profile for Google Maps, and PageSpeed Insights for loading speed. Add a paid suite such as Ahrefs or Semrush once you are researching keywords and competitors regularly.
