AEO vs GEO vs SEO for Small Business: What’s the Difference
Updated: 5 days ago
By Editorial Team · Updated September 2, 2026 · 12 min read
Google's guide to generative AI search, last updated July 10, 2026, settles the acronym debate in one sentence: optimizing for generative AI search "is optimizing for the search experience, and thus still SEO." For Google's own AI features, that's the end of it. For ChatGPT, Perplexity, and Copilot, which run their own crawlers and lean on different sources, it's most of the story but not all of it. SEO, AEO, and GEO are three names for overlapping jobs on one website, not three services to buy separately. SEO gets your pages crawled, indexed, and ranked. AEO (answer engine optimization) makes a page's answer easy for AI Overviews, featured snippets, and voice assistants to lift. GEO (generative engine optimization) gets your business named or cited inside AI-generated answers on ChatGPT, Gemini, Perplexity, and Google AI Mode. A small business should run all three as one plan, in that order, because the SEO foundation feeds both of the others.
The Short Version
Verdict: don't buy three services. Buy one plan that covers three jobs, starting with the foundation. Get your pages indexed and give every service its own page (SEO). Put the answer to each buyer question in the first two sentences under a clear heading (AEO). Then earn mentions, reviews, and consistent listings on sites you don't own, and let AI search crawlers reach your site (GEO). Measure each job with a different free scoreboard: Search Console for rankings and Google's AI features, Bing Webmaster Tools for Copilot citations, and a monthly prompt log for ChatGPT and Gemini. Skip llms.txt projects and "AI schema" packages. Google says you don't need them.
Key Takeaways
Quick answer: the three jobs share one foundation, differ mainly in where the answer appears and what you can control, and need separate measurement.
Google calls AEO and GEO "still SEO." Its July 2026 guide says you don't need "new machine readable files, AI text files, markup, or Markdown" to appear in its AI features.
Questions trigger AI answers. In Seer Interactive's 2026 study of 5.47 million queries, question-format searches triggered AI Overviews 85.9% of the time, and comparison searches 95.4%.
Being cited pays. The same study found brands cited in an AI Overview earned 120% more organic clicks per impression than when they weren't cited.
GEO is the hardest of the three. SOCi's 2026 index found ChatGPT recommended 1.2% of local business locations, against a 35.9% average rate of appearing in Google's local 3-Pack.
The demand is real. Use of ChatGPT and other AI tools for local business recommendations rose from 6% to 45% in a year in BrightLocal's 2026 survey of 1,002 U.S. adults.
What Do SEO, AEO, and GEO Mean for a Small Business?
Quick answer: SEO is getting your pages found and ranked in search results. AEO is shaping a page so an engine can lift its answer word for word. GEO is getting your business named or cited when an AI tool writes its own answer. Same website, three different finish lines.
Term | The job | Where it shows up | What winning looks like | Main lever |
SEO (search engine optimization) | Get pages crawled, indexed, and ranked | Google and Bing results, and the map pack for local SEO | Your page ranks for a buyer's search and gets the click | Crawlable pages, one page per service, links, reviews |
AEO (answer engine optimization) | Make a page's answer easy to lift whole | AI Overviews, featured snippets, People Also Ask, voice assistants | Your sentence becomes the answer shown | Answer-first sections, question headings, specifics such as prices and areas |
GEO (generative engine optimization) | Get the business named or cited inside a generated answer | ChatGPT, Gemini, Perplexity, Copilot, Google AI Mode | Your business is on the AI's shortlist | Mentions, reviews, consistent listings, crawler access |
The terms have different histories. AEO grew out of the featured-snippet and voice-assistant years, when the goal was to be the one answer Google or Alexa read out. GEO was introduced in a 2023 research paper by Pranjal Aggarwal and colleagues, accepted to the KDD 2024 conference, which found that GEO methods "can boost visibility by up to 40% in generative engine responses" on the authors' benchmark (arXiv). You'll also see AIO, LLMO, and "AI SEO." They describe the same territory. If a proposal uses four acronyms, ask what work sits behind each one.
