If you've talked to a marketing vendor recently, you've probably heard three acronyms thrown around: SEO, AEO and GEO. Some will tell you SEO is dead. Others will try to sell you all three as separate packages.
Here's the plain-English version: what each one means, how they overlap, and what a small business with a limited budget should actually do.
What is the difference between SEO, AEO and GEO?
SEO gets your pages ranked in search results. AEO gets your content quoted as the direct answer. GEO gets your business mentioned and recommended inside AI-written answers. They're three layers of the same goal: being found when customers look for what you sell.
- SEO (Search Engine Optimization): Making your website rank well in Google and Bing's lists of results.
- AEO (Answer Engine Optimization): Making your content easy for tools that give direct answers, like featured snippets, Google AI Overviews and voice assistants, to pull and cite. More in our AEO guide.
- GEO (Generative Engine Optimization): Making your business show up, accurately described, when AI tools like ChatGPT, Gemini and Perplexity write recommendations. More in our GEO guide.
How do SEO, AEO and GEO compare side by side?
The clearest way to see the difference is by what each one is trying to win and which signals it leans on. Notice how much overlaps.
| SEO | AEO | GEO | |
|---|---|---|---|
| Goal | Rank a page high in results | Be the direct answer | Be mentioned and recommended |
| Where it shows up | Google/Bing results, Maps | Featured snippets, AI Overviews, voice answers | ChatGPT, Gemini, Perplexity, Copilot, AI Mode |
| Unit of focus | Pages and keywords | Questions and answers | Your business as an entity |
| Core tactics | Technical health, relevant content, links, local SEO | Question headings, answer-first paragraphs, FAQ and schema markup | Consistent facts, reviews, third-party mentions, clear "about" info |
| Typical success metric | Rankings, clicks, calls from search | Snippet/Overview appearances, question-query impressions | AI mentions, accuracy of descriptions, "found you on ChatGPT" leads |
| How much you control | Moderate | Moderate | Lower |
The overlap is the key insight. A fast site with answer-first content, solid schema markup and consistent business information helps with all three at once.
Is SEO dead in 2026?
No. SEO is the foundation the other two are built on. Many AI tools retrieve information from the web, often through search indexes, so if search engines can't crawl and trust your site, AI tools are working with less information about you too.
What has changed is the shape of the results. More questions now get an AI-written answer at the top of the page, and some people skip search engines entirely and ask a chatbot. That means:
- Ranking #1 is still valuable, but a ranking alone doesn't guarantee the click it used to.
- Informational queries ("how often should I flush my water heater?") are the most likely to be answered without a click.
- High-intent local queries ("emergency plumber near me") still lead to calls, map clicks and bookings, but AI tools increasingly shape which businesses people consider.
So SEO isn't dead. It's just no longer the whole job.
What does each one actually involve for a small business?
In practice, the work breaks down into a handful of concrete tasks, most of which serve more than one discipline. Here's how a typical small business's to-do list maps across SEO, AEO and GEO.
| Task | SEO | AEO | GEO |
|---|---|---|---|
| Fast, mobile-friendly, crawlable website | Yes | Yes | Yes |
| Complete, accurate Google Business Profile | Yes | Yes | Yes |
| Consistent name, address, phone across directories | Yes | Some | Yes |
| Service pages with question-based headings and direct answers | Some | Yes | Yes |
| LocalBusiness and FAQPage schema markup | Some | Yes | Some |
| Steady flow of detailed customer reviews | Yes | Some | Yes |
| Mentions on local news, associations, supplier sites | Yes | Some | Yes |
| Clear "about" page that defines who you are and who you serve | Some | Some | Yes |
| llms.txt file (emerging, unproven) | No | Some | Some |
If you only remember one thing from this table: the top four rows are non-negotiable, and they help everywhere.
What should a small business prioritize first?
Fix the foundation (SEO), make your best pages quotable (AEO), then build your reputation across the web (GEO). Doing them in that order avoids wasting money on advanced tactics while basics are broken.
Step 1: Foundations (SEO)
- Make sure your site loads quickly on a phone and every key page is indexable.
- Have a dedicated page for each core service, not one "Services" page listing everything.
- Complete your Google Business Profile: categories, hours, service area, photos, services.