Is AEO or GEO Different From SEO? What Google Says
Quick answer: on Google, no. Google says its AI features run on its core search systems and that optimizing for them is still SEO. Outside Google, partly: ChatGPT, Perplexity, and Copilot use their own crawlers, indexes, and data partners, so GEO adds work that classic SEO never covered.
Google's position is unusually direct. Its guide names both acronyms and concludes that optimizing for generative AI search "is optimizing for the search experience, and thus still SEO" (Google Search Central). The same guide says "There's no requirement to break your content into tiny pieces for AI to better understand it" and "You don't need to write in a specific way just for generative AI search." What Google does describe is "query fan-out," where its AI runs "a set of concurrent, related queries" to gather more results. That's why complete pages that answer the follow-up questions a buyer would ask do well in AI Mode.
The difference becomes real once you leave Google:
ChatGPT runs its own search crawler (OAI-SearchBot) and uses licensed data, including Yelp's business listings for local results.
Perplexity runs its own search index and crawler.
Copilot answers from Bing and Bing Places.
Gemini leans on Google Search and Google Maps data.
Share is shifting between them, too. Comscore data reported by Yahoo Finance showed ChatGPT's share of AI prompt volume falling from 70% to 50% between January and June 2026, while Gemini rose from 17% to 30% and Claude from 2% to 11% (Yahoo Finance). For a small business, GEO mostly means being easy to find and confirm across several systems at once, not tuning for one.
It also means a first-page ranking is no guarantee. Our guide to why a business can rank on Google but not get cited by AI explains the most common causes of that gap.
Where the Three Jobs Overlap, and Where They Split
Quick answer: most of the work is shared. Crawlable pages, one page per service, and a complete Google Business Profile serve all three jobs. AEO adds answer-first writing. GEO adds the work that happens off your website: mentions, reviews on several platforms, consistent listings, and access for non-Google crawlers.
Task | SEO | AEO | GEO |
Pages indexed in Google and Bing | Core | Core | Core |
One page per service, with prices and areas served | Core | Core | Core |
The answer in the first two sentences under each heading | Helps | Core | Core |
Headings phrased the way buyers ask | Helps | Core | Helps |
Backlinks from relevant sites | Core | Helps | Helps |
Mentions of your business on other sites, linked or not | Helps | Little effect | Core |
Reviews on Google, Yelp, and your industry's directories | Core for local | Little effect | Core |
The same name, address, phone, and hours on every listing | Core for local | Little effect | Core |
Allowing AI search crawlers such as OAI-SearchBot and PerplexityBot | Little effect | Little effect | Core |
Updating key pages with real changes | Helps | Helps | Core |
Two studies explain why the GEO column leans so heavily on work away from your site. In Ahrefs' study of 75,000 brands, branded web mentions correlated with AI Overview visibility at 0.664, against 0.218 for backlinks (Ahrefs). And Seer Interactive found that 75% of the pages AI tools cite were updated within the previous year (Seer Interactive). An AI tool that's deciding whether to name you looks for other people confirming you exist and for signs you're current.
How Do You Measure SEO, AEO, and GEO?
Quick answer: each job has its own scoreboard. Use Search Console's Performance report for SEO, its generative AI report for Google's AI features, Bing Webmaster Tools for Copilot citations, analytics for ChatGPT referrals, and a monthly prompt log for everything else.
Job | Free tool | What it tells you | Its limit |
SEO | Google Search Console, Performance report | Queries, clicks, and average position | Doesn't separate AI answers |
AEO and GEO on Google | Search Console generative AI report, rolled out to all sites on August 31, 2026 | Impressions from AI Overviews and AI Mode, by page | Impressions only, with no queries or clicks, and small sites may not have enough data |
GEO on Microsoft | Bing Webmaster Tools, AI Performance | Citations in Copilot and Bing AI answers, citation share, topics, and intents | Microsoft surfaces only |
GEO on ChatGPT | Google Analytics or Wix Analytics | Visits tagged utm_source=chatgpt.com | Misses people who call or search your name instead of clicking |
GEO everywhere | A monthly prompt log: the same 10 buyer questions, run in each assistant on the same day | Who gets named and which sources are shown | Manual, and answers vary from run to run |
GEO on a Wix site | Wix AI Visibility Overview | Mentions and citations for up to 50 questions across ChatGPT, Gemini, and Perplexity | Uses Wix AI credits and needs 50 unique visitors in the last 30 days |
Record a baseline this month before you change anything. A single screenshot of an AI answer proves very little, because the same question can produce a different answer an hour later. Twelve months of the same questions, asked the same way, is a trend you can act on.
Which Should a Small Business Do First?
Quick answer: SEO first, AEO second, GEO third, because each job depends on the one before it. An AI tool can't cite a page it can't find, and it rarely names a business nobody else mentions.
Foundation (SEO). Make sure your pages are indexed, give every service its own page with prices and areas served, and complete your Google Business Profile. Done looks like: every revenue-driving service has a page, and each page appears in Search Console.
Answers (AEO). Rewrite the top of each key page so the answer to the buyer's question comes first, then add the questions you hear on calls as short FAQs. Done looks like: a stranger can read the first two sentences of any page and know what you do, where, and roughly for how much.
Mentions (GEO). Align your listings on Google, Yelp, Bing Places, and Apple Business, earn reviews on more than one platform, allow AI search crawlers, and pursue two local mentions a quarter. Done looks like: your business shows up in your monthly prompt log for at least some of your buyer questions.
Not every business starts at step 1. Use your situation to find the job that's holding you back:
If this sounds like you | Start with |
You sell more services than your site has pages | SEO: build the missing service pages |
AI Overviews appear for your buyer questions but quote someone else | AEO: rewrite your openings so the answer comes first |
Your pages rank, but AI assistants never name you | GEO: listings, reviews, and mentions on other sites |
AI tools describe you with old hours, prices, or services | GEO: fix every listing so it matches your website |
All three are in place and you want more | GEO: local press, best-of lists written by others, and industry directories |

What All Three Jobs Look Like in a Real Month
Quick answer: once the foundation is built, about 8 hours a month covers all three jobs for a typical local business: roughly 2.5 hours of SEO upkeep, 2 hours of AEO rewriting, and 3.5 hours of GEO work on reviews, listings, and mentions.
Most owners don't need to know which acronym they're working on. They need to know what to do this week. Here's how the three jobs fit into one month:
When | Job | Task | Time |
Week 1 | SEO | Check Search Console's Pages report for errors, and update your Business Profile hours and photos | 1.5 hours |
Week 1 | GEO | Run your monthly prompt log and note who got named | 1 hour |
Week 2 | AEO | Rewrite the opening of one service page so the answer comes first, and add one real FAQ from a recent call | 2 hours |
Week 3 | GEO | Ask recent customers for honest reviews, reply to every review, and fix one listing that doesn't match | 1.5 hours |
Week 4 | GEO | Pitch one local mention: a chamber directory, a supplier's installer page, or a neighborhood association | 1 hour |
Week 4 | SEO | Refresh one older page with current prices, new photos, and a dated note on what changed | 1 hour |
The balance shifts over time. In the first months, most of the hours go to foundation work. Once every service has a strong page, the hours move toward reviews and mentions, because that's where most AI visibility is won.
AEO and GEO Tactics That Waste Your Budget
Quick answer: skip llms.txt projects, FAQ schema sold as an AI lever, content chopped into tiny chunks, rewrites done "for AI," hidden prompts in "Summarize with AI" buttons, and anyone guaranteeing AI placement. Google says the first four aren't needed, and the last two can backfire.