- Make your business name, address and phone number identical everywhere.
If your current website makes any of this hard, a website refresh can be cheaper in the long run than patching an old one.
Step 2: Quotable content (AEO)
- Collect the 20 questions customers ask most often.
- Answer them on the relevant service pages: question as a heading, a direct answer in 1–3 sentences, then detail.
- Add schema markup for your business type and FAQs. See our technical AEO checklist.
Step 3: Reputation and mentions (GEO)
- Set up a consistent system for requesting reviews after every job. Review automation handles this without you remembering to ask.
- Get listed where AI tools are likely to look: industry directories, manufacturer dealer locators, local associations.
- Test what AI tools say about you monthly, and correct wrong information at the source.
How much should a small business spend on SEO, AEO and GEO?
There's no universal number, but you should not pay three times for overlapping work. Budget for one coordinated effort and judge it by leads, not acronyms.
Here's an illustrative way to think about it. Say a roofing company gets an average of $9,000 in revenue per job (this is an example figure; use your own). If better visibility in search and AI answers brings in just two extra jobs a month, that's $18,000 in monthly revenue. That gives you a sensible ceiling for what the work is worth to you, and a way to hold any vendor accountable.
A few practical guidelines:
- Be wary of separate SEO, AEO and GEO retainers from the same vendor for what is mostly the same work.
- Ask what will actually be done each month: pages written, listings fixed, schema added, reviews requested.
- Ask how they'll measure results, and accept that AI visibility is harder to measure than rankings.
- Don't forget the phones. More visibility means more calls. If you already miss calls, fix that first or in parallel. Our post on what missed calls cost home service businesses explains why.
Which businesses benefit most from AEO and GEO?
Businesses whose customers ask a lot of questions before buying, and businesses where "who should I call?" is often answered by a recommendation. That covers most local service businesses.
Some examples:
- Home services like HVAC, plumbing and roofing, where people ask about costs, urgency and repair-vs-replace decisions.
- Dental practices, where patients ask about procedures, pain, insurance and emergencies.
- Law firms, where people ask "do I need a lawyer for…" long before they call one.
- Med spas and auto repair, where trust and price questions dominate.
In each case, the business that answers those questions clearly and consistently is the one an AI tool has the most material to recommend.
Key takeaways
- SEO ranks pages, AEO gets you quoted as the answer, GEO gets you recommended inside AI responses.
- They overlap heavily. A fast site, answer-first content, schema markup and consistent business facts help with all three.
- SEO isn't dead. It's the foundation AI tools often draw on.
- Prioritize in order: foundations, then quotable content, then reputation and mentions.
- Don't pay three times for what is largely one body of work.
- Make sure you can capture the leads that better visibility brings in.

FAQ
Frequently asked questions
What is the difference between SEO, AEO and GEO?
SEO (Search Engine Optimization) helps your pages rank in traditional search results. AEO (Answer Engine Optimization) helps your content get selected as a direct answer in places like Google AI Overviews, featured snippets and voice assistants. GEO (Generative Engine Optimization) helps your business get mentioned and recommended in AI-generated responses from tools like ChatGPT, Gemini and Perplexity.
Do small businesses still need SEO in 2026?
Yes. Traditional search still drives a large share of local discovery, and many AI tools retrieve information from the same web that search engines index. A crawlable, fast, well-structured website is the foundation that AEO and GEO depend on.
Which should I do first: SEO, AEO or GEO?
Start with SEO foundations: a fast, mobile-friendly site, accurate Google Business Profile and consistent business details. Then add AEO by rewriting key pages in an answer-first format with schema markup. GEO comes last, focusing on reviews, third-party mentions and how AI tools describe you.
Do I need separate agencies for SEO, AEO and GEO?
Usually not. The three disciplines share most of the same work, and splitting them across vendors often creates conflicting advice and duplicated cost. Look for one partner who treats them as a single, coordinated effort.
Are AEO and GEO just new names for SEO?
Partly. They build on SEO fundamentals, but they reflect a real change: more searches now end in an AI-written answer instead of a list of links. That shifts the emphasis toward direct answers, structured data and consistent entity information, which classic SEO didn't always prioritize.