Tactic | Why to skip it |
Paying for an llms.txt file | Ahrefs found 97% of llms.txt files received zero requests in May 2026 across 137,000 domains, and Google says you don't need "AI text files" to appear in its AI features |
FAQ schema sold as an AI or rich result win | Google stopped showing FAQ rich results on May 7, 2026. Keep FAQs for readers, not for markup |
Chopping pages into tiny chunks | Google: "There's no requirement to break your content into tiny pieces for AI to better understand it" |
Rewriting everything "for AI" | Google: "You don't need to write in a specific way just for generative AI search" |
Hidden instructions in "Summarize with AI" buttons | Microsoft found more than 50 such prompts from 31 companies and treats the practice as "AI Recommendation Poisoning" |
Guaranteed AI placement | No one controls AI answers, and Google's spam policies now cover "attempting to manipulate generative AI responses in Google Search" |
If a Wix site already generates an llms.txt file for you, leave it alone and make sure its description is accurate. Our guide on whether a small business needs an llms.txt file covers the details.
Buying AEO or GEO Services: 6 Questions to Ask First
Quick answer: ask what the provider will change on your site, what they'll do off it, how they'll measure each job, and what's included that good SEO doesn't already cover. Walk away from guarantees and from llms.txt or schema sold as the strategy.
Which of these tasks isn't already part of good SEO? A useful answer names off-site work: mentions, listings, and reviews on platforms beyond Google.
How will you measure AI visibility? Look for named tools (Search Console, Bing Webmaster Tools, analytics) plus a prompt log with repeat runs, not one screenshot.
Which AI tools matter for my customers? For a local business, Google's AI features and Maps usually come first, then ChatGPT, Gemini, and Copilot.
What will you change on my site in the first month? Expect specific pages, not a general "AI optimization."
Who owns the listings, profiles, and accounts you create? You should, in your business's name.
What happens if the prompt log hasn't moved after 90 days? A good provider has a plan for that conversation before it happens.
Red flags:
A guaranteed spot in ChatGPT or AI Overviews
An llms.txt file or "AI schema" presented as the main deliverable
Separate price lines for SEO, AEO, and GEO covering the same page edits
Reports that show AI "visibility scores" but never calls, bookings, or form fills
Frequently Asked Questions
Quick answer: SEO, AEO, and GEO overlap heavily, Google treats the AI versions as SEO, and a small business needs one plan with three jobs rather than three providers.
What is the difference between AEO, GEO, and SEO?
SEO gets your pages crawled, indexed, and ranked in search results. AEO shapes a page so its answer can be lifted whole into AI Overviews, featured snippets, or voice answers. GEO gets your business named or cited inside answers that AI tools such as ChatGPT, Gemini, and Perplexity write themselves. All three depend on the same crawlable, useful website.
Do I need three different agencies for SEO, AEO, and GEO?
No. The jobs share most of their work, so splitting them across providers usually means paying twice for the same page edits. Look for one plan that covers the site foundation, answer-first writing, and the off-site work of listings, reviews, and mentions, with a separate scoreboard for each job.
Is GEO replacing SEO?
No. GEO depends on SEO. Google says optimizing for its generative AI features is still SEO, and AI tools outside Google also search the web before they answer, so pages that can't be found can't be cited. What's changing is emphasis: mentions, reviews, and consistent listings on other platforms matter more than they used to.
Does ranking on Google mean ChatGPT will recommend my business?
Not necessarily. ChatGPT runs its own searches, uses its own crawler, and leans on licensed data such as Yelp listings for local business cards. A strong Google ranking helps, but you also need crawler access for OAI-SearchBot, a complete Yelp page, and mentions on the sites ChatGPT tends to cite.
Is AEO the same as optimizing for voice search?
Voice search is part of AEO's history, but AEO now mostly means being the answer that AI Overviews, featured snippets, and assistants lift from a page. The method is the same for all of them: a clear question, a direct answer in the first sentence or two, and specifics such as prices, places, and time frames.
How much should a small business budget for AEO or GEO?
Treat it as part of your SEO and local marketing budget, not a new line. Most of the work, such as service pages, answer-first writing, listings, and reviews, is SEO work done well. Be cautious of proposals that charge separately for SEO, AEO, and GEO without showing which tasks differ between them.
How long do AEO and GEO take to work?
Crawler and listing fixes can register within days to weeks. Answer-first rewrites show up as pages are recrawled, usually over weeks. GEO work on mentions and reviews builds over months. Track the same questions monthly and judge the trend over a quarter, because AI answers vary from one run to the next.
